Book Description
Biomass conversion into forms of energy is receiving current attention because of environmental, energy and agricultural concerns. The purpose of this thesis is to analyze the environmental, energy, economic, and technological aspects of using a form of biomass, switchgrass (panicum virgatum), as a partial or complete replacement for coal in power generation and cogeneration systems. To examine the effects of such a substitution, an environmental biocomplexity approach is used, wherein the agricultural, technological, economic, and environmental factors are addressed. In particular, lifecycle analysis (LCA) and a three-dimensional integrated economic, energy and environmental analysis is employed. The effectiveness of alternate technologies for switchgrass preparation, harvest and use in terms of greenhouse gas impact, cost and environmental implications is examined. Also, different scenarios of cofiring and biomass preparation pathways are investigated. Optimization of the total biomass power generation cost with minimum greenhouse gas effect is undertaken using mathematical programming for various alternate competitive biomass processing pathways. As a byproduct of this work a generic tool to optimize the cost and greenhouse gas emissions for allocation of fuel sources to the power generating sinks is developed. Further, this work discusses the sensitivity of the findings to varied cofiring ratios, coal prices, hauling distances, per acre yields, etc. Besides electricity generation in power plants, another viable alternative for reducing greenhouse gases (GHGs) is the utilization of biomass in conjunction with combined heat and power (CHP) in the process industries. This work addresses the utilization of biowaste or biomass source in a processing facility for CHP. A systematic algebraic procedure for targeting cogeneration potential ahead of detailed power generation network design is presented. The approach presented here effectively utilizes the biomass and biowaste sources as external fuel, and matches it with the use and dispatch of fuel sources within the process, heating and non-heating steam demands, and power generation. The concept of extractable energy coupled with flow balance via cascade diagram has been used as a basis to construct this approach. The work also discusses important economic factors and environmental policies required for the cost-effective utilization of biomass for electricity generation and CHP.

Book Description
Developing the Global Bioeconomy: Technical, Market, and Environmental Lessons from Bioenergy brings together expertise from three IEA-Bioenergy subtasks on pyrolysis, international trade, and biorefineries to review the bioenergy sector and draw useful lessons for the full deployment of the bioeconomy. Despite the vast amount of politically driven strategies, there is little understanding on how current markets will transition towards a global bioeconomy. The question is not only how the bioeconomy can be developed, but also how it can be developed sustainably in terms of economic and environmental concerns. To answer this question, this book’s expert chapter authors seek to identify the types of biorefineries that are expected to be implemented and the types of feedstock that may be used. They also provide historical analysis of the developments of biopower and biofuel markets, integration opportunities into existing supply chains, and the conditions that would need to be created and enhanced to achieve a global biomass trade system that could support a global bioeconomy. As expectations that a future bioeconomy will rely on a series of tradable commodities, this book provides a central accounting of the state of the discussion in a multidisciplinary approach that is ideal for research and academic experts, and analysts in all areas of the bioenergy, biofuels, and bioeconomy sectors, as well as those interested in energy policy and economics. Examines the lessons learned by the bioenergy industry and how they can be applied to the full development of the bioeconomy Explores different transition strategies and how the current fossil based and future bio-based economy are intertwined Reviews the status of current biomass conversion pathways Presents an historical analysis of the developments of biopower and biofuel markets, integration opportunities into existing supply chains, and the conditions that would need to be created and enhanced to achieve a global biomass trade system

Book Description
This Handbook is the first volume to comprehensively analyse and problem-solve how to manage the decline of fossil fuels as the world tackles climate change and shifts towards a low-carbon energy transition. The overall findings are straight-forward and unsurprising: although fossil fuels have powered the industrialisation of many nations and improved the lives of hundreds of millions of people, another century dominated by fossil fuels would be disastrous. Fossil fuels and associated greenhouse gas emissions must be reduced to a level that avoids rising temperatures and rising risks in support of a just and sustainable energy transition. Divided into four sections and 25 contributions from global leading experts, the chapters span a wide range of energy technologies and sources including fossil fuels, carbon mitigation options, renewables, low carbon energy, energy storage, electric vehicles and energy sectors (electricity, heat and transport). They cover varied legal jurisdictions and multiple governance approaches encompassing multi- and inter-disciplinary technological, environmental, social, economic, political, legal and policy perspectives with timely case studies from Africa, Asia, Australia, Europe, North America, South America and the Pacific. Providing an insightful contribution to the literature and a much-needed synthesis of the field as a whole, this book will have great appeal to decision makers, practitioners, students and scholars in the field of energy transition studies seeking a comprehensive understanding of the opportunities and challenges in managing the decline of fossil fuels.

