Tokamak Energy vs Electric Hydrogen
Side-by-side comparison of AI visibility scores, market position, and capabilities
Tokamak Energy is Europe's best-funded fusion startup targeting commercial fusion by the 2030s; raised $335M total including $75M in 2025, partnered with US DOE on $52M ST40 upgrade.
About
Tokamak Energy is a UK-based private fusion energy company developing compact spherical tokamak reactors and high-temperature superconducting (HTS) magnet technology as a faster, lower-cost path to commercial fusion power. Its approach uses a spherical tokamak geometry — a more compact, donut-shaped design compared to conventional tokamaks — combined with proprietary HTS magnets that enable higher magnetic field strengths at lower cost, which the company believes will accelerate the timeline to net energy gain and commercial viability. Tokamak Energy aims to deliver first fusion power to the grid by the early 2030s.
Electric Hydrogen designs and manufactures 100MW+ industrial electrolyzer systems for green hydrogen production at scale; raised $380M in funding including a $200M Series C in 2023;
About
Electric Hydrogen is a Natick, Massachusetts-based clean energy company founded in 2020 by Raffi Garabedian (former CEO of First Solar) and David Eaglesham. The company designs and manufactures large-scale industrial electrolyzers — systems that use electricity to split water into hydrogen and oxygen — intended to produce green hydrogen at the cost and scale required to decarbonize heavy industries. Electric Hydrogen's core product is a 100MW electrolyzer plant that represents one of the largest single electrolyzer systems commercially available, designed for industrial customers in steel, ammonia, chemicals, and fuel production who need hydrogen at massive volumes.
