Brillouin Energy
Brillouin Energy is an Emeryville, California clean-technology company developing thermal energy systems based on Low Energy Nuclear Reactions (LENR). Its patented Controlled Electron Capture Reaction (CECR) process uses small amounts of hydrogen, nickel and electricity to generate heat via its Hydrogen Hot Tube (HHT) reactor and proprietary Q-Pulse control system, with helium as a negligible byproduct and no carbon emissions or radioactive waste. Founded in 2009 by Robert Godes, the company aims to commercialize licensable, ultra-clean heat for industrial process, district energy and distributed power applications.
Addis Energy
Addis Energy is a Somerville, Massachusetts climate-tech company turning the Earth's subsurface into a chemical reactor to make ammonia. By injecting nitrate-bearing water into iron-rich underground rock, its process uses natural heat and pressure to convert nitrogen into ammonia without hydrogen feedstock, added electricity, or CO2 emissions. Spun out of MIT research and paired with deep oil-and-gas engineering experience, the company aims to produce clean ammonia - a fertilizer and potential fuel behind more than 1% of global emissions - at a fraction of conventional cost.
Pasteur Labs & ISI
Pasteur Labs & ISI is a New York-based public-benefit deep-tech company building 'Simulation Intelligence' - the systematic merger of AI, physics simulation, and scientific computing. Its AI-native, GPU-accelerated, end-to-end differentiable physics platform gives engineers and scientists an in-silico playground to run thousands of what-if scenarios and shrink the gap between digital models and physical reality. Founded in 2021 by AI researcher Alexander Lavin and staffed by veterans of DeepMind, NASA, CERN, Tesla, Nvidia and Ansys, the company targets industrial R&D, energy, climate, and space & defense, and stewards the open-source Tesseract framework for differentiable scientific computing.
The Nuclear Company
The Nuclear Company is a U.S. nuclear infrastructure platform building a standardized fleet of large reactors using proven, already-licensed designs. Rather than inventing new reactor technology, it applies a 'design-once, build-many' methodology layered with AI and digital-twin software to cut the cost and timeline of building gigawatt-scale nuclear power. Founded in 2023 by Jonathan Webb, Kiran Bhatraju, and Patrick Maloney, it has raised about $70M to evaluate sites for an initial 6-gigawatt fleet targeted for the early 2030s.
