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.

EU Renewable Energy Transition accelerates as solar and wind overtake gas, cutting coal reliance and boosting REPowerEU goals; falling electricity demand, hydro and nuclear recovery, and grid upgrades drive a cleaner, secure power mix.

Key Points

It is the EU's shift to solar and wind, surpassing gas and curbing coal to meet REPowerEU targets.

✅ Solar and wind supplied 22% of EU electricity in 2022.

✅ Gas fell behind; coal stayed near 16% with no major rebound.

✅ Demand fell; hydro and nuclear expected to recover in 2023.

European countries were forced to accelerate their renewable energy capacity after Russia's invasion of Ukraine sparked a global energy crisis amid a surge in global power demand that exceeded pre-pandemic levels. The EU’s REPowerEU plan aims to increase the share of renewables in final energy consumption overall to 45 percent by the end of the decade.

However, a new report by energy think tank Ember shows that the EU’s green energy transition is already making a significant difference. Solar and wind power generated more than a fifth (22 percent) of its electricity in 2022, pulling ahead of fossil gas (20 percent) for the first time, according to the European Electricity Review 2023.

Europe also managed to avoid resorting to emissions-intensive coal power for electricity generation as a consequence of the energy crisis, even as renewables to eclipse coal globally by mid-decade. Coal generated just 16 percent of the EU’s electricity last year, an increase of just 1.5 percentage points.

“Europe has avoided the worst of the energy crisis,” says Ember’s Head of Data Insights, Dave Jones. “The shocks of 2022 only caused a minor ripple in coal power and a huge wave of support for renewables. Any fears of a coal rebound are now dead.”

Ember’s analysis reveals that the EU faced a "triple crisis" in the electricity sector in 2022, as stunted hydro and nuclear output compounded the shock. "Just as Europe scrambled to cut ties with its biggest supplier of fossil gas, it faced the lowest levels of hydro and nuclear (power) in at least two decades, which created a deficit equal to 7 percent of Europe’s total electricity demand in 2022," the report says. A severe drought across Europe, French nuclear outages as well as the closure of German nuclear outlets were responsible for the drop.

Solar power shines through
However, the record surge in solar and wind power generation helped compensate for the nuclear and hydropower deficit. Solar power rose the fastest, growing by a record 24 percent last year which almost doubled its previous record, with wind growing by 8.6 percent.

Forty-one gigawatts of solar power capacity was added in 2022, almost 50 percent more than the year before. Ember says that 20 EU countries achieved solar records in 2022, with Germany, Spain, Poland, the Netherlands and France adding the most solar capacity.

The Netherlands and Greece generated more power from solar than coal for the first time. Greece is also predicted to reach its 2030 solar capacity target by the end of this year.

EU electricity demand falls
A significant drop in electricity use in 2022 also helped lessen the impact of Europe’s energy crisis. Demand fell by 7.9 percent in the last quarter of the year, despite the continent heading into winter. This was close to the 9.6 percent fall experienced when Europe was in Covid-19 lockdown in mid-2020.

"Mild weather was a deciding factor, but affordability pressures likely played a role, alongside energy efficiency improvements and citizens acting in solidarity to cut energy demand in a time of crisis," the report says.

A ‘coal comeback’ fails to materialize
The almost 8 percent fall in electricity demand in the last three months of 2022 was the main factor in the 9 percent fall in gas and coal generation during that time. However, Ember says that had France’s nuclear plants been operating at the same capacity as 2021, the EU’s fossil fuel generation would have fallen twice as fast in the last quarter of 2022.

The report says: "Coal power in the EU fell in all four of the final months of 2022, down 6 percent year-on-year. The 26 coal units placed on emergency standby for winter ran at an average of just 18 percent capacity. Despite importing 22 million tonnes of extra coal throughout 2022, the EU only used a third of it."

Gas generation was very similar compared to 2021, up just 0.8 percent. It made up 20 percent of the EU electricity mix in 2022, up from 19 percent the year before.

