What is being bought

Published requirement description

Fusion offers potential future energy abundance yet is at the same time highly challenging. In the context of a fusion future full of opportunity, but also complexity, UKAEA wishes to learn more about potential future energy landscapes and ecosystems. In such energy ecosystems, fusion might enter in various ways, perhaps replacing technologies existing at the time (e.g. due to obsolescence/end of life), perhaps augmenting other technologies to address the increasing demand or aiming at affordable solutions for specific supply needs and characteristics not readily met by other technologies. In particular, uses of fusion might expand beyond grid electricity. UKAEA is interested to see what potential characteristics of fusion plants might help or hinder fusion deployment, as this can inform UKAEA’s future strategy.
