At the upcoming UN climate summit in Dubai, US Special Envoy on Climate Change John Kerry is expected to propose the first international strategy to commercialize nuclear fusion power on Monday, according to two people who are aware of the development.

Due to its ability to produce radioactive waste that is not permanent, fusion power plants have significant advantages over current nuclear fission reactors that divide atoms. It might also offer an inexpensive source of carbon-free electricity if it is implemented well.

The former secretary of state will announce his plan to lay out the strategy that foresees strengthened cooperation with other countries aiming to speed commercialization on a tour of fusion company Commonwealth Fusion Systems near Boston.

The UK and the United States on Nov. 8 signed a cooperation agreement on fusion.

Fusion, the process that powers the sun and stars to generate electricity, can be replicated on Earth with heat and pressure using lasers or magnets to smash two light atoms into a denser one, releasing large amounts of energy.

Eni is working on four fusion research partnerships in Italy and the US, including one with Commonwealth.

“I will have much more to say on the United States’ vision for international partnerships for an inclusive fusion energy future at COP28,” Kerry said in a statement.

Decades of federal investment is transforming fusion from an experiment to “an emerging climate solution”, he added.
