Activity: Participation in Academic conference (Speaker) - Nuclear Institute Webinar
Many industries will be able to decarbonise through electrification, and nuclear power has an important role to play here as a proven source of abundant low carbon electricity. Electrification however is not a universal solution however, and there are significant sectors of the economy that currently have no clear route to achieving net-zero. Nuclear can produce more than electricity and by creatively coupling nuclear technology to industrial processes there is the real prospect of providing the technical solutions required to enable the type of deep decarbonisation required by current climate goals.
