Abstract In October 2009, the International Energy Agency’s CCS Technology Roadmap was launched at the Carbon Sequestration Leadership forum (CSLF) Ministerial Meeting in London. The Roadmap builds on the IEA BLUE Map scenario that leads to the stabilisation of CO2 emissions at 450 ppm by 2050. Achieving this scenario will require an energy technology revolution involving a portfolio of solutions: greater energy efficiency, increased renewable energy technologies and nuclear power, and the near decarbonisation of fossil fuel-based power generation via carbon capture and storage (CCS). In this scenario CCS contributes almost 20% to the total emissions reductions required in 2050. Recommendations are made in the IEA CCS Roadmap on what is required to achieve this level of deployment not only technically, but also from a financial and regulatory point of view as well as in terms of public engagement and international collaboration, including the sharing of knowledge. This paper looks at progress made against these recommendations in the 12 months since the release of the roadmap. • Analysis undertaken by the IEA consistently identifies a significant role for CCS in mitigating global CO2 emissions. IEA analysis suggests that there will be a need to capture and store 10 Gt CO2 per year in 2050, from 3400 projects globally to achieve the BLUE Map emissions reduction targets. • Significant progress is being made to launch large-scale demonstration facilities across the globe, with some 80 large-scale integrated demonstration projects identified. As of April 2010, public funding commitments were in the range of USD 26.6 billion to USD 36.1 billion. • While 5500 km of CO2 pipelines already exist and further infrastructure development is planned, it is however clear that to enable large-scale deployment of CCS, more joint planning of CO2 transportation infrastructure is required globally. • The status and availability of data on CO2 storage varies significantly around the world and is potentially a major constraint to rapid, widespread CCS deployment. In regions with the potential to store large volumes of CO2, a concerted effort will be required to characterise the basins in sufficient detail. • Much progress has been achieved in the legal and regulatory area. The first movers in establishing legal frameworks have generally been OECD countries. It is now important that the large emerging economies start developing their legal and regulatory frameworks. • Public awareness and acceptance is a key element in making CCS possible. Public concerns are legitimate and require a close dialogue and sharing of information with the local population. While companies developing transport and storage will need to lead on the engagement processes, governments and politicians have a vital role to play. • Several initiatives are in place for international dialogue and collaboration on the development and deployment of CCS. • While much progress has been made, many challenges still remain if CCS is to deliver at the scale required. The challenges are well-known and require concerted action by industry, governments, international organisations and civil society. Continued political leadership remains absolutely essential.
