Oil majors pour billions into nuclear fusion startups

The world's largest oil companies are pouring capital into nuclear fusion, wagering that a technology long dismissed as perpetually decades away is now close enough to commercial reality to justify serious investment. Global private funding for fusion hit a record $4.48 billion in the 12 months leading to July 2026, a 69% increase from the prior year, according to the Fusion Industry Association.reuters+1

Oil Majors Spread Their Bets

Chevron ↘ 0.28%, Shell ↘ 1.73%, Equinor ↘ 1.77%, and Cenovus ↗ 0.88% have each built positions across the fusion landscape, backing competing reactor designs before any has produced commercial electricity. Chevron Technology Ventures has invested in both TAE Technologies and Zap Energy, participating alongside Google Alphabet Inc. ↗ 0.96% in TAE's $150 million funding round in 2025 that brought the startup's total equity above $1.3 billion. Shell Ventures joined Chevron in Zap Energy's $130 million Series D round in 2024, backing a company pursuing sheared-flow stabilization rather than superconducting magnets to confine plasma.finance.yahoo+1

Eni ↘ 0.42% has gone furthest among the oil majors. The Italian energy group said in August it aims to help bring a commercial fusion power plant to Europe by the early 2040s or sooner, describing fusion as its "next refinery," according to a Financial Times report confirmed by Reuters. Eni has committed more than $1 billion to purchase electricity from Commonwealth Fusion Systems' planned 400-MW ARC facility in Virginia and formed a joint venture with the UK Atomic Energy Authority to develop tritium fuel-cycle services for future reactors.reuters+1

Commonwealth Fusion Systems Cements Lead

Commonwealth Fusion Systems raised $1 billion on July 30, bringing its total capital to $4 billion and making it the best-funded private fusion company in the world. The company's CEO, Bob Mumgaard, said CFS expects its demonstration reactor, SPARC, to achieve net energy gain in 2027. Its planned commercial plant in Virginia became the first fusion project to apply for grid interconnection with PJM, and Google has agreed to purchase 200 MW of its output.reuters+3

A Shift From Research to Industry

"Competition is growing in the fusion industry after the technology and expectations had changed significantly in the past 5-6 years," said Francesca Ferrazza, Eni's head of magnetic fusion initiatives, in an interview with the Financial Times. "It was always considered research. Now we are considering it as an industry."finance.yahoo

The coordinated push reflects a broader calculation: as electricity demand rises and carbon constraints tighten, oil companies see fusion as a long-dated hedge worth funding even if commercial returns remain years away. Roughly 71% of fusion companies now expect to deliver power to the grid by the 2030s, according to the FIA survey.linkedin
