H2Gremm - Hydrogen for mobility and low-carbon buildings
H2Gremm designs, manufactures and deploys mini-stations for the production, storage and distribution of green hydrogen, directly on site. Our modular, compact technology makes it possible to use excess photovoltaic electricity to produce hydrogen locally, without transport or losses, for mobility or energy autonomy in buildings.
Designed to be integrated into concrete energy transition projects, our solution meets the challenges of low-carbon building: reducing emissions, optimizing self-consumption, and improving energy resilience.
Thanks to its innovative approach, H2Gremm makes hydrogen accessible to companies, local authorities and real estate players wishing to reduce their carbon footprint while gaining energy independence.
Positive-energy single-family home. Cooperation between Trecobat and H2Gremm as part of the COMEPOS project, coordinated by ADEME, CNRS and CEA MINES Paris Tech.
H2Gremm offers an integrated solution for local production, storage and distribution of green hydrogen, specifically designed for energy autonomy in buildings. The mini-station consists of three compact modules:
- An electrolysis production module (1 to 10 kg H₂/day)
- A module for conversion into electricity and vehicle filling
- A 10 to 100 kg H₂ storage module (from 200 kWh to 2 MWh).
This technology enables surplus renewable electricity (photovoltaic in particular) to be valorized and converted into hydrogen, which is then used for mobility or the production of decarbonated electricity and heat.
