BIOMASS ELECTROLYSER
1kg/day Hydrogen Production
Electrolyser stack developed in collaboration with Ki Hydrogen, a UK-based deeptech start-up co-producing hydrogen and biogenic carbon from their patented method of electrolysing waste biomass.
KI HYDROGEN
SSR Engineering supported Ki Hydrogen's scale-up from single cell, lab-scale electrolysers to large active-area, multi-cell stacks designed to operate with the 10L and 100L reactor systems (also developed with SSR Engineering), capable of producing up to 1kgH2/day

KI HYDROGEN TECHNOLOGY OVERVIEW
Ki Hydrogen has developed an innovative biomass electrolysis technology that converts waste biomass feedstock into hydrogen and biogenic carbon.
With an estimated 10 billion tonnes of available lignocellulosic biomass (from agriculture, forestry and industrial waste) that would otherwise decompose, this process provides a cost-effective route to hydrogen production.
Unlike conventional water electrolysis, biomass electrolysis requires 50% less energy, targeting hydrogen production at $2/kg and biogenic CO2 at $100/tonne with an energy consumption of 25 kWh/kgH2.
Following successful lab-scale validation, Ki Hydrogen is now proving the technology at practical reactor sizes.
