Cemex Ventures increased stake in HiiROC hydrogen

HiiROC Demo plant

Cemex Ventures in Madrid, Spain, has increased its stake in UK-based HiiROC. The startup-company has developed a novel proprietary process for the production of low-cost, zero emission hydrogen. The technology ‘Thermal Plasma Electrolysis (TPE)’ is using a fraction of the electricity and cost of water electrolysis. TPE produces valuable, high-energy hydrogen and inert, solid carbon black, without the formation of CO2. The hydrogen can significantly reduce the cement industry’s dependence on fossil fuels.
