Presentation Transcript

  1. CO2 capture and storage Presented by Heleen de Coninck Energy research Centre of the Netherlands

  2. Fuels Processes Transport Storage options What is CO2 capture and storage? IPCC, 2005

  3. Global role of CO2 capture and storage • Developed and developing countries • Power and industry IEA, 2008

  4. CCS: which CO2 sources? Coal-, gas- orbiomass-fired power Biomassconversion Cement Iron/steel Refineries Natural gas production (“Sweetening” of gas) Ammonia production Ethyleneproduction

  5. Storage prospectivity Highly prospective sedimentary basins Prospective sedimentary basins Non-prospective sedimentary basins, metamorphic and igneous rock Data quality and availability vary among regions Current CCS projects Snøhvit Sleipner In-Salah Weyburn/Midale Images Courtesy of BP, Statoil, and PTRC

  6. CCS has many challenges • Energy requirements for capture • Makingitunattractive in countrieswithenergyshortages • Limitedstoragepotential • Best in oil/gas producingregions • Costs, absence of incentive • Risk of impermanentstorage • Legal framework • Environmental impacts • Public perception

  7. CCS is mature in some sectors and regions, but in the demonstration phase in others • Analysis shows lower global mitigation cost with CCS than without it, though costs are high • Some industries cannot achieve deep emission reductions without CCS • The only reason to do CCS is CO2 reduction • CCS has not much to do with access to energy • But can be part of an industrial development strategy Main messages
