The risks associated with climate change have been the subject of much debate in recent years. Today, most experts think that these risks are real and directly linked to the emission of greenhouse gases, especially CO2. Recent decades have witnessed a large rise in CO2 emissions, thereby increasing the concentration of CO2 in the atmosphere. Scenarios established by the IPCC (Intergovernemental Panel for Climate Change) show that the CO2 content could rise from a current value of about 360 ppm to a value that, unless preventive measures are taken, could exceed 1000 ppm by the end of the century.
Among the options for mitigating the risks of climate change due to greenhouse gas emissions, CO2 capture, transport and geological storage (CCS) appears as one of the most promising options, specially applicable to large CO2 emitters like thermal power stations, steal and cement industries.
The major challenges which have to be addressed are:
- to store huge amounts of CO2,
- to reduce the costs, mainly for capture,
- to ensure the long-term safety of the geological storage.
This paper will describe and analyze the main issues - both technical and non technical - involved for achieving a large deployment of the technologies of capture, transport and storage which are required.
Examples of ongoing large R&D effort will also be given, like the CASTOR project which aims at a significant technology development for the separation of CO2 from low pressure and diluted flue gases. Planned medium and large-scale demos of power production with CCS will also be briefly discussed, showing the strong wish from the industry, the research community and the public bodies to accelerate the development and the validation of technologies for achieving a strong cut in CO2 emissions.
