Pre-combustion capture gasifies fuel to create a synthesis gas, allowing for higher purity capture, while oxy-fuel combustion burns fuel in pure oxygen, creating a flue gas that is mostly CO2 and water vapor. How CCUS Technology Works Across the Value Chain The foundation of any effective system is a clear understanding of the workflow, and CCUS is no different.
CCUS Technology Cost Capture Innovation
Captured CO2 can be transformed into a feedstock for a variety of products, ranging from synthetic fuels and concrete aggregates to carbonates used in manufacturing. Once captured, the CO2 is compressed into a supercritical fluid and transported via pipeline to a suitable geological formation.
As industries such as cement, steel, and heavy chemicals struggle to reduce emissions through electrification alone, CCUS emerges as a necessary solution for achieving deep, permanent mitigation. Capture, Transport, and Permanent Storage The first pillar is capture, which can be achieved through several distinct methods.

The final and most permanent step involves injecting the CO2 deep underground into porous rock formations, such as depleted oil and gas reservoirs or saline aquifers, where it is trapped by impermeable rock layers. From the initial capture at the emission source to the final storage or product, every step is critical to the overall integrity and permanence of the solution.
