In a monumental bid to turn the long-standing dream of harnessing nuclear fusion into a reality, the US Department of Energy has unveiled an ambitious US$46 million investment strategy. This decisive funding injection will fuel the innovative endeavors of eight nuclear fusion companies, propelling them towards the realization of a nuclear fusion demonstration power plant within the next decade.
As it stands, our current nuclear power paradigm is built around nuclear fission—a process that breaks down heavier atoms into lighter ones to generate energy. However, the real game-changer lies in nuclear fusion, a process that mimics the energetic heart of stars. This celestial process fuses lighter atoms into heavier ones under extreme temperature and pressure conditions, unleashing vast amounts of energy. The challenge? It requires high heat and pressure, a herculean task that has eluded scientists for decades.
However, where there are challenges, there are also opportunities. The Department of Energy remains undaunted by these technological hurdles. With its funding funneled towards eight standout companies from seven states, these organizations are anticipated to receive the financial propulsion they need within the next 18 months. The finish line? Designing a fully operational fusion experimental power plant in a 5-10 year timeframe.
US Energy Secretary Jennifer Granholm is decidedly optimistic, highlighting the Biden administration’s recognition of the enormous potential that nuclear fusion holds. This stellar energy source could match, if not surpass, the abundant energy of the sun and the stars, thereby paving the way for affordable, large-scale, and reliable clean energy production.
Among the trailblazers chosen for this transformative mission are Commonwealth Fusion Systems, Focused Energy, Princeton Stellarators, Realta Fusion, Tokamak Energy, Type One Energy Group, Xcimer Energy, and Zap Energy. The initial funding injection amounts to US$46 million for the first 18 months, drawn from the fiscal years of 2022 and 2023. This potentially five-year-long journey towards fusion’s future depends on future congressional appropriations.
The magnitude of this mission bears significant pressure for these chosen pioneers, as they navigate a competitive landscape. According to a White House briefing, over 30 nuclear fusion companies currently populate the industry, with most emerging within the last decade. One such company, Helion, has already caught the eye of tech giant Microsoft. Though not on the recipient list for this round of funding, Helion has entered into a clean energy provision agreement with Microsoft, banking on their anticipated nuclear fusion power plant set to go online in 2028.
