Uncovering the technical potential of coal-to-nuclear (C2N) power generation on a global scale

Year: 2025

Type: article

Abstract: Decarbonization urgently calls for a substantial replacement of coal-fired power with carbon-free energy in the global energy landscape. However, the prevailing substitution of coal with variable renewable energy cannot be implemented universally due to possible higher cost and lack of power system flexibility. What is more, well-trained coal-fired power workers and surrounding communities are facing challenges. Therefore, we emphasize the unique value of coal-to-nuclear (C2N) in the energy transition by investigating 9,470 coal-fired power units globally. We identified that 14.3% (i.e., 371.6 GW) of them can be prioritized for C2N. The currently available nuclear technologies are feasible for C2N in three ways. A competitive levelized cost of electricity of US$71.84– US$101.48/MWh could be a strong driver when compared to coal+carbon capture and storage. Overall, C2N offers multifaceted benefits, and it can be a good supplement to the prevailing solar and wind renewables.
