Investments in fusion technology have jumped by $2.6 billion in the year to July, the most since 2022, the Fusion Industry Association said in a new report on Tuesday, noting that the growth in funding for fusion energy companies “is the most striking indicator of the industry’s accelerating trajectory.”
The association’s report showed that total funding for fusion efforts has exceeded $9.7 billion since 2021, with more than $2.6 billion raised in the last year alone.
The surge in investments is a signal of “maturing investor confidence, technological progress, and a rapidly coalescing supply chain,” Andrew Holland, CEO at the Fusion Industry Association, wrote in the foreword to the report.
“This is despite the fact that most of the last half-decade have not been banner years for broader investment in technology fields – affirming fusion’s unique appeal as a secure, scalable, and clean energy solution to the world’s power needs.”
Fusion is the natural process that heats the Sun and all other stars, in which a huge amount of energy is produced by the fusion of light atoms, such as those in hydrogen, into heavier elements like helium.
Nuclear fusion has long been considered the answer to zero-emission by-product-free energy generation. However, no one has cracked the nuclear fusion code yet because of the challenges associated with the environment in which the process could take place.
The 53 firms surveyed in the 2025 report note that access to funding remains a major issue for fusion companies, highlighting the long development timelines and capital intensity of the industry. Across the board, the responses noted that while fusion’s promise is within reach, sustained progress will require continued technological breakthroughs and financial, regulatory, and policy support, the association said.
Public funding has surged by 84% in one year, suggesting that governments have started to recognize the promise of fusion energy, the industry body added.
