Ki Hydrogen develops a biomass‑based electrolyzer that simultaneously produces green hydrogen and biogenic carbon dioxide from renewable electricity and waste organic feedstocks. The system delivers hydrogen at about $2 /kg and CO₂ at $100 /tonne with integrated gas separation, enabling low‑cost, high‑purity feedstocks for steel, chemicals, e‑fuel, and fertilizer production without new infrastructure.

Problem
Heavy industries such as steel, aviation, maritime, and chemicals rely on fossil‑based hydrocarbons, which emit large amounts of CO₂ and lock the sector into high‑cost, carbon‑intensive supply chains. Scaling low‑cost, sustainable alternatives for hydrogen and carbon feedstocks is difficult because conventional electrolyzers produce only hydrogen and require separate, energy‑intensive CO₂ capture processes.
Solution
Ki Hydrogen addresses this gap with a biomass‑based electrolyzer that simultaneously generates green hydrogen and biogenic carbon dioxide from renewable electricity and abundant organic feedstocks. The integrated system produces hydrogen at approximately $2 per kilogram and CO₂ at about $100 per tonne, using only 25 kWh per kilogram of hydrogen and incorporating built‑in gas separation to deliver ready‑to‑use streams. By co‑producing these two fundamental building blocks, the technology enables cost‑effective supply of green hydrogen, food‑grade CO₂, and downstream e‑fuels (e‑SAF, green methanol, green ammonia) without requiring new infrastructure. The approach leverages waste biomass from forestry, agriculture, and breweries, turning otherwise discarded material into high‑value energy carriers for a decarbonised economy.
Target Audience
Primary customers are heavy‑industry producers (steel, refining, chemicals), e‑fuel manufacturers, and large‑scale fertilizer or CO₂‑utilisation facilities seeking affordable, low‑carbon hydrogen and carbon feedstocks.
Features
- Novel biomass electrolyzer that couples water splitting with biomass gasification to co‑produce H₂ and CO₂ in a single unit
