What is CCS?

Power station in a fieldCarbon Capture and Storage (CCS) is a technology that can capture up to 90% of the carbon dioxide (CO2) emissions pro­duced from the use of fossil fuels in electricity generation and industrial processes, preventing the carbon dioxide from entering the atmosphere.

Furthermore, the use of CCS with renewable biomass is one of the few carbon abatement technolo­gies that can be used in a 'carbon-negative' mode ­– actually taking carbon dioxide out of the atmosphere.

The CCS chain consists of three parts; capturing the carbon dioxide, transporting the carbon dioxide, and securely storing the carbon dioxide emissions, underground in depleted oil and gas fields or deep saline aquifer formations.

First, capture technologies allow the separation of carbon dioxide from gases produced in electricity generation and industrial processes by one of three methods: pre-combustion capture, post-combustion capture and oxyfuel com­bustion.

Carbon dioxide is then transported by pipeline or by ship for safe storage. Millions of tonnes of carbon dioxide are already transported annually for commercial purposes by road tanker, ship and pipelines. The U.S. has four decades of experience of transporting carbon dioxide by pipeline for enhanced oil recovery projects.

The carbon dioxide is then stored in carefully selected geological rock formation that are typically located several kilometres below the earth's surface.

At every point in the CCS chain, from production to storage, industry has at its disposal a number of process technologies that are well understood and have excellent health and safety records. The commercial deployment of CCS will involve the widespread adoption of these CCS techniques, combined with robust monitoring techniques and Government regulation.
