This poster on the UKCCSRC Call 2 project Novel reductive rejuvenation approaches for degraded amine solutions from PCC in power plants was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-189. Aqueous amine scrubbing is currently considered to be the best available technology of carbon capture for both pulverised fuel and natural gas power plants. A major problem is the thermo-oxidative degradation of chemical amine solvents used, leading to a range of operational problems and the generation of large quantities of hazardous aqueous waste. However, no existing technologies are able to effectively deal with these problems particularly the handling of the toxic waste solvent streams. The conversion of the degraded amines back to usable solvents or saleable products has been regarded as a novel effective way for cost reduction.

This poster on the UKCCSRC Call 1 project Oxyfuel and exhaust gas recirculation processes in gas turbine combustion for improved carbon capture performance was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-26. This research is concerned with oxyfuel combustion in gas turbine applications, in particular concentrating on the use of modern swirl-stabilised burners. Oxyfuel is considered a particularly challenging idea, since the resultant burning velocity and flame temperatures will be significantly higher than what might be deemed as a practical or workable technology. For this reason it is widely accepted that EGR-derived CO2 will be used as a diluent and moderator for the reaction (in essence replacing the role of atmospheric nitrogen). The key challenges in developing oxyfuel gas turbine technology are therefore: • Flame stability at high temperatures and burning rates. • The use of CO2 as a combustion diluent. • Potential for CO emission into the capture plant. • Wide or variable operating envelopes across diluent concentrations. • Differences in the properties of N2 and CO2 giving rise to previously unmeasured flame heat release locations.

This report has been superseded by the paper: https://www.sciencedirect.com/science/article/pii/S1750583617301081. Grant number: UKCCSRC-C1-31. The NERC-funded QICS controlled CO2 release experiment (located offshore Oban, Scotland) mimics the formation of a new CO2 seep in the marine environment. At the site, CO2 is injected at an onshore well head, and a stainless steel pipe transports the CO2 under the seabed. Approximately 350 m offshore, the CO2 is released through a perforated screen into the 12 metres of overlying marine sediment, which is at approximately 10 metres water depth. During spring/summer 2012, 4.2 tonnes of CO2 was released at the QICS experimental site. A key element of risk assessment for the subsurface storage of CO2 is the monitoring of leaks from the subsurface in to the marine or terrestrial environments via sediments and soils. Chemical 'fingerprinting' of injected CO2 is widely considered a low cost, highly effective monitoring option, since effective application of tracers in CCS could provide information on (i) the movement, interaction and fate of injected CO2 in the subsurface and (ii) the detection (and quantification) of CO2 that has leaked from the storage complex to the surface. There is a need to develop geochemical techniques to differentiate between CO2 from natural processes, and the QICS site may provide excellent opportunity to trial geochemical tracers. This work aims to determine which chemical tracers are most suitable for CO2 tracing at the QICS facility and the research questions that tracer application can address. As such, this report includes: i. A review of current potential chemical tracers for CCS and their applications. ii. An analysis and comparison of costs, availability, environmental impact and detection limits for potential tracers. iii. An assessment of the above in the context of QICS (i.e: considering the CO2 will be released from the seabed (having passed from dense to gas phase), and having passed through water saturated sediment of the seabed, and into the water column. iv. An overview of the legal considerations for tracers in the UK. v. The injection method for tracers at the QICS site. vi. Required strategies for sampling the selected tracer. vii. Identify knowledge gaps in tracer studies which experiments at the QICS site could address.

This poster on the UKCCSRC Call 2 project Multiscale Characterisation of CO2 Storage in the United Kingdom was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-197. We combine pore scale digital rock physics, reservoir condition special core analysis, and reservoir simulation to evaluate the performance of CO2 storage for the major target storage regions of the UK. Key objectives: • Develop a dataset of relative permeability and residual trapping for major storage targets in the UK (Fig. 1), obtained experimentally at reservoir conditions • Identify the contribution of pore scale rock morphology to multiphase flow dynamics and dissolution trapping • Use the data in reservoir simulations to update dynamic capacity estimation for UK reservoirs
