Kyoto Fusioneering starts work on key fusion power plant device
In the fusion power world, most of the attention gets lavished on the reactors themselves, where atoms fuse to unleash enormous amounts of energy. But a fusion reactor can’t run for long without a lot of other equipment, and building a fusion reactor is expensive enough on its own. Plenty of startups are happy to let someone else handle the rest.

Opening excerpt (first ~120 words) tap to expand
In the fusion power world, most of the attention gets lavished on the reactors themselves, where atoms fuse to unleash enormous amounts of energy. But a fusion reactor can’t run for long without a lot of other equipment, and building a fusion reactor is expensive enough on its own. Plenty of startups are happy to let someone else handle the rest. Among the dozens of companies in the emerging fusion power supply chain, few specialists are bigger than Kyoto Fusioneering. The Japan-based company has raised $121 million in committed capital, according to FusionX. Now it has landed grants from the U.S. Department of Energy and the state of Tennessee to build a prototype fuel breeding device at Oak Ridge National Laboratory (ORNL).
