Onsite Hydrogen
& High-Efficiency Fuel Cells

We bring onsite green hydrogen production and high-efficiency, high-capacity fuel cell technology to industry and mobility across Europe and LATAM — engineered for superior conversion efficiency and a substantially lower cost of ownership than conventional alternatives.

  • 90–95% conversion efficiency in hydrogen production
  • 10–20% lower operating cost (OPEX) than conventional alternatives
  • Simplified materials and construction for substantially lower capital cost (CAPEX)
  • Fuel cell systems reaching up to 54% electrical efficiency, for mobility and stationary power
  • Under 2% shunt current loss at any load — conventional alkaline systems can lose over 40% at partial load
  • Stays safely clear of the hydrogen/oxygen explosion threshold at every operating point, including partial load
  • Target sectors: steel, refining, ammonia, ports, mobility and e-fuels
Geographic reach

Europe & Latin America.
Where the transition is happening.

Catalhyzia focuses on markets where regulatory pressure, infrastructure investment, and industrial demand converge to create the strongest hydrogen commercial opportunities.

Northern Europe

A mature industrial base undergoing rapid decarbonisation, with some of the world's most ambitious green steel and chemical transition projects. Strong port infrastructure, deep capital markets, and dedicated hydrogen pipeline networks already under construction make this the anchor region for near-term commercial activity — from large-scale industrial decarbonisation to chemical cluster integration and a growing national hydrogen strategy backed by significant public investment.

Mediterranean

Europe's most cost-competitive renewable production region, combining exceptional solar irradiation with emerging hydrogen export infrastructure linking southern producers to northern industrial demand. A strategic hydrogen backbone connecting the peninsula to the rest of the continent is under active development, while abundant sunshine and growing pipeline capacity position this region as both a domestic powerhouse and a future export hub for renewable hydrogen.

Expansion Markets

A diverse set of emerging opportunities spanning offshore wind coupling, abundant onshore renewable resources, and operational reference projects already proving the commercial model. These markets combine strong natural resource endowments — wind, sun, and renewable grid capacity — with growing institutional interest in port-based export infrastructure, positioning them as the next wave of commercial growth once core European markets mature.
