WHAT IS CARBON CAPTURE?
Q.HOW DOES IT WORK?
A.It is a strategy to prevent carbon escaping into the atmosphere. Power plants collect the carbon and store it in old gas and oil fields, the ocean or coal seams.
Q.CAN IT GENERATE PROFITS?
A.As companies exceed carbon quotas they could be forced to pay companies like SSE to offload some of their waste. More eco-friendly companies will have unused carbon credits to sell.
Q.WHAT IS THE PROCESS?
A. The carbon dioxide is compressed into a liquid state which makes it easy to transport and deposit or dispose of. The process is carried out post-combustion which means the carbon dioxide is cleaned before being sent away.
Q.WHAT ARE THE OBSTACLES?
A. Although the government says it is keen to push ahead with carbon capture, campaigners have claimed the building of storage centres could harm wildlife.
