Northern Ireland’s Queens University Belfast (QUB) has found that battery-based energy storage can provide inertial response for system reliability much more efficiently, at a lower cost and with substantially reduced emissions than thermal generation. Dr Marek Kubic at Fluence, which is working with QUB, explains.

The UK and Ireland subsidiary of the Virginia-headquartered AES Corporation has signed an agreement with a Northern Irish government agency to build a 100MW battery storage array.
