  • Innovative Steam Drying Tech Might Slash Industrial Energy Use by 80%

    Innovative Steam Drying Tech Might Slash Industrial Energy Use by 80%

    A new drying process engineered by researchers in Germany has the potential to significantly cut industrial energy consumption while aiding companies in transitioning from fossil fuels to renewable energy sources.

    Drying plays a crucial role in manufacturing many everyday items. Industries rely on it to eliminate moisture from materials, ensuring safe storage, further processing, or maintaining product quality. From minerals and cement to food, detergents, paper, straw, lime, couscous, and even insect larvae, many products require drying during production.

    Currently, most industrial drying systems use hot air heated by burning natural gas. Although effective, this method consumes large amounts of energy and produces considerable carbon emissions. It also results in heat wastage, as much of the warm air escapes into the atmosphere after serving its purpose.

    Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology (Fraunhofer IGB) are exploring a cleaner solution through the LowCarbDry project. In collaboration with Evonik Operations GmbH and the Pergande Group, they’ve developed a system that replaces hot air with superheated steam, powered by electricity rather than fossil fuels.

    Superheated steam is steam heated beyond its boiling point, so it contains no liquid water. In this innovative system, the steam circulates within a closed loop rather than being vented into the air, which helps preserve heat inside the system and drastically reduces energy loss. The team claims this method could cut energy requirements for drying by two to four times, depending on the material and drying temperature.

    An additional benefit appears after the drying process. As moisture escapes from the product, the residual steam can be condensed back into water. During condensation, heat is released at temperatures roughly between 90 and 100 degrees Celsius. Instead of letting this heat go to waste, it can be reused for ongoing drying, other industrial processes, or directed into local district heating networks.

    The system also incorporates heat pump technology, which captures low-temperature heat generated during drying and elevates it to higher temperatures for reuse, thus reducing energy demands further and lowering operating costs. Mechanical vapor recompression is another technique used; compressors increase the pressure of excess steam, then condense and recycle it to generate the heat needed for continued drying, boosting efficiency.

    An intelligent control system optimizes the process by scheduling energy-intensive drying phases during periods when renewable electricity generation is high and prices are low. This strategy helps factories maximize green electricity use while minimizing operational expenses.

    Combined, superheated steam, heat pumps, and smart controls could cut energy consumption by up to 80%, presenting a significant opportunity to reduce carbon emissions in industry.

    The researchers have tested this technology across various materials, including mineral raw materials, construction products, organic waste, food, and animal feed. In every case, they observed that product quality was maintained while achieving high energy efficiency. Pilot systems utilizing superheated-steam spray drying are already in operation, bringing this promising technology closer to widespread industrial adoption.

  • Scientists Achieve Record Stability in High-Efficiency Perovskite Solar Cells

    Scientists Achieve Record Stability in High-Efficiency Perovskite Solar Cells

    Scientists have created a new kind of perovskite solar cell that combines high efficiency with durability, marking a significant advancement toward more affordable and powerful solar energy solutions. This innovative design achieved a power conversion efficiency of 27.3%, while retaining over 90% of its initial performance after 770 hours of continuous operation. The research was conducted by a team at Helmholtz-Zentrum Berlin (HZB) in Germany and was published in the journal Joule.

    Perovskite materials have garnered worldwide interest because of their remarkable ability to efficiently convert sunlight into electricity. They are also much cheaper to produce than traditional silicon solar cells and are incredibly lightweight. These advantages point to their potential for future uses, including flexible solar panels that could be integrated into buildings, vehicles, and portable electronics.

    Instead of relying on a single light-absorbing layer, the HZB team developed a triple-junction solar cell, stacking three different perovskite layers. Each layer is tailored to absorb a specific part of the sunlight spectrum, enabling the cell to harness more solar energy and generate more power than single-layer devices. However, constructing such a complex multilayer structure is challenging, as each layer must seamlessly work with the next. A key difficulty lies in creating efficient electrical connections between the middle and bottom layers, where charge transfer occurs without significant energy loss.

    The researchers focused on improving this critical contact point. In most perovskite solar cells, a material called PEDOT:PSS is used to facilitate the flow of positive charges, but it absorbs some light that could otherwise produce electricity and can decrease the long-term stability of the device. To address this, the team experimented with a new material combination, employing a very thin layer of graphene oxide beneath a self-assembled monolayer (SAM), composed of large organic molecules that naturally organize into a uniform single layer.

    They discovered that graphene oxide created a better surface for the SAM to adhere to, forming a more efficient pathway for charge movement within the solar cell. This configuration also minimized energy losses typically seen in such devices. The result was a record-breaking efficiency of 27.3% for an all-perovskite triple-junction cell, making it one of the most efficient ever reported in this category. Most importantly, the device demonstrated impressive stability, maintaining over 90% of its original efficiency after more than 770 hours of continuous operation — a new benchmark for stability in this type of solar cell.