Fossil fuel generation set to fall in 2023
Ember says low-emissions sources like solar and wind power will continue to accelerate in 2023 and hydropower and French nuclear capacity will also recover. With electricity demand likely to continue to fall, it estimates that fossil fuel-generation "could plummet" by 20 percent in 2023.

Gas generation will fall the fastest, Ember predicts, as it will remain more expensive than coal over the next few years. "The large fall in gas generation means the power sector is likely to be the fastest falling segment of gas demand during 2023, helping to bring calm to European gas markets as Europe adjusts to life without Russian gas."

In order to stick to the 2015 Paris Agreement target of limiting global warming to no more than 1.5 degrees Celsius compared to pre-industrial levels, Ember says Europe must fully decarbonize its power system by the mid-2030s. Its modeling shows that this is possible without compromising the security of supply.

However, the report says "making this vision a reality will require investment above and beyond existing plans, as well as immediate action to address barriers to the expansion of clean energy infrastructure. Such a mobilization would boost the European economy, cement the EU’s position as a climate leader and send a vital international message that these challenges can be overcome."

Rhode Island 100% Renewable Electricity by 2030 outlines pathways via offshore wind, retail solar, RECs, and policy reforms, balancing decarbonization, grid reliability, economics, and equity to close a 4,600 GWh supply gap affordably.

Key Points

A statewide plan to meet all electricity demand with renewables by 2030 via offshore wind, solar, and REC policies.

✅ Up to 600 MW offshore wind could add 2,700 GWh annually

✅ Retail solar programs may supply around 1,500 GWh per year

✅ Amend RES to retain RECs and align supply with real-time demand

A year ago, Executive Order 20-01 cemented in a place Rhode Island’s goal to meet 100% of the state’s electricity demand with renewable energy by 2030, aligning with the road to 100% renewables seen across states. The Rhode Island Office of Energy Resources (OER) worked through the year on an economic and energy market analysis, and developed policy and programmatic pathways to meet the goal.

In the most recent development, OER and The Brattle Group co-authored a report detailing how this goal will be achieved, The Road to 100% Renewable Electricity – The Pathways to 100%.

The report includes economic analysis of the key factors that will guide Rhode Island as it accelerates adoption of carbon-free renewable resources, complementing efforts that are tracking progress on 100% clean energy targets nationwide.

The pathway rests on three principles: decarbonization, economics and policy implementation, goals echoed in Maine’s 100% renewable electricity target planning.

The report says the state needs to address the gap between projected electricity demand in 2030 and projected renewable generation capacity. The report predicts a need for 4,600 GWh of additional renewable energy to close the gap. Deploying that much capacity represents a 150% increase in the amount of renewable energy the state has procured to date. The final figure could as much as 600-700 GWh higher or lower.

Addressing the gap
The state is making progress to close the gap.

Rhode Island recently announced plans to solicit proposals for up to 600 MW of additional offshore wind resources. A draft request for proposals (RFP) is expected to be filed for regulatory review in the coming months, aligning with forecasts that one-fourth of U.S. electricity will soon be supplied by renewables as markets mature. Assuming the procurement is authorized and the full 600 MW is acquired, new offshore wind would add about 2,700 GWh per year, or about 35% of 2030 electricity demand.

Beyond this offshore wind procurement, development of retail solar through existing programs could add another 1,500 GWh per year. That leaves a smaller–though still sizable–gap of around 400 GWh per year of renewable electricity.

All this capacity will come with a hefty price. The report finds that rate impacts would likely boost e a typical 2030 monthly residential bill by about $11 to $14 with utility-scale renewables, or by as much as $30 if the entire gap were to be filled with retail solar.

The upside is that if the renewable resources are developed in-state, the local economic activity would boost Rhode Island’s gross domestic product and local jobs, especially when compared to procuring out-of-state resources or buying Renewable Energy Credits (RECs), and comes as U.S. renewable electricity surpassed coal in 2022 across the national grid.

