• The U.S. will lay out the first international strategy to commercialize nuclear fusion power at the upcoming UN climate summit in Dubai, U.S. Special Envoy on Climate Change John Kerry will say on Monday, two sources familiar with the announcement said.
• Fusion could have an important advantage over today’s nuclear fission plants that split atoms, as it does not produce long-lasting radioactive waste. If deployed successfully, it could also provide a cheap source of carbon-free electricity.
• But there are hurdles to fusion’s producing commercial electricity. The energy output of last year’s fusion experiment at the U.S. National Ignition Facility was only about 0.5% of the energy that went into firing up the lasers, some scientists estimate.
