This book was released on 2007-06-12 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability is a new, important discourse aimed at promoting a new strategy in the development of energy, water and environmental (EWE) systems — the key components that affect the quality of life on our planet. It is becoming increasingly clear that the quest for sustainable development requires integrating economic, social, cultural, political and ecological factors. The behavior and properties of an EWE system arise not merely from the properties of its component elements, but also to a large degree also from the nature and intensity of their dynamic interlinkages. This volume helps clarify the complexity of these problems by providing a deeper understanding of the implications of the different aspects of sustainability.This work contains a collection of selected, peer-reviewed and state-of-the-art reflecting papers that were presented at the Third Dubrovnik Conference on Sustainable Development of Energy, Water and Environment Systems that was held in June 5-10, 2005 in Dubrovnik, Croatia.

Download or read book Fundamentals of Biofuels Engineering and Technology written by Cataldo De Blasio and published by Springer. This book was released on 2019-04-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the use of biomass as an energy source and its application in energy conversion technologies. Focusing on the challenges of, and technologies related to, biomass conversion, the book is divided into three parts. The first part underlines the fundamental concepts that form the basis of biomass production, its feasibility valuation, and its potential utilization. This part does not consider only how biomass is generated, but also methods of assessment. The second part focuses on the clarification of central concepts of the biorefinery processes. After a preliminary introduction with industrial examples, common issues of biochemical reaction engineering applications are analysed in detail. The theory explained in this part demonstrates that the chemical kinetics are the core focus in modelling biological processes such as growth, decay, product formation and feedstock consumption. This part continues with the theory of biofuels production, including biogas, bioethanol, biodiesel and Fischer-Tropsch synthesis of hydrocarbons. The third part of this book gives detailed explanations of preliminary notions related to the theory of thermodynamics. This theory will assist the reader when taking into account the concepts treated in the previous two parts of the book. Several detailed derivations are given to give the reader a full understanding of the arguments at hand. This part also gives literature data on the main properties of some biomass feedstock. Fundamentals of Biofuels Engineering and Technology will be of interest not only to academics and researchers working in this field but also to graduate students and energy professionals seeking to expand their knowledge of this increasingly important area.

Download or read book Energy as a Sociotechnical Problem written by Christian Büscher and published by Routledge. This book was released on 2018-09-21 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy as a Sociotechnical Problem offers an innovative approach to equip interdisciplinary research on sociotechnical transitions with coherence and focus. The book emphasizes sociotechnical problems in three analytical dimensions: - In the control dimension, contributing authors examine how control can be maintained despite increasing complexity and uncertainty, e.g., in power grid operations or on energy markets; - In the change dimension, the authors explore if and how change is possible despite the need for stable orientation, e.g., regarding discourses, real-world labs and learning; - Finally, in the action dimension, the authors analyze how the ability to act on a permanent basis is sustained despite opaqueness and ignorance, exemplified by the work on trust, capabilities or individual motives. Drawing on contributions from engineering, economics, philosophy, political science, psychology and sociology, the book assembles a range of classic and current themes including innovation, resilience, institutional economics, design or education. Energy as a Sociotechnical Problem presents the ongoing transformation of the energy complex as a multidimensional process, in which the analytical dimensions interact with each other in shaping the energy future. As such, this book will be of great interest to students and scholars of energy transitions, energy science and environmental social science more generally, as well as to practitioners working within the field of energy policy.

This book was released on 2021-03-17 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with issues and concerns for the human environment in the developing countries incorporating natural processes and systems, pollution removal technology, energy conservation, environmental impact assessment process, economics, culture, political structure and societal equity from a management point of view. Solutions to the emerging problems of the environment need a paradigmatic shift in approach from a process based model to a socio-political-economic model. Hence environmental management should involve equality and control over use of the finite natural resources and the balance between Earth’s biocapacity and humanity’s ecological footprint. Changes such as green technologies, human population stabilization and adoption of ecologically harmonious lifestyles are absolutely essential and will require redesigning of political institutions, policies and revisiting forgotten skills of sustainable practices of environmental management. These challenges should centre on environment governance using the concepts of common property, equity and security. This book is relevant for academics, professionals, administrators and policy makers who are concerned with various aspects of environment management and governance.

Download or read book The Water Food Energy and Climate Nexus written by Felix Dodds and published by Routledge. This book was released on 2016-03-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability. It is increasingly clear that there is no place in an interlinked world for isolated solutions aimed at just one sector. In recent years the "nexus" has emerged as a powerful concept to capture these inter-linkages of resources and is now a key feature of policy-making. This book is one of the first to provide a broad overview of both the science behind the nexus and the implications for policies and sustainable development. It brings together contributions by leading intergovernmental and governmental officials, industry, scientists and other stakeholder thinkers who are working to develop the approaches to the Nexus of water-food-energy and climate. It represents a major synthesis and state-of-the-art assessment of the Nexus by major players, in light of the adoption by the United Nations of the new Sustainable Development Goals and Targets in 2015.

