Imagine a world where your home dances to the rhythm of the sun,

where the walls hum softly with stored sunshine, and your energy bills shrink like ice under a summer blaze. This isn’t a distant dream or a scene from an eco-utopian novel. It’s the reality awaiting you with a solar panel system equipped with a battery for your home. The concept might sound tech-heavy or financially daunting at first glance, but let me walk you through why it’s more accessible and impactful than you’ve been led to believe.

The heart of the matter lies in harnessing the sun’s power, an abundant source we’ve been basking in but barely tapping into for our energy needs. Solar panels on your roof capture sunlight, converting it into electricity. This, by itself, is a game-changer. But when you add a battery into the mix, you’re not just capturing energy; you’re holding onto it, storing the very essence of sunlight for a rainy day—or, more practically, for nighttime use or during power outages.

Now, picture this: It’s the end of a long day, and the sun has set. Normally, this would mean your solar panels are off the clock. But with a battery system in place, the energy your panels collected and saved while you were out living your life is now ready to be used. It’s like having a reservoir of daylight at your disposal, lighting up your home, powering your appliances, and doing it all without a whisper of guilt about carbon footprints or environmental harm.

Why is this important, you ask? Because we’re at a tipping point. Our planet, our home, is gasping under the weight of pollution and resource depletion. By choosing a solar panel system with a battery for your home, you’re not just cutting down on your utility bills; you’re part of a growing wave of change. It’s a statement, a stand, a commitment to a cleaner, more sustainable way of living that says, “I care about the future.”

But let’s get down to brass tacks. The initial investment can seem steep, but with various incentives, tax breaks, and the undeniable slash in monthly energy costs, the system pays for itself over time. We’re talking about a setup that not only reduces your reliance on the grid but potentially pays you back in energy credits. And with advancements in technology, these systems are becoming more efficient, more affordable, and more user-friendly, making the leap less of a jump and more of a step.

Critics might point out the limitations, like the dependency on weather or the space required for installation. Yet, isn’t there something profoundly empowering about making the most of what your environment offers, about turning limitations into opportunities? Every day, the sun rises, offering energy free for the taking. And every night, if you’ve got a battery, that energy ensures your home remains a beacon of light and comfort.

So, let’s circle back to where we started, to the vision of your home powered by sunlight. It’s not just about being eco-friendly or saving money—though those are significant perks. It’s about independence, about resilience, and about being part of a solution that’s bigger than any one of us. It’s about tapping into the oldest energy source known to mankind and doing it in a way that could redefine how we power our lives.

In embracing solar panels with a battery for your home, you’re not just keeping up with the Joneses. You’re overtaking them, armed with the sun, a battery, and a vision for a brighter, greener future.

Russian invasion catalyst for renewables in Ukraine: minister

By Isabel MALSANG

Paris (AFP) Feb 16, 2024






The wartime destruction of its coalmines and several of its power plants are proving a catalyst for Ukraine’s renewable energy transition, said the country’s Energy Minister German Galushchenko.

Ukraine is also looking to replace some of its lost nuclear energy production, he added.

The minister said moves towards wind and solar power, coupled with the war’s impact on classic energy infrastructure, means that “the green transition should be implemented faster than we expected.”

Russian forces have destroyed 11 coalmines, which they did to weaken Kyiv’s capacity to produce energy, Galushchenko told AFP on the sidelines of an IEE energy summit this week in Paris.

“Of course we would never restart the operations, that’s obvious,” said Galushchenko. “We understand that we will never repair” the destroyed facilities.

Ukraine has eight power plants in non-occupied territory that can run on coal or natural gas, of which three have been knocked out of action.

“We want to phase out coal of course” for climate protection reasons said Galushchenko.

“Transition will happen faster that expected due to war,” he added.

The immediate focus is on wind and solar farms.

Galushchenko said last year Ukraine constructed around 200 megawatts of wind and around 150 megawatts of solar power capacity.

Even if “it’s not a big amount, I can say that this is due to the war,” he said.

Ukraine is also looking to rebuild nuclear power to compensate for production it lost from Zaporizhzhia, Europe’s largest nuclear power plant, since Russian forces occupied the facility in 2022.

That would, Galushchenko said, involve buying two Russian VVER-1000 reactors stored in Bulgaria, initially earmarked for the Belene nuclear power plant decommissioned as a precondition for Bulgaria joining the European Union.

Two AP-1000 type pressurised water reactors would also, he said, come from US nuclear power company Westinghouse for deployment at Khmelnytskyi, in western Ukraine.

Yet some experts are sceptical as to whether that project is viable as new reactors would take at least a decade to come on stream while there are worries the reactors in Bulgaria may prove to be too old.

Galushchenko said expanding nuclear production would also open up possibilities for Ukraine to supply Europe with green hydrogen.

Hydrogen is being looked at as a fuel that could help decarbonise industry and transport as it produces no carbon dioxide when burned, and is green provided it is produced using renewable or nuclear power.

Ukraine has “calculated it will be able to produce three to five million tonnes of hydrogen per year,” Galushchenko said.

“The one question is how to transport this hydrogen … that is the most difficult question.”

Galushchenko said Ukraine’s electricity network was faring better this winter than last year.

“It’s not the same as it was before the previous winter… when we were under almost constant restrictions. Generally, we do not have restrictions in supply of electricity,” he said.

Ukraine can produce up to 18 gigawatts of electricity, he said, which is enough to handle even peak hours of consumption.

And even if Kyiv has had at times to import electricity, international support has enabled it to get by more or less.

With the end of winter approaching they may get through the most demanding season without major restrictions for consumers.

“It’s great news, and due to this we also have a growth in the economy,” said the minister.

Europe Invests in Thermal Energy Storage Innovation

by Robert Schreiber

Berlin, Germany (SPX) Feb 09, 2024






An ambitious international research endeavor, spearheaded by the Martin Luther University Halle-Wittenberg (MLU), is set to revolutionize seasonal thermal energy storage technologies. Titled “INTERSTORES,” this project is at the forefront of designing and integrating novel storage systems into our energy infrastructure, marking a significant step forward in the energy transition movement.



Funded under the “Horizon Europe” program, the initiative boasts nearly eleven million euros in support, with MLU receiving approximately 1.5 million euros. This substantial investment underscores the project’s critical role in enhancing the performance and cost-efficiency of thermal energy storage systems, aiming to propel these technologies to market readiness.



Professor Peter Bayer, a geoscientist at MLU and the project lead, highlights the essential challenge renewable energy faces-storage. Particularly in temperate climates, energy, especially in the form of heat, is abundant in summer but scarce in winter. “That is why we need simple and cost-effective solutions so that, for example, the surplus energy from the summer can be used in the winter,” Bayer explains.



Initial systems utilizing water heated by solar energy or waste heat, stored in large underground tanks, demonstrate the concept’s viability. Despite the proven potential of these thermal storage solutions, their widespread implementation is hindered by high investment costs, economic risks, and a lack of practical planning tools. The INTERSTORES project aims to address these barriers through a collaborative effort involving partners from nine countries, each bringing expertise in business, engineering, geosciences, and environmental technology.



A key focus of the project is demonstrating how large storage systems can be constructed in an efficient, cost-effective, and environmentally friendly manner. This effort includes the development of two distinct facilities: one leveraging existing basin infrastructure in Ingolstadt, Germany, and another involving the excavation of a massive cavern near Helsinki, Finland, capable of holding approximately one million cubic meters of water. These demonstration plants offer a unique opportunity to test the technology at full scale, aiming to bridge critical knowledge gaps and provide practical insights for future implementations.



