The HPS system – which recently completed year-long trials of a 300kW pilot-facility at an 80MW biomass plant in the UK – will initially be developed for use at gas-production plants, with a view to storing surplus power from future large-scale renewables deployments.

The agreement gives Messer exclusive rights to HPS’ LAES technology in return for annual licensing fees and access to its engineering expertise in gas liquefaction technology – a core part of the cryogenic energy-storage process.
