Technology and Performance.
HyET’s electrochemical hydrogen compressor (EHC) is capable of simultaneous silent compression and selective purification of hydrogen gas. Our technology can compress hydrogen up to 1000 bar in a single-stage, is highly effective and scalable to meet customer specifications. As our compressor has no moving parts, it is silent, reliable and low-maintenance. With our technology hydrogen can be compressed and purified in one step. All of this results in lower CAPEX and OPEX compared to conventional mechanical compression.
