Background of Sinopec CCS

The great threaten for environment• CCS is an effective way to reduce greenhouse gas emission

• China is going to reduce the intensity of CO2 emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005.• China carries out a series of policies to promote CCS

• The social and environmental responsibilities• Having CO2 capture resources(refineries, natural gas with high CO2 content, plant, etc.)• Having a vast amount of reservoirs suitable for CO2–EOR and storage, CCS+EOR

Introducing Sinopec






Demands for CCS Development I. CCUS-related laws, regulations and standards are urgently

needed- Make clear the competent departments and approval procedure

- Make clear the nature of stored CO2

- Make clear the ownership of CCS projects

- Develop CCUS-related technical specifications as early as possible

- Develop CO2 emission reduction calculation method and certification program



II. Establish the fiscal & tax policies / industrial policy to incent

the CCS demonstration effectively.

III. To strengthen the sharing of existing knowledge and

experience.
