Hydrothermal and Supercritical Water Processes presents an overview on the properties and applications of water at elevated temperatures and pressures. It combines fundamentals with production process aspects. Water is an extraordinary substance. At elevated temperatures (and pressures) its properties change dramatically due to the modifications of the molecular structure of bulk water that varies from a stable three-dimensional network, formed by hydrogen bonds at low and moderate temperatures, to an assembly of separated polar water molecules at high and supercritical temperatures. With varying pressure and temperature, water is turned from a solvent for ionic species to a solvent for polar and non-polar substances. This variability and an enhanced reactivity of water have led to many practical applications and to even more research activities, related to such areas as energy transfer, extraction of functional molecules, unique chemical reactions, biomass conversion and fuel materials processing, destruction of dangerous compounds and recycling of useful ones, growth of monolithic crystals, and preparation of metallic nanoparticles. This book provides an introduction into the wide range of activities that are possible in aqueous mixtures. It is organized to facilitate understanding of the main features, outlines the main applications, and gives access to further information - Summarizes fundamental properties of water for engineering applications - Compares process and reactor designs - Evaluates processes from thermodynamic, economic, and social impact viewpoints

This book is the 2nd edition of the Economics of the International Coal Trade. Coal is the single most important source of power on our planet and today accounts for 40% of electricity generation and 30% of primary energy. The world’s appetite for energy is still far from being met. Until 2050, an additional 6+ billion people will require accessto proper power. “Why Coal Continues to Power the World” introduces the reader to the global coal business; its importance; its source; its global demand, supply and trade; its use; its environmental impact; and its future. Despite recent price hikes, coal does not appear to be a popular subject today, which may explain the little attention it receives in the scientific community. Since writing the first edition during the commodity super cycle in 2006–2008, the world has changed. How has this impacted the global world of coal? This book is useful to energy economists, businessmen, politicians, university professors, high school teachers, students and anyone with an interest in how the world is powered. It is also helpful to anyone studying climate change and global warming. This new edition of the book includes previously not covered special sections on:* Coal analysis and sampling with a special section on moisture * A technical summary of all key coking coal characteristics in Appendix 2 * Coking coal, iron ore and the steel industry * Cement and petcoke markets * Global gas markets and the shale gas revolution in the US * Nuclear energy and the history of the oil market * Renewable energy and the German „Energiewende“ * Power plant technology and CO2 sequestration and processing * The role of CO2 and why man-made CO2 does not cause global warming Apart from giving an in-depth overview of the global coal business, in this book the author argues that coal is far from “dead”. Some of my key messages are contrary to popular beliefs: The importance of coal will further increase in absolute and likely even in relative terms for decades to come. Man-made CO2 has no effect on global temperatures and combustion of fossil fuels does not influence the weather. We cannot stop the advance of coal, we can only make this process as environmentally sustainable as humanly possible. Therefore, mankind needs to embrace coal as the “bridge” from the Oil Age to the Solar Age (through the “New Energy Revolution”). (4) Industrialized nations have to invest in coal and in all means to more efficiently burn coal in order to truly help the global environment and reduce global dust, SOX, and NOX emissions.

As we are moving ahead into the 21st century, our hunger for cost effective and environmentally friendly energy continues to grow. The Energy Information Administration of US has forecasted that only in the first two decades of the 21st century, our energy demand will increase by 60% compared to the levels at the end of the 20th century. Fossil fuels have been traditionally the major primary energy sources worldwide, and their role is expected to continue growing for the forecasted period, due to their inherent cost competitiveness compared to non-fossil fuel energy sources. However, the current fossil energy scenario is undergoing significant transformations, especially to accommodate increasingly stringent environmental challenges of contaminants like sulfur dioxide, nitrogen oxides or mercury, while still providing affordable energy. Furthermore, traditional fossil fuel utilization is inherently plagued with greenhouse gas emissions from combustion, especially carbon dioxide from stationary sources as well as from mobile sources. Should worldwide government policies dictate a reduction of greenhouse gas emissions, such as proposed by the Kyoto Protocol and the implementation of carbon taxes, fossil fuels would lose their significant competitive appeal in favor of nuclear energy and renewable energy sources. However, the current non-fossil fuel energy share of the worldwide energy market is merely below 15%, and therefore, it is more likely that fossil fuel energy producers would adapt to the new requirements by developing and implementing emission control technologies, and emission trades among other strategies.

This book addresses a key innovative technology for decarbonization of the energy system: hydrothermal processing. It basically consists of treating biomass and wastes in a wet form, under pressure and temperature condition. This approach is becoming more and more attractive, as new feedstock and applications are appearing on the scene of bioeconomy and bioenergy. The hydrothermal processing of various type of biomass, waste, and residues, thus, raised the interest of many researchers and companies around the world, together with downstream upgrading processes and technologies: solid products as biochar, for instance, or liquid ones as crude bioliquids, are finding new market opportunities in circular economy schemes. The Special Issue collects recent innovative research works in the field, from basic to applied research, as well as pilot industrial applications/demo. It is a valuable set of references for those investing time and effort in research in the field.

Biomass is a vital source of renewable energy, because it offers a wide range of established and potential methods for energy generation. It is also an important facet of the progression toward a sustainable energy future. The need for further development in the provision of bioenergy is underlined by challenges affecting the biomass resource base, including rising demand for biomass for food, feed, materials and fuel. This is underlined by significant concerns over factors relating to land, such as soil, nutrients and biodiversity. This book examines and analyzes Germany's decade-long initiative toward implementation of an active policy for the transition of the energy system to make greater use of renewable energy sources, which has resulted in a significant increase in the amount of biomass used for electricity, heat and transport fuel. The book begins with a review of market and resource base issues and moves on to analyze the technical options for a more integrated bioenergy use. The analysis spans the entire bioenergy provision chain including solid, liquid and gaseous biofuels. A case study offers a detailed model of the effects of smart biomass energy on the German energy system. The book closes with a view of the most promising fields and an appraisal of needed elements for a successful transition.