    The team believes this breakthrough is just the beginning. They suggest that further improvements in the quality of the perovskite layers and the interlayer connections could push efficiencies beyond 30%. Although additional research is necessary before these cells reach commercial viability, the progress indicates that perovskite technology is advancing rapidly.

    With higher efficiency, reduced manufacturing costs, lighter weight, and enhanced durability, next-generation perovskite solar cells could become vital in expanding clean energy deployment and decreasing reliance on fossil fuels worldwide.

  • Breaking the Limits: The Future Beyond Lithium-Ion Batteries

    Breaking the Limits: The Future Beyond Lithium-Ion Batteries

    Lithium-ion batteries are the power source for many everyday devices, including smartphones, laptops, and electric vehicles. They’ve played a significant role in shaping modern technology, but now their performance is starting to plateau. As more people adopt electric cars and countries increase reliance on renewable energy sources, researchers are actively seeking batteries that can store more energy, charge faster, last longer, and operate safely.

    A recent review published in Nature Nanotechnology discusses advancements in this area, particularly focusing on lithium metal batteries, an emerging technology showing promise. Dr. Jorge Seminario, a chemical engineering expert, has dedicated years to studying how these batteries function at the atomic and molecular levels. His research aims to better understand the chemical reactions that occur inside a battery during charging and discharging.

    Lithium metal batteries could hold significantly more energy than current lithium-ion models, enabling electric vehicles to have longer ranges and allowing electronic devices to operate for extended periods between charges. They could also revolutionize the way renewable energy is stored, providing a more reliable power supply during cloudy days or periods of low wind.

    However, safety and reliability remain major hurdles. During charging, tiny needle-like structures known as dendrites can form inside the battery. These dendrites can damage the battery, shorten its lifespan, and, in some cases, pose fire risks. To mitigate this, scientists are investigating the battery’s electrolyte—the liquid or gel medium that helps lithium ions move between electrodes. The movement of lithium ions through the electrolyte critically impacts battery performance.

    Dr. Seminario leverages sophisticated computer models to observe how atoms and molecules behave within the electrolyte. By engineering the electrolyte at the molecular level, researchers aim to direct lithium ions to move more uniformly, encouraging the formation of stable lithium layers instead of hazardous dendrites. This approach enhances both safety and battery durability.

    Research indicates that there’s no single material or design feature that can address all battery challenges. Instead, successful development depends on balancing multiple factors, including energy capacity, recharge speed, stability, and safety. This ongoing work involves international collaboration, combining laboratory experiments with high-powered computer simulations. Teams from the US and Germany, among others, are working together to speed up testing and refine new ideas.

    According to Dr. Seminario, the integration of fundamental scientific research and global teamwork is crucial for advancing practical lithium metal batteries. Success in these efforts could lead to more affordable electric vehicles, improved energy storage for renewables, and reduced reliance on fossil fuels—paving the way toward a cleaner, more sustainable future.

  • Innovative Lithium Extraction Reaches 95% Recovery Using Minimal Freshwater

    Innovative Lithium Extraction Reaches 95% Recovery Using Minimal Freshwater

    As worldwide demand for electric vehicles, smartphones, and renewable energy storage grows, so does the need for lithium, a crucial component in modern batteries.

    Researchers at Monash University have developed a new technique that could make lithium extraction more efficient and environmentally friendly. This innovative method achieves about 95% recovery of lithium from salt mixtures while using minimal water and less energy compared to traditional processes.

    Their findings were published in Environmental Science & Technology.

    Most of the world’s lithium is sourced from underground brines—salty waters trapped beneath dry salt lakes. Extracting lithium from these brines is often a slow, resource-intensive process, typically involving large evaporation ponds that consume significant freshwater and take months or even years to yield usable lithium.

    Led by Professor Huanting Wang, Dr. Zhikao Li, and Ph.D. student Pan Liu, the Monash research team took a different route. Instead of directly extracting lithium from liquid brines, they first transformed the brine into solid salt mixtures. They then used common industrial solvents, like ethanol and acetone, to selectively dissolve the lithium-containing salts, leaving many unwanted salts behind.

    This works because different salts dissolve to different extents in various solvents. By exploiting these natural solubility differences, the team was able to efficiently separate lithium without relying on large volumes of freshwater.

    Removing impurities, such as boron and sulfate, is one of the biggest challenges in lithium extraction. The new process effectively filters out these contaminants, producing high-purity lithium suitable for battery manufacturing.

    The researchers also prioritized sustainability by incorporating a solar-powered evaporation system to recover and reuse the solvents. This system uses sunlight to drive the evaporation process, significantly reducing energy consumption.

    The results were remarkable—with over 99% of the solvents recovered and recycled using only solar energy. This approach not only cuts down on environmental impact but also minimizes waste, reduces freshwater use, and lowers energy demands—all while maintaining high lithium recovery rates.

    This breakthrough has already resulted in a patent application, underscoring its potential for commercial use.

    According to the researchers, this technology offers a viable path toward cleaner lithium production, which is increasingly vital as global demand continues to surge. Given the projected needs of electric vehicles and renewable energy systems, developing more sustainable extraction methods is essential.

