Blue Energy – An innovative, early-stage, Massachusetts-based nuclear plant designer and integrator, working to develop a novel, off-shore methodology to deploy licensed small modular light water reactors (SMRs) at scale using monopiles and other mature, off-the-shelf wind turbine deployment techniques.
SHINE Technologies – A Wisconsin-based developer of fusion energy, commercializing in the interim their high flux neutrons from DT fusion for radiation effects testing, isotope production and waste separation enroute to development of cost-effective fusion energy, producing Ilumira, a potent cancer therapy, made from Lutetium-177.
Zeno Power – A venture harnessing the radioisotope decay from nuclear waste such as Strontium-90 to generate electron flow for years of reliable energy for frontier applications from deep sea to deep space.
Aalo Atomics – Leveraging their experience designing the DOE’s Gen IV microreactor, MARVEL, an advanced nuclear reactor developed at the INL, to expedite the design, review, approval and scaled deployment of a fleet of highly stable and safe commercial sodium-cooled microreactors optimized for use by data centers and others.
Twelve (Q1-24) – A Berkeley, California-based developer and producer of sustainable aviation fuel (SAF) and naphtha using a “power-to-liquid” approach to reducing carbon by 90%.
NuclearN – A Phoenix, Arizona-based developer of nuclear AI support modules and services, which are already in use by a majority of North American nuclear power plant operators, working to enable maximum efficiency and efficacy of operational budgets.
Blykalla (formerly LeadCold) – The Swedish developer of the high-temperature, low-cost, lead-cooled reactor called the Swedish Advanced Lead Reactor (SEALER) and currently the only Swedish advanced nuclear developer in a country looking to add more nuclear power.
Planetary Technologies – A Canadian-based developer of an Ocean Alkaline Enhancement (OAE) approach to marine carbon dioxide removal (mCDR) which leverages the water cooling systems of existing nuclear power plants or waste treatment plant effluents to effect distribution of their "antacide" and maximize decarbonization of seawater and climate restoration.
Copenhagen Atomics – A Danish developer of a thorium molten salt thermal breeder reactor—which turns nuclear waste into fuel—is looking to mass manufacture thorium-powered reactors at an exceptionally low price.
