As fossil fuel use and greenhouse gas emissions continue to rise, there is renewed interest in what can be done to capture carbon dioxide. Until now, most of the investment in carbon capture has gone into projects to take those emissions and store them underground forever. But what if we could make use of that captured carbon? 

To find out what role carbon capture and utilization, or CCU, could play in tackling climate change, host Ed Crooks is joined by three experts in the sector. He is joined by Sarah Lamaison, who is the CEO and co-founder of CCU start-up Dioxycle, Tim van den Bergh, the climate tech innovation lead at the World Economic Forum, and John Ferrier, a senior research analyst at Wood Mackenzie. Together they unpack what CCU actually is (and isn’t), and where it can deliver the biggest punch; for example in the chemical industry, which is a sector in large part built on carbon.

Sarah explains how Dioxycle’s carbon electrolysis can turn carbon dioxide and carbon monoxide into high-value molecules such ethylene using electricity and water. It is effectively “dual” decarbonization: it uses captured carbon instead of fossil feedstock, and also avoids process emissions.

But despite those compelling advantages, CCU faces some steep challenges. The gang examines the policy landscape, and the economics that can make or break CCU projects. John outlines why support has historically skewed toward carbon storage rather than utilization: it offers measurable, near-term reductions and simpler business models. To accelerate the growth of CCU, it needs clearer incentives, and standardized lifecycle assessment of carbon emitted and avoided. 

Sarah compares Europe’s current framework, which can disadvantage CCU, with more supportive tax credits that are available in the US. She explains that the choice of product to be made using CCU really matters. For fuels, conventional feedstocks such as crude oil and natural gas are hard to beat on cost. For complex chemical pathways, there is room for CCU to undercut incumbents as efficiency improves. Tim looks at the system level, calling for global, aligned policies, early markets in cost-competitive niches and “patient capital” to bridge the valley of death that innovative companies face as they scale up.

There’s a strong case that can be made for CCU, if policy, finance, and industry can travel in the same direction. This episode explains what would be needed to make that a reality, taking businesses from promising pilots to deployment at scale and cost parity with conventional feedstocks.
