The US Department of Energy (DOE), last week, announced the winners of $32 million in funding for 15 nuclear fusion research projects.

The funding award was part of the Breakthroughs Enabling THermonuclear-fusion Energy (BETHE) programme.

The BETHE projects will work to develop timely, commercially viable fusion energy, with the goal of increasing 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 DOE 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.”

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, DOE said.

If a grid-ready fusion demonstration can be realised within around 20 years, while achieving cost competitiveness, then fusion could contribute to meeting low-carbon energy demand and achieving decarbonisation in the latter half of this century, DOE added.

"BETHE projects address these needs by building on Advanced Research Projects Agency–Energy’s (ARPA-E) first focused fusion programme, ALPHA, to grow the number of privately funded fusion companies," it said.

“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.

BETHE projects span 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 to accelerate the development of multiple concepts.
