Peer-to-peer energy breakthrough could allow solar and wind energy sources to be shared

China Compressed-Air Energy Storage enables grid flexibility using salt caverns in Jiangsu, delivering long-duration storage for wind and solar, 60 MW capacity, dispatchable power, and low-cost, safe, round-the-clock clean energy integration.

Key Points

Stores off-peak power by compressing air in salt caverns, then drives turbines on demand to balance renewables.

✅ 60 MW Jintan plant connects to grid; commercial CAES milestone

✅ Uses salt caverns; low-cost long-duration storage; high safety

✅ Balances wind and solar; improves grid flexibility and reliability

China is set to connect its first commercial compressed-air energy storage plant to the grid as it seeks more ways to harness fast-growing clean power resources, including new hydropower alongside other long-duration options such as gravity power technologies for around-the-clock use.

China Huaneng Group Co. said its Jiangsu Jintan Salt Cave project recently underwent four days of successful trials and is now ready for commercial operations. The 60-megawatt plant will be the largest compressed air energy storage plant built anywhere in the world since 1991, and the first in China outside of small-scale technology demonstration projects, as China's electricity demand patterns remain in flux, according to BloombergNEF.

The plant will use electricity at night when demand is low to pump air into an underground salt cavern. Then, when demand is high during the day, it can release the compressed air at high enough pressure to spin a turbine and produce electricity, aligning with projections that 60% electricity by 2060 could be reached according to industry outlooks.

Underground compressed air is considered one of the least costly forms of long-term energy storage and has low safety concerns, according to BloombergNEF. But its reliance on certain topographical features such as underground caverns may limit wider deployment, a challenge shared by other regions weighing large-scale storage options for reliability. It’s gained a foothold in China, with nearly four gigawatts of projects in the pipeline, while there are less than two gigawatts combined planned in the rest of the world. Shandong province said just this week in this year's work plan that it would build three projects using the technology.

The Jintan salt caves in Jiangsu, China’s second-biggest provincial economy just north of Shanghai, can store about 10 million cubic meters of gas, enough to power four gigawatts of compressed air plants, according to a Science and Technology Daily report from last year. 

Energy storage is a key part of China’s plan to build a larger and more flexible grid as it tries to peak carbon emissions before 2030 and zero them out before 2060, alongside continued nuclear energy development to stabilize baseload supply. The country is adding a world-leading amount of wind and solar power every year, but their intermittency strains grids that need to be able to deliver electricity all the time, spurring interest in green hydrogen as a flexible complement. China has set targets of 30 gigawatts of new-energy storage by 2025 and 120 gigawatts of pumped hydro storage by 2030.

Shanghai Electric PEM Hydrogen R&D Center advances green hydrogen via PEM electrolysis, modular megawatt electrolyzers, zero carbon production, and full-chain industrial applications, accelerating decarbonization, clean energy integration, and hydrogen economy scale-up across China.

Key Points

A joint R&D hub advancing PEM electrolysis, modular megawatt systems, and green hydrogen industrialization.

✅ Megawatt modular PEM electrolyzer design and system integration

✅ Zero-carbon hydrogen targeting mobility, chemicals, and power

✅ Full-chain collaboration from R&D to EPC and demonstration projects

Shanghai Electric has reached an agreement with the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences (the "Dalian Institute") to inaugurate the Proton Exchange Membrane (PEM) Hydrogen Production Technology R&D Center on March 4. The two parties signed a project cooperation agreement on Megawatt Modular and High-Efficiency PEM Hydrogen Production Equipment and System Development, marking an important step forward for Shanghai Electric in the field of hydrogen energy.

As one of China's largest energy equipment manufacturers, Shanghai Electric is at the forefront in the development of green hydrogen as part of China's clean energy drive. During this year's Two Sessions, the 14th Five-Year Plan was actively discussed, in which green hydrogen features prominently, and Shell's 2060 electricity forecast underscores the scale of electrification. With strong government support and widespread industry interest, 2021 is emerging as Year Zero for the hydrogen energy industry.

Currently, Shanghai Electric and the Dalian Institute have reached a preliminary agreement on the industrial development path for new energy power generation and electrolyzed water hydrogen production. As part of the cooperation, both will also continue to enhance the transformational potential of PEM electrolyzed water hydrogen production, accelerate the development of competitive PEM electrolyzed hydrogen products, and promote industrial applications and scenarios, drawing on projects like Japan's large H2 energy system to inform deployment. Moreover, they will continue to carry out in-depth cooperation across the entire hydrogen energy industry chain to accelerate overall industrialization.