    If scaled up for industrial manufacturing, this innovative process could help meet future lithium needs while reducing the environmental footprint typically associated with conventional extraction methods.

  • Solar Dilemmas Unveiled

    Solar Dilemmas Unveiled

    May 03, 2026

    KARACHI:

    As the global energy crisis worsens, electricity bills skyrocket, and a widespread yet divided consensus against fossil fuels emerges, there’s an increasing push in the developed nations to transition to cleaner energy sources. Meanwhile, in the developing world, many are reaching similar conclusions—not purely out of environmental concern, but out of economic necessity. Pakistan is no exception. The idea of switching to solar power is on many minds. Some can afford it now, others plan to wait until they save enough or until policy conditions improve.

    Asad from Karachi, the southern port city blessed with abundant sunshine, is among those contemplating solar energy. Over recent months, especially as the energy crisis continues pounding consumers, he has repeatedly jotted down numbers on a scrap of paper. The calculations are straightforward, but acting on them is complicated—especially for someone watching every rupee, with little room for error. Rising tariffs and frequent load-shedding have made the switch seem logical—payback periods seem reasonable, and long-term savings appealing. Yet, when he decided to proceed, the realities around him had shifted, making the move less feasible.

    The net metering policy he had based his calculations on had transitioned to a net billing system. The previously generous buyback rate for surplus electricity was slashed, sometimes to less than a third of its former value. The financial logic that once made solar investment attractive no longer held. Instead of placing an order, Asad hesitated, redoing his calculations and reconsidering his options.

    His experience reflects a rising uncertainty among Pakistani consumers who, until recently, drove solar adoption. Middle-income households like his can still afford the upfront expense, but policy shifts have begun to diminish the incentives that spurred earlier adoption. Beyond this group, a larger segment faces the same challenges—higher electricity costs, rising fuel prices, and unreliable supply—yet remains excluded from solar benefits.

    Over the past few years, solar capacity in Pakistan has increased markedly. According to The Guardian, installations expanded rapidly between 2021 and 2025, sometimes accounting for a notable share of the national energy mix. However, this shift has been driven more by consumer demand than government policy. Faced with rising costs and unreliable power, households and businesses have sought ways to regain control over their energy use.

    Just as solar adoption was picking up momentum, new policies introduced hurdles—import restrictions, extra taxes, and changes to net metering rules—altered the economics. For some, the payback period has lengthened, making the investment less attractive. For others, entry costs have increased significantly.

    Interestingly, other countries have taken different routes: many reduced or eliminated taxes once solar gained popularity to further encourage adoption. Pakistan, by contrast, has seen costs rise at a time of increased demand.

    Simultaneously, relief remains elusive. Fuel prices stay unpredictable, electricity bills continue rising, and most households feel mounting pressure. Although global supply disruptions aren’t directly tied to Pakistan, their ripple effects are felt locally. The country heavily depends on imported fuels, so international shifts influence costs here too.

    While more people turn to solar to cope with these pressures, the energy system itself has not kept pace, slowing progress and causing uneven growth.

    This raises key questions: If solar is expanding, why does Pakistan remain so reliant on imported energy? What barriers prevent solar from advancing further? And who truly benefits from this transition—are some left behind?

    Dependence on Imports

    Despite the talk of a solar revolution, Pakistan’s reliance on imported energy persists and continues to expose economic vulnerability.

    The country has made some strides in integrating renewables, and solar has become more visible recently. Still, when viewed in the broader energy context, the overall shift remains limited.

    Expert economist Dr. Kaiser Bengali, who has extensively studied energy and development issues, notes that the core problem remains unchanged: “Over the past 25 to 30 years, we’ve increased our dependence on imports. Though renewable energy has grown, its share remains minimal—almost negligible in the overall energy landscape. Solar mainly benefits urban, upper-middle-class households.”

    He emphasizes that not just the volume of solar capacity, but who benefits from it, is critical. “Affordability remains a major barrier. Many cannot even meet basic energy needs, let alone afford solar systems or backup solutions.”

    This imbalance sustains the existing structure: even as some consumers turn to solar, Pakistan’s energy system continues to rely heavily on imported fuels. External shocks—global price swings or regional instability—still hit the country swiftly.

    When asked whether Pakistan can cut its fuel import costs in the next five to ten years, Bengali highlights factors beyond internal control. “Much depends on global geopolitics, like conflicts in the Middle East,” he states. “But our vulnerability stems from our own dependency. If we used fewer imported fuels, external shocks would impact us less.”

    Similarly, SDPI energy researcher Dr. Khalid Waleed sees the current transition as incomplete. “Pakistan’s shift to solar is real but not fully systemic,” he says. “What we’re witnessing is mainly a market response to high tariffs, unreliable supply, and fuel price volatility—more of a hedge than a deliberate policy move.”

    He warns that this approach risks creating a fragmented system—shifting reliance from fuels to imported panels, inverters, and storage, without fostering domestic industrial capacity.