Policy recommendations
One policy item that has to be addressed is the state’s Renewable Energy Standard (RES), which currently calls for meeting 38.5% of electricity deliveries with renewables by 2035, even as the federal 2035 clean electricity goal sets a broader benchmark for decarbonization. For example, RES compliance at present does not require the physical procurement of power produced by renewable energy facilities. Instead, electricity providers meet their requirements by purchasing RECs.

The report recommends amending the state’s RES to seek methods by which Rhode Island can retain all of the RECs procured through existing policy and program channels, along with RECs resulting from ratepayer investment in net metered projects, while Nevada’s 50% by 2030 RPS provides a useful interim comparison.

The report also recognizes that the RES alone is unlikely to drive sufficient investment renewable generation and should be paired with programs and policies to ensure sufficient renewable generation to meet the 100% goal. The state also needs to address the RECs created by behind-the-meter systems that add mechanisms to better match the timing of renewable energy generation with real-time demand. The policy would have the 100% RES remain in effect beyond 2030 and also match shifts in energy demand, particularly as other parts of the economy electrify.

Fostering equity
The state also is putting a high priority on making sure the transition to renewables is an equitable one.

The report recommends partnering with and listening to frontline communities about their needs and goals in the clean energy transition. This will include providing traditionally underserved communities with expert consultation to help guide decision making. The report also recommends holding listening sessions to increase accessibility to and understanding of energy system basics.

North Sea Offshore Wind Farms will deliver 150 GW by 2050 as EU partners scale renewable energy, offshore turbines, grid interconnectors, and REPowerEU goals to cut emissions, boost energy security, and reduce Russian fossil dependence.

Key Points

A joint EU initiative to build 150 GW of offshore wind by 2050, advancing REPowerEU, decarbonization, and energy security.

✅ Targets at least 150 GW of offshore wind by 2050

✅ Backed by Belgium, Netherlands, Germany, and Denmark

✅ Aligns with REPowerEU, grid integration, and emissions cuts

Four European Union countries plan to build North Sea wind farms capable of producing at least 150 gigawatts of energy by 2050 to help cut carbon emissions that cause climate change, with EU wind and solar surpassing gas last year, Danish media have reported.

Under the plan, wind turbines would be raised off the coasts of Belgium, the Netherlands, Germany and Denmark, where a recent green power record highlighted strong winds, daily Danish newspaper Jyllands-Posten said.

The project would mean a tenfold increase in the EU's current offshore wind capacity, underscoring how renewables are crowding out gas across Europe today.

“The North Sea can do a lot," Danish Prime Minister Frederiksen told the newspaper, adding the close cooperation between the four EU nations "must start now.”

European Commission President Ursula von der Leyen, German Chancellor Olaf Scholz, Dutch Prime Minister Mark Rutte and Belgian Prime Minister Alexander De Croo are scheduled to attend a North Sea Summit on Wednesday in Esbjerg, 260 kilometers (162 miles) west of Copenhagen.

In Brussels, the European Commission moved Wednesday to jump-start plans for the whole 27-nation EU to abandon Russian energy amid the Kremlin’s war in Ukraine. The commission proposed a nearly 300 billion-euro ($315 billion) package that includes more efficient use of fuels and a faster rollout of renewable power, even as stunted hydro and nuclear output may hobble recovery efforts.

The investment initiative by the EU's executive arm is meant to help the bloc start weaning themselves off Russian fossil fuels this year, even as Europe is losing nuclear power during the transition. The goal is to deprive Russia, the EU’s main supplier of oil, natural gas and coal, of tens of billions in revenue and strengthen EU climate policies.

“We are taking our ambition to yet another level to make sure that we become independent from Russian fossil fuels as quickly as possible,” von der Leyen said in Brussels when announcing the package, dubbed REPowerEU.

The EU has pledged to reduce carbon dioxide emissions by 55% compared with 1990 levels by 2030, and to get to net zero emissions by 2050, with a recent German renewables milestone underscoring the pace of change.

The European Commission has set an overall target of generating 300 gigawatts of offshore energy of by 2050, though grid expansion challenges in Germany highlight hurdles.

