2、e to climate change :According to the Intergovernmental Panel on Climate Change (IPCC), Carbon Capture and Storage (CCS) will play a vital role in the strategy to meet ambitious emission reduction goals, as a “bridge” to sustainable energy system. CCS is technically feasible, but there are still rem
