Carbon dioxide capture and storage is now established in OECD countries’ energy policies and R&D programmes as a potential contributor to climate mitigation strategies. Post combustion capture allied to improved efficiency power plant looks likely to be a major element for new plant as markets develop – particularly so in developing countries where there is a clear preference for using the best established technologies for power generation. Retrofit to established plant is also technically feasible although less economically attractive for ageing, less efficient assets. Since the previous workshop a number of generators in Europe and Canada have expressed interest in the possibilities of demonstrating the technology at full scale and a major pilot plant operation under the EU CASTOR programme has commenced at a power station near Esbjerg in Denmark. About a quarter of the workshop participants used the opportunity to visit this new facility on the day previous to the workshop – thanks from all participants to Elsam for hosting this visit.
Over the six years in which this workshop series has existed, we are seeing more and more researchers coming into the field and some exciting new developments covering new solvent formulations, process engineering innovation and increasingly sophisticated process economic modelling. This report contains presentations on a variety of fundamental developments including for the first time a presentation on the opportunities of using spray absorption of CO₂. There is also our first report on possible environmental impacts, although it must be borne in mind that this arises from experience at Statoil’s Sleipner capture operations in the North Sea.
Our authoritative, peer-reviewed publications cover topics that include carbon capture, transport, storage, monitoring, regulation, and more.