Hydrogen energy boasts the biggest potential of all the current forms of clean energy, and the key to its development lies in its production. At present, hydrogen production primarily stems from fossil fuels, industrial by-product hydrogen recovery and purification, and production by water electrolysis. These processes result in significant carbon emissions. The rapid development of PEM water electrolysis equipment worldwide in recent years has enabled current technologies to achieve zero carbon emissions, effectively realizing green, clean hydrogen. This breakthrough will be instrumental in helping China achieve its carbon peak and carbon-neutrality goals.

The market potential for hydrogen production from electrolyzed water is therefore massive. Forecasts indicate that, by 2050, hydrogen energy will account for approximately 10% of China's energy market, with demand reaching 60 million tons and annual output value exceeding RMB 10 trillion. The Hydrogen: Tracking Energy Integration report released by the International Energy Agency in June 2020 notes that the number of global electrolysis hydrogen production projects and installed capacity have both increased significantly, with output skyrocketing from 1 MW in 2010 to more than 25 MW in 2019. Much of the excitement comes from hydrogen's potential to join the ranks of natural gas as an energy resource that plays a pivotal role in international trade, as seen in Germany's call for hydrogen-ready power plants shaping future power systems, with the possibility of even replacing it one day. In PwC's 2020 The Dawn of Green Hydrogen report, the advisory predicts that experimental hydrogen will reach 530 million tons by mid-century.

Shanghai Electric set its focus on hydrogen energy years ago, given its major potential for growth as one of the new energy technologies of the future and, in particular, its ability to power new energy vehicles. In 2016, the Central Research Institute of Shanghai Electric began to invest in R&D for key fuel cell systems and stack technologies. In 2020, Shanghai Electric's independently-developed fuel cell engine, which boasts a power capacity of 66 kW and can start in cold temperature environments of as low as -30°C, passed the inspection test of the National Motor Vehicle Product Quality Inspection Center. It adopts Shanghai Electric's proprietary hydrogen circulation system, which delivers strong power and impressive endurance, with the potential to replace gasoline and diesel engines in commercial vehicles.

As the technology matures, hydrogen has entered a stage of accelerated industrialization, with international moves such as Egypt's hydrogen MoU with Eni signaling broader momentum. Shanghai Electric is leveraging the opportunities to propel its development and the green energy transformation. As part of these efforts, Shanghai Electric established a Hydrogen Energy Division in 2020 to further accelerate the development and bring about a new era of green, clean energy.

As one of the largest energy equipment manufacturing companies in China, Shanghai Electric, with its capability for project development, marketing, investment and financing and engineering, procurement and construction (EPC), continues to accelerate the development and innovation of new energy. The Company has a synergistic foundation and resource advantages across the industrial chain from upstream power generation, including China's nuclear energy development efforts, to downstream chemical metallurgy. The combined elements will accelerate the pace of Shanghai Electric's entry into the field of hydrogen production.

Currently, Shanghai Electric has deployed a number of leading green hydrogen integrated energy industry demonstration projects in Ningdong Base, one of China's four modern coal chemical industry demonstration zones. Among them, the Ningdong Energy Base "source-grid-load-storage-hydrogen" project integrates renewable energy generation, energy storage, hydrogen production from electrolysis, and the entire industrial chain of green chemical/metallurgy, where applications like green steel production in Germany illustrate heavy-industry decarbonization.

In December 2020, Shanghai Electric inked a cooperation agreement to develop a "source-grid-load-storage-hydrogen" energy project in Otog Front Banner, Inner Mongolia. Equipped with large-scale electrochemical energy storage and technologies such as compressed air energy storage options, the project will build a massive new energy power generation base and help the region to achieve efficient cold, heat, electricity, steam and hydrogen energy supply.

Maxeon IBC Solar Factory USA will scale clean energy with high-efficiency interdigitated back contact panels, DOE-backed manufacturing in Albuquerque, utility-scale supply, domestic production, 3 GW capacity, reduced imports, carbon-free electricity leadership.

Key Points

DOE-backed Albuquerque plant making high-efficiency IBC panels, 3 GW yearly, for utility-scale, domestic solar supply.

✅ 3 GW annual capacity; up to 8 million panels produced

✅ IBC cell efficiency up to 24.7% for utility-scale projects

✅ Reduces U.S. reliance on imported panels via domestic manufacturing

Solar energy stands as a formidable source of carbon-free electricity, with the No. 3 renewable source in the U.S. offering a clean alternative to traditional power generation methods reliant on polluting fuels. Advancements in solar technology continue to emerge, with a U.S.-based company poised to spearhead progress from a cutting-edge factory in New Mexico.

