This UKCCSRC (UK Carbon Capture and Storage Research Centre) Call 1 project involved the development, testing and validation of a two-fluid transient flow model for simulating outflow following the failure of high pressure CO2 pipelines is presented. The project made use of experimental data and used experimental data available from other UK/EC funded projects. The model developed accounts for thermal and mechanical non-equilibrium effects during depressurisation by utilising simple constitutive relations describing inter-phase mass, heat and momentum transfer in terms of relaxation to equilibrium. Pipe wall/fluid heat exchange on the other hand is modelled by coupling the fluid model with a finite difference transient heat conduction model. This paper describes the model, the details of its numerical solution and its validation as well as parametric analysis of relevant parameters. http://www.sciencedirect.com/science/article/pii/S1750583614002394, DOI: 10.1016/j.ijggc.2014.08.013.

The permeability of single fractures, pairs of conjugate fracture pairs, and 256 fracture networks, is numerically computed using a multi-scale permeability method. For fracture networks, the geometries of the files are contained in 3dm files. The results are presented in a series of json text files. The method to compute permeabilities is described in the PhD thesis entitled "Multi-scale modelling of thermohydro-mechanical-chemical processes in fractured rocks" by Philipp Lang, Imperial College London, supervised by Adriana Paluszny and Robert W. Zimmerman.
Numerical model predictions of present-day solid Earth deformation and gravity field change due to ongoing glacial isostatic adjustment processes. Model accounts for 3D spatial variations in Earth rheology using a finite element approach.
Coordinated by Haroun Mahgerefteh at UCL, the EC funded FP7 CO2QUEST project addressed the main challenges associated with determining the optimal composition and purity of CO2 product streams derived from carbon capture systems for enabling its safe and economic transport and storage. The project brought together academics and major stakeholders to perform computational studies backed-up by large-scale experiments aimed at identifying CO2 mixtures that have the most profound impact on the different parts of the CCS chain. The project ran from March 2013 until June 2016, involving 9 partners across Europe, including from Canada and China. It resulted in over 100 peer reviewed journal publications and conference proceedings, three international conferences and several newsletters, receiving the IChemE Highly Commended Global Process Safety Award in 2016.
