REMA
Enabling the universal

use of green hydrogen
why Hydrogen?
Despite the considerable promise held by green hydrogen as a versatile and eco-friendly method for decarbonization, its broad acceptance still encounters constraints. The expense associated with producing green hydrogen persists as a significant hurdle, particularly when contrasted with more economical options rooted in fossil fuels.

Presently, green hydrogen constitutes less than 1% of total hydrogen production. Therefore, it stands as a critical imperative to reduce its cost from the current range of $6 to $12 per kilogram down to $2 per kilogram. Achieving this reduction is essential for rendering it a financially feasible solution and facilitating the transition towards a decarbonized industry.
OUR Technology
REMA's mission is to provide the world with access to cost-effective and high-quality green hydrogen. By using fluid mechanics and Anion Exchange Membranes (AEMs), we combine alkaline electrolyzers lower CAPEX and robustness with Proton Exchange Membrane (PEM) flexibility and higher power density. Our product works at higher temperatures achieving unprecedented efficiencies. REMA is the catalyst for a world powered by practical and affordable green hydrogen.

Our simplified design significantly reduces production costs. It is engineered for scalable manufacturing using standard techniques such as plastic injection molding and other conventional, cost-effective processes.