    Economic constraints further complicate matters. “With over Rs2 trillion in circular debt in the power sector and limited fiscal space, policymaking tends to prioritize short-term fixes over long-term restructuring,” Waleed adds.

    Overall, Pakistan’s dependence on imported fuels remains a key vulnerability. “Reducing this reliance would lessen external impacts,” Bengali reiterates, underscoring that the current system still leans heavily on imports, limiting the transformative potential of solar power.

    This complex reality means solar is expanding, but the underlying system remains largely unchanged. The question then becomes: if solar continues to grow, why does the wider energy infrastructure look the same? Why does fossil fuel continue to dominate, and what’s really changing beneath the surface?

    System Resistance to Change

    If solar capacity is increasing so rapidly, one would expect a corresponding shift in the overall energy system. But that hasn’t happened.

    Most visible are rooftop and small commercial solar projects in urban centers. Behind the scenes, however, the core structure remains intact.

    Professor Kaleem Ullah, from the US-Pakistan Center for Advanced Studies in Energy at UET Lahore, confirms that Pakistan’s centralised, fossil-intensive power grid has not fundamentally changed. “As of March 2025, thermal power still accounts for roughly 56% of capacity and remains the main source of electricity,” he notes.

    Persistent systemic issues include high transmission and distribution losses, rising circular debt—around Rs2.39 trillion—and underutilized capacity—only about a third of installed power being effectively used. “Solar growth has occurred, but the core architecture remains unaltered,” he says.

    This disconnect explains why solar’s visible expansion doesn’t translate into systemic transformation. Although solar can reduce reliance on fossil fuels in theory, in practice, the entire energy economy remains intertwined with conventional fuels—oil, gas, coal—not just within the power sector but also in transportation, industry, and household uses.

    “The toughest sectors to transition are transportation, heavy industry, and residential gas,” Kaleem states. “While solar can replace daytime electricity quickly, it cannot easily substitute diesel fuel for transport or natural gas for heating.”

    Thus, even as solar adoption rises, the system’s foundation—built on different assumptions—limits how far the transition can go.

    This prompts a vital question: if solar is burgeoning but broader system changes are lagging, what exactly is causing the slowdown? Is it costs, policies, or fundamental systemic constraints?

    Growth but Limited Scale

    If solar is expanding and providing benefits to households and businesses, then why isn’t this growth translating into a broader systemic shift?

    The answer involves multiple factors—policy contradictions, pricing issues, and the inherent design of the energy system.

    SDPI’s Waleed suggests that the main obstacle isn’t the absence of policies but conflicting objectives within existing ones. “Regulatory barriers are rooted more in policy contradictions,” he explains. “On one side, there’s a push for renewables, while on the other, efforts to protect utilities’ revenues and uphold long-term power purchase agreements.”

    This tension results in inconsistent policy signals. For example, each additional rooftop solar installation reduces demand on the grid, which raises per-unit costs due to fixed capacity payments—a feedback loop that discourages full-scale adoption.

    Consequently, the transition is uneven. Middle- and upper-income households tend to adopt solar more readily, whereas lower-income groups remain dependent on increasingly expensive grid power.

    Market analyst Waqas Moosa notes that recent demand surges—especially after import restrictions disrupted supply chains in 2022—resulted in a backlog of demand that is now stabilizing. “Demand is still there,” he says, “but it is being shaped by policy and cost constraints.”

    Component costs, for instance, remain high—an 18% import tax inflates the price of solar parts, pushing a system that should cost around Rs1 million closer to Rs1.2 million, a substantial hurdle for many households.

    Efforts to streamline processes—such as removing licensing fees—have marginal impact. Moosa points out that delays are often caused by central approvals, with application processing still bogged down by bureaucratic inefficiencies dating back to 2015, when regulation was first introduced and then shifted to DISCOs.

    Financing is another major barrier. “Solar is a high-cost investment requiring access to credit,” he says. “Currently, support for financing, especially for middle-income households and small businesses, remains limited.”

    Altogether, the demand for solar exists, technology is available, and the economy’s logic still supports it. But systemic issues—cost, policy inconsistency, and infrastructure—continue to hold back broader, faster deployment.

    The System Isn’t Prepared

    While policy and market factors restrict solar growth, a deeper problem lies in the structure of Pakistan’s energy system itself. It hasn’t been designed to fully integrate large-scale solar.

    A key issue is Pakistan’s reliance on long-term contracts with existing fossil fuel plants. Kaleem Ullah explains, “Many legacy Independent Power Producer (IPP) deals are based on dollar indexation, guaranteed returns, and capacity payments, regardless of whether the plants operate or not.”

    These contracts mean that even if solar decreases daytime costs, the fixed payments for old plants remain, preserving the high cost burden. “Capacity payments have ballooned into trillions of rupees—consumers end up paying for capacity that isn’t always used,” Kaleem notes. “This structure adds renewable energy on top of a system that’s already expensive, without reducing the underlying costs.”

