Neoen has unveiled plans for a 248 MW/496 MWh battery in Vernou-la-Celle-sur-Seine, east of Paris, that it says will become France’s largest storage asset and the first connected to RTE’s 400 kV transmission network.
Graphene Manufacturing Group said its six-minute-charging graphene aluminium-ion battery cells doubled energy density to 49 Wh/kg, a development that brings the program closer to customer testing later in 2026 and small commercial production in 2027.
Graphene Manufacturing Group said April 15, 2026, that its six-minute-charging graphene aluminum-ion battery cells reached 49 Wh/kg, doubling the company’s December 2025 figure and sharpening the path toward customer testing in 2026 and small commercial production in 2027.
Battery storage has moved from a supporting role to a central grid technology, with the International Energy Agency saying it was the fastest-growing power-sector technology in 2025 and Reuters reporting a rapid industrial pivot toward stationary storage for data centers.
Covalent on April 23 launched Covalent Connect, a platform designed to consolidate advanced materials characterization into one workflow as companies face more complex analysis needs across semiconductors, energy storage and biotech.
The International Energy Agency says battery storage was the fastest-growing power technology in 2025, with global additions reaching 108 GW and lithium-iron phosphate cells accounting for about 90% of deployments.
