‘Hybridising’ energy storage systems by combining lithium-ion and flow batteries, shares the power and energy application workloads between the two types of battery and can prolong their life expectancy, a representative of Thai engineering firm TSUS Group has said.

The US state of Iowa got its first grid-scale solar-plus-storage system at the beginning of this year, and this has already been followed by the completion of another, larger battery project in the US state this week.

The developer of one of the world’s biggest battery energy storage systems (BESS) installed globally so far will be taking its vanadium redox flow systems into the international market, beginning with a pilot in Belgium.

SaltX Technology and Vattenfall have signed off on a Letter of Intent to lead a pilot program based on SaltX’s large-scale energy storage technology — EnerStore.

Siemens has helped start a smart grid pilot project in Rotterdam that will connect 20,000 homes with renewables and storage facilities.

The latest project to be dubbed “Europe’s largest battery” will be a 50MWh project from Dutch energy supplier Eneco and Japanese conglomerate Mitsubishi Corporation in Jardelund, Germany.

A containerised flow battery dubbed the ‘largest’ such system in the US has been matched for size by another system dedicated last week in Snohomish, Washington.
