Sammendrag
A number of projects have been launched with the aim to capture CO2 from a power plant based on fossil fuels. These projects vary in type of technology for capture of CO2 and they vary in the range of size and strategies for handling the captured CO2. The components used in the different capture processes are at different level of development, depending also on if it is a pre-, oxy- or post-combustion CO2 capture concept. In this presentation, the current levels of maturity for the different process units in power cycles with CO2 capture are described, identifying the main challenges and issues for further development. This includes processes such as air separation (ASU), shift reactors (HTS/LTS), gasifiers, reformers, gas turbines (especially for pre-combustion), absorption systems (amines – high/low pressure) and CO2 conditioning/requirements for transportation and storage or EOR/EGR. The industrial projects are described, including the CO2 capture concepts to be used and how the CO2 will be handled. This can then be seen in relation to the description of process components and the maturity of those to form an overall view of maturity of the planned industrial projects. The current available information on storage sites, including EOR/EGR, is described in relation to the planned projects. Some of this work is done within the frames of sub-projects 2, 3 and 4 of Dynamis (Towards Hydrogen and Electricity Production with Carbon Dioxide Capture and Storage), a project pointing out potential manufacturers for the components required in a pre-combustion CO2 capture power plant and the level of maturity – both for natural gas and for coal as fuel. Dynamis has a clear emphasis on commercially available technology from manufactures today, and the current state of technology has been evaluated with that in mind.
