Battery storage

BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory.

Denver-based Peak Energy claims its sodium-ion battery system offers the lowest operating cost of any energy storage technology on the market today.

Global energy company EcoFlow’s latest product, Gateway, is a wall mounted hardware system that can be installed indoors or outdoors and is compatible with third-party inverters and diesel generators as well as EcoFlow’s own extensive product suite.

Switzerland’s Phenogy has launched a megawatt-hour-scale sodium ion energy storage system at a commercial site near Bremen Airport in northern Germany. With this project, the Swiss manufacturer is making its debut on the European energy storage scene, backed by ambitions to develop fully vertically integrated local manufacturing.

New research from the Netherlands showed that renewables and short-term storage can meet around 92.5% of Europe’s electricity demand in future energy scenarios, with the remaining 7.5% being satisfied by green hydrogen. The scientists considered Europe as fully self-sufficient with zero import-export of power or hydrogen, with each of the 37 countries included in the modeling having a self-sufficiency rate of at least 80%.

Spanish startup Nomad Solar Energy and Full&fast have deployed a portable solar-plus-storage system at a Madrid farm to provide off-grid power for irrigation.

Scientists in China have created an optimization technique for an electric vehicle charging station that uses PV, battery storage, and a vehicle-to-grid operation. Considering the uncertainty of PV generation and the randomness of EV load, the system uses two-level optimization, day-ahead and intra-day.

The cell was fabricated with a 2.3 nm-thin layer of gallium oxide, a silver busbar aimed at improving charge collection and silicon nitride anti-reflection coating. It was encapsulated within a watertight 3D-printed box to ensure impermeability.

Scientists have developed a new optimization approach that combines both day-ahead optimization and real-time optimization to improve operations of PV-driven EV charging stations. The framework is based on the autoregressive moving average and the Latin hypercube sampling models.

Nuclear plants generated a record amount of power in 2024, surpassing record set in 2006, but industry optimism is not backed by economic data or investment, says the World Nuclear Industry Status Report 2025.
