World-first 560 C Carnot battery unveiled as SPIC launches ultra-high-temperature heat storage
Chinese state-owned power group SPIC has launched a 1 MW / 4 MWh pilot, showcasing a long-duration energy storage alternative to conventional lithium-ion batteries and compressed air energy storage (CAES).
Germany adds 6.57 GWh of battery storage in 2025, total hits 24 GWh
Germany added an estimated 6.57 GWh of stationary battery storage capacity in 2025, an increase of about 8% year on year, lifting total installed capacity to roughly 24 GWh. Growth was driven by industrial and large-scale systems, even as home storage installations declined alongside weaker rooftop solar demand.
The Hydrogen Stream: RWE commissions 100 MW hydrogen electrolyzer
RWE has started commissioning a 100 MW electrolyzer in Germany to supply renewable hydrogen under long-term contracts, while Hydrogen Utopia International and Hydrogen Systems are advancing plans to build waste-to-hydrogen plants in Saudi Arabia.
Sodium-ion battery cells already near lithium-ion cost parity, set to get cheaper
By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh – cheaper than lithium-ion at 16–22 €/MWh – while also offering higher energy-to-power ratios and high cycle durability, a new research finds.
