Dutch-based HyET E-Trol has revealed its anion exchange membrane (AEM) electrolysers successfully demonstrated the direct output compressed hydrogen at 200 barG pressure.
The success comes as a milestone for the company as it says the high pressure would alleviate the need for a downstream compressor in the electrolysis process, with hopes of reducing capital expenditure and improving efficiency.
According to the Arnhem firm, the demonstrations proves that high differential pressure electrolysers are feasible, offering the advantages of both AEM and proton exchange membrane (PEM) electrolysers.