Download or read book Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat written by Emil Nilsson and published by Linköping University Electronic Press. This book was released on 2020-02-20 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air. Although a mismatch between heat generation and heat demand primarily being seasonal, a mismatch may also exist at times in the winter, e.g. during milder winter days or high production hours. If this excess heat instead of being sent to the outdoors was stored for later use when it is needed, purchased energy for the site could be decreased. One way to do this is by the use of a borehole thermal energy storage (BTES) system. A BTES system stores energy directly in the ground by using an array of closely drilled boreholes through which a heat carrier, often water, is circulated. So far, BTES systems used for heating purposes have mainly been used for storage of solar thermal energy. The BTES system has then been part of smaller district solar heating systems to reduce the seasonal mismatch between incoming solar radiation and heat demand, thus increasing system solar fraction. For this application of BTES systems, energy for storage can be controlled by the sizing of the solar collector area. At an industrial site, however, the energy that can be stored will be limited to the excess heat at the site, and the possible presence of several time-varying processes generating heat at different temperatures gives options as to which processes to include in the heat recovery process and how to design the BTES system. Moreover, to determine the available heat for storage at an industrial site, individual measurements of the heat streams to be included are required. Thus, this must be made more site-specific as compared to that of the traditional usage of BTES systems where solar thermal energy is stored, in which case long-time historic solar radiation data to do this is readily accessible for most locations. Furthermore, for performance predictions of industrial BTES systems to be used for both seasonal and short-term storage of energy, models that can treat the short-term effects are needed, as traditional models for predicting BTES performance do not consider this. Although large-scale BTES systems have been around since the 1970’s, little data is to be found in the literature on how design parameters such as borehole spacing and borehole depth affect storage performance, especially for industrial BTES applications. Most studies that can be found with regard to the designing of ground heat exchanger systems are for traditional ground source heat pumps, working at the natural temperature of the ground and being limited to only one or a few boreholes. In this work, the performance of the first and largest industrial BTES system in Sweden was first presented and evaluated with regard to the storage’s first seven years in operation. The BTES system, which has been used for both long- and short-term storage of energy, was then modelled in the IDA ICE 4.8 environment with the aim to model actual storage performance. Finally, the model was used to conduct a parametric study on the BTES system, where e.g. the impact on storage performance from borehole spacing and characteristics of the storage supply flow at heat injection were investigated. From the performance evaluation it could be concluded that lower than estimated quantities and/or quality of the excess heat at the site, resulting in lower storage supply flow temperatures at heat injection, has hindered the storage from reaching temperatures necessary for significant amounts of energy to be extracted. Based on the repeating annual storage behavior seen for the last years of the evaluation period, a long-term annual heat extraction and ratio of energy extracted to energy injected of approximately 400 MWh/year and 20% respectively are likely. For the comparison of predicted and measured storage performance, which considered a period of three years, predicted values for total injected and extracted energy deviated from measured values by less than 1 and 3% respectively, and predicted and measured values for injected and extracted energy followed the same pattern throughout the period. Furthermore, the mean relative difference for the storage temperatures was 4%. A time-step analysis confirmed that the intermittent heat injection and extraction, occurring at intervals down to half a day, had been captured in the three-year validation. This as predictions would become erroneous when the time step exceeded the time at which these changes in storage operation occur. Main findings from the parametric study include that 1) for investigated supply flows at heat injection, a high temperature was more important than a high flow rate in order to achieve high annual heat extractions and that 2) annual heat extraction would rapidly reduce as the borehole spacing was decreased from the one yielding the highest annual heat extraction, whereas the reduction in annual heat extraction was quite slow when the spacing was increased from this point. Another conclusion that came from the performance evaluation and the parametric study, as a consequence of the Emmaboda storage being designed as a high-temperature BTES system, intended working temperatures being 40–55 °C, was that the possibility of designing the BTES system for low working temperatures should be considered in the designing of a BTES system. Lower storage operation temperatures allow for more energy to be injected and in turn for more energy to be extracted and reduces storage heat losses to the surroundings. Ökad energieffektivisering inom industrin anses vara en nyckelkomponent för att minska