“By including these two demonstration plants in the project, we have the unique opportunity to investigate the technology at full scale. We want to close critical knowledge gaps to create reliable, functionally robust systems and to obtain practical information for specific implementation projects in the future,” concludes Bayer. Through the INTERSTORES project, MLU and its partners are paving the way for a more sustainable and efficient energy future, showcasing the pivotal role of thermal energy storage in the global shift towards renewable resources.

Space reflectors could ensure bright future for solar power farms

by Sophie Jenkins

Glasgow UK (SPX) Feb 06, 2024






Researchers at the University of Glasgow have taken a significant step forward in the quest for sustainable energy solutions with their latest study on the potential of orbiting solar reflectors. Published in the journal Acta Astronautica, their research unveils a pioneering method to augment the energy output of large-scale solar farms by harnessing additional sunlight reflected from space-based mirrors, extending the power generation window beyond sunset.



The paper, a result of advanced computer simulations, outlines the feasibility of deploying 20 gossamer-like reflectors into a 1000-kilometer orbit above Earth. These reflectors, strategically positioned near the planet’s terminator line in a Walker constellation-a satellite arrangement ensuring consistent Earth coverage-could illuminate solar farms with extra sunlight for two hours daily. This novel approach promises to scale up solar energy production, addressing the critical demand for electricity during the early evening hours.



Dr. Onur Celik, a leading figure from the James Watt School of Engineering at the University of Glasgow and the corresponding author of the study, emphasized the growing role of solar power in achieving net-zero goals. He highlighted the rapid decline in solar panel costs as a catalyst for the widespread adoption of solar energy, underscoring the technology’s limitation to daylight hours. “Orbiting solar reflectors present an innovative solution to maximize solar farms’ output, potentially revolutionizing locations and effectiveness of future solar energy projects,” Dr. Celik remarked.



This research is part of SOLSPACE, a groundbreaking initiative spearheaded by the University of Glasgow with a euro 2.5 million grant from the European Research Council under the European Union’s Horizon 2020 program. Professor Colin McInnes, SOLSPACE’s principal investigator, reflects on the historical context of space reflectors, noting their conceptual discussions dating back to the 1920s and practical demonstrations in the early ’90s.



The SOLSPACE project aims to advance these ideas significantly, leveraging modern technological capabilities and the decreasing cost of space launches to propose a feasible, large-scale application of orbital reflector technology for global clean energy services.



The team’s findings suggest that the deployment of 20 such reflectors could produce an additional 728 megawatt-hours of electricity daily, akin to the output of a large solar farm, but without the need for extensive land use or infrastructure development.



This approach not only promises to enhance the efficiency of solar power generation but also offers a sustainable pathway to meet the escalating global energy demand while mitigating climate change impacts.



As the world grapples with the urgent need for clean energy solutions, the University of Glasgow’s research offers a glimpse into the potential of space-based technologies to complement terrestrial efforts in renewable energy generation. The integration of orbiting solar reflectors with solar farms could mark a significant leap in our pursuit of sustainability, demonstrating the untapped potential of space to contribute to Earth’s energy matrix.



The team’s paper, titled ‘A constellation design for orbiting solar reflectors to enhance terrestrial solar energy’, is published in Acta Astronautica. The research was supported by funding from the European Research Council under the European Union’s Horizon 2020 research and innovation programme (grant agreement No. 883730).

NUS develops perovskite nanocrystal scintillators for precise single-proton detection

by Simon Mansfield

Sydney, Australia (SPX) Feb 02, 2024






In a significant leap forward for particle radiation detection technology, researchers from the National University of Singapore (NUS) have introduced an innovative transmissive thin scintillator crafted from perovskite nanocrystals. This novel device is engineered for the real-time tracking and counting of single protons, marking a considerable advancement in the field of particle detection.



At the heart of this breakthrough is the scintillator’s exceptional sensitivity, attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization. This technological innovation is poised to revolutionize a range of scientific and technological domains, including fundamental physics, quantum technology, deep space exploration, and notably, proton cancer therapy.



