Publication Overview
This study examines the design issues and costs of collecting CO2 captured from multiple distributed sources down to quantities of 5000 tpa. It includes a spreadsheet model for sizing pipelines in a branched collection network with multiple pressure levels. This model also estimates overall collection costs including those for compression using unit costs for construction in the UK.
Publication Summary
The costs of collecting CO2 from moderate sized industries are not excessive and should be considered when planning CO2 pipeline and storage infrastructure. However alternatives such as centralizing CO2 capture using pre-combustion and distributing hydrogen as fuel to nearby industries may offer a more economic solution. Extending the collection network to encompass smaller sources will increase the need to lay pipelines near places where the public live, work and travel and this has safety implications particularly if supercritical conditions are used.
Much of extended networks could be constructed using plastic materials thus eliminating any exposure to corrosion risks.
It was apparent from the two seminars conducted during preparation of this report that collaboration and information exchange will be needed between those operating in heavy industrial zones if optimum choices to reduce GHG emissions are to be made and appropriate shared infrastructure and facilities built.
