About
Kyoto Fusioneering is a Japanese fusion energy engineering company focused on developing and commercializing the reactor components and subsystems required to build practical fusion power plants. Founded in 2019 as a spin-off from Kyoto University and headquartered in Kyoto, Japan, the company does not aim to build a complete fusion reactor itself but rather specializes in the balance-of-plant technology — the ancillary systems that make a fusion plant function, including tritium fuel cycle systems, breeding blankets for tritium production, and plasma-facing components.
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.