The quest for precise dose control in proton therapy has catalyzed extensive research into advanced proton detectors. The NUS team’s development stands out by addressing a critical challenge in the field: the need for real-time proton irradiation with single-proton counting accuracy. Unlike traditional particle detectors, which are hampered by their bulkiness or insufficient sensitivity, the NUS-developed scintillator combines ultrathin construction with unparalleled sensitivity.



Led by Professor Liu Xiaogang from the NUS Department of Chemistry and Associate Professor Andrew Bettiol from the NUS Department of Physics, the research team has showcased a thin-film transmissive scintillator that significantly outperforms existing solutions. With a light yield approximately double that of commercially available BC-400 plastic thin-film scintillators and ten times greater than conventional bulk scintillators like LYSO:Ce, BGO, and YAG:Ce crystals, this innovation represents a major step forward in the detection and imaging of single protons.



The scintillators, with a mere thickness of about 5 um, achieve a detection limit of 7 protons per second- a sensitivity that is several orders of magnitude lower than the counting rates deemed clinically relevant. This capability is crucial for applications where precise detection and imaging are paramount.



Moreover, the team has put forward a novel theory regarding the scintillation mechanisms induced by protons in CsPbBr3 nanocrystals, providing significant insights into the fundamental processes underpinning proton scintillation. This understanding is instrumental in harnessing the full potential of perovskite nanocrystals in particle radiation detection.



Utilizing the enhanced sensitivity and fast response time (~336 ps) of these scintillators, the researchers have demonstrated their utility in applications ranging from single-proton tracing and real-time patterned irradiation to super-resolution proton imaging. Impressively, the study achieved a spatial resolution of sub-40 nm for proton imaging, heralding new possibilities for materials characterization, medical imaging, and scientific research.



Professor Liu emphasized the transformative impact of their work, noting, “The breakthrough presented in this work would be of considerable interest to particle radiation detection communities, offering both fundamental insights into new mechanisms of proton scintillation and technical advances in groundbreaking single-ion detection sensitivity using ultrathin proton-transmissive scintillators. In particular, these CsPbBr3 nanocrystal scintillators hold overwhelming promise for advancing detection technology in proton therapy and proton radiography.”



Published in the journal Nature Materials, this research not only contributes to the advancement of detection technologies but also underscores the potential of perovskite nanocrystals in revolutionizing the field. As the scientific community continues to explore the applications of this novel technology, the findings from the NUS team offer a promising path towards improved diagnostics, therapy, and understanding of particle physics.

Bipartisan bill addressing lithium-ion battery fires awaits congressional action

by Dana Forsythe

Washington DC (UPI) Jan 29, 2024






With electric bikes growing in popularity, poorly manufactured lithium-ion batteries and electronics have led to a spate of fires. New congressional legislation aims to fix the problem.

With bipartisan support, members of the House and Senate, including U.S. Rep. Ritchie Torres, D-N.Y., hope to implement safety standards for manufacturing the small but powerful batteries.

According to Torres, deaths associated with e-bike fires have steadily risen since 2019. In an interview with Bronx12 in January, Torres said he was optimistic the bill that provides more safety measures, will move forward.

“I’m confident that we’re going to pass it on a bipartisan basis this year,” he said.

In addition to powering devices like smartphones, laptops and power tools, lithium-ion batteries are in many of the devices used every day, including e-bikes. When these batteries are damaged, they can overheat, catch on fire and potentially lead to explosions.

According to the National Fire Protection Association, e-bike and e-scooter battery fires have been associated with faulty charging equipment, improper charging practices and overloaded electrical circuits.

In December, HR 1797, also known as the “Setting Consumer Standards for Lithium-Ion Batteries Act,” was introduced in the House and referred to the Energy and Commerce Committee.

If passed, it would require the Consumer Product Safety Commission “to promulgate a consumer product safety standard with respect to rechargeable lithium-ion batteries used in micromobility devices, and for other purposes.”