Book Description
This book combines three different energy-economy-emissions modeling methodologies into one Integrated Modeling Framework (IMF) in an attempt to fill gaps in current modeling research as it applies to developing countries. Through the analysis of existing mathematical models, including large macro-economic models and technology-explicit energy models, the work proposes planning methodologies for developing countries that face challenges on their economy and infrastructure due to climate change. The three modeling methodologies discussed in the chapters are a decomposition analysis of trends in emissions intensity of GDP, linear programming techniques to determine optimum energy supply pathways given various resource and emissions constraints, and an input-output analysis to evaluate the impact of energy policies on income and equity. After a brief introduction to the history of the development of energy studies and the linkages between energy, economic, and environmental systems, the book delves into the component methodologies of the IMF and their intended outcomes. The decomposition analysis is intended to gauge the energy intensity of GDP and the structural composition of the economy to provide a basis on which scenarios are constructed in the following two methodologies. The linear programs are meant to develop a methodology to determine energy options under a variety of scenarios that capture the technical and economic characteristics of the power sector of developing countries. Lastly, the input-output analysis aims to build a methodology through which energy policy decisions can be understood and quantified to ensure the best possible impacts on developing economies and societies. Those who will be interested in this book include policy makers, academics, and students and professionals working on energy studies and energy-economy modeling.

Book Description
Being depletable, scarce, hostile to the environment and non-renewable in nature, petroleum-based fossil fuels are diminishing much faster than a decade ago. These scarcity concerns, negative environmental consequences and the gradual depletion of petroleum fuels have led to explore alternate, inexhaustible and renewable energy resources. One promising energy resource is biofuel, which is produced from renewable biomass feedstock. The reasons for sustainability and viability of biofuels are that they are economically feasible to produce and have positive environmental impacts. Since biofuels research is quite diversified, the sustainability and viability of biofuels face many challenges. This thesis investigates existing and future technological and knowledge challenges and proposes new methods to improve bio-energy sustainability both economically and environmentally. The economic viability of biofuels is associated with biofuel cost estimation, the revenue earned, and the profit gained. This research evaluates the cost risk escalation and identifies the key cost factors associated with the economic viability of biofuels. To achieve this objective, this research presents an innovative methodology to perform probabilistic economic risk analysis of biofuel, and particularly biodiesel. Being stochastic in nature, the proposed methodology addresses the shortcomings of traditional biodiesel process economics and provides flexibility to deal with uncertainty in biodiesel process economics. The environmental aspects covered in this research are environmental impacts caused by all inputs to the biodiesel production process, including biomass feedstock, fresh or recycled materials and energy streams and outputs such as biodiesel, by-products and waste materials discharged into the soil and air. To address the influences of potential risks on biodiesel production and its environmental impacts, this thesis presents a new approach to perform probabilistic economic modelling, qualitative and quantitative risk assessment of biodiesel key performance indicators (KPIs) and life cycle assessment (LCA) of biodiesel fuel. Interpretive structural modelling (ISM) is used to model causation behaviour of the biodiesel process, operations and design risk factors. The basic premise of ISM is that qualitative interdependent relationships among various risk factors are achieved through experts' opinions and a scientific approach. This thesis develops an objective risk analysis approach to integrate ISM and uses a Bayesian network (BN) to define the relationship and the strength of relationship among various cost related risk factors and studies their impact on biodiesel process economics. Addressing global environmental issues and considering the vital need of edible oil for food, this thesis also presents the LCA of biodiesel being produced from inedible oils and waste cooking oil (WCO) and performs the investigation using a systematic approach of life cycle thinking. The negative environmental consequences of biodiesel fuels on climate change (global warming), ecosystem quality and human health are explored in detail. The study also identifies the total environmental impacts of using these biomass feedstocks. A comparative LCA study of technological processes identifies which biodiesel production process has the most and the fewest ecological impacts and energy requirements. Finally, this research develops advanced methods for biodiesel process economics such as process value at risk (VaR), to be used in assessing the performance of biodiesel systems. The stochastic modelling process and interdependence of a BN format help to investigate the most significant risk factors in the biodiesel process and operations. The results facilitate the decision-making process for new product development (NPD) and process development, especially at a large industrial scale. Applications of the proposed economic risk assessment framework along with an LCA study help to develop effective biodiesel policy-making by describing scientific uncertainties related to process economics and the environmental impact of biodiesel production technologies. In another arena of application, this thesis helps to develop a strategic decision-making process for supply chain management of biomass feedstock as well as biodiesel. It also enhances the biodiesel process-based risk informed decision-making process by incorporating techno-economic and life cycle accounting decisions.
