HiiROC has completed a £26m investment new investors including Melrose Industries, HydrogenOne, Centrica, Hyundai and Kia, to develop its clean hydrogen technology.

An innovative electrolysis process uses thermal plasma to create a “zero CO2 turquoise hydrogen” at a comparable cost to steam methane reforming but without the emissions and using only one fifth of the energy required by water electrolysis.

A solid carbon byproduct, carbon black, has applications ranging from tyres, building materials and as a soil enhancer. Its production using HiiROC’s technology avoids the emissions and pollution inherent in the predominant oil furnace manufacturing process.

The modular units have practical applications from small scale, such as transport and heating, through to large plants decarbonising gas-fired power stations and for hydrogen blending in the grid. Furthermore, the funding will accelerate HiiROC’s technical development, broadening its application into areas such as low carbon synthetic fuels and mitigating gas flaring/venting to help meet global methane emission reduction goals announced at COP26.

The funding, adding to existing investment from Wintershall Dea and VNG, will expand the deployment of pilot units into more customer segments, positioning the technology for future roll-out.
