UK: Aggregate Industries’ Cauldon cement plant in Staffordshire has become the first industrial facility to operate a PRISMA liquid air energy storage system. Green technology developer Innovatium developed the product in collaboration with the University of Birmingham. The supplier says that it can deliver 25% energy savings for air compression and will help Aggregate Industries to realise its 2030 goal of 500kg/t of CO₂ emissions for its cementitious products.

Aggregate Industries sustainability director Kirstin McCarthy said “We are very proud to be the first partner to install the PRISMA system in an operational environment. Aggregate Industries is committed to transitioning to net zero, and supporting innovations like PRISMA is vital in helping us achieve that goal. McCarthy continued “We believe PRISMA can play a major role in addressing the ‘energy trilemma’ of managing energy efficiency, energy cost and energy security, and we're confident that its installation at Cauldon will further prove its decarbonisation credentials - a big step towards full commercialisation of the technology.”
