The European Commission, Directorate-General for Energy, has published the "Foresight study on the worldwide developments in advancing fusion energy, including the small scale private initiatives."
Commissioned from the consultancy Trinomics, the paper provides an analysis of the leading public and private fusion initiatives globally and uses the analysis to generate four foresight scenarios for fusion development to inform European Commission decision making on fusion.
What are the strengths and weaknesses of various fusion approaches? When can the next fusion devices be expected? What are the most optimistic and least optimistic estimations for the arrival of fusion power on the grid? What technical challenges remain?
