This book was released on 2020-04-13 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal production, transportation, storage and use account for roughly 40% of global greenhouse gas emissions. Methane, which is a potent greenhouse gas with a 100-year global warming potential 25 times that of carbon dioxide (CO2) and a 100-year global temperature potential 6-fold greater than CO2, once released from coal seams in which it is trapped creates number of problems even after cessation of mining activities. Following mine closure, methane emissions decrease, but do not stop completely. They initially decline, but can later stabilize and maintain a near-constant rate for an extended period of time. The document presents recommended principles and standards for effective methane recovery and use from abandoned coal mines in a clear and succinct way, providing decision-makers with a solid base of understanding from which to direct policy and commercial decisions. The Best Practice Guidance does not replace or supersede laws and regulations or other legally binding instruments, whether national or international. The principles outlined therein are intended to complement existing legal and regulatory frameworks and to support development of safer and more effective practices where industry practice and regulation continue to evolve. At the same time, being envisioned primarily as a tool to support performance- and principle-based regulatory programmes, the Best Practice Guidance can also complement more prescriptive regulation and support transition to performance-based regulation.

This book was released on 2016 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today coal supplies around 30 per cent of global primary energy and 40 per cent of global electricity. Coal extraction has become increasingly challenging as shallow reserves are exhausted and deeper seams, with significant content of methane, are mined. Societies are demanding and expecting safer mine working conditions, and greater environmental stewardship from the coal industry. The global coal industry, national governments, trade unions, and worker safety advocates are concerned that the frequency and severity of methane explosions, especially in emerging economies, are unacceptably high. Coal mine methane (CMM) only becomes flammable and creates an explosion hazard when allowed to mix with air. Methane-rich gases, generally containing 80 per cent to 95 per cent methane at underground mining depths, occur naturally in coal seams and are released as CMM when coal seams are disturbed by mining activities. Methane is an explosive gas in the range of 5 per cent to 15 per cent methane in air. The application of best practices for methane drainage and use is critical to reduce methane-related accidents and explosions that all too often accompany coal mining, while also contributing to environmental protection through reduction of greenhouse gas (GHG) emissions. Good mining practices need to be transferred to all countries to ensure that risks are managed professionally and effectively. No mine, even in the most developed countries, is free from safety risks. Regardless of location or mining conditions, it is possible to significantly reduce the risk of methane related incidents and explosions. Good safety practice in coal mines is to reduce explosion risk by preventing the occurrence of explosive mixtures and, where practical, by monitoring and rapidly diluting explosive mixtures to safe concentrations.

This book was released on 2013-03-09 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.

This book was released on 2022-04 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: While Methane (CH4) is the second most prevalent anthropogenic greenhouse gas (GHG) after carbon dioxide (CO2), the Global Warming Potential (GWP) of the former is 28-34 times higher than that of the latter. Coal mining is a major source of methane emissions, accounting for about 12% of global total anthropogenic emissions of that gas. Most emissions come from underground working mines, but those from abandoned mines are raising. Action on methane requires a solid understanding of emission sources at national, subnational, and local levels. Only with reliable emissions data, can policymakers design effective GHG policies, evaluate mitigation opportunities, and comply with their international climate commitments. National monitoring, reporting, and verification (MRV) programs can not only help countries better understand the contribution of coal mining to their overall methane and GHG emissions, but also identify opportunities for mitigation. In particular, MRV can help assess and track the effectiveness of the adopted climate policies. Setting up efficient MRV schemes is also important to deliver on international climate commitments in the context of the Paris Agreement.

Book excerpt: Research on climate change has identified a wide array of sources that emit greenhouse gases (GHGs). Among the 6 gases that have been the primary focus of concern, methane is the second-most abundant, accounting for approximately 8% of total U.S. GHG emissions in 2008. Methane is emitted from a number of sources. The most significant are agriculture (both animal digestive systems and manure management); landfills; oil and gas production, refining, and distribution; and coal mining. This report discusses alternatives for addressing methane capture, sources of methane, opportunities and challenges for methane capture, and current federal programs that support methane recovery.

Available in PDF, EPUB and Kindle. Book excerpt: Global fugitive methane emissions from coal sector accounts for 8 % annually of global methane emissions from human activities, representing the loss of a valuable energy resource. Coal mine methane recovery and use represents a cost-effective means of significantly reducing methane emissions from coal mining, while increasing mine safety and improving mine economics. The world's ten largest coal producers, including Poland, are responsible for 90% of global methane emissions. Poland's methane emissions from coal mining contribute a large percent to the global as well as country's total greenhouse gas emissions. This publication provides information concerning methane recovery technologies as well as the potential for expanding coal mine methane recovery in Poland.

