PurifHy Projects

The PurifHy project was funded by the Dutch government (TKI Gas) and aimed at enabling to inject renewable methane into the Dutch gas grid.

The methane is produced in two separate processes. One process is biomass gasification and methanation, the other process is the methanation of H2 and CO2. From both processes, HyET’s EHP has reduced the remaining hydrogen concentration down to at least 0.5%, the Dutch limit of the H2 concentration in the natural gas grid.

At the Power2Gas pilot plant of Stedin in Rozenburg, the Netherlands, HyET’s EHP has been integrated and tested for a couple of hundred hours, showing that a recovery rate of 95% is feasible in a field test.
