Book Synopsis Modeling Energy and Greenhouse Gas Emissions for Farm Scale Production by : Gustavo Garcia de Toledo Camargo
Download or read book Modeling Energy and Greenhouse Gas Emissions for Farm Scale Production written by Gustavo Garcia de Toledo Camargo and published by . This book was released on 2009 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for renewable sources of energy has triggered many researchers to search for new alternative fuels derived from agricultural systems. The most sustainable way to do this is to focus on strategies that maintain current food production, while producing biofuels from alternative cropping systems that maximize energy production efficiency without compromising environmental integrity. This research aimed to address the often cited challenge of sustainably supplying the biomass needed to meet the increased demand. The main purpose of this research was to use energy and greenhouse gas (GHG) analysis to explore and evaluate double cropping systems, livestock interactions, and biofuel production systems. Whole-farm computer models were used to compare these different agricultural strategies and systems. These tools simulate the whole farm systems making it possible to analyze a very large range of possibilities, and evaluate their performance under different assumptions. The Farm Energy Analysis Tool (FEAT), a static, deterministic, data-base model, was created to use a whole-farm approach to evaluate energy and GHG for different agricultural systems. This research identified cropping strategies and systems that resulted in a higher energetic efficiency and lower net GHG emission. This simple, yet effective, computer modeling approach allowed for a rapid evaluation which provided useful estimates needed for decision making and policy establishment. However, empirical evidence is needed from field experiments to validate simulation results.
Book Synopsis An Energy-limited Model of Algal Biofuel Production by :
Download or read book An Energy-limited Model of Algal Biofuel Production written by and published by . This book was released on 2013 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algal biofuels are increasingly important as a source of renewable energy. The absence of reliable thermodynamic and other property data, and the large amount of kinetic data that would normally be required have created a major barrier to simulation. Additionally, the absence of a generally accepted flowsheet for biofuel production means that detailed simulation of the wrong approach is a real possibility. This model of algal biofuel production estimates the necessary data and places it into a heuristic model using a commercial simulator that back-calculates the process structure required. Furthermore, complex kinetics can be obviated for now by putting the simulator into energy limitation and forcing it to solve for the missing design variables, such as bioreactor surface area, productivity, and oil content. The model does not attempt to prescribe a particular approach, but provides a guide towards a sound engineering approach to this challenging and important problem.
Book Synopsis Production of Biofuels and Numerical Modeling of Chemical Combustion Systems by : Miguel Torres García
Download or read book Production of Biofuels and Numerical Modeling of Chemical Combustion Systems written by Miguel Torres García and published by MDPI. This book was released on 2021-08-18 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuels have recently attracted a lot of attention, mainly as alternative fuels for applications in energy generation and transportation. The utilization of biofuels in such controlled combustion processes has the great advantage of not depleting the limited resources of fossil fuels while leading to emissions of greenhouse gases and smoke particles similar to those of fossil fuels. On the other hand, a vast amount of biofuels are subjected to combustion in small-scale processes, such as for heating and cooking in residential dwellings, as well as in agricultural operations, such as crop residue removal and land clearing. In addition, large amounts of biomass are consumed annually during forest and savanna fires in many parts of the world. These types of burning processes are typically uncontrolled and unregulated. Consequently, the emissions from these processes may be larger compared to industrial-type operations. Aside from direct effects on human health, especially due to a sizeable fraction of the smoke emissions remaining inside residential homes, the smoke particles and gases released from uncontrolled biofuel combustion impose significant effects on the regional and global climate. Estimates have shown the majority of carbonaceous airborne particulate matter to be derived from the combustion of biofuels and biomass. “Production of Biofuels and Numerical Modelling of Chemical Combustion Systems” comprehensively overviews and includes in-depth technical research papers addressing recent progress in biofuel production and combustion processes. To be specific, this book contains sixteen high-quality studies (fifteen research papers and one review paper) addressing techniques and methods for bioenergy and biofuel production as well as challenges in the broad area of process modelling and control in combustion processes.

Book Synopsis A Model for Sustainable Land Use in Biofuel Production by : