H2Gremm is a Breton technology company, founded in 2019, dedicated to redefining the future of energy by integrating hydrogen into sustainable mobility and enabling energy autonomy for buildings. The company specializes in the development of ultrapure hydrogen production, compression, and distribution micro-stations. A significant innovation is the incorporation of the first 450-bar hydrogen compressor, notable for its silent operation and lack of mechanical movement, into its comprehensive solution.

H2Gremm offers solutions across three primary pillars: Mobility, Building, and Flexibility. For Mobility, it provides refueling solutions for light hydrogen vehicles, catering to diverse applications from bicycles to cars, suitable for domestic, collective, or industrial uses, including dealerships and logistics platforms. Its Building solutions deliver energy autonomy for housing, communities, and SMEs, designed to be adaptable for both new constructions and renovations, with a modular approach aiming for over 80% self-consumption. Furthermore, the company offers Flexibility solutions for energy management, addressing the crucial aspects of load smoothing, phasing, and curtailment.

The core of H2Gremm’s offering is a fully integrated hybrid electric and hydrogen storage solution. This approach is highly modular and adaptable, carefully considering cost, usage, and maintenance constraints. The system is engineered to be innovative through optimized integration, intelligent storage (using batteries for daily needs and hydrogen for seasonal storage), and sophisticated piloting of heat production systems, especially optimized for heat pumps. It is also a responsible solution, promoting the optimized use of renewable energies, complying with modern building standards like RE2020, and aligning with the Green Deal 2050. From a competitive standpoint, H2Gremm's solutions are designed to significantly reduce energy bills, are easy to implement, and require minimal annual maintenance.
