Antares designs and builds microfission reactors for strategic energy applications, including space missions, commercial and military energy resilience. The R1 microreactor can produce from 100 kilowatts to 1 megawatt and uses TRISO fuel, which consists of uranium spheres coated with carbon and ceramics, embedded in graphite. The company performs high-precision machining of the nuclear graphite in-house, speeding design iterations. The optimized reactor design simplifies deployment with a minimal number of actuators. The control drums, made of graphite and boron carbide, have independent actuators, inspired by the designs of historical space reactors. Antares has a manufacturing facility in California and has already tested the first electrically heated demonstration unit (EDU).

Thea Energy is developing pixel-inspired Helios fusion reactor that will offer a lower cost than competitors. It's a stellarator - a special type of reactor that uses magnets to shape plasma fuel into the desired shape. These magnets are small, identical superconducting magnets, allowing for mass production. The startup will use software to individually control each magnet to generate magnetic fields that can replicate the stellarator's unstable shape. This approach allows rapid optimization of the magnet design. Helios is projected to generate 390 megawatts of electricity at a cost of under $150 per megawatt-hour. Production is scheduled to start around 2030.

Critical Energy is an energy based firm that generate electricity with the help of heat through modular and geothermal power plant. Its bet is less about drilling deeper than about building the bit above the ground faster. The startup treats a power plant as a product, not a construction project. Critical Energy’s units are container-sized turbines built mostly off-site, designed to be trucked in and switched on in weeks, then stacked together for larger sites. Critical Energy has a pilot in Los Angeles and its first commercial 2.5mn-watt project is due for completion in 2027.

Gridcog provides energy system modeling and optimization software that helps developers, investors, utilities, and energy companies evaluate and optimize renewable energy, battery storage, electrification, and hybrid energy projects. It allows to simulate standalone projects or hybrid and multi-asset developments with shared constraints, simulate how assets actually dispatch and earn revenue under real market conditions, understand how real-world grid constraints impact dispatch, curtailment, how battery design and operating assumptions affect long-term value.

Enerkem has developed gasification technology that converts a wide range of biomass waste into low-carbon fuels and chemicals. Shredded waste is fed into a bubbling fluidized bed gasification reactor where it reacts with steam and oxygen, breaking down the molecules and producing a gas mixture called syngas. The syngas is then sent to another vessel, a reformer, for further conversion of the molecules into the desired components. The resulting syngas is rich in hydrogen and carbon monoxide, key building blocks of molecules used in modern chemical processes. Enerkem has a pipeline of new projects to produce 1,000,000 tons of environmentally friendly methanol per year.
