Nuclear fusion is gaining attention as more companies enter the field in pursuit of a clean energy source. An updated map from the Clean Air Task Force (CATF) highlights this surge in activity. Nuclear fusion seeks to mimic the reactions occurring in the Sun, where atomic nuclei combine to produce substantial energy. Successfully controlling this process on Earth could lead to a cleaner energy source, reducing greenhouse gas emissions and radioactive waste associated with current nuclear fission reactors.
Despite the potential, achieving practical nuclear fusion has proven challenging. Researchers have been exploring this concept for almost a century, with a significant advancement occurring in 2022. At the Lawrence Livermore National Laboratory in California, scientists demonstrated a net energy gain from a fusion reaction for the first time. Various projects are currently underway to replicate this milestone, aiming for the eventual creation of functional fusion power plants.
According to CATF, the number of companies pursuing fusion technology has significantly increased, particularly in North America and Europe. The organization compiles data from publicly available sources as well as direct conversations with companies and investors. Their fusion map illustrates the geographic distribution of these efforts, including initiatives supported by government programs.
However, some experts caution that it may take decades for fusion energy to become commercially viable, as substantial engineering hurdles still remain. Patrick White, the group lead for fusion energy and safety regulation, stated that while considerable scientific and engineering work is necessary, companies have outlined a clear path toward commercialization, prompting investment interest.
Recent data from the Fusion Industry Association shows that fifty-three fusion companies have secured approximately $8.9 billion in private funding and $795 million in public funding. This marks a significant increase compared to 2021, when 23 companies reported a combined total of $1.9 billion in funding.
