Book Description
In March 2013, Japanese researchers announced a breakthrough in the extraction of natural gas from methane hydrates. This marked the latest important development in the quest for energy from methane hydrate, known as the ice that burns. This book presents a comprehensive collection of up-to-date publications about this vital new resource, covering all aspects of the field, including the possible effects of hydrate gas production on climate change. Contents include: Energy Resource Potential of Methane Hydrate; Methane Hydrate Program Report to Congress - October 2012; Interagency Coordination on Methane Hydrates R&D: Demonstrating the Power of Working Together; Report of the Methane Hydrate Advisory Committee on Methane Hydrate Issues and Opportunities including Assessment of Uncertainty of the Impact of Methane Hydrate on Global Climate Change; Report to Congress - An Assessment of the Methane Hydrate Research Program and An Assessment of the 5-Year Research Plan of the Department of Energy Prepared by the Federal Methane Hydrate Advisory Committee - June 2007; An Interagency Roadmap for Methane Hydrate Research and Development; Methane Hydrates R&D Program. Methane hydrate is a cage-like lattice of ice inside of which are trapped molecules of methane, the chief constituent of natural gas. If methane hydrate is either warmed or depressurized, it will revert back to water and natural gas. When brought to the earth's surface, one cubic meter of gas hydrate releases 164 cubic meters of natural gas. Hydrate deposits may be several hundred meters thick and generally occur in two types of settings: under Arctic permafrost, and beneath the ocean floor. Methane that forms hydrate can be both biogenic, created by biological activity in sediments, and thermogenic, created by geological processes deeper within the earth. While global estimates vary considerably, the energy content of methane occurring in hydrate form is immense, possibly exceeding the combined energy content of all other known fossil fuels. The U.S. Department of Energy methane hydrate program aims to develop the tools and technologies to allow environmentally safe methane production from arctic and domestic offshore hydrates. The program includes R&D in: Production Feasibility: Methane hydrates occur in large quantities beneath the permafrost and offshore, on and below the seafloor. DOE R&D is focused on determining the potential and environmental implications of production of natural gas from hydrates. Research and Modeling: DOE is studying innovative ways to predict the location and concentration of subsurface methane hydrate before drilling. DOE is also conducting studies to understand the physical properties of gas hydrate-bearing strata and to model this understanding at reservoir scale to predict future behavior and production. Climate Change: DOE is studying the role of methane hydrate formation and dissociation in the global carbon cycle. Another aspect of this research is incorporating GH science into climate models to understand the relationship between global warming and methane hydrates.

Book Description
1. THE BEGINNINGS OF HYDRATE RESEARCH Until very recently, our understanding of hydrate in the natural environment and its impact on seafloor stability, its importance as a sequester of methane, and its potential as an important mechanism in the Earth's climate change system, was masked by our lack of appreciation of the vastness of the hydrate resource. Only a few publications on naturally occurring hydrate existed prior to 1975. The first published reference to oceanic gas hydrate (Bryan and Markl, 1966) and the first publication in the scientific literature (Stoll, et a1., 1971) show how recently it has been since the topic of naturally occurring hydrate has been raised. Recently, however, the number of hydrate publications has increased substantially, reflecting increased research into hydrate topics and the initiation of funding to support the researchers. Awareness of the existence of naturally occurring gas hydrate now has spread beyond the few scientific enthusiasts who pursued knowledge about the elusive hydrate because of simple interest and lurking suspicions that hydrate would prove to be an important topic. The first national conference on gas hydrate in the U.S. was held as recently as April, 1991 at the U.S. National Center of the U.s. Geological Survey in Reston Virginia (Max et al., 1991). The meeting was co-hosted by the U.s. Geological Survey, the Naval Research Laboratory, and the U.S.

Book Description
From a geological perspective, gas hydrates are an important feature of the shallow geosphere. If current estimates are correct, gas hydrates contain more potential fossil fuel energy than is present in conventional oil, gas and coal deposits, although it is uncertain how much of this can be exploited. They are also geological agents that affect the physical, geophysical and geochemical properties of sediments. Oceanic gas hydrates are increasingly recognized as a major potential hazard for the stability of offshore structures in various deep-water hydrocarbon provinces. The possibility also exists that a large release of methane from gas hydrates may have a significant impact on the radiative properties of the atmosphere and thus influence global climate: past, present and future. Following an introduction and overviews, this book covers analysis and modelling of hydrate formation; exploration strategy and reservoir evaluation; regional case studies; relevance to margin stability and climate change. Hydrate research informatiloln is presented from the USA, Russia, South Asia and the European Union.

Book Description
Gas hydrates represent one of the world’s largest untapped reservoirs of energy and, according to some estimates, have the potential to meet global energy needs for the next thousand years. "Methane Gas Hydrate" examines this potential by focusing on methane gas hydrate, which is increasingly considered a significant source of energy. "Methane Gas Hydrate" gives a general overview of natural gas, before delving into the subject of gas hydrates in more detail and methane gas hydrate in particular. As well as discussing methods of gas production, it also discusses the safety and environmental concerns associated with the presence of natural gas hydrates, ranging from their possible impact on the safety of conventional drilling operations to their influence on Earth’s climate. "Methane Gas Hydrate" is a useful reference on an increasingly popular energy source. It contains valuable information for chemical engineers and researchers, as well as for postgraduate students.

Book Description
Gas hydrates are ice-like crystalline substances that form a rigid cage of water molecules and entrap hydrocarbon and non-hydrocarbon gas by hydrogen bonding. Natural gas hydrate is primarily composed of water and methane. These are solid, crystalline, ice-like substances found in permafrost areas and deepwater basins around the world. They naturally occur in the pore space of marine sediments, where appropriate high pressure and low temperature conditions exist in an adequate supply of gas (mainly methane). Gas hydrates are considered as a potential non conventional energy resource. Methane hydrates are also recognized as, an influence on offshore platform stability, a major factor in climate change contributing to global warming and a significant contribution to the ocean carbon cycle. The proposed book treats various geophysical techniques in order to quantify the gas hydrate reserves and their impact on environment. The primary goal of this book is to provide the state of art for gas hydrate exploration. The target audiences for this book are non-specialist from different branches of science, graduate students and researchers.

Book Description
Over the last few decades, unprecedented global population growth has led to increased demand for food and shelter. At the same time, extraction of natural resources beyond the Earth’s resilience capacity has had a devastating effect on ecosystems and environmental health. Furthermore, climate change is having a significant impact in a number of areas, including the global hydrological cycle, ecosystem functioning, coastal vulnerability, forest ecology, food security, and agricultural sustainability. According to the Intergovernmental Panel on Climate Change (IPCC), only immediate and sustained action will prevent climate change causing irreversible and potentially catastrophic damage to our environment. This book presents various scientific views and concepts, research, reviews, and case studies on contemporary environmental issues in changing climate scenarios and highlights different adaptation measures. Increasing awareness of modern-day patterns of climate change, it addresses questions often raised by environmental scientists, researchers, policymakers and general readers.

Book Description
Tsunamis are water waves triggered by impulsive geologic events such as sea floor deformation, landslides, slumps, subsidence, volcanic eruptions and bolide impacts. Tsunamis can inflict significant damage and casualties both nearfield and after evolving over long propagation distances and impacting distant coastlines. Tsunamis can also effect geomorphologic changes along the coast. Understanding tsunami generation and evolution is of paramount importance for protecting coastal population at risk, coastal structures and the natural environment. Accurately and reliably predicting the initial waveform and the associated coastal effects of tsunamis remains one of the most vexing problems in geophysics, and -with few exceptions- has resisted routine numerical computation or data collection solutions. While ten years ago, it was believed that the generation problem was adequately understood for useful predictions, it is now clear that it is not, especially nearfield. By contrast, the runup problem earlier believed intractable is now well understood for all but the most extreme breaking wave events.

Book Description
" Although methane hydrates are not recent discoveries, it is only now that their extraction and production are becoming commercially feasible as a major new energy source. They are present offshore in almost every coastal state, and their economic potential for endowing those states with abundant natural gas – in addition to their utility as freshwater resources and as carbon sinks for captured greenhouse gases – is vast. This book presents the first treatment of the legal issues facing the future of offshore methane hydrates, taking into account both proprietary interests and environmental hazards. Starting from law and economics theory as applied to environmental accidents, the book’s analytical framework addresses how best to provide for the opportunities and challenges presented by offshore methane hydrates. Issues and topics include the following: - introduction to the science and technology of offshore methane hydrates; - methane as a green energy source; - research programmes and agendas under way in Japan, South Korea, the United States, Canada, China, and India; - carbon capture and sequestration; - risks – methane emissions, large-scale combustion events, subsea landslides, tsunamis, earthquakes, deep ocean eruptions; - strategies of risk governance – during exploration, development, production and abandonment of the extraction process; - acts that enable seeping and venting of methane; - regulatory compliance as a defense from liability; - grounds for deference to rules of civil liability; - potential impact on anthropogenic climate change; and - private regulation and market-based incentives The analysis compares and contrasts recommended legal policies with existing legal frameworks in relevant international conventions, the European Union, and the United States. Rules of civil liability are reviewed to determine when strict liability or negligence might be efficiently employed in risk governance along with the implementation of public regulations. As a road map to amending and revising existing laws and conventions, this book will be of inestimable practical value to policymakers in supporting the optimal risk governance of the development of methane hydrates. For potential entrepreneurs and operators, this book greatly reduces the legal uncertainty underlying their decision-making and investment decisions. Furthermore, this book enables a broad cross-section of legal practitioners and scholars to engage in this fascinating late arrival to the natural resources law and policy arena. "
