About HiiROC

HiiROC is a UK-based technology company founded in 2019 that specializes in producing low-cost, zero-emission clean hydrogen through its proprietary Thermal Plasma Electrolysis (TPE) process.

This innovative method converts various gas feedstocks, including natural gas and biomethane, into hydrogen and solid carbon black without releasing CO2, using significantly less energy than traditional methods. The company offers modular and scalable clean hydrogen production systems designed for on-site generation, which can help clients reduce capital and operational costs. HiiROC also produces carbon black, a valuable by-product with applications in industries such as construction, manufacturing, and agriculture. With a focus on supporting the transition to a carbon-neutral energy landscape, HiiROC serves various sectors, including construction, energy, transportation, and aerospace, and has established partnerships with notable companies like Cemex and Siemens.