Maxeon, initially hailing from Silicon Valley in the 1980s, recently ventured into independence after separating from its parent company, SunPower, in 2020. Over the past few years, Maxeon has been manufacturing solar panels in Mexico, Malaysia, and the Philippines, as record U.S. panel shipments underscored rising demand.

Now, with backing from the U.S. Department of Energy's Loans Programs Office, Maxeon is preparing to commence construction on a new facility in Albuquerque in 2024, amid unprecedented growth in solar and storage nationwide. This state-of-the-art factory aims to produce up to 8 million panels annually, featuring the company's interdigitated back contact (IBC) technology, which has the capacity to generate three gigawatts of power each year. Notably, the entire U.S. solar industry completed five gigawatts of panels in 2022, making Maxeon's endeavor particularly ambitious and aligned with Biden's proposed tenfold increase in solar power goals.

Maxeon's presence in the United States holds the potential to reduce the country's reliance on imported panels, particularly from China. The primary focus will be on providing this advanced technology for utility departments, where pairing with increasingly affordable batteries can enhance grid reliability while shifting away from residential and commercial rooftops.

Maxeon has achieved a remarkable milestone in solar efficiency, with its latest IBC technology boasting an efficiency rating of 24.7%, as reported by PV Magazine.

This strategic move to the United States could be a game-changer, not only for Maxeon's success but also for clean power generation in a nation that has traditionally depended on external sources for its supply of solar panels, as energy-hungry Europe turns to U.S. solar equipment makers for solutions. Matt Dawson, Maxeon's Chief Technology Officer, emphasized the importance of achieving the lowest levelized cost of electricity with the lowest overall capital, a feat that China has accomplished in recent years due to the strength of its supply chain. As energy independence becomes a global concern, solar manufacturing is poised to expand beyond China, with Southeast Asia already showing signs of growth, and now the United States and possibly Europe, including Germany's solar boost during the energy crisis, following suit.

Clean Energy Investment is surging as renewables, electric vehicles, grids, storage, and nuclear outpace fossil fuels, driven by energy security, affordability, and policies like the Inflation Reduction Act, the IEA's World Energy Investment report shows.

Key Points

Investment in renewables, EVs, grids, and storage now surpasses fossil fuels amid cost and security pressures.

✅ $1.7T to clean tech vs just over $1T to fossil fuels this year.

✅ For every $1 in fossil, about $1.7 goes to clean energy.

✅ Solar investment poised to overtake oil production spending.

Investment in clean energy technologies is significantly outpacing spending on fossil fuels as affordability and security concerns, underpinned by analyses showing renewables cheapest new power in many markets, triggered by the global energy crisis strengthen the momentum behind more sustainable options, according to the International Energy Agency's (IEA) latest World Energy Investment report.

About $2.8 trillion (€2.6 trillion) is set to be invested globally in energy this year, of which over $1.7 trillion (€1.59 trillion) is expected to go to clean technologies - including renewables, electric vehicles, nuclear power, grids, storage, low-emissions fuels, efficiency improvements and heat pumps – according to report.

The remainder, slightly more than $1 trillion (€937.7 billion), is going to coal, gas and oil, despite growing calls for a fossil fuel lockdown to meet climate goals.

Annual clean energy investment is expected to rise by 24% between 2021 and 2023, driven by renewables and electric vehicles, with renewables breaking records worldwide over the same period.

But more than 90% of this increase comes from advanced economies and China, which the IEA said presents a serious risk of new dividing lines in global energy if clean energy transitions don’t pick up elsewhere.

“Clean energy is moving fast – faster than many people realise. This is clear in the investment trends, where clean technologies are pulling away from fossil fuels,” said IEA executive director Fatih Birol. “For every dollar invested in fossil fuels, about 1.7 dollars are now going into clean energy. Five years ago, this ratio was one-to-one. One shining example is investment in solar, which is set to overtake the amount of investment going into oil production for the first time.”

Led by solar, low-emissions electricity technologies are expected to account for almost 90% of investment in power generation, reflecting the global renewables share above 30% in electricity markets.

Consumers are also investing in more electrified end-uses. Global heat pump sales have seen double-digit annual growth since 2021. Electric vehicle sales are expected to leap by a third this year after already surging in 2022.

Clean energy investments have been boosted by a variety of factors in recent years, including periods of strong economic growth and volatile fossil fuel prices that raised concerns about energy security, and insights from the IRENA decarbonisation report that underscore broader benefits, especially following Russia’s invasion of Ukraine.