    This creates resistance within the system—rather than welcoming solar, existing incentives hinder its growth.

    Technical infrastructure is another bottleneck. “The biggest challenge isn’t sunlight availability,” Kaleem asserts. “It’s the grid’s capacity to absorb, transmit, and balance solar power effectively.”

    Transmission constraints, weak distribution networks, and slow upgrades limit how much solar the grid can handle. While rooftop and small-scale projects grow quickly, scaling up at the national level remains difficult—mainly because the grid has not kept pace.

    These issues aren’t solely technical; financial limitations are equally critical. Waleed emphasizes that the same fiscal constraints that affect policy also restrict investments in system upgrades like transmission and grid flexibility.

    “Households face high initial costs, and at the government level, limited fiscal space hampers the necessary infrastructure development,” he explains. “This results in a situation where consumer-led growth is happening without sufficient institutional or infrastructural support to sustain it on a large scale.”

    The core challenge isn’t just adding solar capacity; it’s whether the system can accommodate that growth in a way that meaningfully transforms energy production and delivery. If the system remains misaligned, the question arises: who benefits, and who’s left out?

    Who Gains from Solar?

    As solar continues to grow, another crucial issue surfaces—who actually benefits? Initially, the most visible beneficiaries are wealthier households and companies that can afford the upfront expenses.

    However, Moosa warns that focusing solely on early adopters can be misleading. “Typically, wealthier groups are the first to adopt new technology,” he notes. “The important question is how benefits will spread over time.”

    He emphasizes that impact matters more than just distribution. “For some, solar means savings. For others—particularly those with unreliable or no access to electricity—it can be transformative—allowing night-time study, proper food storage, and improved daily life.”

    Nevertheless, inequality persists. Waleed points out that current trends risk deepening existing divides. “Solar adoption is disproportionately skewed toward middle and upper-income households, leaving poorer consumers tied to an increasingly costly grid,” he says.

    This dynamic shifts how costs are shared across the system. “As more people switch to solar, those remaining on the grid shoulder a larger portion of fixed costs,” he explains—raising concerns about equity.

    Additionally, Moosa warns of a “utility spiral”: as wealthier consumers leave the grid for solar, the remaining users face higher charges, potentially pushing the most vulnerable further into energy poverty.

    This underscores that the transition isn’t just about technology—it’s also about system design and fairness. While some gain savings and flexibility, others are excluded or forced to bear increasing costs.

    Ultimately, for solar to be truly inclusive, systemic reforms are necessary. Without them, the shift risks replicating existing inequalities, benefiting a limited segment while leaving many behind.

    Addressing the System Before Scaling Up Solar

    The core insight is clear: solar isn’t lacking momentum. Demand exists, technology is available, and economic reasons support adoption. What’s missing is systemic alignment.

    Waleed asserts that future growth—aiming for a 50-60% renewable share—requires a shift in planning philosophy. “The focus should be on increasing system flexibility—deploying large-scale batteries, modernizing transmission, and digitalizing grid operations,” he suggests. “Confronting the legacy system is crucial—early retirement or repurposing inefficient plants can free capacity and cut costs.”

    Progress is complex, and hurdles remain. “Pakistan’s renewable targets are aspirational under current conditions,” Kaleem warns. “Solar will grow, especially with storage, as consumers seek more reliable options.”

    The fundamental barriers—weak grids, outdated thermal contracts, financial difficulties, and policy inconsistency—limit the scale of potential transformation. “We can make solar larger,” Kaleem agrees, “but to do so as a dominant source, we must first fix our institutions and infrastructure.”

    In the meantime, immediate measures can help make benefits more accessible—for example, passing on cheaper daytime electricity costs to all consumers. Waqas Moosa emphasizes that the advantage of lower daytime rates should be reflected in tariffs, ensuring even non-solar households benefit.

    The overarching reality is that solar will continue to expand. The question is whether the existing energy system can adapt swiftly enough—not just to accommodate growth, but to enable a meaningful transformation that benefits the entire economy.

  • A Gentle Touch to Extend Solar Cell Lifespan

    A Gentle Touch to Extend Solar Cell Lifespan

    A recent study has uncovered an unexpectedly simple way to address one of the primary challenges facing next-generation solar cells. Researchers from Korea University and the University of Surrey demonstrated that merely bringing two specialized solar materials into contact can significantly enhance both their efficiency and longevity—without the need for additional chemicals or coatings.

    This breakthrough, published in Nature Energy, centers on perovskite solar cells, which have gained worldwide interest due to their lower production costs and easier manufacturing compared to traditional silicon panels. Over the past few years, the efficiency of these cells has rapidly improved, making them strong contenders in the solar industry. However, their tendency to degrade quickly—especially when exposed to heat and moisture—has limited their commercial viability.

    The new method addresses this issue through a straightforward approach. Instead of altering the material’s composition, scientists simply placed two different perovskite films in contact with each other. This contact initiated a natural interaction at the boundary, leading to a more organized and stable internal structure throughout the entire layer—not just on the surface.

