Fusion power in a future low carbon global electricity system

Abstract Fusion is one of the technologies that may contribute to a future, low carbon, global energy supply system. In this article we investigate the role that it may play under different scenarios. The global energy model ETM (originally EFDA TIMES Model) has been used to analyse the participation of fusion technologies in the global electricity system in the long term. Results show that fusion technologies penetration is higher in scenarios with stricter CO 2 emissions reduction targets. In addition, investment costs and discount rates of fusion technologies are key factors for fusion implementation. Finally, the main competitors for fusion in future are Carbon Capture and Storage and fission technologies.