Furthermore, enhanced policy support through major actions like the US Inflation Reduction Act and initiatives in Europe's green surge, Japan, China and elsewhere have played a role.

In Ireland, more than a third of electricity is expected to be green within four years, illustrating national progress.

The biggest shortfalls in clean energy investment are in emerging and developing economies, the IEA added. It pointed to some bright spots, such as dynamic investments in solar in India and in renewables in Brazil and parts of the Middle East. However, investment in many countries is being held back by factors including higher interest rates, unclear policy frameworks and market designs, weak grid infrastructure, financially strained utilities and a high cost of capital.

"Much more needs to be done by the international community, especially to drive investment in lower-income economies, where the private sector has been reluctant to venture," according to the IEA.

Labrador EV Charging Infrastructure faces gaps, with few fast chargers; Level 2 dominates, fueling range anxiety for Tesla and Chevrolet Bolt drivers, despite rebates and Newfoundland's network linking St. John's to Port aux Basques.

Key Points

It refers to the current and planned network of Level 2 and Level 3 charging sites across Labrador.

✅ 2 public Level 2 chargers: Happy Valley-Goose Bay and Churchill Falls

✅ Phase 2: 3 fast chargers planned for HV-GB, Churchill Falls, Labrador City

✅ $2,500 rebates offered; rural range anxiety still deters buyers

Retired pilot Allan Carlson is used to crossing Labrador by air.

But he recently traversed the Big Land in an entirely new way, driving for hours on end in his electric car.

The vehicle in question is a Tesla Model S P100D, which Carlson says he can drive up to 500 kilometres on a full charge — and sometimes even a little more.

After catching a ferry to Blanc-Sablon, Que., earlier this month, he managed to reach Happy Valley-Goose Bay, over 600 kilometres away.

To get there, though, he had to use the public charging station in Blanc-Sablon. He also had to push the limits of what his car could muster. 

But more affordable mass-market electric vehicles don't have the battery power of a top-of-the-range Tesla, prompting the Big Land's first EV owner to wonder when Labrador infrastructure will catch up to the high-speed charging network recently unveiled across Newfoundland this summer.

Phillip Rideout, an electrician who lives in Nain, bought a Chevrolet Bolt EV for his son — the range of which tops out at under 350 kilometres, depending on driving patterns and weather conditions.

He's comfortable driving the car within Nain but said he's concerned about traveling to southern Labrador on a single charge.

"It's a start in getting these 14 charging stations across the island," Rideout said of Newfoundland's new network, "but there is still more work to be done."

The provincial government continues to push an electric-vehicle future, however, even as energy efficiency rankings trail the national average, despite Labradorians like Rideout feeling left out of the loop.

Bernard Davis, minister of environment and climate change, earlier this month announced that government is accepting applications for its electric-vehicle rebate program, as the N.W.T. EV initiative pursues similar goals.

Under the $500,000 program, anyone looking to buy a new or used EV would be entitled to $2,500 in rebates, an attempt by the provincial government to increase EV adoption.

But according to a survey conducted this year by polling firm Leger for the Canadian Vehicle Manufacturer's Association, 51 per cent of rural Canadians found a lack of fast-charging public infrastructure to be a major deterrent to buying an electric car, even as Atlantic EV interest lags overall, according to recent data.

While Newfoundland's 14-charger network, operated by N.L. Hydro and Newfoundland Power, allows drivers to travel from St. John's to Port aux Basques, and 10 new fast-charging stations are planned along the Trans-Canada in New Brunswick, Labrador in contrast has just two publicly available charging locations: one at the YMCA in Happy Valley-Goose Bay and the other near the town office of Churchill Falls.

This is the proposed second phase of additional Level 2 and Level 3 charging locations across Labrador. (TakeChargeNL)
These are slower, Level 2 chargers, as opposed to newer Level 3 charging stations on the island. A Level 2 system averages 50 kilometres of range per hour, and a Level 3 systems can add up to 250 kilometres within the same time frame, making them about five times faster.

Even though all of the fast-charging stations have gone to Newfoundland, MHA for Lake Melville Perry Trimper is optimistic about Labrador's electric future.

Trimper has owned an EV in St. Johns since 2016, but told CBC he'd be comfortable driving it in Happy Valley-Goose Bay.

He acknowledged, however, that prospective owners in Labrador might not be able to drive far from their home charging outlet. 

More promises
If rural skepticism driven by poor infrastructure continues, the urban population could lead the way in adoption, allowing the new subsidies to disproportionately go toward larger population centres, Davis acknowledged.

"Obviously people are not going to purchase electric vehicles if they don't believe they can charge them where they want to be or where they want to go," Davis said in an interview in early September.

Under the provincial government's Phase 2 proposal, Newfoundland and Labrador is projected to get 19 charging stations, with three going to Labrador in Happy Valley-Goose Bay, Churchill Falls and Labrador City, taking cues from NB Power's public network in building regional coverage.

Davis would not commit to a specific cutoff period for the rebate program or a timeline for the first fast-charging stations in Labrador to be built.

"At some point, we are not going to need to place any subsidy on electric vehicles," he said, "but that time is not today and that's why these subsidies are important right now."

Future demand 
Goose Bay Motors manager Joel Hamlen thinks drivers in Labrador could shift away from gas vehicles eventually, even as EV shortages and wait times persist.

But he says it'll take investment into a charging network to get there.

"If we can get something set up where these people can travel down the roads and use these vehicles in the province … I am sure there will be even more of a demand," Hamlen said.

UK electric vehicle sales reached a record high in September, with battery and hybrid cars making up over half of new registrations. SMMT credits carmaker discounts, new models, and a £3,750 EV grant for driving strong demand across the UK market.

Why are UK Electric Vehicle Sales Surging to a Record High?

UK electric vehicle sales are surging to a record high because automakers are offering major discounts, more models are available than ever, and the government’s new £3,750 EV grant is making electric cars more affordable and appealing to both fleets and private buyers.

✅ BEV sales up nearly one-third in September

✅ Over half of all new cars are now electrified

✅ £3,750 EV grants boost consumer confidence

Electric vehicle (EV) sales in the United Kingdom reached a record high last month, marking a significant milestone in the country’s transition to cleaner transportation. According to the latest figures from the Society of Motor Manufacturers and Traders (SMMT), sales of pure battery electric vehicles (BEVs) surged by nearly one-third to 72,779 units in September, while plug-in hybrid registrations grew even faster.

The combined total of fully electric and hybrid vehicles accounted for more than half of all new car registrations, underscoring the growing appeal of electrified transport, alongside global EV market growth, among both businesses and private consumers. In total, 312,887 new vehicles were registered across the country — the strongest September performance since 2020, according to SMMT data.

SMMT chief executive Mike Hawes said the surge in electrified vehicle sales showed that “electrified vehicles are powering market growth after a sluggish summer.” He credited carmaker incentives, a wider choice of models, and government support for helping accelerate adoption, though U.S. EV market share dipped in Q1 2024 by comparison. “Industry investment in electric vehicles is paying off,” Hawes added, even as he acknowledged that “consumer demand still trails ambition.”

The UK government’s new electric car grant scheme has played a significant role in the rebound. The program offers buyers discounts of up to £3,750 on eligible EVs priced under £37,000. So far, more than 20,000 motorists have benefited, with 36 models approved for reductions of at least £1,500. Participating manufacturers include Ford, Toyota, Vauxhall, and Citroën.

Ian Plummer, chief commercial officer at Autotrader, said the grant had given a “real lift to the market,” echoing fuel-crisis EV inquiry surge in the UK. He noted that “since July, enquiries for new electric vehicles on Autotrader are up by almost 50%. For models eligible for the grant, interest has more than doubled.”

While the majority of BEVs — about 71.4% — were purchased by companies and fleets, the number of private buyers has also been increasing. Zero-emission vehicles now account for more than one in five (22.1%) new car registrations so far in 2025, similar to France’s 20% EV share record, highlighting the growing mainstream appeal of electric mobility.

The surge comes amid a challenging backdrop for the automotive sector, even as U.S. EV sales soared into 2024 across the Atlantic. The UK car industry is still reeling from the effects of US trade tariffs and recent disruptions, such as Jaguar Land Rover’s production shutdown following a cyberattack. Despite these hurdles, the strong September figures have boosted confidence in the industry’s recovery trajectory, and EU EV share grew during lockdown months offers precedent for resilience.

Among individual models, the Kia Sportage, Ford Puma, and Nissan Qashqai led overall sales, while two Chinese vehicles — the Jaecoo 7 and BYD Seal U — entered the top ten, reflecting China’s growing footprint in the UK market. Analysts say the arrival of competitively priced Chinese EVs could further intensify competition and drive prices lower for consumers.

With electrified vehicles now dominating new registrations and fresh government incentives in place, industry observers believe the UK is gaining momentum toward its long-term net-zero goals. The challenge, however, remains converting business fleet enthusiasm into sustained private-buyer confidence through affordable models, with UK consumer price concerns still a factor, reliable charging infrastructure, and continued policy support.
