Utility Scale Storage

Japanese researchers used supercomputer simulations to reveal how sodium ions form clusters and move within hard carbon anodes, identifying nanopore sizes and transition regions that control diffusion and rate performance in sodium-ion batteries. Their findings offer design guidelines for optimizing hard-carbon anodes to improve energy density, cycling, and commercialization prospects.

EVE Energy says a 200 MW/400 MWh battery energy storage project in China has entered operation, which it describes as the world’s first utility-scale deployment of 628 Ah lithium iron phosphate (LFP) cells.

RenewaFLEXNL, a three-year Dutch initiative led by TNO, aims to accelerate long‑duration energy storage (8–100 h) to reduce grid congestion and better integrate renewable energy. pv magazine spoke with the project coordinator, Iraxte Gonzalez Aparicio, about diverse storage technologies, real-world applications, regulatory guidance, and energy management system tools to support large-scale solar‑plus‑storage deployment in the Netherlands and beyond.

New research finds that battery safety rankings are not universal but highly dependent on application scenarios, and shows that LFP batteries can emit high levels of hydrogen fluoride, challenging their reputation as the “safest” chemistry.

The EU-funded pilot – the first of its kind in Europe – demonstrated the ability of the company’s iron-air LDES technology to deliver multi-day energy storage in a real-world utility environment.

Greece’s energy regulator has launched two new auctions under the Apollo Program, covering up to 200 MW of solar with storage and a separate 400 MW wind tender, marking the scheme’s first operational rollout since becoming law in 2024.

LevelTen Energy says solar and wind power purchase agreement (PPA) prices in Europe continued to fall in the fourth quarter of 2025, with the most competitive percentiles in Spain below €30 ($35.65)/MWh, reflecting strong downward pressure.

The two 15-year power purchase agreements cover a 805 MW and a 195 MW solar project, set for construction this year, that will power data centers in Texas belonging to Google.

Vema Hydrogen has completed two pilot hydrogen wells in Quebec, Canada, while Advait Greenergy and InSolare Energy are moving forward on hydrogen projects spanning exploration, electrolyzers, research, and integrated production.

The European Network of Transmission System Operators for Electricity published a report on instability detection technologies to help countries with high renewable energy shares maintain grid reliability. The study highlights key tools, research priorities, and the need for stakeholder collaboration to advance real-time monitoring and data-driven decision-making.
