What we are doing

This project aims to develop and demonstrate a novel metal-hydride based hydrogen compressor. Currently, hydrogen compression accounts for roughly two-thirds of the costs of dispensing compressed hydrogen at refuelling stations. Metal hydrides are alloys that can absorb hydrogen and use waste heat to compress hydrogen.