    This refined structure enhances the performance of the solar cells. When sunlight strikes the material, it produces tiny charged particles that carry energy. In less stable materials, these particles tend to lose energy rapidly as heat. But in the improved material, they last longer and move more efficiently, resulting in higher electricity output. The innovative design achieved a power conversion efficiency of 25.61%, a notably high mark confirmed through independent testing.

    The process, dubbed “contact-triggered cationic interaction” (CCI), involves the rearrangement of internal charged particles upon contact, which reduces tiny defects that can cause energy loss. Using advanced nanoscale imaging techniques, the team visualized these changes directly, confirming that the alignment and structure improved exactly as anticipated.

    Additionally, this new structural stability translates into greater resistance to damage. Stress tests simulating real-world conditions revealed that the treated materials required about twice as much heat energy to break down compared to untreated samples. This indicates that solar panels built using this technique could last significantly longer under everyday conditions.

    The real elegance of this discovery is its simplicity. By controlling how two layers of material touch and interact, scientists can simultaneously boost both the efficiency and durability of perovskite solar cells. Scaling this approach could accelerate the adoption of perovskite technology, offering a more affordable and capable way to produce clean energy in the future.

  • Wind and solar growth slowed in 2022, analysis reveals

    Wind and solar growth slowed in 2022, analysis reveals

    Last year, the progress of planned or ongoing solar and wind projects slowed, raising concerns about whether nations will reach their goal of tripling renewable energy capacity by the end of the decade.

    In 2023, numerous countries committed to increasing their renewable energy capacity threefold by 2030 to combat global warming. However, the growth rate of new wind and solar projects fell to 11% in 2025, down from 22% in the previous year, mainly due to challenges faced by wind development initiatives, according to the Global Energy Monitor (GEM).

    “Wind developers encountered political obstacles and a series of unsuccessful wind power auctions in affluent nations,” explained GEM researcher Diren Kocakusak. U.S. President Donald Trump opposed wind projects and openly disliked renewable energy, but Kocakusak noted that the global slowdown wasn’t linked to any single country.

    GEM’s analysis also revealed that only a small portion of the growth in wind and solar capacity comes from wealthy G7 nations. The focus is shifting convincingly toward emerging and developing economies. China continues to lead the expansion of renewables, contributing approximately a third of worldwide capacity growth in 2025—around 1.5 terawatts—more than the combined increase of the next six countries.

    Despite this impressive growth, it remains insufficient to keep the world on track for the 2030 targets. Even if all announced and planned projects move forward, the world would still fall short. Nearly 40% of these projects experience delays, are put on hold, or canceled altogether, according to GEM.

    Kocakusak emphasized that the goal isn’t impossible to achieve yet. While momentum may be slowing, it’s not due to a lack of potential. There is still enough time for nations to boost capacity, and many unannounced solar projects could be completed before 2030. Wind projects often take longer to develop, but over 3.5 terawatts of wind and solar capacity have been announced without a confirmed start date, which could still help meet the 2030 objective if they are brought online quickly.

    Some developed countries are actively supporting renewable growth. Japan is considering changes to wind auction procedures, and the UK is increasing investments. However, setbacks like reports suggesting Germany might restrict grid access for renewables highlight ongoing challenges.

    Ultimately, whether the 2030 tripling target is met depends on the commitment and effective implementation by governments and developers worldwide.

  • Fossil Fuel Emissions Set to Reach Record Highs by 2025: Study

    Fossil Fuel Emissions Set to Reach Record Highs by 2025: Study

    Global fossil fuel emissions are projected to reach new heights in 2025, according to a recent study published Thursday. The report emphasizes that limiting global warming to below 1.5°C is now virtually “impossible.”

    The annual Global Carbon Budget analyzes human-induced CO2 emissions resulting from fossil fuel combustion, cement manufacturing, and land-use changes like deforestation. These figures are compared to the temperature increase thresholds established in the 2015 Paris Agreement.

    Scientists from around the world discovered that CO2 emissions from fossil fuels are expected to be 1.1% higher in 2025 than last year. Despite widespread efforts to expand renewable energy sources globally, these advances haven’t yet offset the growing energy demand. Emissions from oil, gas, and coal are all anticipated to rise, pushing the total to a record-breaking 38.1 billion metric tons of CO2.

    As countries convene for COP30 in the Brazilian Amazon, new findings indicate only about 170 billion tons of CO2 remain to keep warming within 1.5°C — a limit set in Paris. With current emission rates, that budget will be depleted in roughly four years, making the goal unattainable, according to Pierre Friedlingstein of Exeter University in Britain, who led the study.

    Despite the disappointing outlook, some positive signs are emerging. China’s fossil fuel emissions have largely stabilized this year — particularly coal — which may signal the beginning of a decline in emissions as renewable energy begins to play a larger role. However, due to policy uncertainties, it’s too soon to declare that China has reached its emission peak.

