11
PeroCycle
Funding: £4M
PeroCycle provides a closed-loop carbon recycling system for steelmaking. It utilizes gases from blast furnaces, basic oxygen furnaces or direct reduced iron plants and utilizes industrial gas separation technology to produce a highly concentrated CO2 stream, which is then processed in a thermochemical reactor. The reactor operates at approximately 800°C and, using a proprietary active material, converts CO2 into CO for injection as a reducing agent into the blast furnace. This creates a sustainable carbon cycle that, when fully implemented, can reduce carbon emissions at a steel plant by up to 90%. The technology easily integrates with existing steelmaking systems, eliminating the need for new plants or significant infrastructure changes.