This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is a short-lived greenhouse gas that is released during the production and transport of coal, natural gas, and oil; the raising of livestock and other agricultural practices; and the decay of organic waste in municipal solid waste landfills and some wastewater treatment systems. Although it is short-lived, methane has more than 20 times the atmospheric warming effect of carbon dioxide. However, it is a primary component of natural gas, so efforts to reduce methane emissions can take advantage of technologies that capture and reuse the gas as a fuel, potentially bringing about cost-effective reductions in emissions. The Global Methane Initiative (GMI) is a voluntary international partnership that promotes methane recovery and reuse activities in developing and transition economies. Program partners and funders include national governments, private-sector firms, development banks, and nongovernmental organizations. As a founding member of the partnership, the U.S. government contributes funding and other types of support to GMI primarily through the U.S. Department of State (specifically, its Bureau of Oceans and International Environmental and Scientific Affairs and its Office of Global Change) and the U.S. Environmental Protection Agency. To help gauge the effects and value added of its support for the program, the Department of State requested an evaluation of GMI's activities and outcomes relative to its contributions in fiscal years 2006-2010. The evaluation employed a mixed-methods approach that combined quantitative and qualitative information to document program resources and activities and to illustrate program outcomes, including information from in-country site visits. The report also presents some recommendations for how data collection could be improved to answer more sophisticated questions in the future about the effectiveness of GMI and the value added by the department's contributions.

This book was released on 1980 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the activity in the private sector of the United States regarding removal and utilization of coalbed methane, an attempt was made to learn to what extent and for what purposes coalbed methane is currently being used, what experimental programs exist, and what programs are planned or proposed. Information presented in this report was obtained primarily from interviews with coal industry personnel familiar with the subject of recovery of methane from coalbeds. Methods presently used or under investigation in the United States for removing methane from coalbeds are briefly described, and factors to consider when planning methane removal are presented. The study identifies various obstacles that must be overcome for methane removal techniques to become routine procedures and for the methane capture to become attractive as a fuel. It proposes R & D and other measures to address these obstacles and eventually permit the economic recovery of coalbed methane and the conservation of a non-renewable energy resource.

Download or read book The Economic Feasibility of Enhanced Coalbed Methane Recovery Using CO2 Sequestration in the San Juan Basin written by Angeni Agrawal and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide emissions are considered a major source of increased atmospheric CO2 levels leading towards global warming. CO2 sequestration in coal bed reservoirs is one technique that can reduce the concentration of CO2 in the air. In addition, due to the chemical and physical properties of carbon dioxide, CO2 sequestration is a potential option for substantially enhancing coal bed methane recovery (ECBM). The San Juan Fruitland coal has the most prolific coal seams in the United States. This basin was studied to investigate the potential of CO2 sequestration and ECBM. Primary recovery of methane is controversial ranging between 20-60% based on reservoir properties in coal bed reservoirs15. Using CO2 sequestration as a secondary recovery technique can enhance coal bed methane recovery up to 30%. Within the San Juan Basin, permeability ranges from 1 md to 100 md. The Fairway region is characterized with higher ranges of permeability and lower pressures. On the western outskirts of the basin, there is a transition zone characterized with lower ranges of permeability and higher pressures. Since the permeability is lower in the transition zone, it is uncertain whether this area is suitable for CO2 sequestration and if it can deliver enhanced coal bed methane recovery. The purpose of this research is to determine the economic feasibility of sequestering CO2 to enhance coal bed methane production in the transition zone of the San Juan Basin Fruitland coal seams. The goal of this research is two- fold. First, to determine whether there is a potential to enhance coal bed methane recovery by using CO2 injection in the transition zone of the San Juan Basin. The second goal is to identify the optimal design strategy and utilize a sensitivity analysis to determine whether CO2 sequestration/ECBM is economically feasible. Based on the results of my research, I found an optimal design strategy for four 160-acre spacing wells. With a high rate injection of CO2 for 10 years, the percentage of recovery can increase by 30% for methane production and it stores 10.5 BCF of CO2. The economic value of this project is $17.56 M and $19.07 M if carbon credits were granted at a price of $5.00/ton. If CO2 was not injected, the project would only give $15.55 M.
