Seattle-area fusion company Helion Energy is reportedly negotiating a deal to supply OpenAI with significant amounts of energy. The deal would reportedly involve 5 gigawatts of power by 2030, rising to 50 gigawatts by 2035. Helion has yet to prove its electricity-generating technology is commercially viable. The company, which has raised over $1 billion from investors including Sam Altman, CEO of OpenAI, is currently operating its seventh-generation prototype in Everett, Wash. The first commercial facility for the OpenAI deal is expected to begin by 2028.
