Microsoft signed a contract with a fusion start-up, Helion, in 2023, purportedly to produce fusion power at scale in 2028. Stick a pin in that.
Meanwhile, other start-ups beginning to attract serious investment as buzz grows around this forever-30-years-away technology.
Fusion energy startup Inertia Enterprises has raised $450 million to start developing a power plant that hinges on building the world’s most powerful lasers.
The Series A funding round was led by Bessemer Venture Partners and includes Threshold Ventures, Long Journey Ventures and GV (formerly Google Ventures). The Livermore, California-based company expects to begin construction in 2030 on a commercial power plant. It also plans to build a facility to make the lasers and a production line to supply millions of tiny pellets made of special materials that they intend to blast to trigger fusion reactions.
The scale of the funding reflects the growing interest in fusion, which holds the promise of abundant clean energy but also comes with daunting engineering and physics challenges. The industry attracted more than $9.7 billion in backing through the middle of last year, according to a Fusion Industry Association report released in July.
Major deals have continued since then, led by an $863 millionfunding round announced by Commonwealth Fusion Systems in August. Dozens of companies are pursuing the technology, which involves replicating the conditions at the heart of stars, but none has yet demonstrated a viable commercial system.
