Data supporting 'Effective permeability tensors of three-dimensional numerically grown geomechanical discrete fracture networks with evolving geometry and mechanical apertures', submitted to the Journal of Geophysical Research: Solid Earth. Authors: Robin N Thomas (corresponding, robin.thomas11@imperial.ac.uk), Adriana Paluszny, Robert W Zimmerman. Department of Earth Science and Engineering, Imperial College London. Contents: For each GDFN, the geometry at each growth step. Additionally, for GDFN E, the data shown in the paper (aperture and flow distributions, figures 6 and 7) are provided, including the displacement for the mechanical case, and pressure distributions which were not shown in the manuscript. For the two SDFN sets, the geometry of the four datasets shown in figures 4 and 5 are provided. Notes: - The geometry files are provided in the .3dm format, Rhinocerous' native format (https://www.rhino3d.com/). A free trial of Rhinocerous can be used to explore the files, and can convert them to a range of other CAD file types. - VTK files can be viewed using free software such as Paraview (https://www.paraview.org/). These contain the meshes. - Fracture surface areas reported in the paper are derived from the mesh, rather than the geometry. The mesh approximates the geometry leading to a different surface area than those measured in the geometry (3dm) files. - The SDFN datasets are shown before trimming the parts of fractures which are outside the domain. These parts are trimmed when they are imported to ICGT.

The project is mainly experimental in nature. Sieved samples of a variety of UK, Canadian and Spanish limestones will be pre-calcined and sintered at elevated temperatures to differing extents under various steam atmospheres, potentially with the addition of salts. The relativities of the produced materials will be tested, initially in a thermogravimetric analyser and subsequently in a small electrically-heated fluidised bed. If time allows, extended work will be conducted at elevated pressure (10 - 20 bar), more typical of conditions in pre-combustion capture. In essence, the aim of the project is to develop inexpensive sorbents for CO2 to work within an efficient thermodynamic cycle. Grant number: UKCCSRC-C2-206.

Data associated with the UKCCSRC thermal oxygen project - UKCCSRC-1-39, including rig design, reactor and burner design diagrams, heat transfer calculations for thermal oxygen, CuO-AI2O3 particles preparation procedure document, etc. Data is restricted.

Imperial College has modelled and designed from first principles a counter-flow thermal oxygen reactor using CuO (MnO) based particles as an oxygen carrier, for replacing the burner in conventional coal fire power plant. The length of the reactor depends on the required falling distance for CuO particles to heat up and complete the decomposition. Initial calculations indicated that this was higher than hoped (500 mm). The design is being optimised. A prototype burner has been built and tested according to the design. After intense tests and some modifications on the prototype, we managed to show some encouraging results as a proof of concept. It is demonstrated that under the current design, there is strong evidence that the particles exhibited sufficiently fast kinetics to release the required oxygen to support complete combustion of propane fuel in an initially sub-stoichiometric flame. The results have led to the construction of a second version of the burner, with improved designed, and a more powerful surface mixed burner capable of much higher heat duty than the current one. The new version of the burner will be tested during the next few months. Part II of the report is restricted and not available for download.

UKCCSRC Call 2 Project C2-199. Datasheet providing detailed stream information pertaining to an Ionic Liquids (IL)-based CCS process. This data arises from a process model developed at Imperial College London.

While chemical looping (combustion, CLC) is a promising technology for carbon capture, however many questions still remain as to its applicability at an industrial scale. In Chemical looping combustion a metal oxide is shuttled back and forth between a fuel and air reactor, picking up oxygen in the air reactor and transferring it to the fuel reactor. The fuel is never mixed with the nitrogen from the air, so a stream of CO2 and H2O is produced directly from the fuel reactor; this potentially makes the integrated power production and CO2 capture system highly efficient. Most CLC and CLOU schemes envisage using fluidised beds in which the solid fuel is intimately mixed with the oxygen carrier, or mixing of the solid fuel particles. This project aims to push forward chemical looping within the UK and integrates both experimental work and theoretical analysis to result in the first large-scale demonstration of CLC within the UK. Grant number: UKCCSRC-C1-39.

Grant: NE/N016173/1.The data presented herein comprises raw and segmented X-Ray micro-CT data, CMG simulation files and Matlab processing files for the paper 'Representative elementary volumes, hysteresis and heterogeneity in multiphase flow from the pore to continuum scale'. The data is organised as Core 1 and Core 2 respectively. Full core scans are obtained at a resolution of 6 microns. Region of interest (ROI) scans are obtained at 3.45 micron and 2 micon (core 1) and 3.5 micron (core 2). Resolution information is contained within the file names. Voxel sizes in the image files can be changed to match these values. Experimental post-processing files contain the upscaled saturations and porosity values in 3D, which are used in the paper. It also contains the pore-filling analysis. The CMG simulation files contain the input deck, 3D digitial core information (porosity, capillary pressure) needed to simulate both the drainage and imbibition core floods, with corresponding Matlab analysis files. These are Bentheimer outcrop cores obtained from Shell, Amsterdam. It is a shallow marine rock, deposited during the Lower Cretaceous. It outcrops between Enschede and Schoonenbeek in the Netherlands.

This poster on the UKCCSRC Call 2 project Advanced Sorbents for CCS via Controlled Sintering was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-206. Calcium looping shows significant promise for CO2 capture. The process can lead to an energy penalty as low as 6 - 8 % including the compression of the lean CO2 stream, compared to 9.5 - 12.5 % for amine-based post-combustion capture. To implement this technology on an industrial scale, a large quantity of CaO-based sorbent will be required, therefore the sorbent must be capable of being regenerated and reused.
