EU Project Report: Choosing good sites for storing CO2 underground Research highlights from the EU FP7 SiteChar Project
The objective of the EU SiteChar Project was to facilitate the implementation of CO2 geological storage in Europe by developing a methodology for the assessment of potential storage sites and the preparation of storage permit applications. Research was conducted through a strong collaboration of experienced industrial and academic research partners aiming to advance a portfolio of sites to a (near-) completed feasibility stage, ready for detailed front-end engineering and design and produce practical guidelines for site characterisation. SiteChar was a 3 year project supported by the European Commission under the 7th Framework Programme. This report introduces the lay reader to the research and concepts developed in the SiteChar project and can be downloaded from http://www.sitechar-co2.eu/SciPublicationsData.aspx?IdPublication=351&IdType=557.
Shallow Gas Offshore Netherlands - The Role of Faulting and Implications for CO2 Storage - poster at 4th International Conference on Fault and Top Seals
The data consists of a poster presented at 'The Fourth International Conference on Fault and Top Seals', Almeria, Spain, 20-24th September 2015. The abstract describes work carried-out on behalf of the 'Fault seal controls on CO2 storage capacity in aquifers' project funded by the UKCCS Research Centre, grant number UKCCSRC-C1-14. Shallow gas accumulations in the Netherlands sector of the Southern North Sea provide an opportunity to study their coincidence with faulting. Although difficult to attribute the occurrence of shallow gas to leakage of thermogenic fluids from depth (indeed shallow-sourced biogenic gas is common in the North Sea), evidence suggests a relationship, and the common attributes of the faults provide indications of the conditions under which faults in the region may leak, providing a useful indications of factors that should be avoided during CO2 storage operations.

UKCCSRC Call 1 project posters and presentations: Mixed matrix membranes preparation for post combustion carbon capture (Mar 2013 to Dec 2015)
Posters and presentations from the UKCCSRC Call 1 Project: Mixed matrix membranes for post combustion carbon capture (Mar 2013 to Dec 2015). Membrane processes are a promising alternative to the more classical post-combustion capture technologies due to the reduced maintenance of the process, the absence of dangerous solvents and their smaller footprint. This project aims at supporting the development of new mixed matrix membranes for post-combustion applications. Mixed matrix membranes (MMMs) are composite materials formed by embedding inorganic fillers into a polymeric matrix in order to overcome the upper bound and combine the characteristics of the two solid phases: mechanical properties, economical processing capabilities and permeability of the polymer and selectivity of the filler. Despite several studies on the concept, the interactions between the two phases and their effect on the transport properties are not well understood. Yet, this fundamental knowledge is crucial in order to design the reliable materials needed for real-world-applications.
Scottish Carbon Capture & Storage (SCCS) Working Paper 2010-03: Benchmarking worldwide CO2 saline aquifer injections
Technical report, component of ‘Progressing Scotland’s CO2 storage opportunities’ 2010. Carbon Capture, Transport and Storage is a very active field of research, especially for the past decade. From the UK perspective, a commercially crucial aspect is the saline aquifer research, since there are predicted to be vast storage capacities in the sedimentary formations of the North Sea. The report reviews the ongoing work on practical injections of CO2 as research tests for storage projects and specifically focuses on industrial sized saline aquifer injections.

Geomechanical Properties of the Carboniferous Middle Coal Measures: Influence on fracture fluid flow and frictional stability during geothermal utilisation (UKGEOS Glasgow)
UKGEOS and Core Sample Analysis. Geomechanical testing was performed to determine triaxial compressional strength, tensile strength, frictional strength and permeability of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole, UK Geoenergy Observatories (UKGEOS), Glasgow, United Kingdom. Frictional strength tests were also performed on cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole, Glasgow, United Kingdom. In total twenty-three tensile strength tests were performed on ten sampled intervals, and seven porosity measurements pre-and post-failure were taken. Nine triaxial compressive strength tests and twenty-one frictional strength tests were performed, with permeability measured both before and after failure or shear respectively. From compressive strength tests we also determined the Young’s modulus and Poisson’s ratio. Results of X-Ray Diffraction are also included in the dataset.
UK Miscellaneous: Report: A preliminary feasibility study for the underground disposal of carbon dioxide in UK 1991 (THE first UK CO2 storage publication)
This is THE first CO2 storage publication produced in the UK. The Association of the Coal Producers of the European Community are agreed that immediate action is required to reduce the build up of greenhouse gases in the atmosphere (Harrison, 1990). This is considered necessary even though the effect of these gases on global climate and the human race, are very uncertain mainly because the factors and processes affecting climatic change are poorly understood. http://nora.nerc.ac.uk/511485/
