AMPERA develops next-generation subcritical thorium-based microreactor systems for AI data centers, that are energy dense and do not require refueling. Its nuclear module is designed to provide decades of reliable carbon-free power with exceptional energy density, safety, and longevity. The company also plans to process the raw thorium in-house at its facility in Florida and to use its proprietary jetting technology to manufacture high-quality Tri-structural Isotropic (TRISO) fuel kernels.

Mazama Energy is a geothermal startup targeting deeper and hotter rock. It has drilled past 10,000 feet in 15 days on its way to about 15,000 feet deep. At those depths, the company can access 400˚C heat, which at high pressures turns water into a “supercritical” fluid that’s neither fully liquid nor fully gas — a state that lets it absorb far more energy than ordinary steam. Mazama says that will allow each well to produce up to 10 times more power than traditional geothermal technologies. Company's first site in Oregon is capable of producing 10 gigawatts of electricity.

Quaise Energy is a geothermal startup that has developed technology for drilling ultra-hot rock. It aims to reduce geothermal energy costs by using a proprietary millimeter-wave drilling technology to produce more energy with fewer boreholes, drilling deeper into hotter rock. At greater depths, Quaise will replace the drill bit with an energy beam, essentially using microwaves to vaporize the rock. This process is intended to reduce downtime and replacement costs, making geothermal energy a more competitive energy source. To reach desired temperatures of 300-500C, Quaise will have to drill deeper than other enhanced geothermal systems.

Fuse intends to build a MagLIF (Magnetized Liner Inertial Fusion) reactor in which energy is delivered to the fuel by an impedance-matched Marx generator. This device first charges a multitude of capacitors in parallel—relatively slowly—and then connects them very rapidly to produce a short, high-voltage pulse of immense power.

SunUp Fusion is constructing its first-generation experimental device, compact high-field tokamak codenamed "Morning Light". The startup is pursuing a differentiated technological path centered on a Deuterium-Helium-3 (D-He3) fuel cycle. Its compact D-He3 power plants are designed for flexible deployment near urban centers or data hubs. This strategy would allow them to work in tandem with larger, remote D-T facilities to form an integrated and versatile energy grid.
