Dense Phase CO2 PipeLine TRANSportation (COOLTRANS)

Funded by National Grid, 2011-2013

Warwick Lead: Professor Jennifer X Wen

National Grid is pursuing plans to transport CO2 through pipelines from the proposed Don Valley Power Project near Doncaster to Saline Aquifers off the Yorkshire coast. There is also an aspiration to develop the first pipeline into a network configuration that links up multiple CO2 emitters in the Yorkshire and Humberside area. In order to progress the technical work required, National Grid has initiated the dense phase CO2 PipeLine TRANSportation –(COOLTRANS) programme of research to address knowledge gaps relating to the safe design and operation of onshore pipelines for transporting anthropogenic, high pressure, dense phase CO2 from emitters to storage. A number of large scale experiments have been carried out to gain insight into CO2 behaviour during different release scenarios and to confirm the pipeline toughness requirements in order to prevent running fractures [4-6]. The present study is part of the COOLTRANS research programme. Its specific aim is to develop and validate predictive tools for modelling large scale CO2 dispersion simulations. Such predictive tools will provide quantified information on the CO2 concentrations in the nearby regions following a potential release and hence guide operators to ensure that the pipeline routes will have sufficient safety distances from nearby business premises and residential buildings.