A companion bill in the Senate, S.1008, was introduced March 28 and referred to the Commerce, Science and Transportation Committee.

Gabe Knight, safety policy analyst for Consumer Reports, said that in New York City alone, 267 fires and 18 deaths linked to unsafe lithium-ion batteries in micro mobility devices occurred in 2023.

“Tragically, some of those deaths involved children,” he told UPI. “This marks a significant increase from 2022, in which there were six such deaths in New York City. Nationally, the Consumer Product Safety Commission recorded 19 deaths linked to micro mobility fires from Jan. 1, 2021, through Nov. 28, 2022.”

The U.S. e-bike market size was valued at $1.98 billion in 2022 and is expected to grow some 15.6% a year from 2023 to 2030, according to Grandview Research.

The boom results largely from people adopting electric bikes for daily commutes, growing environmental concern for reducing carbon emissions and the increased support by the U.S. government.

By 2030, the global market for e-bokes is projected to reach just under 77.3 million e-bikes by 2030, according to Statista.

Knight said Consumer Reports strongly supports the bill and has urged every member of Congress to join the effort. The bill has has received endorsement from the Fire Department of New York, the International Association of Fire Chiefs, delivery services like GrubHub and Doordash, and organizations like PeopleForBikes.

“Some people see all e-bikes as dangerous and others will understand that some are safer than others, said Brandale Randolph, CEO and founder of the 1854 Cycling Co., an electric bike manufacturer based in Boston.

The company is preparing to deliver the Bowditch e-bike to law enforcement agencies this summer.

“The e-bike fires are very similar to the fires happening with low quality scooters, hoverboards and even fully electric vehicles in that companies are looking for lower-cost ways of making lithium-Ion based storage systems,” Randolph said.

Randolph said his company has transitioned away from lithium-ion batteries and developed “safer higher quality energy systems,” which has priced them out of the retail market.

Kevin Cox, President of Electra Bicycle Co., said his firm has focused on safety and aesthetics with its most recent lines of e-bikes. Electra makes a wide variety of e-bikes from cruisers to commuter models like the Ponto Go!

“Motors and batteries that have undergone testing and meet U.S. and global regulatory standards are a must, as are quality components and safety features,” Cox said. “Consumers must make sure their e-bike or any e-bike they are thinking of purchasing is equipped with a battery that is UL2849 certified.”

UL 2849 is “the standard for electrical systems for e-Bikes, for the electrical system of any powered bicycle sold, distributed, leased or rented in New York City,” according to Consumer Product Safety Commission.

In addition , Cox said, riders should only use the manufacturer’s battery charger that came with their e-bike and store the bike in a cool, dry place when put away for long periods of time.

“While many bikes these days are sold online, it’s essential consumers know whether their local bike shop can provide the necessary support and service for their new purchase,” he said.

“E-bikes are more complex and will require additional servicing to keep them in the best and safest condition. Pay attention to who you buy an e-bike from. This purchase should be no different than any other large purchase one would make.”

Innovative chiral molecule strategy boosts perovskite solar cell efficiency

by Simon Mansfield

Sydney, Australia (SPX) Jan 29, 2024






In the dynamic world of solar energy, metal halide perovskite solar cells (PSCs) have recently marked a significant milestone, with their power conversion efficiency (PCE) reaching an impressive 26.1%, inching closer to the efficiency levels of traditional crystalline silicon cells.



This achievement is particularly notable given the relatively short time span of just over a decade in which PSCs have developed. The latest research indicates that PSCs could potentially exceed a 30% PCE threshold, a development that could revolutionize solar energy technology.



The recent advancements in PSC technology primarily hinge on the quality of perovskite films used in these cells. The goal is to minimize defect density and achieve exceptional homogeneity in the films, thereby enhancing the overall performance of the solar devices.



Traditionally, the process of creating high-quality perovskite films involves introducing specific molecules during the film’s crystallization phase. These molecules help reduce defects or prevent excessive components in the films, a process known as passivation.