Along with climate change, the war in Ukraine has made EU nations eager to reduce their dependency on Russian natural gas and oil. In 2021, the EU imported roughly 40% of its gas and 25% of its oil from Russia.

At a March 11 summit, EU leaders agreed in principle to phase out Russian gas, oil and coal imports by 2027.

New Mexico Energy Transition Act advances renewable energy, battery storage, energy efficiency, and demand response to boost grid reliability during climate change-fueled heatwaves, reducing emissions while supporting solar and wind deployment.

Key Points

A state policy phasing out power emissions, scaling renewables and storage, bolstering grid reliability in extreme heat.

✅ Replaces coal generation with solar plus battery storage

✅ Enhances grid reliability during climate-driven heatwaves

✅ Promotes energy efficiency and demand response programs

While temperatures hit record highs across much of the West in recent weeks and California was forced to curb electricity service amid heat-driven grid strain that week, the power stayed on in New Mexico thanks to proactive energy efficiency and conservation measures.

Public Service Company of New Mexico on Aug. 19 did ask customers to cut back on power use during the peak demand time until 9 p.m., to offset energy supply issues due to the record-breaking heatwave that was one of the most severe to hit the West since 2006. But the Albuquerque Journal's Aug. 28 editorial, "PRC should see the light with record heat and blackouts," confuses the problem with the solution. Record temperatures fueled by climate change – not renewable energy – were to blame for the power challenges last month. And thanks to the Energy Transition Act, New Mexico is reducing climate change-causing pollution and better positioned to prevent the worst impacts of global warming.

During those August days, more than 80 million U.S. residents were under excessive heat warnings. As the Journal's editorial pointed out, California experienced blackouts on Aug. 14 and 15 as wildfires swept across the state and temperatures rose. In fact, a recent report by the University of Chicago's Climate Impact Lab found the world has experienced record heat this summer due to climate change, and heat-related deaths will continue to rise in the future.

As the recent California energy incidents show, climate change is a threat to a reliable electricity system and our health as soaring temperatures and heatwaves strain our grid, as seen in Texas grid challenges this year as well. Demand for electricity rises as people depend more on energy-intensive air conditioning. High temperatures also can decrease transmission line efficiency and cause power plant operators to scale back or even temporarily stop electricity generation.

Lobbyists for the fossil fuel industry may claim that the service interruptions and the conservation requests in New Mexico demonstrate the need for keeping fossil-fueled power generation for electricity reliability, echoing policy blame narratives in California that fault climate policies. But fossil fuel combustion still is subject to the factors that cause blackouts – while also driving climate change and making resulting heatwaves more common. After an investigation, California's own energy agencies found no substance to the claim that renewable energy use was a factor in the situation there, and it's not to blame in New Mexico, either.

New Mexico's Energy Transition Act is a bold, necessary step to limit the damage caused by climate change in the future. It creates a reasonable, cost-saving path to eliminating greenhouse gas emissions associated with generating electricity.

The New Mexico Public Regulation Commission properly applied this law when it recently voted unanimously to replace PNM's coal-fired generation at San Juan Generating Station with carbon-free solar energy and battery storage located in the Four Corners communities, a prudent step given California's looming electricity shortage warnings across the West. The development will create jobs and provide resources for the local school district and help ensure a stronger economy and a healthier future for the region.

As we expand solar and wind energy here in New Mexico, we can help ensure reliable electricity service by building out greater battery storage for renewable energy resources. Expanding regional energy markets that can dispatch the lowest-cost energy from across the region to places where it is needed most would make renewable energy more available and reduce costs, despite concerns over policy exports raised by some observers.

Energy efficiency and demand response are important when we are facing extraordinary conditions, and proven strategies to improve electricity reliability show how demand-side tools complement the grid, so it is unfortunate that the Albuquerque Journal made the unsubstantiated claim that a stray cloud will put out the lights. It was hot, supplies were tight on the electric grid, and in those moments, we should conserve. We should not use those moments to turn our back on progress.
