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.”

UK: A consortium comprising Aggregate Industries, Innovatium and the University of Birmingham has gained funding from the Department for Business, Energy and Industrial Strategy (BEIS) to test a liquid air energy storage (LAES) energy efficiency technology under the government’s Industrial Energy Efficiency Accelerator (IEEA) programme. The IEEA programme, administered by the Carbon Trust on behalf of BEIS, will provide nearly Euro0.4m towards delivering a new compressed air system utilising LAES technology from initial laboratory testing to full operation at Aggregate Industries’ Bardon Hill quarry in Leicestershire.

PRISMA (Peak Reduction by Integrated Storage and Management of Air) by Innovatium is a LAES technology that stores energy in liquid air form to provide compressed air, allowing inefficient partially loaded, variable-demand compressors to be turned off, thus improving the total system efficiency by up to 57%. The PRISMA system will bring together a latent energy cold storage tank, filled with a phase change material (PCM) to store thermal energy, and a number of other off-the-shelf components to form a system that will work with Aggregate Industries’ existing compressed air network. The research group says that the integration of the equipment and components in an industrial setting, for the provision of compressed air, has never been attempted before.

“The project will help to address the ‘energy trilemma’ of managing energy efficiency, energy cost and energy security by: significantly improving the energy efficiency of our compressed air system; managing electricity costs by running the compressors out-of-hours, when electricity is cheaper; and helping to smooth and reduce the peak electrical demand on site. We are therefore very excited to be the first industrial partner to install the PRISMA system at our Bardon Hill quarry in Leicestershire,” said Richard Eaton, Energy Manager at Aggregate Industries.

The 24-month project will involve the development of the PCM at the University of Birmingham’s School of Chemical Engineering as well as the design, manufacture and assembly of multiple system components by Innovatium before installation of the system at Bardon Hill. The PRISMA Project has currently only been deployed in a simulated environment. Following successful delivery of the project, this scalable technology has multi-sectoral applications for compressed air systems both in the UK and globally. In the UK, the compressed air market is estimated at 1.3GW of installed electrical capacity across around 4500 sites and over 55,000 individual compressor units.
