CCGT with Carbon Capture and storage¤

Introduction¤

Combined cycle gas turbines are a type of power plant designed to maximise the power generation from a given fuel, usually natural gas, by combining two cycles. The first cycle is a conventional Brayton cycle (gas turbine), in which natural gas is burnt in the presence of compressed air, generating hot gases. Those are expanded to near-atmospheric pressure, but their temperature at the turbine outlet can be as high as 600°C. In other words, a significant amount of energy is wasted to the environment as thermal losses, and the concept of a combined cycle is to implement a second cycle, normally a steam Rankine cycle, to convert part of this waste heat of the flue gases into electricity.

CCGT with Carbon Capture and Storage (CCS) includes the process of capturing carbon dioxide (CO2), transporting it to a storage site, and storing it, with the aim of avoiding an eventual release in the atmosphere. It is a potential means of mitigating CO2 emissions from human activities, to prevent global warming and ocean acidification
