This poster on the UKCCSRC Call 2 project Investigating the radiative heat flux in small and large scale oxy-coal furnaces for CFD model development and system scale up was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-193. Oxy-fuel (coal or biomass) combustion significantly changes the heat transfer properties of power plant furnaces. Thus future power plants using oxy-fuel technology will rely greatly on computational modelling. This project aims to collect combustion and heat transfer data from both small and large scale furnaces and to validate the computational model in order to make it ready for future technology scale up. Specific objectives are: • Take measurements at the 250 kW oxy-coal furnace at PACT national facilities in Sheffield, including combustion and heat transfer data. • Take measurements at a 35 MW oxy-coal furnace in China. • Validate CFD models developed and investigate the combustion and heat transfer properties in both large and small furnaces.

This poster on the UKCCSRC Call 1 project Multiphase flow modelling for hazard assessment of dense phase CO2 pipelines containing impurities was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-07. The aim of the project is to develop and validate experimentally a heterogeneous flow model for predicting the transient depressurisation and outflow following the puncture of dense-phase CO2 pipelines containing typical impurities. Given that CO2 is an asphyxiant at high concentrations, this information is pivotal to assessing all the hazard consequences associated with CO2 pipeline failure, including fracture propagation behaviour, atmospheric dispersion, emergency shutdown valve dynamics and emergency blowdown.

This poster on the UKCCSRC Call 2 project Quantifying Residual and Dissolution Trapping in the CO2CRC Otway Injection Site was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-204. For a wide adoption of the Carbon Capture and Storage (CCS) technology, it is essential to provide a commercial operator with a reassurance of the predictability of their proposed site for CO2 storage through geochemical monitoring techniques. This is particular important for assessing residual and solubility trapping, which are more secure than structural trapping of free-phase CO2. It is difficult to quantify how much CO2 is stored by residual and solubility trapping across an entire storage site. Hence, there is a need to develop a test which can be performed at a single injection well during assessment of a potential site for CO2 injection. CO2CRC, one of the world-leading CCS research organisations, conducted the Otway Stage 2B Extension residual saturation test in December 2014 to determine residual trapping at their Otway test site in Victoria, Australia, using a single-well field setting. In direct collaboration with CO2CRC and other global research institutions (CSIRO Energy, University of Melbourne, Simon Fraser University, Lawrence Berkeley National Laboratory), we use water and gas geochemistry to establish the fate of CO2 injected into the Paaratte Formation at the Otway test site. More specifically, we study the application of oxygen isotopes and noble gases to reconstruct levels of residual trapping of CO2.

This poster on the UKCCSRC Call 1 project Chemical looping for low-cost oxygen production and other applications was presented at the CSLF Call project poster reception, London, 27.06.15. Grant number: UKCCSRC-C1-39. The project is based on the concept of CLOU (chemical looping oxygen uncoupling). Various forms of chemical looping are possible with different degrees of integration between the oxygen release and the thermal energy production cycles. • Most of the CLC and CLOU processes proposed thus far are conducted in a fluidised bed reactor encountering problems of contamination of the oxygen carrier and fuel leakage. • The project has designed a hybrid form of chemical looping that achieves the optimal degree of integration of oxygen release and thermal energy production. • The need for intimate contact between the oxygen carrier and the solid fuel is also avoided.

This poster on the UKCCSRC Call 1 project Tractable equations of state for CO2 mixtures in CCS was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-22. A potential bottle-neck for CCS is the transport of CO2 from power plants to the storage location, by pipeline. Key to safe and inexpensive transport is a detailed understanding of the physical properties of carbon dioxide. However, no gas separation process is 100% efficient, and the resulting carbon dioxide contains a number of different impurities. These impurities can greatly influence the physical properties of the fluid compared to pure CO2. They have important design, safety and cost implications for the compression and transport of carbon dioxide. This project aimed to develop new methods to produce custom models (equations of state) for impure CO2 behaviour for CCS.

This poster on the UKCCSRC Call 1 project Flexible CCS Network Development (FleCCSnet) was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-40. The aim of the project was to carry out research to enable the production of design and operating guidelines for CCS pipeline networks in order that these networks can react effectively to short, medium and long term variations in the availability and flow of CO2 from capture plants and also to the constraints imposed on the system by the ability (or otherwise) of CO2 storage facilities to accept variable flow. The amount of CO2 captured at a power station is expected to become more variable in the future as the electricity grid brings in more and more intermittent renewable energy (meaning a conventional power station is temporarily not needed or in reduced operation as the renewable energy takes precedent). The storage site will also face periods of maintenance which will impose constraints on the flow into the store and it is also important to look at the case of upset conditions in order to be able to predict any potential problems. Solutions to these all these issues need to be factored into the design of the CCS network, the focus of the project was to identify the issues surrounding flexibility and explore some of them.
