The US Department of Energy has announced the winners of $32m in funding for 15 projects as part of the Breakthroughs Enabling THermonuclear-fusion Energy (BETHE) program.

These projects will work to develop timely, commercially viable fusion energy, with the goal to increase the number and performance levels of lower-cost fusion concepts.

“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 Under Secretary 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.”

“These BETHE projects further advance ARPA-E’s commitment to the development of fusion energy as a cost-competitive, viable, energy generation source,” said ARPA-E Director Lane Genatowski. “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.”

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. BETHE projects will address one of these categories.

Commercial fusion technology has long been viewed as an ideal energy source. However, there remains a need to lower the costs of fusion development and accelerate its development timeline to have appreciable impact.

If a grid-ready fusion demonstration can be realized within approximately 20 years, while achieving cost competitiveness, then fusion can contribute to meeting low-carbon energy demand and achieving cost-effective deep decarbonization in the latter half of the 21st century.

BETHE projects address these needs by building on Advanced Research Projects Agency”Energy’s (ARPA-E) first focused fusion program, ALPHA, to grow 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.
