• Lausanne-based REMA has received a CHF100,000[US$122,000]Tech Seed loan from the Foundation for Innovation and Technology to accelerate development of its green hydrogen production technology.
• The company is developing high-efficiency AEM electrolysers designed for on-site hydrogen production, aiming to significantly reduce costs and eliminate transportation challenges.

Swiss green hydrogen startup REMA has secured a CHF100,000 [US$122,000] Tech Seed loan from the Lausanne-based Foundation for Innovation and Technology (FIT), providing fresh support for the company’s efforts to develop lower-cost electrolyser technology for decentralized hydrogen production.

REMA is focused on designing electrolyser systems that allow industrial users to produce green hydrogen directly at the point of consumption, reducing the need for transportation, storage and logistics infrastructure. The company’s latest electrolyser stack design improves fluid management, operational efficiency and scalability, while its commercial demonstrator is capable of producing approximately one kilogram of hydrogen per day. The newly awarded funding will be used to support team expansion and accelerate technology scaling activities.

The company believes reducing the cost of green hydrogen remains one of the industry's most urgent challenges. Today, green hydrogen accounts for less than 1% of global hydrogen production, largely due to production costs that typically range from US$6 to US$12 per kilogram. REMA argues that costs must fall toward US$2 per kilogram to enable widespread adoption and support the decarbonization of industry, transportation and energy systems.

REMA’s technology combines principles from both alkaline and proton exchange membrane (PEM) electrolysis through the use of Anion Exchange Membranes (AEMs). The approach seeks to deliver the lower capital costs and durability associated with alkaline systems while capturing the flexibility and higher power density typically offered by PEM electrolyzers. Operating at higher temperatures, the company says its design achieves improved efficiency while maintaining operational robustness.

A key element of the technology is a simplified architecture designed for large-scale manufacturing. REMA’s electrolyser components are engineered to be produced using standard industrial techniques such as plastic injection molding and other established manufacturing processes, helping lower production costs and simplify deployment.

By focusing on modular, on-site hydrogen generation, REMA aims to make green hydrogen more practical and economically competitive for industrial customers. The company believes decentralized production, combined with lower-cost electrolyser technology, can help accelerate the transition toward a broader hydrogen economy while reducing dependence on fossil-fuel-based hydrogen production.
