TerraPower is developing compact modular nuclear reactors with a closed fuel cycle. Its goal is to make nuclear energy safer and cheaper, while also minimizing radioactive waste. It was co-founded by Bill Gates and partners with GE Hitachi Nuclear Energy. Its sodium-cooled fast reactor, Natrium has capacity up to 345 MW, has a molten salt heat storage system and uses innovative liquid metal cooling. Its advantage is its flexible power output, allowing it to respond to fluctuating demand when combined with renewable energy sources. It uses liquid sodium as a coolant and highly enriched uranium (HALEU) as fuel (although the company is experiencing supply issues). The demonstration reactor project is expected to be operational by 2030.

Helion Energy uses fusion energy to provide pure, safe electricity. Helion's fusion generator elevates fusion (Deuterium and helium-3) fuel to ultra-high temperatures to achieve plasma conditions and directly obtains electricity with a high-efficiency pulsed approach. Magnets confine the plasma in a Field Reversed Configuration (FRC) and speed up two FRCs to 1 million mph from opposite ends of the generator. When the FRCs collide in the center of the system, they are further compressed by a strong magnetic field until they reach fusion temperatures greater than 100M degrees Celsius (150M already achieved). At this temperature, the deuterium and helium-3 ions are moving fast enough to surpass the forces that would otherwise keep them apart, and they fuse. This emits more energy than is consumed by the fusion process. As new fusion energy is generated, the plasma enlarges.

EPYR creates industrial power systems that convert electricity from renewable energy sources into high-temperature heat. These are comprehensive solutions integrate equipment, intelligent energy management and financing. The Epyr system captures electricity from the grid at its lowest cost and converts it into heat using resistive heaters. Thermal energy is stored in high-efficiency refractory bricks and released as air or steam on demand for industrial processes. Thanks to fast and precise control, the system is easily integrated into production processes. Epyr also offers a "heat-as-a-service" model that requires no upfront capital investment - the company builds, owns and operates the system for an annual fee.

SaltX Technology has developed an electric CO2 separation technology for direct CO2 capture from air in high-temperature industries, including quicklime and cement production. This electric calcination technology uses electric plasma to replace fossil-driven heating with renewable electricity. The mineral solution used in direct carbon dioxide capture (DAC) is carbonated after binding with CO2 from the air. This carbonate solution can be regenerated during the electric calcination process, separating and isolating the CO2 for further use or geological storage. The EAC (electric arc calciner) is adaptable to various industries. Through seamless integration into DAC systems it makes the release and collection of pure CO2 more efficient. The company has already launched a 1.4 MW pilot plant producing 17 tons of carbon per day.

Found Energy is developing aluminum-based fuel for industrial applications. Found Energy's thermal energy technology converts any aluminum into an energy-dense fuel by breaking down the oxide layer, allowing the aluminum to rapidly and completely oxidize upon contact with water in a process called fractal exfoliation. This highly exothermic process releases the energy stored in the aluminum as a combination of heat and hydrogen (or superheated steam). The system generates superheated steam at the highest temperatures required by modern industry. Aluminum fuel can be used to produce hydrogen on-site, on-demand (meaning aluminum fuel is cheaper and safer to transport than hydrogen).

Pacific Fusion is developing a high-gain pulsed magnetic fusion system. Pulsed magnetic fusion involves rapidly compressing a fuel in a container with a powerful magnetic field created by passing high, rapidly increasing electric current through it. This compression heats and inertially holds the fuel, converting hydrogen into helium and releasing massive amounts of energy. The company has eliminated the magnetic system to simplify the system and its maintenance requirements. The system is highly modular, enabling affordable manufacturing and rapid iteration. It uses commonly available materials, simplifying supply chains. The modular pulser can be optimized for a wide range of target designs.
