HiiROC

HiiROC develops a plasma-based hydrogen generation technology that produces clean hydrogen and solid carbon through thermal decomposition of methane (methane pyrolysis), without combustion or the use of oxygen. The company's proprietary plasma process splits hydrogen from the carbon in natural gas, transforming methane into hydrogen and solid carbon as a co-product, avoiding the CO2 emissions associated with conventional steam methane reforming. This approach enables low-cost, low-carbon hydrogen production that can be deployed at point of use, eliminating the need for hydrogen transportation and storage infrastructure. The solid carbon byproduct can be used in industrial applications including building materials, steel production, and battery manufacturing, creating additional revenue streams. HiiROC differentiates itself through its plasma-based methane pyrolysis technology which operates at lower temperatures than conventional methods, requires no water, and produces no direct CO2 emissions, positioning it as a bridge between existing natural gas infrastructure and the hydrogen economy. The company targets applications in industrial hydrogen, power generation, transportation fuel, and heating, with strategic partnerships across energy, automotive, and construction materials sectors. Founded in 2019 and headquartered in Hull, United Kingdom, HiiROC has raised approximately $63.2 million in a Series A round backed by Centrica, Hyundai Motor Company, Kia, Wintershall Dea, CEMEX Ventures, CEMEX, HydrogenOne Capital, Melrose, VNG, MarineFifty, TSP Ventures, and Xelerated.
