This data-file screens 15 companies at the cutting edge of nuclear technology, to assess whether fission or fusion breakthroughs can realistically be factored into long-run forecasts of energy markets or the energy transition.
Our conclusion is “not yet”. Despite many signs of exciting progress, the average technical readiness in our sample is TRL 4 (testing components). Four companies are working to lab-scale prototypes. Energy gains and system stability remain key challenges.
The database summarises each company, including its technology, location, employee count, notable backers and technical technical readiness. Our notes also cover expected costs or timings, where disclosed.
