UKCCSRC Call 2 project poster: Measurement of Water Solubility Limits of CO2 Mixtures to Underpin the Safe Pipeline Transportation of CO2, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 2 project Measurement of Water Solubility Limits of CO2 Mixtures to Underpin the Safe Pipeline Transportation of CO2 was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-185. Monitoring the composition of mixtures which are of relevance to Carbon Capture and Storage pipelines is of high importance for the safe transportation of CO2 during the CCS process. Captured CO2 will contain varying amounts of impurities such as N2, H2, O2 and H2O. These are components which greatly affect the phase behaviour of the captured CO2. Being able to quantifiably monitor the composition and components of CCS-relevant mixtures is key for (i) safety; (ii) determining standard operating conditions. This project, incorporating several novel techniques, have been used to measure: • The phase behaviour and thermodynamic properties of CO2 containing varying amounts of impurities in order to improve or validate existing models of CCS relevant gas mixtures. • The solubility of water in impure CO2 CCS mixtures.

UKCCSRC Call 2 project poster: The Development and Demonstration of Best Practice Guidelines for the Safe Start-up Injection of CO2, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 2 project The Development and Demonstration of Best Practice Guidelines for the Safe Start-up Injection of CO2 into Depleted Gas Fields was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-183. Highly-depleted gas fields represent prime potential targets for large-scale storage of captured CO2 emitted from industrial sources and fossil-fuel power plants. Given the potentially low reservoir pressures as well as the unique thermodynamic properties of CO2, especially in the presence of the various stream impurities, the injection process presents significant safety and operational challenges. In particular, the start-up injection leads to the following risks: &bullet; blockage due to hydrate and ice formation following the contact of the cold CO2 with the interstitial water around the wellbore; &bullet; thermal stress shocking of the wellbore casing steel, leading to its fracture and ultimately escape of CO2; &bullet; over-pressurisation accompanied by CO2 backflow into the injection system due to the violent evaporation of the superheated liquid CO2 upon entry into the wellbore.

UKCCSRC Call 2 project poster: Shelter and Escape in the Event of a Release of CO2 from CCS Infrastructure (S-CAPE), CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 2 project Shelter and Escape in the Event of a Release of CO2 from CCS Infrastructure (S-CAPE) was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-179. Pipelines are acknowledged as one of the most efficient and cost-effective methods for transporting large volumes of various fluids over long distances and therefore the majority of proposed schemes for Carbon Capture and Storage (CCS) involve high pressure pipelines transporting CO2. In order to manage the risk in the event of the failure of a carbon dioxide (CO2) pipeline, it is a core requirement that a separation distance between pipelines and habitable dwellings is defined to ensure a consistent level of risk. The aim of this project is to develop validated and computationally efficient shelter and escape models describing the consequences to the surrounding population of a CO2 release from CCS transportation infrastructure. The models will allow pipeline operators, regulators and standard setters to make informed and appropriate decisions regarding pipeline safety and emergency response. This poster presents some preliminary findings from the S-Cape project and: &bullet; Describes the development of analytical and Computational Fluid Dynamic (CFD) models to calculate the change in internal CO2 concentration within a building engulfed by a dispersing cloud of CO2. &bullet; Investigates the sensitivity of the CO2 concentration within a building to wind speed and the temperature of the CO2 in the pipeline. &bullet; Demonstrates how CFD models can be used to verify results obtained using computationally efficient analytical models.

UKCCSRC Call 1 project poster: Flexible CCS Network Development (FleCCSnet), CSLF Call project poster reception, London, 27.06.16

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.

UKCCSRC Call 1 project poster: Chemical Looping for low-cost Oxygen Production, CSLF Call project poster reception, London, 27.06.16

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.

UKCCSRC Call 1 project poster: Bio-CAP-UK: Air/oxy biomass combustion with CO2 capture technology, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project Bio-CAP-UK: Air/oxy biomass combustion with CO2 capture technology was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-38. Bio-CCS - bioenergy with carbon capture and storage - has the ability to achieve potential net negative CO2 emissions, vital for meeting legally binding and increasingly stringent emission targets and carbon budgets. Bio-CCS has a large and distinct potential for significantly lowering CO2 emissions from energy production; thus the key messages from this programme will have clear policy implications on decarbonisation strategies. The Bio-CAP-UK project aims to accelerate progress towards achieving operational excellence for flexible, efficient and environmentally sustainable bio-CCS thermal power plants by developing and assessing fundamental knowledge. This is being achieved through extensive multi-scale experimental work, including bench and pilot-plant tests, combined with system simulations, techno-economic analysis and life cycle studies. The programme focuses on comparing air-firing coupled with post-combustion carbon capture to oxy-fuel combustion.

UKCCSRC Call 1 project poster: QICS2 Scoping: Exploring the Viability and Scientific Opportunities of a Follow-On Project, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project QICS2 Scoping Project: Exploring the Viability and Scientific Opportunities of a Follow-On Marine Impact Project was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-31. The world's first sub-seabed CO2 release experiment was completed in 2014, offshore from Oban (Scotland). The project, known as QICS (Quantifying and Monitoring Potential Ecosystem Impacts of Geological Storage), mimicked the formation of a small-scale CO2 leak into sediments near the seabed. In 2012, CO2 was continuously injected into the sediments for 37 days, releasing a total of 4.2 tonnes of CO2. The QICS1 experiment was first of its kind, and was highly successful, enabling: i. field testing of monitoring technologies to detect CO2 against a measured baseline ii. assessment of environmental and ecosystem impacts of leaked CO2 (within the sediment and water column) iii. the flow and fate of CO2 in sediments, and dispersion and dilution of CO2 in seawater, to be explored.

UKCCSRC Call 1 project poster: CO2 storage in Palaeogene and Neogene hydrogeological systems of the North Sea, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project CO2 storage in Palaeogene and Neogene hydrogeological systems of the North Sea: preparation of an IODP scientific drilling bid was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-30. The North Sea Basin (NSB) is considered to be suitable for commercial-scale CO2 storage, due to its favourable geological setting, its proximity to sources, and pioneering operational experience storing CO2 at the Sleipner injection site. The shallow Neogene and Quaternary sediments of the NSB form the overburden and seal to these underlying CO2 reservoirs but are under-researched, even though the NSB is a mature petroleum system, penetrated by many thousands of wells. Quaternary sediments, up to 1000 metres thick, are in general bypassed to reach the deeper, profitable hydrocarbon resources. UKCCSRC and CLIMIT programme funded scientific, governmental and industrial partners from the UK and Norway to collaborate with the purpose of submitting a proposal to the International Ocean Discovery Program (IODP) for scientific drilling to investigate the overburden to CO2 storage strata.

UKCCSRC Call 1 project poster: Experimental investigation and CFD modelling of oxy-coal combustion, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project Experimental investigation with PACT facility and CFD modelling of oxy-coal combustion with recycling real flue gas was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-27. Oxy-coal combustion technology has gained confidence and maturity especially within the last decade (Santos S. 2012) compared to the much earlier studies (Kimura et al., 1995; Wang et al., 1988). However, there are still a number of research challenges associated with flue gas recycling, gas clean-up and plant scale tools and models. Flue gas recycling affects the purity of CO2, oxygen mixing, and ignition of coal particles and flame stability. There is lack of experimental data with real flue gas recycling or treated vent gas recycling, which is one of the available options to achieve the target of zero emissions (Hack et al., 2011), at pilot-scale for the validation of CFD models. The project focuses on the following tasks: • Experimental investigation of oxy-coal combustion, ignition and flame stability with the 250kWth PACT Oxy-Coal Combustion furnace with real and simulated flue gas recycling • Experimental investigation of oxy-coal combustion ignition and flame stability with a laboratory visual drop tube furnace • CFD simulation of the 250kWth PACT Oxy-coal combustion furnace.