However, conventional passivation strategies in perovskite photovoltaics, typically involving the ABX3 structure, have their limitations. These limitations arise from the interactions between the passivation molecules and the perovskite sites, labeled as A, B, and X.



At the forefront of this research is Prof. Wang’s group from Soochow University, who have introduced a novel method for manipulating the crystal orientation of metal halide perovskites. Their approach involves using chiral molecules to establish a quantified strong force with formamidine (FA) ions in the perovskite, known as the magnetic dipole moment. This method addresses a critical issue in conventional perovskite film crystallization, where the production of a phase harmful to the device, termed the ‘d phase,’ is inevitable.



The use of chiral passivation molecules alone can regulate the composition of perovskite films but is insufficient to ensure an orderly overall structure. However, the application of an external magnetic field, leveraging the spin-orbit coupling effect, enhances this interaction. This allows for the precise adjustment of crystal orientation in the perovskite film while optimizing its composition.



Collaborating with Ilhan Yavuz and his team at Marmara University, Prof. Wang’s group has provided theoretical and computational support for this strategy. This collaboration has demonstrated the feasibility and effectiveness of this approach from both theoretical and experimental perspectives.



In contrast to conventional passivation strategies that involve the direct implementation of organic molecules, this new method significantly increases the interaction energy between chiral molecules and perovskites. This improvement ensures more effective crystallization regulation and achieves a uniform perovskite film.



The Shanghai Synchrotron Radiation Facility, with contributions from Xingyu Gao and colleagues, used in situ crystallization process detection technology to observe a clear and comprehensive improvement in the quality of perovskite films under this synergistic effect.

Revolution in low-light imaging with integrated photovoltaic and photodetector organic device

by Riko Seibo

Seoul, South Korea (SPX) Jan 26, 2024






In a significant advancement in organic-based optoelectronic technology, the Korea Institute of Science and Technology (KIST), in collaboration with experts from Korea University and Ewha Womans University, has developed an innovative device that uniquely combines the functions of organic photovoltaic cells (OPVs) and organic photodetectors (OPDs). This development marks a novel stride in creating low-power, efficient solutions for indoor electronics and wireless IoT sensors.



Historically, the development of OPVs and OPDs has been pursued independently, despite their potential synergies. OPVs are known for their ability to generate electricity even under low-light conditions, while OPDs excel in capturing images. However, their independent development paths have so far limited their practical application in next-generation, miniaturized devices due to efficiency constraints.



The joint research team, led by Dr. Min-Chul Park and Dr. Do Kyung Hwang from KIST, Prof. Jae Won Shim and Prof. Tae Geun Kim from Korea University, and Prof. JaeHong Park from Ewha Womans University, has bridged this gap by integrating these two technologies into a single device. This innovative approach not only enables simultaneous energy harvesting and image capturing but also significantly enhances energy efficiency in indoor environments.



One of the key advancements in this technology is the transformation of the organic semiconductor layer into a multicomponent structure, which has led to a remarkable improvement in the device’s performance. In indoor settings, the device achieves an impressive photoelectric conversion efficiency of over 32%, coupled with a linear dynamic range exceeding 130 dB. This enhancement, particularly in contrast ratio and low-light conditions, allows for clearer image capturing compared to conventional silicon devices, which typically offer a linear dynamic range of around 100 dB.



The research team has also made notable progress by successfully implementing single-pixel image sensing. This system captures ambient light, converts it into electrical energy, and uses this energy for image acquisition. This new photodetector, characterized by its multi-component semiconductor layer, offers versatile applications. It functions not only as a conventional camera but also as an aesthetic and practical element that can be integrated into windows or walls, providing sufficient resolution to discern shapes and movements.



Dr. Min-chul Park from KIST underscored the versatility and potential of this technology, stating, “While primarily functioning as an energy harvester, it can also be applied to detect movement and recognize motion patterns in environments without light.” He expressed optimism about its applications in various sectors, including human-computer interaction (HCI) research and smart indoor environments.



