World’s leading steelmaker ArcelorMittal has invested USD 25 million in nuclear innovation company TerraPower through its XCarb Innovation Fund. The investment is part of an USD 830 million equity raise TerraPower has concluded, which is the largest private raise among advanced nuclear companies. TerraPower, which was founded by Mr Bill Gates in 2008, entered the nuclear energy arena because the company’s founders saw clean energy as the pathway to lift billions out of poverty. It has spent the last decade investing in and developing ground-breaking nuclear technologies. Its flagship technology is Natrium, which features a cost-competitive sodium fast reactor combined with a molten salt energy storage system. This combination will provide clean, flexible energy and integrate seamlessly into power grids with high penetrations of renewables. TerraPower is experiencing significant growth, and is currently building its first Natrium reactor, a TerraPower and GE Hitachi technology, as part of the U.S. Department of Energy’s Advanced Reactor Demonstration Program. The facility, being constructed near the site of a retiring coal plant in Kemmerer, Wyoming, will feature a 345 MWe sodium fast reactor alongside an energy storage system that can boost output to 500 MWe during peak demand. Large scale, first-of-a-kind, energy generation projects like the Natrium™ project take years to come to fruition, and TerraPower is targeting an in-service date for the project within this decade. ArcelorMittal’s XCarb Innovation Fund was launched in March 2021. The fund’s purpose is to supplement the Company’s own extensive Decarbonisation technology development programme, by investing in early stage, breakthrough technologies which hold strong potential to contribute to the Decarbonisation of steelmaking. The fund targets investing in seven technology domains, namely:Disruption in steelmakingWaste to gas or biocarbonGas reforming/gas transformation technologiesDisruptive hydrogen technologiesCarbon capture, utilization and storageLong-duration, large-scale energy storage technologiesClean energy technologies Since launch, the fund has made investments of USD 122.5 million in five companies – Heliogen, Form Energy, LanzaTech, H2Pro and TerraPower. In September 2021, the Company also committed to an equity investment of USD 100 million over a five-year period when it became an anchor partner in Breakthrough Energy’s Catalyst Program. Breakthrough Energy was founded by Bill Gates and its Catalyst program combines public and private finance to accelerate the development and deployment of four Decarbonisation technologies: direct air capture; green hydrogen; long-duration energy storage and sustainable aviation fuel. It recently announced its first project funding, with USD 50 million granted to LanzaJet’s Freedom Pines Fuels sustainable aviation fuel plant in Soperton, Georgia.
