Unlimited low-cost energy storage
In its latest monthly for pv magazine, the International Solar Energy Society (ISES) explains how pumped-hydro energy storage combined with PV power generation could provide 24/7 power to data centres
Rondo Energy’s 100 MWh heat battery powered by 20 MW of onsite solar
Rondo Energy’s 100 MWh heat battery, powered by 20 MW of onsite solar, could store industrial heat by using low-cost grid electricity generated during sunny and windy hours, the company said.
Nearly half of solar capacity will be co-located with storage by 2060, says DNV
DNV’s Energy Transition Outlook 2025 report also predicts that distributed generation solar should begin outpacing utility-scale installations in some parts of the world by 2060. It adds that the levelized cost of electricity for solar is beginning to plateau and is expected to slow to an annual drop below 1% by the 2050s.
Australia becomes world’s third-largest utility battery market
Australia has overtaken the United Kingdom to rank behind China and the United States in utility-scale battery capacity, with 14 GW/37 GWh of projects at or nearing financial close.
Improving sodium-ion battery stability with calcium
Researchers in Japan have adopted a new calcium-doping strategy to improve the stability and electrochemical properties of NFM, a cathode material used in sodium-ion batteries. The new technique enhances crystallinity and increases the interlayer spacing in NFM, resulting in higher performance compared to NFM treated with conventional processes.
The Hydrogen Stream: mixed evidences from Germany’s hydrogen market
Lhyfe has opened its first hydrogen plant outside France in Germany, while the Hamburg Green Hydrogen Hub is advancing plans for a 100 MW electrolyzer at the former Moorburg coal site.
Spain updates grid rules to expand energy storage, renewables integration
Spain has overhauled its grid-access rules to support energy storage, granting hybrid renewables-plus-storage projects equal dispatch priority and full revenue rights for stored electricity.
German lab pilots 20 kV battery system to cut energy losses
Researchers at Dortmund University are testing a high-voltage battery system operating up to 20 kV to reduce energy losses and improve efficiency.
High-rise buildings could soon use gravity energy storage, say researchers
Researchers in Canada have proposed using gravity-based energy storage in high-rise buildings, in combination with photovoltaic facades, small wind turbines, and lithium-ion batteries. Their modeling indicated that this hybrid system could achieve a levelized cost of energy ranging from $0.051/kWh to $0.111/kWh.
Philippines approves world’s largest solar project for grid connection
The Energy Regulatory Commission (ERC) of the Philippines has given the MTerra Solar Project permission to develop its own dedicated transmission facilities and connect to the Luzon grid. The first phase, encompassing 2.5 GW of solar and 3.3 MWh of battery storage, is due for completion in 2026.
