Nuclear fusion melds two hydrogen atoms together to produce a helium atom and a lot of energy—which could be used to power cars, heat and cool homes and other things that currently are often powered by fossil fuels like coal, oil and gas. That makes fusion a potentially major solution to climate change, which is caused by the burning of fossil fuels. Still, fusion is a long way off, while other clean technologies like wind, solar and others are currently in use and could be increased.
“We are edging ever-closer to a fusion-powered reality. And at the same time, yes, significant scientific and engineering challenges exist,” Kerry said, in Dubai for U.N. climate talks. “Careful thought and thoughtful policy is going to be critical to navigate this.”
Researchers have been trying for decades to harness the reaction that powers the sun and other stars — an elusive goal because it requires such high temperatures and pressures that it easily fizzles out.
Kerry wants to speed that up in hopes of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, a benchmark set by the international community. He urged nations to come together to “harness the power of fundamental physics and human ingenuity in response to a crisis.” The strategy lays out five areas for international partnerships: research, the supply chain and future marketplace, regulation, workforce issues and public engagement. Kerry spoke at the Atlantic Council Global Energy Forum.
