A new synthetic method for studying phase behaviour is described using Attenuated Total Reflection (ATR) spectroscopy. The method has been developed to provide relevant information on the solubility of water in CO2. The dew point of water has been determined at three different pressures, viz. (4.05, 5.05 and 6.03) MPa with mole fractions of water between 0.01 and 0.04. The data obtained fill the gap in the literature in these regions of pressures and temperatures and could be of high importance in the context of Carbon Capture and Storage (CCS) technology. Indeed, the presence of water in the captured CO2 could damage the pipeline used for CO2 transport. Hence, it is very important to have a fully understanding of the behaviour of the (CO2 + H2O) mixtures in wide range of temperature relevant for CCS.

The RISCS guide summarises the conclusions and recommendations developed by the RISCS Consortium, based on four years of research into the potential impacts of leakage from CO2 storage sites. The report has been developed in parallel with the experimental research, field-based investigations, modelling studies and analysis undertaken during the RISCS project. The Report can be downloaded from http://www.riscs-co2.eu/UserFiles/file/RISCS_Guide/RISCS_Guide.pdf.
The data consists of an extended abstract submitted to '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. The CO2-rich St. Johns Dome reservoir in Arizona provides a useful analogue for leaking CO2 storage sites, and the abstract describes an analysis of the fault-seal behaviour at the site. http://earthdoc.eage.org/publication/publicationdetails/?publication=82673.
This poster on the UKCCSRC Call 2 project Process-Performance Indexed Design of Ionic Liquids for Carbon Capture was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-199. The elevated cost of carbon capture and storage (CCS) is currently hindering its implementation at large scale. We aim to design a 'perfect' solvent for the capture of carbon dioxide (CO2). The design of the solvent is based on process performance indexes.

The dataset contains 15 plots and data for time-dependent pressures and temperatures at various locations along a 2582-m-long well and at various simulation times. The realistic scenarios taken into considerations are applied to the Goldeneye depleted reservoir in the North Sea. Pure CO2 is injected into the well and then discharged in the Goldeneye reservoir. Six different scenarios are considered: three different injection durations (linear ramp-up of the inlet mass flow rate from 0 to 33.5 kg/s over 5 minutes, 30 minutes, and 2 hours) and two different upstream temperatures (278.15 K and 283.15 K). Data is currently restricted until publication.

The dataset contains experimental data of the preparation of a photocatalytic membrane and its application in CO2 capture and utilization. The experiments were carried out in the Tang’s and Lan’s groups at the Department of Chemical Engineering, University College London during June-November 2020. Specifically, the data shows the preparation of cucurbituril and copper oxide which were empolyerd to prepare the photocatalytic membrane together with functional polymers. Preliminary results of the photocatalytic membrane for CO2 capture and utilization were also included. Funded by UKCCSRC 2020 Flexible Funding Call.
Free energy calculations of noble-gas containing liquid iron and silicate melts at 50 GPa (3500 K) and 135 GPa (4200 K). The chemical potentials of noble gases can be obtained from these calculations. The Gibbs free energy of a series of iron and silicate melts with different concentrations of He were calculated. Then the chemical potentials of He can be derived from the concentration dependent Gibbs free energies. The chemical potentials of Ne, Ar, Kr and Xe were calculated by using the alchemical free energy method, where one He was converted to Ne, Ar, Kr or Xe gradually.
