Nuclear fusion is seen as a hope in the fight against the climate crisis. To generate energy using nuclear fusion, reactors must maintain extremely high temperatures.

Researchers from South Korea are now reporting success. But they are still a long way from their actual goal of creating a fusion power plant that can generate enough electricity to supply households and industries. The ultimate goal of KSTAR is to achieve 300 seconds of plasma operation with ion temperatures of over 100 million degrees, says a statement. The team achieved a record - but their work is far from over.
