REMA

What REMA does

REMA is a Lausanne-based Swiss startup developing membrane-less Anion Exchange Membrane (AEM) electrolyzers for on-site green hydrogen production. The company's core technology applies fluid mechanics to combine the low CAPEX and robustness of alkaline electrolyzers with the flexibility and higher power density of PEM systems, operating at elevated temperatures to achieve higher efficiency. The architecture is simplified for scalable manufacturing using plastic injection molding and conventional processes, with a stated cost target of $2/kg of green hydrogen versus the current $6-12/kg market range.

The product roadmap centers on two standalone plug-and-play units: the REMA Be1 (2.5 kW, ~1 kg H2/day, targeted for small-scale applications) planned for Q3 2025, and the REMA We1 (50 kW, ~1 kg H2/hour, for refueling stations, seasonal storage, and industrial use) planned for Q4 2026. The company is hosted at EPFL and was co-founded by a team of eight including heads of EPFL's Laboratory of Hemodynamics and Cardiovascular Technology and Laboratory of Optics.

REMA operates a direct sales model targeting small and medium-scale hydrogen applications, with initial commercial deployment planned for Western Switzerland via website-driven inquiries, downloadable brochures, and direct contact. To date the company has raised approximately CHF 250,000 in non-dilutive funding (Venture Kick grant of CHF 150,000 in December 2023 and a FIT Tech Seed loan of CHF 100,000 in June 2026) and is not yet generating revenue.

Direct peers

• ITM Power: ITM Power is a UK-based PEM electrolyzer manufacturer deploying multi-megawatt units for industrial decarbonization and refueling - a direct competitor in electrolyzer hardware, with REMA taking share at the smaller, distributed end of the same market.
• Nel ASA: Nel is a global leader in alkaline and PEM electrolyzers serving refueling, industrial, and utility-scale green hydrogen applications, making it a directly comparable electrolyzer hardware supplier competing for the same end-customers as REMA.
• Plug Power: Plug Power manufactures PEM electrolyzers and turnkey green hydrogen systems for mobility, stationary power, and industrial uses, directly overlapping with REMA's product category and refueling-station and industrial segments.
• Enapter: Enapter is the most direct AEM-focused electrolyzer peer; it produces modular, small-to-medium scale AEM electrolyzers targeting on-site green hydrogen production - the same use case and technology family (AEM) as REMA's Be1 and We1 units.

Emerging players

• Electric Hydrogen: Electric Hydrogen is a US-based PEM electrolyzer startup focused on low-cost, large-scale green hydrogen systems for industrial offtakers - an emerging peer competing for the same industrial customer base REMA targets with its medium-scale We1 unit.
• H2 Pro: H2 Pro is an Israeli startup developing novel membrane-less (or E-TAC) electrolyzer technology, the closest emerging-peer analogue to REMA's differentiated membrane-less AEM approach.
• Sunfire GmbH: Sunfire develops high-temperature electrolyzers (SOEC) and fuel cells for green hydrogen and synthetic fuels, making it an emerging comparable in next-generation electrolyzer architectures seeking the same cost-reduction outcomes REMA targets.

Broad incumbents

• Cummins (Accelera by Cummins): Accelera is Cummins' zero-emissions business, including PEM electrolyzer manufacturing and hydrogen fuel cell systems for heavy-duty and industrial customers, placing it as a broad incumbent competitor to REMA in green hydrogen production equipment.
• Thyssenkrupp Nucera: Thyssenkrupp Nucera supplies large-scale alkaline and PEM electrolyzers for industrial and utility-scale green hydrogen plants, making it a broad incumbent peer whose scale and customer base set the competitive bar for entrants like REMA.
