There are several types of underground storage sites. It is then compressed to a near-liquid state and transported to storage sites via pipeline, train, or truck. ![]() In conventional coal-fired power plants, carbon can be captured post- combustion using a chilled ammonia solution, which seizes the pollutant from flue gas before it is released into the atmosphere. In integrated gasification and combined cycle power plants, carbon dioxide is removed pre-combustion in the gasification process. coal power plant commenced operations at the Barry Electric Generating station in 2012.Ĭarbon dioxide can be captured either pre- or post-combustion. However, the technology is still in the development stage and has not yet been proven safe and effective at commercial scale over the long term. Because carbon dioxide is a greenhouse gas that traps heat in the atmosphere, CCS is often discussed as a potential solution to climate change.
