The winners of $32 million in funding for 15 projects to develop timely, commercially viable fusion energy were announced by the Department of Energy in April. As part of the DOE Advanced Research Projects Agency–Energy’s (ARPA-E) Breakthroughs Enabling THermonuclear-fusion Energy (BETHE) program, the projects will work to increase the number and performance levels of lower-cost fusion concepts.
What they’re saying: “Fusion energy technology holds great potential to be a safe, clean, reliable energy source, but research and development of fusion technology is often constrained by prohibitive costs,” said Undersecretary of Energy Mark W. Menezes. “BETHE teams will build on recent progress in fusion research and the growing fusion community to lower costs and further foster viable commercial opportunities for the next generation of fusion technology.”
ARPA-E Director Lane Genatowski added, “These BETHE projects further advance ARPA-E’s commitment to the development of fusion energy as a cost-competitive, viable energy generation source. Commercially viable fusion energy can improve our chances of meeting global energy demand and will further establish U.S. technological lead in this crucial area.”
The projects: BETHE projects will work to deliver higher-maturity, lower-cost fusion options via three research categories: (1) concept development to advance the performance of inherently lower-cost but less-mature fusion concepts; (2) component technology development that could significantly reduce the capital cost of higher-cost, more-mature fusion concepts; and (3) capability teams to improve/adapt and apply existing capabilities (including theory/modeling, machine learning, and diagnostics) to accelerate the development of multiple concepts. Each BETHE project will address one of these categories.
According to the DOE, the BETHE projects build on ARPA-E’s first focused fusion program, ALPHA, to increase the number of privately funded fusion companies. BETHE teams will pursue additional approaches that reduce cost, unit size, and complexity of fusion systems while also smoothing the path to fusion commercialization to include public, private, and philanthropic partnerships with the BETHE teams.
