Powering the Future: How Close Are We to Fusion Energy?

This week, Brian Appelbe, Research Fellow at the Centre for Inertial Fusion Studies (CIFS) at Imperial College London, who specializes in Inertial Confinement Fusion (ICF) and High Energy Density Physics, joins the podcast.

Fusion energy aims to create a miniature sun on Earth, utilizing the same process that powers the sun, where tiny atoms fuse together to release a massive amount of clean energy. Recent breakthroughs in fusion include experiments achieving net energy gain and private developers pledging to have grid-connected fusion electricity generation units by the mid-2030s.

Here are some questions Peter and Jackie asked Brian: What are the advantages of fusion energy? How does it differ from nuclear fission? Realistically, how long before fusion is a commercial reality delivering electrons to the grid? How has the entrance of private companies and almost $7 billion in total private investment changed the pace of innovation? Do you think fusion energy will eventually be low-cost, and if so, what are the potential new uses of this abundant and cheap form of electricity?
