H2 Green Steel is building a steel production plant (in Boden, northern Sweden) that reduces the iron ore into green iron using 100% green hydrogen with near-zero emission. The heart of the plant is giga-scale electrolyzer, powered by renewable electricity (instead of coal) that splits water into its constituent parts: hydrogen and oxygen. Then in the reduction reactor the hydrogen reacts with oxygen in the iron ore, transforming the iron ore into sponge iron and producing (environmentally friendly) water steam. In the melt shop the iron is charged into an electric arc furnace, where it is mixed with steel scrap. It is then melted with a powerful electrode and alloys are added in a ladle furnace. The molten steel is transformed into solid products.

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.

HyperHeat is developing the HyperHeat system, which utilizes renewable energy sources for high-temperature heating required in heavy industries such as steel production, cement and chemical processing. HyperHeat system is based on a low-cost industrial gas heater that utilizes oxide ceramics for ultra-high-temperature resistive heating. It can be installed in existing furnaces (instead of fossil-fuel burners) and achieve temperatures close to flame temperature - up to 2000°C. HyperHeat systems connect directly to standard industrial medium-voltage networks, scaling from hundreds of kilowatts to several megawatts, ensuring easy integration and maximum efficiency.
