MIT researchers publish economic framework for fusion profitability

Researchers at the Massachusetts Institute of Technology (MIT) have published a new economic evaluation framework designed to determine the costs required for nuclear fusion plants to achieve commercial profitability. The study, published in The Journal of Fusion Energy, aims to provide a guide for investors and developers by establishing target costs for sustainable development.

Lead researcher Dennis Whyte and co-author Andrew W. Lo emphasized that scientific success in laboratory settings does not automatically translate to commercial viability in competitive energy markets. The new model is technology-neutral and evaluates ten key parameters, combining engineering variables such as power density, energy conversion efficiency, and component durability. This approach is inspired by the Lawson Criterion, which measures the ratio of plasma energy generated to external energy required.

While recent breakthroughs, such as the 2022 net energy gain at Lawrence Livermore National Laboratory, have increased funding for fusion startups, researchers warn that future facilities must generate sufficient revenue to cover both construction and operating costs to be viable.
