Abstract
Current
research aims to find ways to use the direct and catalyzed electrochemistry of
CO2 to reduce the inert molecule to fuels by means of solar energy. This may be
direct, after conversion of light to electricity, or indirect in that all
elements derived from electrochemical experiments can be used in the design and
interpretation of photochemical experiments.
Authors review recent findings which make it possible to analyze and
compare the performances of existing catalysts when the necessary data are
available. Among the general trends that transpire presently and are likely to
be the object of active future work emphasis is put on the favorable role of
acid addition in homogeneous catalytic systems and on the crucial chemical role
of the electrode material in heterogeneous catalysis.

Abstract
Several recent life cycle assessment (LCA) studies have calculated GHG emissions from oil sands extraction, upgrading, and refining pathways. The results from these studies are quite varied. Authors review factors affecting energy consumption and GHG emissions from oil sands extraction.
They then use publicly available data to analyze the assumptions made in the LCA models to better understand the causes of variability in emissions estimates. They find that the variation in oil sands GHG estimates is due to a variety of causes. They include scope of modeling and choice of projects analyzed; differences in assumed energy intensities of extraction and upgrading; differences in the fuel mix assumptions; treatment of secondary noncombustion emissions sources, such as venting, flaring, and fugitive emissions; and treatment of ecological emissions sources, such as land-use change-associated emissions. Authors recommend the GHGenius model as the LCA model that is most congruent with reported industry average data.

Design and Analysis of CO2 Capture, Transport, and Storage Networks
CATEGORY: CCS – CARBON CAPTURE & STORAGE
Carbon Management Technology Conference, 7-9 February 2012, Orlando, Florida, USA
Design and Analysis of CO2 Capture, Transport, and Storage Networks
Ahmed Alhajaj, and Nilay Shah, Imperial College London
Abstract
The large-scale deployment of carbon capture, transport and storage (CCTS) systems will be capital intensive and complex. Accordingly, it is necessary to design a network infrastructure that can meet a specific CO2 reduction target and is at the same time optimized to minimize cost and operation problems. Authors present a multiscale modeling approach using flue gas characterization data as an input to simulate and size a post-combustion capture plant model.
They use the profile of the bare capturing cost of CO2 against degree of capture to design and analyze the cost optimal CO2 infrastructure layout that matches CO2 sources and sinks in capacity and time. This helps generate insights of whole-system integration issues and its performance as function of design variables. Consequently, the whole system is optimized rather than optimizing individual components, which leads to sup-optimal CCTS design.

Development of a CO2 network for industrial emissions
Dermot J. Roddy,
Science City Professor of Energy, Newcastle University, Newcastle-upon-Tyne NE1 7RU, UK
Abstract
The application of Carbon Capture and Storage (CCS) technology to energy-intensive processes is starting to attract attention, which creates opportunities for the development of multi-user CO2 transportation networks.
Because most industrial facilities have not been designed with CCS in mind, the author begins by looking at the practical issues associated with retrofitting CCS to industrial facilities. He then explores the technical and legal issues associated with building a CO2 network. He follows this with an analysis of the costs involved. Having identified the key issues, he presents a case study from North East England as an example of what is possible in an area of high CO2 emissions.

Wrocław University of Technology, Wybrzeże Wyspiańskiego 27, 50-370 Wrocław, Poland
Abstract
Carbon-based energy vectors can use existing energy infrastructures and can serve all energy applications including transport.
Author reviews how carbon-based energy vectors can be made suitable for design of low CO2 intensive and cost-effective energy systems. He describes several carbon management technologies which integrate and add value to energy technologies.
His analysis shows that energy systems involving carbon-based vectors can achieve very low CO2 intensity when they use an energy mix of carbon positive and carbon negative technologies. Opportunities for integration of value-added carbon management technologies into fossil fuel, biomass and renewable energy technologies are discussed.

b Division of Energy Technology, Department of Energy and Environment, Chalmers University of Technology, SE-412 96 Göteborg, Sweden
Abstract
Authors describe the European petroleum refining industry and the prospects for future CO2 abatement in relation to associated infrastructure. A more efficient use of the adjacent infrastructure, e.g., district heating networks, natural gas grids, neighbouring industries, and CO2 transport and storage systems, could provide opportunities for additional CO2 emissions reduction.
Access to infrastructures that can facilitate CO2 abatement varies significantly across countries and between individual refineries. Short-term mitigation option could reduce CO2 emissions by 9–40 MtCO2/year. Carbon capture and storage offers the greatest potential for more significant emission reductions in the longer term. However, the potential for CO2 capture varies significantly depending on the choice of technology, CO2 source, and scope of implementation.

Abstract
Evaluates the opportunities and associated costs for post-combustion capture at a world-scale complex refinery.
Results indicate that it is technically feasible to apply post-combustion capture at such a refinery.
However, cost considerations indicate that justification of the implementation of post-combustion capture at refineries requires, either a significant increase in carbon trading values, mandatory regulations, or a major technological break-through.

Abstract
Although Carbon Capture and Storage (CCS) technologies are being developed with the focus of capturing and storing CO2 in huge quantities, new methods for the chemical exploitation of carbon dioxide (CCU) are being developed in parallel.
The intensified chemical or physical utilization of CO2 is targeted at generating value from a limited part of the CO2 stream and developing better and more efficient chemical processes with reduced CO2 footprint. Authors compare the status of the three main lines of CCS technologies with respect to efficiency, energy consumption, and technical feasibility as well as the implications of CCS on the efficiency and structure of the energy supply chain.

Abstract
Presents pioneering on-line emission data from a PCCC (post combustion carboncapture) pilot plant of both inorganic and organic components measured using an extractive FTIR (Fourier Transform Infra Red) system.
A comparison with other emission measurements allowed concluding that the system is suitable as research tool for investigating the effect of PCCC operational settings on amine emissions. It also showed that sampling and analysing single organic components in flue gases is difficult and more research is needed on this topic. Linking the operational data of the plant with the on-line emission data identified two important operational settings that control the amine emissions from a PCCC plant to a large extent.
The study emphasizes the importance of a well-designed washing section which will be able to reduce emissions to very low levels keeping in mind the lessons learned in this study with respect to its operational settings.

Abstract
The rheological properties of heavycrude oil and its mixture with light crude oil were investigated experimentally.
From the comparison of the storage and loss moduli values for the heavycrude oil, it is found that the heavycrude and its blends flow in a viscous liquid behavior. The 10% and 20% of the HLCO mixtures display viscous behavior as well. The storage and loss moduli of the heavycrude oil decrease significantly by the addition of 10% light crude oil.

Abstract
Investigates the potential of microorganisms for enhancing carbon capture and storage (CCS) via mineral-trapping and solubility trapping. The bacterial hydrolysis of urea (ureolysis) was investigated in microcosms including synthetic brine (SB) mimicking a prospective deep subsurface CCS site with variable headspace pressures [p(CO2)] of 13C-CO2.
Modeling the change in brine chemistry and carbonate precipitation after equilibration with the initial p(CO2) demonstrated that no net precipitation of CO2(g) via mineral-trapping occurred, since urea hydrolysis results in the production of dissolved inorganic carbon. However, the pH increase induced by bacterial ureolysis generated a net flux of CO2(g) into the brine. This reduced the headspace concentration of CO2 by up to 32 mM per 100 mM urea hydrolyzed because the capacity of the brine for carbonate ions was increased, thus enhancing the solubility-trapping capacity of the brine.

In addition, the AHA IL viscosity is predicted to be insensitive to CO2. The results demonstrate the intrinsic design advantages of ILs as a platform for CO2 separations.

Abstract
Evaluates the opportunities and associated costs for post-combustion capture at a world-scale complex refinery.
Authors conclude that it is technically feasible to apply post-combustion capture at such a refinery. Our evaluations show the costs of capture from such sources based on available amine technology will be in the range of 90–120 Euro per ton, 3–4 times higher than current carbon trading values. The capture of CO2 from a large amount of smaller CO2 sources will bring along even higher costs. Study results illustrate that, for the justification of the implementation of post-combustion capture at refineries, either a significant increase in carbon trading values, mandatory regulations, or a major technological break-through is required.

Abstract
Describes an indirect mineral carbonation process which could mitigate anthropogenic CO2 emissions.
In the process, magnesium silicate is dissolved in HCl and the resulting MgCl2 solution is subsequently reacted with CO2 in NH3. HCl and NH3 are recovered from NH4Cl in a two-step thermal decomposition. Carbonation is investigated from 30°C to 180°C at 4MPa CO2 pressure and Mg-carbonate morphology transformations with increasing temperature are identified.

Abstract
Describes field tests of a carbon filter that selectively captures CO2 from flue gas on porous carbonaceous sorbents.
A new sorbent regeneration process, referred to as steam-aided vacuum swing adsorption (SA-VSA), uses steam under vacuum to displace CO2 from the carbon. Over 100 sorption–desorption cycles on flue gas produced in the lab and at two coal-fired power plants demonstrate that the SA-VSA-equipped carbon filter process can produce a nearly pure CO2 product (at least 98%) while achieving high recovery (at least 98%). While stable, flexible, and robust in achieving the very high recovery and purity targets, this technology offers ample room for improvement through process optimization and, especially, sorbent optimization. For one of the reasonable but arbitrarily selected and inexpensive sorbents, a preliminary cost estimate example suggests an energy penalty of 31%.

Aquistore: A fully integrated demonstration of the capture, transportation and geologic storage of CO2

Abstract
Aquistore is an integrated carbon capture-geologic storage project that will demonstrate the effectiveness of the CCS process, and will ultimately transition into a commercial operation. Initially about 550 tonnes/day of CO2 will be captured from a steam methane reformer associated with the Consumers’ Co-operative Refineries Limited’s refinery in, Regina, Saskatchewan, Canada using an amine based process starting late 2012 to 2013.
Capture will be increased to near 1600 tonnes/day CO2 by introducing capture to a second SMR in subsequent years. A 5 to 10 km pipeline will be constructed to transport the compressed CO2 to the injection location. Selection of the injection site location is based primarily on geological characteristics, proximity to the CO2 source, ease of pipeline routing, and availability of rights to the subsurface. In Saskatchewan, current regulations around injecting and storing CO2 in the subsurface fall under the Oil and Gas Conservation Act, and injection of CO2 requires a lease of pore space on Crown Land, or an agreement with the Freehold Rights owner. A significant research component is associated with this project coordinated by a Science and Engineering Research Committee that has focused on assessing injectivity, capacity and containment. A static geologic model for the proposed injection site integrates available geological data and forms the basis for flow simulations to model plume distribution. The nearest existing well to the proposed injection site that penetrates to the injection unit is about 20 km away, and was extensively cored and logged and serves as a preliminary data well for reservoir mineralogy and petrophysical characteristics.

Abstract
Author describes the practical issues related to retrofitting CCS to industrial facilities. He then explores the technical and legal issues associated with building a CO2 network.
Author then analyzes the costs involved in forming a network. He presents a case study from North East England as an example of what is possible in an area of high CO2 emissions. The paper concludes by considering the issues involved in sizing a CO2 network which can evolve to meet future needs and linking that to the development of policy.
