RheEnergise commissions first ‘high density hydro’ long-duration storage in UK
Pilot long-duration energy storage (LDES) project uses low viscosity, denser-than-water fluid. RheEnergise is panning for future projects in 10 MW to 100 MW range, with six to 20 hours of storage capacity.
Five trends for energy storage as global market passes 100 GW
A new report from Wood Mackenzie identifies five key trends that will define the energy storage industry in 2026, including supply chain restructuring and the rise of non-lithium batteries.
Scientists unveil hybrid-energy heat pump combining absorption and compression cycles
Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.
World’s largest compressed-air storage plant switched on in China
New 2.4 GWh adiabatic compressed air energy storage (CAES) plant now operational in in Jiangsu province. The large-scale CAES uses molten salt and pressurized thermal water storage to achieve high efficiency, with power generated through two 300 MW units.

SunWiz market data ranks the manufacturer as the top energy storage supplier in Australia, Ireland, and South Africa.
Volta 2025 battery report shows falling costs driving global BESS growth
The Volta Foundation’s 2025 Battery Report finds battery energy storage system (BESS) deployments exceeded 100 GW for the first time, as turnkey system costs fell sharply and long-duration storage and service agreements continued to evolve.
Germany launches instantaneous reserve market, opening door to storage
Germany has launched a market-based mechanism for procuring instantaneous reserve, allowing inverter-based assets and battery energy storage systems (BESS) to participate for the first time, creating new revenue opportunities while raising questions over long-term profitability and regulatory risk.
Turkey switches on first major solar-plus-storage project
Oze Grup’s Sivrihisar project pairs a 49.2 MW solar plant with 34.1 MWh of battery storage, marking Turkey’s first grid-connected hybrid facility approved under the sustainable finance framework (DGES).
Key takeaways from Solar Energy Expo in Poland
Solar Energy Expo 2026, Poland’s flagship PV-plus-storage trade fair, returned this month with a small show-floor footprint but a sharp focus on flexibility and market reform, as well as the storage, inverter and grid-forming technologies shaping the nation’s next phase of grid integration.
The Hydrogen Stream: EU Commission invites offtakers under Hydrogen Mechanism
The European Commission is advancing market matching for renewable and low-carbon hydrogen by inviting European offtakers to signal supply interest under the Hydrogen Mechanism, while Germany’s electrolysis rollout continues to lag official targets despite new EU-backed funding schemes.
