Key indicatorsIndustry: Nuclear powerNuclear power Founded: 20162016 Headquarters: Alameda, California, USAAlameda, California, USA Notable fact: In 1954, Oak Ridge National Laboratory in the US was home to the first molten salt reactor, an experimental power source for a possible supersonic nuclear aircraft. Potential for impactWith sharp cuts to US federal funding for solar and wind projects, nuclear power is one of the few zero-carbon technologies that still attract bipartisan political support. Although developing new systems is slow and expensive, nuclear reactors excel at providing 24/7 baseload power that can replace fossil fuel plants. Small modular reactors like the ones Kairos is building are particularly attractive for places that require steady amounts of power or lack reliable transmission infrastructure. CaveatsAlthough there have been numerous experimental molten salt reactors, no one has yet shown that they can operate one consistently and profitably over the long term.