    In the United States, coal-related emissions increased by 7.5%, driven by higher natural gas prices that shifted power generation toward this more polluting fuel. Both the U.S. and the European Union saw upticks in emissions, partly because of cooler winter weather increasing heating demand. Meanwhile, India experienced a smaller rise in CO2 emissions this year, aided by an early monsoon season and rapid growth in renewable energy.

    The study, published in Earth System Science Data, also points to significant progress. Thirty-five countries have managed to cut emissions while growing their economies — double the number from a decade ago. Overall, human activities, including land use changes, are set to produce around 42.2 billion tons of CO2 this year, slightly less than last year, though estimates remain uncertain. Reduced deforestation and fewer destructive fires in South America, partly due to the ending of the intense 2023-2024 El Niño, have contributed to a decrease in land-use emissions.

  • How the SCO Summit Shapes the Global Energy Market

    How the SCO Summit Shapes the Global Energy Market

    China has prioritized energy collaboration during the recent Shanghai Cooperation Organization (SCO) meetings in Tianjin. President Xi Jinping revealed China’s plan to invest in developing 10 gigawatts (GW) of solar power and 10 GW of wind energy within SCO member countries over the next five years.

    This marks a significant boost from the 1 GW of solar and 0.3 GW of wind energy China has invested in SCO nations since 2019. Additionally, there was implied support for the Power of Siberia-2 gas pipeline, which, if constructed, could raise Russia’s share of China’s gas imports to about one-third by the 2030s.

    How will China’s energy investments impact the energy transformation efforts of SCO member states? Does China’s cooperation with Central Asian nations and energy powerhouse Russia hint at a major shift in the global energy scene? Researchers from China, India, Pakistan, and Finland shared insights to explore these questions.

    Lauri Myllyvirta, a senior fellow at the Asia Society Policy Institute and principal analyst at the Centre for Research on Energy and Clean Air, highlighted that China’s recent commitment signals a meaningful step forward in its international energy efforts. Chinese manufacturers have dominated global solar equipment supply for years, although most of these projects have involved little Chinese participation in development or financing. This new pledge offers an opportunity for Chinese energy firms to deepen their involvement beyond just supplying equipment, leveraging their expertise in expanding renewable energy abroad.

    Currently, China mainly participates in overseas clean energy projects through bidding on initiatives already integrated into host countries’ plans. The new commitment could foster more extensive dialogue with partner governments, promoting energy planning that integrates renewable generation with storage, transmission, and manufacturing. Such an approach would bolster the international influence of Chinese developers and empower partner countries to set more ambitious renewable goals.

    Since 2019, China has invested in approximately 10.4 GW of solar and 7.6 GW of wind energy globally. Within SCO nations, investments have been relatively modest—around 1 GW of solar and 0.3 GW of wind—indicating both the current limited scale and substantial potential for expansion in these markets.

    In 2024, numerous SCO countries heavily relied on imported solar panels—Pakistan imported 17 GW, India added roughly 28 GW of wind and solar capacity, and Uzbekistan launched about 1.8 GW of solar projects. While these nations’ growing energy needs make a collective target of 10 GW each for solar and wind over five years relatively small, the potential for growth is significant.

    However, investing in Russia presents reputational, diplomatic, and ethical risks amid its illegal invasion of Ukraine. Engaging more deeply with other SCO members—many of whom seek to diversify energy sources, enhance security, and reduce emissions—could strengthen China’s leadership in clean energy and align with global climate commitments.

    Overall, the 10+10 GW initiative could shift China’s overseas projects from equipment exports and project bidding toward systemic cooperation and strategic energy planning. This shift would support clean energy transitions across SCO countries and reinforce China’s role as a global leader in renewable energy.

    Xie Cheng Kai, Associate at the Schwarzman Scholars Program at Chatham House, pointed out that the SCO summit introduced new platforms for energy and green industry development and proposed a new development bank. While these are still emerging, more tangible advancements are visible in gas pipeline projects and financial cooperation—part of China’s long-term strategy to diversify and strengthen its position in the global energy market.

    The revival of the Power of Siberia-2 pipeline exemplifies this effort. Although details like contracts and timelines remain unconfirmed, a memorandum of understanding (MoU) has reportedly been signed, signaling renewed momentum. If realized, this pipeline could supply 50 billion cubic meters of gas annually and increase Russia’s share of China’s gas imports to roughly one-third by the 2030s. Currently, this project is viewed more as a geopolitical move than a commercial certainty, with its success hinging on negotiations between China and Russia.

    Unlike oil, where China has sought to avoid dependence on a single supplier, it appears willing to accept some concentration in natural gas supply to maintain flexibility, especially given the U.S. dominance in liquefied natural gas (LNG) exports. Overland Russian gas would provide China a strategic hedge against over-reliance on U.S. LNG and Western financial systems supporting LNG trade.

    China’s financial diplomacy is also advancing—Russian energy companies are reportedly allowed to issue renminbi-denominated “panda bonds” in China, which, along with the majority of bilateral trade settled in roubles and renminbi, increases Moscow’s reliance on Chinese financial markets and offers a sanctions-resistant funding avenue for pipelines and LNG operations. This move aligns with China’s strategic aim to promote the international use of the renminbi and reinforce energy security within its financial sovereignty.

