HiiROC ($34M to develop thermal plasma electrolysis of natural gas for producing clean hydrogen)

HiiROC, a UK cleantech startup founded in 2019, develops Thermal Plasma Electrolysis technology that converts natural gas to clean hydrogen with no CO₂ emissions. This technology is economical, as it is as cheap as Steam Methane Reforming (SMR) without needing Carbon Capture, Utilization, and Storage (CCUS).

Challenges: hydrogen fuel

The majority of the world's hydrogen (over 60 million tons) is currently produced via steam methane reforming (SMR) process, which requires a significant amount of energy input and emits a substantial amount of CO₂. The SMR process emits between 5 and 9 tons of CO₂ per ton of hydrogen (H₂) produced.

HiiROC Technology

HiiROC has developed methane pyrolysis technology that synergistically combines the plasma torch and liquid metal reactor to efficiently convert methane into hydrogen and carbon. This technique produces hydrogen at the same low cost as SMR while emitting no CO₂.
