This book presents the current status of CO2 utilization from fundamental studies to industrial tests. With the development of renewable energy, carbon dioxide will become an important feedstock for the synthesis of fuels and chemicals, and CO2 utilization must be the final solution for the carbon dioxide issues. This book discusses the effective techniques for activating inert carbon dioxide and various approaches for CO2 conversion, such as homogeneous catalytic conversion, homogeneous catalytic conversion, heterogeneous catalytic conversion, photocatalytic conversion, electrocatalytic conversion, photo-thermal catalytic conversion, plasma-chemical/plasma-catalytic conversion, and bio-catalytic conversion. It also addresses the electronic and geometric structural effects of the supported catalyst on the activity and selectivity of the conversion of carbon dioxide. The significant effects from single atom catalyst to nanoparticle are also discussed, and process intensification in catalyst preparation and reaction is highlighted. Furthermore, this book contains chapters with theoretical studies, including functional theory, which has played an important role in the catalyst design, the explanation of the reaction mechanism, and in understanding the synergy of reaction and heat and mass transfer. Given its scope, this book appeals to a wider readership, especially for researchers in the field of CO2 utilization.

This book presents the catalytic conversion of carbon dioxide into various hydrocarbons and other products using photochemical, electrochemical and thermo-chemical processes. Products include formate, formic acid, alcohols, lower and higher hydrocarbons, gases such as hydrogen, carbon monoxide and syngas.

This timely book explores the lessons learned in and potentials of injecting supercritical CO2 into depleted oil and gas reservoirs, in order to maximize both hydrocarbon recovery and the storage capacities of injected CO2.The author provides a detailed discussion of key engineering parameters of simultaneous CO2 enhanced oil recovery and CO2 storage in depleted hydrocarbon reservoirs. These include candidate site selection, CO2 oil miscibility, maximizing CO2-storage capacity in enhanced oil recovery operations, well configurations, and cap and reservoir rock integrity. The book will help practicing professionals devise strategies to curb greenhouse gas emissions from the use of fossil fuels for energy production via geologic CO2 storage, while developing CO2 injection as an economically viable and environmentally sensible business model for hydrocarbon exploration and production in a low carbon economy.

Carbon capture and storage (CCS) and'negative emissions'technologies will play an essential role in mitigating the impact of global warming and meeting the temperature targets set by the IPCC and by COP21. Identifying the role and value of CCS relative to other mitigation technologies is of vital importance. This book provides a comprehensive, up-to-date overview of the major sources of carbon dioxide emission, capture and storage, as well as negative emissions technologies, and provides insight into the role and value of CCS in the industrial and power sectors. The issues associated with commercial deployment of CCS are discussed, providing potential approaches to overcome these hurdles through a combination of political, economic and R&D strategies. Carbon Capture and Storage provides the latest global perspective on the role and value of CCS in delivering temperature targets and reducing the impact of global warming. With contributions from internationally recognised leaders, this book will appeal to graduate students and researchers in academia and industry, working in chemical engineering, mechanical engineering, and energy policy.

This book provides an analysis of the reaction mechanisms relevant to a number of processes in which CO2 is converted into valuable products. Several different processes are considered that convert CO2 either in specialty chemicals or in bulk products or fuels. For each reaction, the mechanism is discussed and the assessed steps besides the dark sites of the reaction pathway are highlighted. From the insertion of CO2 into E-X bonds to the reduction of CO2 to CO or other C1 molecules or else to C2 or Cn molecules, the reactions are analysed in order to highlight the known and obscure reaction steps. Besides well known reaction mechanisms and energy profiles, several lesser known situations are discussed. Advancing knowledge of the latter would help to develop efficient routes for the conversion of CO2 into valuable products useful either in the chemical or in the energy industry. The content of this book is quite different from other books reporting the use of CO2. On account of its clear presentation, “Reaction Mechanisms in Carbon Dioxide Conversion” targets in particular researchers, teachers and PhD students.

Liberating Energy from Carbon analyzes energy options in a carbon-constrained world. Major strategies and pathways to decarbonizing the carbon-intensive economy are laid out with a special emphasis on the prospects of achieving low-risk atmospheric CO2 levels. The opportunities and challenges in developing and bringing to market novel low and zero-carbon technologies are highlighted from technical, economic and environmental viewpoints. This book takes a unique approach by treating carbon in a holistic manner—tracking its complete transformation chain from fossil fuel sources to the unique properties of the CO2 molecule, to carbon capture and storage and finally, to CO2 industrial utilization and its conversion to value-added products and fuels. This concise but comprehensive sourcebook guides readers through recent scientific and technological developments as well as commercial projects that aim for the decarbonization of the fossil fuel-based economy and CO2 utilization that will play an increasingly important role in the near- and mid-term future. This book is intended for researchers, engineers, and students working and studying in practically all areas of energy technology and alternative energy sources and fuels.

Journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for'our great green hope'—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming.Thousands of years of poor farming and ranching practices—and, especially, modern industrial agriculture—have led to the loss of up to 80 percent of carbon from the world's soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

An introduction to the global carbon cycle and the human-caused disturbances to it that are at the heart of global warming and climate change.The most colossal environmental disturbance in human history is under way. Ever-rising levels of the potent greenhouse gas carbon dioxide (CO2) are altering the cycles of matter and life and interfering with the Earth's natural cooling process. Melting Arctic ice and mountain glaciers are just the first relatively mild symptoms of what will result from this disruption of the planetary energy balance. In CO2 Rising, scientist Tyler Volk explains the process at the heart of global warming and climate change: the global carbon cycle. Vividly and concisely, Volk describes what happens when CO2 is released by the combustion of fossil fuels (coal, oil, and natural gas), letting loose carbon atoms once trapped deep underground into the interwoven web of air, water, and soil. To demonstrate how the carbon cycle works, Volk traces the paths that carbon atoms take during their global circuits. Showing us the carbon cycle from a carbon atom's viewpoint, he follows one carbon atom into a leaf of barley and then into an alcohol molecule in a glass of beer, through the human bloodstream, and then back into the air. He also compares the fluxes of carbon brought into the biosphere naturally against those created by the combustion of fossil fuels and explains why the latter are responsible for rising temperatures. Knowledge about the global carbon cycle and the huge disturbances that human activity produces in it will equip us to consider the hard questions that Volk raises in the second half of CO2 Rising: projections of future levels of CO2; which energy systems and processes (solar, wind, nuclear, carbon sequestration?) will power civilization in the future; the relationships among the wealth of nations, energy use, and CO2 emissions; and global equity in per capita emissions. Answering these questions will indeed be our greatest environmental challenge.