    Li Yuxiao, based in Beijing and leading projects at Greenpeace East Asia, emphasized that achieving SCO’s wind and solar energy targets will require active collaboration along the entire supply chain—covering manufacturing, financing, and technology transfer. Despite China’s booming domestic capacity, Chinese investors face obstacles such as limited financial mechanisms, risk coverage, and complex regulatory environments when investing abroad.

    The 10+10 GW goals involve comprehensive industry participation, including knowledge sharing and technology transfer—elements that seem particularly critical to partner countries’ efforts. Effective cooperation could foster local industry development and accelerate regional energy transition efforts.

    Ruchita Shah, an energy analyst at Ember, observed that India’s participation in the SCO reflects an interest in promoting green technology collaboration. While India remains cautious to protect its domestic industry, it is committed to pursuing diversification, technological innovation, and value creation within India—emphasizing technology transfer, finance, and joint research over merely increasing imports.

    India’s domestic manufacturing has expanded rapidly, from 2.3 GW of solar panels in 2014 to a projected 100 GW by 2025. Yet, dependence on Chinese solar cells and battery components persists. India’s energy policies aim to balance rising energy demand with security, focusing on renewable expansion, emissions reduction, and climate commitments toward net-zero by 2070. Its leadership in global clean energy governance continues—highlighted by co-founding the International Solar Alliance, which now includes over 120 countries.

    Omais Abdur Rehman pointed out that this year’s SCO summit, amid shifting global power dynamics, drew notable attention. Under US tariffs and sanctions, SCO member states began signaling interest in alternative global systems. China, especially, saw the summit as an opportunity to expand its influence—hosting its largest SCO gathering to date with 24 participating leaders and outlining broader regional ambitions. Climate cooperation became a key theme, with China proposing a new SCO development bank and pledging significant grants and loans. Russia emphasized multilateralism, but concrete joint climate actions remain limited, especially amid severe climate disasters facing Pakistan and India.

    For Pakistan, the summit may signal an opportunity to pivot toward more sustainable energy strategies, including phased coal retirement and increased collaboration under the China-Pakistan Economic Corridor (CPEC). The launch of CPEC 2.0 and related business initiatives suggest deeper economic and energy ties, focusing on industrial, agricultural, and digital cooperation.

    Despite ongoing tensions between India and Pakistan, climate resilience and environmental cooperation offer a rare avenue for collaboration. The recent floods exposed the critical need for cross-border efforts. However, unresolved tensions and the absence of a joint climate plan at the summit remain obstacles. Still, the SCO provides a platform for dialogue on shared environmental challenges.

    Global carbon dioxide emissions from the energy sector reached unprecedented levels for the fourth consecutive year last year, as the reliance on fossil fuels continued to rise, even while renewable energy sources also saw significant growth, according to the latest annual energy report from the Energy Institute released on Thursday.

    Why This Matters

    The data underscores the hurdles involved in transitioning the global economy away from fossil fuels, especially in light of the ongoing conflict in Ukraine that has altered oil and gas supply routes from Russia, compounded by rising tensions in the Middle East that threaten supply security.

    Last year marked the hottest year on record, with global temperatures surpassing 1.5°C (34.7°F) above pre-industrial levels for the first time.

    By the Numbers

    In 2024, global energy supply experienced a 2% increase, encompassing all energy sources such as oil, gas, coal, nuclear, hydropower, and renewables, marking the first occurrence of simultaneous growth in all energy categories since 2006, the report reveals.

    This uptick in energy supply resulted in a 1% rise in carbon emissions, pushing them beyond the previous year’s record of 40.8 gigatonnes of carbon dioxide equivalent.

    Among fossil fuels, natural gas exhibited the most significant increase in production, ascending by 2.5%. Coal also saw a 1.2% rise, keeping its status as the primary source of energy generation globally, while oil’s growth remained under 1%.

    Wind and solar power expanded by an impressive 16% in 2024, outpacing the total energy demand by a factor of nine, according to the findings.

    Context

    The Energy Institute, which comprises energy professionals and consulting firms like KPMG and Kearney, took over the responsibility of crafting the report from BP last year.

    Experts monitoring progress have indicated that the world is not on track to meet the ambitious goal of tripling renewable energy capacity by 2030, despite the record levels of installations.

    Key Quotes

    “Last year marked another pivotal moment for global energy, driven by escalating geopolitical conflicts,” commented Romain Debarre from Kearney, a co-author of the report.

    “At COP28, a bold strategy was proposed to triple the global renewable energy output by 2030, but advancements have been inconsistent. Despite notable global growth, we still lack the momentum needed,” added Wafa Jafri, a partner at KPMG.

    The COP28 conference, held in Dubai in 2023, resulted in an agreement among nations to shift away from fossil fuels to achieve net-zero emissions by 2050.
