Waste biomass includes agricultural residues, livestock wastes, municipal wastes and industrial organic wastes. It should be utilised or otherwise, it will cause the pollution of water, soil and even the atmosphere. Gas biofuels have attracted growing attention as a renewable and clean energy carrier. Gas biofuels include biogas, biohydrogen and its mixture i.e. biohythane, which can be produced via anaerobic fermentation or other processes from waste biomass. This book focuses on the principles of gas biofuels in terms of types of biofuels, biomass species, and reactor configuration and production pathway. A number of books focus on the production of biogas or biohydrogen alone. In comparison, this book emphasizes the interactions and common knowledge of both. In addition, the potential of new technologies, such as microbial electrochemical technologies, and two-stage fermentation on gas biofuel production are highlighted and specifically discussed based on the authors' research basis. This book provides a state-of-the-art technological insight into the production of gas biofuels from waste biomass. Specifically, this book consists of three parts. In Part I, the principles for gas biofuels production from waste biomass, including biogas production (Chapter 1) and biohydrogen production (Chapter 2). Part II focuses on the technical advances on gas biofuels production. Pre-treatment of biomass was firstly introduced in Chapter 3, whereas the advances of biogas production from high-solid wastes were discussed in Chapter 4 and Chapter 5. In comparison, biohydrogen production is reviewed not only through dark fermentation (Chapter 6) but also emerging microbial electrochemical technology (Chapter 7). The co-production of biohydrogen and biomethane is reviewed in Chapter 8. In addition to the utilisation of carbon and hydrogen stored in biomass, nutrients recycling through algae technology is discussed in Chapter 9. Part III discusses the scale-up and industrialization of biofuels. An industrial case is introduced to analyse the bottlenecks and perspectives for development of gas biofuels.

The United States has seen resurgence in petroleum production, mainly driven by technology improvements -- especially hydraulic fracturing and directional drilling -- developed for natural gas production from shale formations. Application of these technologies enabled natural gas to be economically produced from shale and other unconventional formations, and contributed to the United States becoming the world's largest natural gas producer in 2009. This book focuses on the growth in U.S. oil and natural gas production driven primarily by tight oil formations and shale gas formations. It reviews selected federal environmental regulatory and research initiatives related to unconventional oil and gas extraction, including the Bureau of Land Management (BLM) proposed hydraulic fracturing rule and Environmental Protection Agency (EPA) actions. The book also provides a technological assessment of existing and emerging water procurement and management practices in shale energy producing regions of the United States.

This book addresses several aspects of the changing context of natural gas in the U.S. electric power sector. Increasingly plentiful and affordable natural gas has catalysed major changes in U.S. power generation and has helped to boost U.S. economic recovery. Increased substitution of natural gas for coal in power generation has also cut U.S. GHG emissions. However, processes to produce natural gas, shale gas in particular, have also elevated environmental and safety concerns in certain regions of the country. The rapid rise of natural gas is also beginning to drive more thought on longer-term energy policy issues such as the appropriate level of generation diversity (given the history of volatile prices for natural gas), and trajectories of natural gas use that will still allow GHG mitigation sufficient to address the climate challenge. This book is intended to help inform these energy policy and investment discussions, and outlines the current dynamics of natural gas in the power sector and the selected challenges and opportunities in the use of natural gas to generate electricity.

Nanoscale metallic and ceramic materials, also called nanomaterials, have held enormous attraction for researchers over the past few years. They demonstrate novel properties compared with conventional (microcrystalline) materials owing to their nanoscale features. Recently, mechanical alloying and powder metallurgy processes for the fabrication of metal-ceramic/alloy-ceramic nanocomposites with a unique microstructure have been developed. This book focuses on the fabrication of nanostructured hydrogen storage materials and their nanocomposites. The potential application of the research presented in the book fits well into the EU Framework Programme for Research and Innovation Horizon 2020, where one of the societal challenges is secure, clean, and efficient energy. Wherever possible, the authors have illustrated the subject by their own results. The goal of the book is to provide comprehensive knowledge about materials for energy applications to graduate students and researchers in chemistry, chemical engineering, and materials science.

Recent advances in combining two drilling techniques, hydraulic fracturing and horizontal drilling, have allowed access to large deposits of shale resources -- that is, crude oil and natural gas trapped in shale and certain other dense rock formations. As a result, the cost of that "tight oil" and "shale gas" has become competitive with the cost of oil and gas extracted from other sources. Virtually non-existent a decade ago, the development of shale resources has boomed in the United States, producing about 3.5 million barrels of tight oil per day and about 9.5 trillion cubic feet (Tcf) of shale gas per year. This book discusses the economic and budgetary effects of producing oil and natural gas from shale. It also examines the production, infrastructure, and market issues in U.S. shale gas development; and potential budgetary effects of immediately opening most federal lands to oil and gas leasing.

