Nuclear power plants all operate using nuclear fission, but one energy startup has plans to change this. Commonwealth Fusion Systems (CFS) has announced plans to build the world's first nuclear fusion power plant.
Set to be located in Chesterfield County, Virginia, the plant will infuse "400 megawatts of steady fusion power into the state's electrical grid starting in the early 2030s," CFS said in a press release. Unlike nuclear fission, which splits atoms to create energy, nuclear fusion generates power by combining atoms. It's the process that powers the sun. Power plants have never used this process because it's extremely difficult, requiring temperatures over 180 million degrees Fahrenheit and immense amounts of pressure and energy.
'Long-elusive goal' Creating a fusion-based power plant is a "long-elusive goal that scientists have pursued for the better part of a century," said The New York Times. If successful, CFS' plant could "generate abundant electricity without releasing planet-warming carbon dioxide and with no risk of large-scale nuclear accidents," providing a much sought-after alternative to current nuclear power plants.
Many recent advances have created "hope that the technology could be achievable in the next few years," said The Washington Post. CFS estimates it could power about 150,000 homes. Scientists "need to start fitting fusion energy into our code where necessary, because fusion energy for years has been theoretical,” said Richard C. Sullivan Jr., a Democrat in the Virginia House of Delegates.
'Failed promises' Despite the optimism from CFS, many "failed promises litter the path to workable fusion," said Scientific American. So we should "hold our nuclear horses for just a moment." Given its difficulties, fusion is the "kind of technology that always seems to be just 15 years away."
While the ultimate goal of the project is to prove that fusion reactors can be commercialized, the "path toward it is unlikely to be smooth, not least because the technology has not yet been proved viable," said at CNN. There's a "big difference between producing energy from fusion," said Jerry Navratil, a professor of fusion energy and plasma physics at Columbia University, to CNN, "and having a practical system that puts power on the grid and is safe, licensed and operating." |