koldioxidutsläpp och motarbeta klimatförändringar. För många industrier belägna i kallare klimat behövs under sommaren inte all den värme som alstras på anläggningen för att uppnå anläggningens värmebehov, och värmen avlägsnas därför till utomhusluften. Även om ett överskott av värme framförallt existerar under sommaren kan överskottsvärme även uppstå under vintern, till exempel under mildare vinterdagar eller högproduktionstimmar. Om överskottsvärmen istället för att avlägsnas till utomhusluften lagras till senare då den behövs skulle köpt energi till anläggningen kunna minskas. Ett sätt att åstadkomma detta är med hjälp av ett borrhålsvärmelager. Ett borrhålsvärmelager lagrar energi direkt i marken med hjälp av ett flertal närliggande borrhål genom vilka en värmebärare, vanligtvis vatten, cirkuleras. Hittills har borrhålsvärmelager med syfte att leverera värme framförallt använts för lagring av termisk solenergi. Borrhålsvärmelager har då ingått i solvärmesystem för uppvärmning av enstaka bostadskvarter, för att på så vis minska den säsongsbaserade missanpassningen mellan solinstrålning och värmebehov och öka värmesystemets solfraktion. För denna applikation av borrhålsvärmelager kan energimängder för lagring kontrolleras av storleken på solfångarkollektorytan. För industriella borrhålsvärmelagertillämpningar däremot, bestäms energimängder som kan lagras av den tillgängliga överskottsvärmen vid anläggningen. En industri har dessutom vanligtvis ett flertal energianvändande processer, vilka på grund av tidsvarierande drift och olika kvalitet på den alstrade värmen ger upphov till alternativ för vilka processer som bör integreras i värmeåtervinningssystemet och hur själva borrhålsvärmelagret bör utformas. För beräkning av värmemängder tillgängliga för lagring vid en industriell anläggning krävs dessutom mätdata för de individuella värmeströmmar som ska ingå i lagerprocessen, vilket betyder att detta måste genomföras mer fallspecifikt för industriella borrhålsvärmelagertillämpningar än för borrhålsvärmelager för lagring av solenergi, där historisk solinstrålningsdata för beräkning av detta är direkt tillgänglig för de flesta platser. För prediktioner av prestandan av borrhålsvärmelager användandes för både lång- och korttidslagring behövs dessutom modeller som kan hantera effekterna från korttidslagringen, vilket traditionella modeller för borrhålsvärmelagerprediktioner inte gör. Trots att storskaliga borrhålsvärmelager har byggts sedan 1970-talet finns lite data publicerat över hur olika systemparametrar så som borrhålsavstånd och borrhålsdjup påverkar lagerprestandan, särskilt med avseende på industriella borrhålsvärmelagertillämpningar. De flesta studier i litteraturen kopplat till utformning av borrhålsvärmeväxlarsystem avser traditionell bergvärme där värmepumpen arbetar mot marken vid sin naturliga temperatur och enbart ett fåtal borrhål används. I det här arbetet genomfördes först en utvärdering av det första borrhålsvärmelagret för lagring av industriell överskottsvärme i Sverige med avseende på lagrets första sju år i drift. Borrhålsvärmelagret, vilket har använts för både lång- och korttidslagring, modellerades sedan i IDA ICE 4.8 med målet att återskapa lagrets utfall. Slutligen användes den validerade borrhålsvärmelagermodellen för en parameterisering av lagret, där påverkan på inladdad och urladdad energi och borrhålsvärmelagerverkningsgrad från bland annat borrhålsavstånd och temperatur och storlek på flödet till lagret vid laddning studerades. Från uppföljningen av lagrets utfall konstaterades det att lägre än uppskattade mängder överskottsvärme och/eller kvalitet på överskottsvärmen, resulterande i lägre än uppskattade framledningstemperaturer till lagret vid laddning, har hindrat lagret från att nå temperaturer nödvändiga för att väsentliga mängder energi ska kunna hämtas upp från lagret. Baserat på det på årsbasis cykliska beteende noterat för lagret för de sista åren av utvärderingen är rimliga långsiktiga värden för urladdad energi och borrhålsvärmelagerverkningsgrad cirka 400 MWh/år respektive 20%. För jämförelsen mellan predikterad och uppmätt lagerprestanda, vilken avser en period om tre år, avvek predikterade värden för inladdad och urladdad energi från uppmätta värden med mindre än 1% respektive 3%. Värden för predikterad och uppmätt inladdad och urladdad energi följde dessutom varandra väl under de tre åren. Vidare var den genomsnittliga relativa skillnaden för lagertemperaturerna för valideringsperioden 4%. En tidsstegsanalys bekräftade att modellen hade fångat upp effekterna av den intermittenta driften av lagret, inträffande vid intervall ned till halva dygn, då prediktioner blev felaktiga när simuleringstidssteget överskred tiden för vilka ändringar mellan laddning och urladdning av lagret ägt rum. Huvudsakliga resultat från parameterstudien inkluderar att 1) för undersökta flöden till lagret vid laddning var en hög temperatur viktigare än ett stort massflöde för att uppnå en hög årlig urladdning av energi och 2) den mängd energi som på årsbasis kan hämtas upp från lagret sjönk hastigt när borrhålsavståndet minskades från det avstånd som resulterade i att mest energi kunde laddas ur, medan en långsam minskning sågs när borrhålsavståndet ökades från denna punkt. Ytterligare en slutsats kopplat till påverkan på lagerprestanda från ingående systemparametrar är att möjligheter för utformning av ett lågtemperaturlager bör beaktas vid planering av byggande av borrhålsvärmelager. Genom att reducera lagrets arbetstemperatur kan mer energi laddas in i lagret, vilket i sin tur innebär att mer energi kan laddas ur. En lägre arbetstemperatur innebär även lägre värmeförluster från lagret till dess omgivning.
