Acceleron Fusion Secures $24M Series A Led by Lowercarbon Capital and Collaborative Fund to Revolutionize Clean Energy with Muon-Catalyzed Fusion
Acceleron Fusion, a pioneer in muon-catalyzed fusion energy, has closed a $24 million Series A funding round. The round was co-led by Lowercarbon Capital and Collaborative Fund. This funding marks a significant step in advancing a breakthrough fusion technology that could redefine the future of clean energy while enhancing energy security and independence.
The funding will fuel Acceleron’s efforts to advance its unique approach to clean, safe, and abundant energy. Traditional fusion machines require extreme temperatures of 100 million degrees Celsius. Acceleron’s technology uses muons—heavy subatomic particles—to achieve fusion reactions at temperatures below 1,000 degrees Celsius. This approach could speed the transition of fusion from the lab to practical, deployable power plants. Muon-catalyzed fusion, first discovered in the 1950s, is a proven and well-understood physical process. In the mid 1980s, several groups worldwide demonstrated more than 100 fusion reactions per muon, raising the possibility that the process could be used to generate energy. However, calculations done at the time concluded that it would take more energy to power the muon source than could be released by the fusion.
Acceleron is developing an intense, high-efficiency muon source to produce beams of muons using significantly less energy than current facilities, and a high-density fusion cell to allow each of these muons to catalyze larger numbers of fusion reactions. The company is building on decades of previous work in muon production and muon-catalyzed fusion by university and national lab researchers – and leveraging recent advances in materials science, computer simulation, and machine learning to develop the technology to the level of efficiency needed for energy production.
