Summary

This special wrap-up episode of Interchange Recharged takes listeners on a fast tour of the entire carbon capture value chain, from industrial emitters and LNG developers to UK transport and storage pioneers. Host Sylvia Leyva Martinez, Research Director at Wood Mackenzie, brings together three leaders shaping how CCUS moves from theory to reality.

First, James Lopez, Subsurface CO₂ Storage Advisor at CEMEX, explains why cement’s process emissions make it one of the hardest sectors to decarbonise and why storage certainty is now the key enabler for investment. He shares how CEMEX is identifying and evaluating CO₂ storage hubs across global sites, and why capture without a permitted storage solution is a business risk few emitters can take. “CCUS doesn’t work if you only have the C,” he says, “you need the full chain.”

Next, Glenn Wilson, Chief Financial Officer at Coastal Bend LNG, discusses how LNG economics and carbon capture can work hand in hand. Designed from day one as a low-carbon project, Coastal Bend LNG is integrating capture across both pre-treatment and post-combustion stages, aiming for near-zero emissions. Glenn explains how 45Q tax credits and the sale of verified environmental attributes create a dual-revenue model, and why tokenising the carbon intensity of each LNG cargo could redefine transparency in global energy trade. “We’re not just reducing emissions,” he says, “we’re creating a new market for verified carbon value.”

Finally, Nick Terrell, Executive Director at Carbon Catalyst, joins from the UK to reveal how depleted gas fields are being repurposed into next-generation carbon storage sites. Following the country’s first offshore CO₂ injection test, he shares how reusing North Sea infrastructure is cutting costs, driving bankability, and opening the door to cross-border storage for European emitters. As policy alignment grows between the UK and EU, Terrell argues that liberalisation and private capital will be the next accelerators. “Once we have more FIDs,” he says, “finance, technology, and data will do the rest.”

From the cement kiln to the seabed, this episode captures the energy and optimism emerging across the CCUS ecosystem - a clear sign that carbon capture is moving from cautious planning to confident execution.

Welcome back to the Interchange Recharge Podcast. I'm Sibial I'm Sivial I'm Sivio L'Ivo Martinez,

0:07.5

research director at Wood McKenzie, and host of the show. We're wrapping our coverage of the

0:12.3

Houston CCUS event with a fast tour of the whole value chain. There was so much interesting content,

0:18.4

we decided to do a special episode to tie it all together,

0:21.5

and we had great interviews we had to show even when it's been a week after the conference.

0:26.5

We'll be jumping straight into the emitter seat, then the LNG economics,

0:31.0

and finally UK transport and storage.

0:33.5

What clears, what doesn't, and what's next.

0:36.1

First up, the emitter perspective.

0:38.0

Semant is around 8% of global CO2 emissions,

0:41.5

and these process emissions don't vanish with efficiency tweaks.

0:45.0

Here's James Lopez, CO2 subsurface storage advisor at CMEX,

0:48.9

unsubesurfaced uncertainty, permitting timelines,

0:51.6

and why you can't green light capture without storage certainty.

0:55.7

James, welcome to the show.

0:57.3

Thank you.

0:57.9

Thank you for inviting me.

0:59.1

So tell me a bit more about, well, I think many people in your audience know about

1:04.1

Samex, but tell me a bit more about the company anyways and your role there.

1:08.0

Yeah, so Semex is just a global leader in providing cement to the world. You know,

1:14.6

it's a building material. Cement is an important part of infrastructure. It's a important part of our life.

1:20.1

We can't get away from it, right? It's everywhere we go. My role with CMEX is as a CO2 subsurface
