The Fusion Industry Association (FIA) has called for an increased budget for fusion in 2028 in the US and more transparency over the strategy for fusion energy in Europe in two separate letters sent to the US Department of Energy (DOE) and the European Commission.

In its letter to the DOE, the FIA said the DOE must fund its fusion programme at the top end of its authorised $1.114bn (€950m) budget and keep the US on target to meet its objective of demonstrating commercial fusion power in the US by the mid-2030s.

The FIA also made a list of recommendations to the DOE to help the US build support for private-public partnerships, research infrastructure and commercial demonstration.
