Nuclear fusion: Tomorrow's solution to today's problem​

August 18, 2026 · 12 min

Show notes

Nuclear fusion has long been viewed as a transformational energy breakthrough, capable of delivering abundant, zero-carbon at operation energy by recreating the same reaction that powers the sun. Recently, a series of scientific milestones, rising electricity demands and the global competition for energy have moved the conversation from theoretical possibility towards commercial reality.​

In this episode of the Barclays Brief, Jordan Isvy, Sustainable Investing Research Analyst, joins Patrick Coffey, Global Head of Product Management Group, Research, to explain the science behind fusion, the challenges on the path to commercial deployment and timelines for adoption. They explore the factors driving the focus on fusion, including AI-driven demand, and where progress is accelerating across the globe. ​

For investors, the opportunity may begin long before fusion reaches the grid. The discussion covers emerging opportunities across the value chain and what a future powered by nuclear fusion could look like.​
