Energy Storage

Repsol and Sunfire are advancing 200 MW of renewable hydrogen projects in Spain, while new collaborations and funding across Europe and India aim to accelerate electrolyzer development and hydrogen infrastructure.

The Finnish start-up says its sand battery technology is scalable from 20 to 500 MWh with charging power from 1 to 20 MW, depending on industrial needs.

Dutch utility Eneco is testing low-noise air-to-water heat pumps from startup Whspr in around 20 homes, aiming to ease installation constraints near property boundaries. The systems reportedly achieve coefficients of performance of up to 5 and show up to 80% noise reduction in laboratory testing.

Sungrow is introducing its large-scale energy storage system, PowerTitan 3.0, to Europe, featuring grid-forming capability, next-generation battery cells, DC coupling for co-located solar projects, and streamlined commissioning to accelerate deployment.

The Dutch start-up, founded by former Tesla leaders, is taking a novel approach to sodium-ion battery technology, optimizing it for integration with solar power plants. Its technology is set to be deployed for the first time in a Dutch solar-plus-storage project later this year.

Envision Energy has launched a fully integrated energy storage solution combining hardware, software, and market-facing AI to optimize performance, safety, and trading. Its “Physical AI” platform embeds intelligence across cells, systems, and operations, enabling predictive maintenance and real-time market participation.

The European Union added 27.1 GWh of battery energy storage capacity in 2025, with utility-scale systems accounting for the majority of new installations as residential storage declined amid lower electricity prices and reduced support schemes, according to a new report from SolarPower Europe.

Pila Energy is offering a slim, sleek home battery that doesn’t need approvals or permits and works in coordination. What’s the catch?

Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.

Mikie Sherrill, governor of the US state of New Jersey, has signed two executive orders directing state regulators to accelerate utility-scale solar, expand community solar to 3 GW and advance up to 750 MW of battery energy storage as part of an effort to contain rising electricity prices and address projected capacity shortfalls.