This breakthrough represents a significant step forward in the field of organic optoelectronics. By combining energy harvesting and imaging capabilities, the team has opened new avenues for eco-friendly and efficient solutions in indoor electronic applications. The device’s ability to operate effectively in low-light conditions while providing dual functionality underscores its potential impact on the advancement of wireless IoT sensors and other indoor electronics.

Clean energy largest driver of Chinese GDP growth in 2023: report

By Jing Xuan TENG

Shanghai (AFP) Jan 25, 2024






Clean-energy projects were the largest driver of China’s economic growth in 2023, with Beijing investing nearly as much in decarbonisation infrastructure as total global investment in fossil fuels, according to a report released Thursday.

China is the world’s biggest emitter of greenhouse gases driving climate change, but it is also the top producer of wind and solar energy.

Faced with soaring energy consumption, the country has turbocharged its use of renewables — but also in 2022 approved its largest expansion of coal-fired power plants since 2015, despite President Xi Jinping pledging to peak CO2 emissions between 2026 and 2030.

Investment in “clean-energy” sectors accounted for 40 percent of China’s GDP expansion last year, researchers at the Finland-based Centre for Research on Energy and Clean Air (CREA) said in a new report on Thursday.

“With Chinese investment growing by just 1.5 trillion yuan in 2023 overall, the analysis shows that clean energy accounted for all of the growth, while investment in sectors such as real estate shrank,” the researchers said.

The researchers examined investment in solar power, electric vehicles (EVs), energy efficiency, railways, energy storage, electricity grids, wind, nuclear and hydropower.

These sectors received $890 billion in investment, almost as much as the total global investment in fossil fuels last year, CREA researchers said.

“Without the growth from clean-energy sectors, China’s GDP would have missed the government’s growth target of ‘around 5 percent’, rising by only 3.0 percent instead of 5.2 percent,” the researchers found.

“China’s reliance on the clean technology sectors to drive growth and achieve key economic targets boosts their economic and political importance,” the researchers said. “It could also support an accelerated energy transition.”

– EV glut –

They warned, however, that China could soon have excess capacity in the sector, and that “there is a limit to how much solar power, batteries and other clean technology can be absorbed”.

“In order to keep driving growth in investment, clean technology manufacturing would need to not only absorb as much capital as it did in 2023, but keep increasing investment year after year,” the researchers said.

The threat of overcapacity is beginning to trouble Chinese policymakers, with Vice Minister of Industry Xin Guobin saying that some businesses had been “blindly rushing in, and building redundant new energy vehicle projects”.

Xin said at a press conference last week that the government would take measures to crack down on unnecessary EV projects.

Buoyed by years of government subsidies, China’s electric car industry has exploded in the past decade, with homegrown BYD overtaking US carmaker Tesla in electric vehicle sales last quarter.

Between 2014 and the end of 2022, the Chinese government said it had spent more than 200 billion yuan ($28 billion) on subsidies and tax breaks for EV purchases alone.

Companies in other industries are looking to grab a share of the pie, including consumer electronics giant Xiaomi, which unveiled its first electric car model last month.

Chinese EV firms now face problems, however, including “insufficient consumer demand” and trade barriers in other markets, with many businesses still struggling to make a profit, Xin warned at a press conference on Friday.

International Energy Agency chief Fatih Birol warned last week that trade barriers in the clean energy sector could slow down the global energy transition.

Both the United States and European countries have signalled they might adopt more protectionist policies to buttress their own green sectors.

Washington is considering raising tariffs on Chinese EVs, as well as other goods like solar cells, media reports said in December.

EVs are already subjected to a 25 percent import fee introduced on Chinese automobiles during Donald Trump’s administration.

In October, the EU announced a probe into China’s EV subsidies after accusations that the resulting products undercut European competitors.

The bloc is also mulling a separate investigation into Chinese support for its manufacturers of wind turbines.
