GRZ Technologies SA is a spin-off company of the Laboratory of Materials for Renewable Energy (LMER) of EPFL. It aims to commercialize a large-scale hydrogen compressor (HyCo) based on metal hydrides. This technology has the potential to significantly reduce the cost of hydrogen compression. GRZTechnologies SA secured relevant industrial partners: Burckhardt Compression AG, Messer Schweiz AG, Lonza Solutions AG, Schnyder Ingenieure VS AG, LMER and The Ark Foundation joined the consortium with the goal to upscale its metal hydrides compressor in terms of capacity and desorption rate at level which it is suitable for industrial compression. The goal of the present project is to demonstrate the technical and commercial viability of the technology at a relevant scale by developing, building and testing a large-scale metal hydrides compressor to be compared 1:1 with an existing mechanical compressor on the site of Lonza Solutions AG in Visp.
