2022 was a significant year for nuclear fusion, touted as a future solution to our energy problems. First came the announcement, in February, that a record for power generation that has stood for 24 years had been surpassed. Then, in December, for the first time ever, more energy was output from a fusion reaction than was put in (with the caveat that accounting for the full energy costs of the process still led to more energy being used than was produced).
In the latest edition of Periodic Graphics in Chemical & Engineering News, we look at fusion reactors and their history. View the full graphic on the C&EN site here.