UKCCSRC Call 1 project poster: Mixed matrix membranes for post-combustion carbon capture, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project Mixed matrix membranes for post-combustion carbon capture was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-19. &bullet; This work aims to develop an understanding of the gas transport mechanisms within mixed matrix membranes focussing on membranes for post-combustion carbon capture. &bullet; Separation of carbon dioxide from combustion flue gases using selective membranes shows promise to be a low energy carbon capture option and is proven as a commercially viable gas separation technology. &bullet; Membranes potentially offer significant energy savings over the currently more developed amine-based absorption technologies. &bullet; Mixed matrix membranes (MMMs) are composite materials comprised of particulate fillers in a polymeric matrix. &bullet; Polymer membranes exhibit a trade-off between permeability and selectivity. By adding fillers the gas separation properties of the membrane can be altered and improved. &bullet; MMMs are fabricated from various materials and the gas permeation properties tested such that the interaction of phases can be investigated.

UKCCSRC Call 1 project poster: Oxyfuel and EGR Processes in GT Combustion, CSLF Call project poster reception, London, 27.06.16

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. &bullet; The use of CO2 as a combustion diluent. &bullet; Potential for CO emission into the capture plant. &bullet; Wide or variable operating envelopes across diluent concentrations. &bullet; Differences in the properties of N2 and CO2 giving rise to previously unmeasured flame heat release locations.

UKCCSRC Call 1 project poster: Tractable equations of state for CO2 mixtures in CCS, CSLF Call project poster reception, London, 27.06.16

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.

UKCCSRC Call 1 project poster: Determination of water Solubility in CO2 Mixtures, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project Determination of water solubility limits in CO2 mixtures to deliver water specification levels for CO2 transportation was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-21. Studies of the phase behaviour and water solubility of pure and impure CO2 are of great relevance to the transport phase of the carbon capture and storage (CCS) process. For transport through carbon steel pipelines, CO2 and any impurities present must be present as a single phase to avoid corrosion, and subsequent loss of pipeline integrity. Trace impurities such as H2 and N2 have been shown to alter the phase behaviour of the CO2 at high pressure. Understanding the effect of these impurities on the solubility of H2O in CO2 is vital to confirm the safety and viability of CO2 transport through carbon steel pipelines.

UKCCSRC Call 1 project poster: 3D Mapping of Large-Scale Subsurface Flow Pathways using Nanoseismic Monitoring, CSLF Call project poster reception, London, 27.06.16

This poster on the UKCCSRC Call 1 project 3D Mapping of Large-Scale Subsurface Flow Pathways using Nanoseismic Monitoring was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-19. Injection of fluids into geological formations induces microseismic events due to pressure changes causing either opening mode or shear mode fracturing. Injection for CO2 storage is designed to be well below the pressures required for hydraulic fracturing. Due to the inherent heterogeneity of geological formations, some existing structures will be critically stressed so small microseismic events are inevitable. Current reservoir monitoring strategies either examine time-lapse variations in the rock’s elastic properties (4D seismic) over diffuse areas, or aim to detect leakage from diffuse and point sources at the seabed (e.g. the QICS project). The aim of the project is twofold: &bullet; test the potential of a new technology (nanoseismics) for passive seismic monitoring that aims to image focused flow pathways at depth of an active CO2 injection site: the Aquistore site, Canada; &bullet; use a multi-disciplinary approach to interpret passive seismic data sets obtained during operation of the same site.

Predictive Seabed Sediments UK v1

The BGS Predictive Seabed Sediments UK v1 dataset includes digital maps of seabed sediment (SBS) composition across the UK Continental Shelf (UKCS). The dataset includes one classified SBS map (Folk sediment class; vector), and three percentage-sediment maps (rasters) giving the proportions of gravel, sand, and mud. The dataset is generated using a machine learning algorithm known as a Distributional Random Forest (DRF). The model uses input data to predictively classify what seabed sediments are most likely to be the dominant sediment present. It does so, using more than 38,000 seabed sediment samples (collated from various sources) with measurements of the proportion of mud, sand and gravel from locations across the study area. The predictions are constrained against covariate variables that are known to influence which sediment is most likely to occur. These include bathymetry data morphometric derivatives (at multiple spatial scales), as well as hydrodynamic data layers (currents and tidal). The dataset was reviewed via a qualitative assessment (QA) protocol by subject-area experts (e.g. contrasting with previous mapping, and local examples of higher-resolution data and mapping), and following methodological improvements based on this feedback, updated SBS map products were prepared. The dataset is presented at a national-scale, with a spatial resolution of approximately 110m, covering the UKCS (slightly modified UKCS area based on data availability).