The recent growth in unconventional natural gas production has also produced a profusion of publications on the exploration, development, production, infrastructure, economics, uses, and environmental impacts of these resources. This book summarises the current state of published descriptions of the potential environmental impacts of unconventional natural gas upstream operations within the Lower 48 United States. It also examines the technology, impacts and regulations of hydraulic fracturing, which is a key technique that has enabled the economic production of natural gas from shale deposits, or plays.

The Environmental Protection Agency (EPA) has proposed regulations to reduce greenhouse gas (GHG) emissions from existing power plants. EPA believes that its proposed Clean Power Plan (CPP) will "protect public health, move the United States towards a cleaner environment, and fight climate change while supplying Americans with reliable and affordable power." Burning fossil fuels to produce electricity results in the release of carbon dioxide, and represents the largest source of GHG emissions in the United States. This book discusses the implications for the electric power sector. It also examines the carbon dioxide emission rate goals in EPA's proposed rule for existing power plants; and discusses the Congressional responses and options to the EPA regulation of greenhouse gases.

This book presents and discusses research in the study of natural gas systems. Topics discussed include flammability and individual risk assessment for natural gas pipelines; guidelines for developing gas fields associated with edge-water drive; fuzzy estimation and stabilisation in gas life wells based on a new stability map and human health risks assessment due to natural gas pipelines explosions.

Natural gas is considered a potential bridge fuel to a low carbon economy because it is cleaner burning than its hydrocarbon rivals coal and oil. Natural gas combustion emits about two-thirds less carbon dioxide than coal and one-quarter less than oil when consumed in a typical electric power plant. Additionally, improved methods to extract natural gas from certain shale formations has significantly increased the resource profile of the United States, which has spurred other countries to try to develop shale gas. If the United States and other countries can bring large new volumes of natural gas to market, then natural gas could play a larger role in the world's economy. This book examines key aspects of global natural gas markets, including supply and demand, as well as major U.S. developments.

This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the rate of fluid discharge, the depressurization, flashing and formation of liquid drops, the entrainment of drops into the vapor cloud, the subsequent spreading of the jet, and rate of liquid rainout to a pool on the ground. Designed in a modular fashion to permit adjustment and corrections as new data become available, its multi-layered approach contains sub-models that include the complexities of many variables, including the effect of liquid superheat, rate of bubble growth, criterion for bubble formation, and heat transfer from the liquid to the growing vapor bubble. To validate RELEASE, CCPS conducted small- and large-scale experiments using superheated water, heated liquefied chlorine, methylamine, and cyclohexane that produced valuable data in an area where data are scarce. This book gives complete access, in text and on CD-ROM, to the model and the test data, giving users an informed ability to apply the model to their own work.

This title includes a number of Open Access chapters. The number of tight oil and shale gas wells continues to rise primarily in the US, but also worldwide. The US has vast reserves of oil and natural gas, which now are commercially reachable as a result of advances in horizontal drilling and hydraulic fracturing technologies. But as hydraulic fracturing is increasingly used, concerns have been raised about potential stress on surface water and groundwater supplies from the withdrawal of water used in the process. Equally important is the growing volume of wastewater generated from hydraulically fractured oil and gas wells, requiring recycling, treatment, and disposal. Wastewater and Shale Formation Development: Risks, Mitigation, and Regulation examines four major issues, taking a scientific look from different perspectives at water use in shale gas development, potential environmental effects of wastewater from fracking, how to mitigate potential risks associated with wastewater from shale development, and regulatory approaches to the wastewater management problem With chapters from researchers in the field, this compendium volume sheds light on the important issues and challenges surrounding natural gas extraction using hydraulic fracturing and may be of interest to researchers and public policymakers alike.

Microorganisms are ubiquitously present in petroleum reservoirs and the facilities that produce them. Pipelines, vessels, and other equipment used in upstream oil and gas operations provide a vast and predominantly anoxic environment for microorganisms to thrive. The biggest technical challenge resulting from microbial activity in these engineered environments is the impact on materials integrity. Oilfield microorganisms can affect materials integrity profoundly through a multitude of elusive (bio)chemical mechanisms, collectively referred to as microbiologically influenced corrosion (MIC). MIC is estimated to account for 20 to 30% of all corrosion-related costs in the oil and gas industry. This book is intended as a comprehensive reference for integrity engineers, production chemists, oilfield microbiologists, and scientists working in the field of petroleum microbiology or corrosion. Exhaustively researched by leaders from both industry and academia, this book discusses the latest technological and scientific advances as well as relevant case studies to convey to readers an understanding of MIC and its effective management.
