Book Description
Nationally-recognised studies and our contacts with a diverse group of industry representatives, non-governmental organisations, and academic researchers show that key barriers to CCS deployment include (1) underdeveloped and costly CO2 capture technology and (2) regulatory and legal uncertainties over CO2 capture, injection, and storage. Among the key technological barriers are a lack of experience in capturing significant amounts of CO2 from power plants and the significant cost of capturing CO2, particularly from existing coal-fired power plants, which are the single largest source of CO2 emissions in the United States. Compounding these technological issues are regulatory and legal uncertainties, including uncertainty regarding liability for CO2 leakage and ownership of CO2 once injected. According to the IPCC, the National Academy of Sciences, and other knowledgeable authorities, another barrier is the absence of a national strategy to control CO2 emissions (emissions trading plan, CO2 emissions tax, or other mandatory control of CO2 emissions), without which the electric utility industry has little incentive to capture and store its CO2 emissions. Moreover, according to key agency officials, the absence of a national strategy has also deterred their agencies from addressing other important practical issues, such as resolving how stored CO2 would be treated in a future CO2 emissions trading plan.

Book Description
Any comprehensive approach to substantially reduce greenhouse gases must address the world's dependency on coal for a quarter of its energy demand, including almost half of its electricity demand. To maintain coal in the world's energy mix in a carbon-constrained future would require development of a technology to capture and store its carbon dioxide emissions. This situation suggests to some that any greenhouse gas reduction program be delayed until such carbon capture technology has been demonstrated. However, technological innovation and the demands of a carbon control regime are interlinked; a technology policy is no substitute for environmental policy and must be developed in concert with it. Much of the debate about developing and commercializing carbon capture technology has focused on the role of research, development, and deployment (technology-push mechanisms). However, for technology to be fully commercialized, it must also meet a market demand -- a demand created either through a price mechanism or a regulatory requirement (demand-pull mechanisms). Any conceivable carbon capture technology for coal-fired powerplants will increase the cost of electricity generation from affected plants because of efficiency losses. Therefore, few companies are likely to install such technology until they are required to, either by regulation or by a ...

Book Description
Any comprehensive approach to substantially reduce greenhouse gases must address the world's dependency on coal for a quarter of its energy demand, including almost half of its electricity demand. To maintain coal in the world's energy mix in a carbon-constrained future would require development of a technology to capture and store its carbon dioxide emissions. This situation suggests to some that any greenhouse gas reduction program be delayed until such carbon capture technology has been demonstrated. However, technological innovation and the demands of a carbon control regime are interlinked; a technology policy is no substitute for environmental policy and must be developed in concert with it. Much of the debate about developing and commercializing carbon capture technology has focused on the role of research, development, and deployment (technology-push mechanisms). However, for technology to be fully commercialized, it must also meet a market demand -- a demand created either through a price mechanism or a regulatory requirement (demand-pull mechanisms). Any conceivable carbon capture technology for coal-fired powerplants will increase the cost of electricity generation from affected plants because of efficiency losses. Therefore, few companies are likely to install such technology until they are required to, either by regulation or by a carbon price. Regulated industries may find their regulators reluctant to accept the risks and cost of installing technology that is not required. The Department of Energy (DOE) has invested millions of dollars since 1997 in carbon capture technology research and development (R & D), and the question remains whether it has been too much, too little, or about the right amount. In addition to appropriating funds each year for the DOE program, Congress supported R & D investment through provisions for loan guarantees and tax credits. Congress also authorized a significant expansion of carbon capture and sequestration (CCS) spending at DOE in the Energy Independence and Security Act of 2007. Legislation has also been introduced in the 110th Congress that would authorize spending for carbon capture technology development. Other legislation introduced invokes the symbolism of the Manhattan Project of the 1940s and the Apollo program of the 1960s to frame proposals for large-scale energy policy initiatives that include developing CCS technology. However, commercialization of technology and integration of technology into the private market were not goals of either the Manhattan Project or Apollo program. Finally, it should be noted that the status quo for coal with respect to climate change legislation isn't necessarily the same as "business as usual." The financial markets and regulatory authorities appear to be hedging their bets on the outcomes of any federal legislation with respect to greenhouse gas reductions, and becoming increasingly unwilling to accept the risk of a coal-fired power plant with or without carbon capture capacity. The lack of a regulatory scheme presents numerous risks to any research and development effort designed to develop carbon capture technology. Ultimately, it also presents a risk to the future of coal.

Book Description
Absorption-Based Post-Combustion Capture of Carbon Dioxide provides a comprehensive and authoritative review of the use of absorbents for post-combustion capture of carbon dioxide. As fossil fuel-based power generation technologies are likely to remain key in the future, at least in the short- and medium-term, carbon capture and storage will be a critical greenhouse gas reduction technique. Post-combustion capture involves the removal of carbon dioxide from flue gases after fuel combustion, meaning that carbon dioxide can then be compressed and cooled to form a safely transportable liquid that can be stored underground. - Provides researchers in academia and industry with an authoritative overview of the amine-based methods for carbon dioxide capture from flue gases and related processes - Editors and contributors are well known experts in the field - Presents the first book on this specific topic

Book Description
To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Book Description
Carbon Capture and Storage is a key technology for a sustainable and low carbon economy. This book unites top academic and industry researchers in search for commercial concepts for CCS at coal power ploants. This reference focuses on power plant technology and ways to improve efficiency. It details the three principal ways of capturing the CO2 produced in power plants: oxyfuel combustion, postcombustion and precombustion, with the main part concentrating on the different approaches to removing carbon dioxide. Wtih an eye on safety, the authors explain how the three parts of the CCS chain work - capture, transport and storage - and how they can be performed safely. The result is specific insights for process engineers, chemists, physicists and materials engineers in their relevant fields, as well as a sufficiently broad scope to be able to understand the opportunities and implications of the other disciples.

Book Description
Legislation introduced in the 111th and 110th Congresses invokes the symbolism of the Manhattan project of the 1940s and the Apollo program of the 1960s to frame proposals for large-scale energy policy initiatives that include developing CCS technology. [...] Arguably the most economic and technologically challenging part of the carbon capture and sequestration (CCS) equation is capturing the carbon and preparing it for transport and storage.5 Depending on site-specific conditions, the capture component of a CCS system can be the dominant cost-variable, and the component that could be improved most dramatically by further technological advancement. [...] Second, the paper examines the role of government in developing that technology, both in terms of creating a market for carbon capture technology and encouraging development of the technology. [...] A recent study by the Massachusetts Institute of Technology (MIT) estimated the efficiency losses from the installation of MEA from 25%-28% for new construction and 36%- 42% for retrofit on an existing plant.9 This loss of efficiency comes in addition to the necessary capital and operations and maintenance cost of the equipment and reagents. [...] The details of this "oxy-fuel" process are still being refined, but generally, from the boiler the exhaust gas is cleaned of conventional pollutants (SO2, NOx, and particulates) and some of the gases recycled to the boiler to control the higher temperature resulting from coal combustion with pure oxygen.

Book Description
On March 27, 2012, the U.S. Environmental Protection Agency (EPA) proposed a new rule that would limit emissions to no more than 1,000 pounds of carbon dioxide (CO2) per megawatt-hour of production from new fossil-fuel power plants with a capacity of 25 megawatts or larger. EPA proposed the rule under Section 111 of the Clean Air Act. According to EPA, new natural gas fired combined-cycle power plants should be able to meet the proposed standards without additional cost. However, new coal-fired plants would only be able to meet the standards by installing carbon capture and sequestration (CCS) technology. The proposed rule has sparked increased scrutiny of the future of CCS as a viable technology for reducing CO2 emissions from coal-fired power plants. The proposed rule also places a new focus on whether the U.S. Department of Energy's (DOE's) CCS research, development, and demonstration (RD&D) program will achieve its vision of developing an advanced CCS technology portfolio ready by 2020 for large-scale CCS deployment. Congress has appropriated nearly $6 billion since FY2008 for CCS RD&D at DOE's Office of Fossil Energy: approximately $2.3 billion from annual appropriations and $3.4 billion from the American Recovery and Reinvestment Act (or Recovery Act). The large and rapid influx of funding for industrial-scale CCS projects from the Recovery Act may accelerate development and deployment of CCS in the United States. However, the future deployment of CCS may take a different course if the major components of the DOE program follow a path similar to DOE's flagship CCS demonstration project, FutureGen, which has experienced delays and multiple changes of scope and design since its inception in 2003. A question for Congress is whether FutureGen represents a unique case of a first mover in a complex, expensive, and technically challenging endeavor, or whether it indicates the likely path for all large CCS demonstration projects once they move past the planning stage. Since enactment of the Recovery Act, DOE has shifted its RD&D emphasis to the demonstration phase of carbon capture technology. The shift appears to heed recommendations from many experts who called for large, industrial-scale carbon capture demonstration projects (e.g., 1 million tons of CO2 captured per year). Funding from the Recovery Act for large-scale demonstration projects was 40% of the total amount of DOE funding for all CCS RD&D from FY2008 through FY2012. To date, there are no commercial ventures in the United States that capture, transport, and inject industrial-scale quantities of CO2 solely for the purposes of carbon sequestration. However, CCS RD&D in 2012 is just now embarking on commercial-scale demonstration projects for CO2 capture, injection, and storage. The success of these projects will likely bear heavily on the future outlook for widespread deployment of CCS technologies as a strategy for preventing large quantities of CO2 from reaching the atmosphere while U.S. power plants continue to burn fossil fuels, mainly coal. Given the pending EPA rule, congressional interest in the future of coal as a domestic energy source appears directly linked to the future of CCS. In the short term, congressional support for building new coal-fired power plants could be expressed through legislative action to modify or block the proposed EPA rule. Alternatively, congressional oversight of the CCS RD&D program could help inform decisions about the level of support for the program and help Congress gauge whether it is on track to meet its goals.
