Problem
Green hydrogen production faces significant cost barriers, with prices ranging from $6 to $12 per kilogram, hindering its widespread adoption as a sustainable alternative to fossil fuels. Conventional electrolyzers using polymeric membranes are limited by temperature constraints, while high-temperature electrolysis presents manufacturing and operational challenges.
Solution
REMA is developing a membrane-less electrolyzer technology that leverages fluid mechanics and optimized reactor design to produce green hydrogen at elevated temperatures (145°C) with improved efficiency. By eliminating the need for polymeric membranes, REMA's patented technology reduces production costs and enables the use of cost-effective manufacturing processes. The electrolyzer achieves efficient separation of hydrogen and oxygen through precise electrolyte flow control, enhancing performance without requiring exotic materials. REMA's solution aims to reduce the cost of green hydrogen production to $2 per kilogram, making it a financially viable option for decarbonizing various industries.
Target Audience
REMA's target audience includes industries seeking cost-effective green hydrogen production, such as refueling stations, seasonal storage facilities, and industrial applications, as well as small-scale units for demonstrations, light mobility, and gadgets.
