Carbon-dioxide capture and storage technologies

Carbon-dioxide capture and storage technologies are an important part to achieve a low-carbon economy in the future.The carbon-dioxide capture and storage is divided into three stages:(1) capture,(2) transport phase,and(3) storage phase.By adding an oil and gas recovery stage to the three stages mentioned above,the CCS chain is formed.Many countries in the world, including China,have tried to practise carbon-dioxide capture and storage projects.However,there are still major legal issues restricting the development of carbon capture and storage.There is still a long way to go for a harmonious development of the CCS.
