Core contributor across the entire COSMHYC project series (COSMHYC, COSMHYC XL, COSMHYC DEMO), progressing from concept through scale-up to demonstration.
MAHYTEC SARL
French SME specializing in hybrid hydrogen compression and pressurized storage for refuelling stations and mobility applications.
Their core work
MAHYTEC is a French SME specializing in hydrogen storage and compression technologies. Their core work centers on developing hybrid compressor systems that combine metal hydride and mechanical compression for hydrogen refuelling stations. They provide pressurized hydrogen storage solutions — including containerized, transportable units — for applications ranging from hydrogen mobility infrastructure to portable fuel cell power generators. Their involvement spans from R&D through to full-scale demonstration of hydrogen compression at refuelling sites.
What they specialise in
COSMHYC XL and COSMHYC DEMO explicitly target hydrogen refuelling stations for heavy-duty vehicles and FCEV fleets.
EVERYWH2ERE focused on pressurized, containerized hydrogen storage solutions; storage is integral to COSMHYC work as well.
EVERYWH2ERE project developed transportable PEMFC-based generator sets for urban deployment.
GENESIS project involved life cycle assessment and environmental sustainability analysis of fuel cell and hydrogen systems for aircraft.
How they've shifted over time
MAHYTEC's early H2020 work (2017–2018) focused on portable hydrogen solutions — containerized PEMFC gensets designed for easy transport and installation in cities. From 2019 onward, their focus shifted decisively toward large-scale hydrogen refuelling infrastructure, with the COSMHYC XL and DEMO projects targeting heavy-duty vehicles and FCEV fleets using hybrid compressor technology. This progression from portable units to permanent refuelling stations mirrors the broader hydrogen sector's maturation from pilot concepts to deployment-ready infrastructure.
MAHYTEC is moving toward demonstration and deployment of hydrogen compression for heavy-duty mobility, positioning them as a go-to partner for real-world hydrogen refuelling infrastructure projects.
How they like to work
MAHYTEC operates exclusively as a project participant, never as coordinator — consistent with a specialist SME that contributes deep technical expertise without taking on consortium management overhead. With 31 unique partners across 9 countries in just 5 projects, they work in mid-to-large consortia and appear to be a trusted repeat contributor, especially within the COSMHYC series where they maintained continuity across three successive project phases. This makes them a low-risk, technically focused partner for hydrogen-related consortia.
MAHYTEC has built a network of 31 partners across 9 European countries through 5 projects, primarily within the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) community. Their network is rooted in the hydrogen compression and mobility ecosystem, with strong ties to partners in the COSMHYC consortium series.
What sets them apart
MAHYTEC occupies a rare niche as an SME with deep, demonstrated expertise in hybrid hydrogen compression — specifically the combination of metal hydride and mechanical compressors. Their three-phase involvement in the COSMHYC series (concept → scale-up → demonstration) gives them end-to-end knowledge of this technology from lab to deployment. For anyone building a consortium around hydrogen refuelling infrastructure, MAHYTEC brings proven hardware-level compression expertise that few European SMEs can match.
