Net energy and engineering milestones: where do fusion projects stand?
Grasping Net Energy within Fusion ProcessesNuclear fusion aims to produce more energy from fusion reactions than the energy required to initiate and sustain them. This goal is often described as net energy gain, meaning the fusion output exceeds the input at a defined system boundary. Scientists distinguish between:Scientific breakeven: the fusion plasma yields energy equal to the amount directly injected into it.Engineering breakeven: the full installation, encompassing its power infrastructure and supporting systems, generates surplus electricity.Achieving engineering breakeven stands as the key benchmark for fusion to function as a practical energy source, and advances toward this goal have notably accelerated…
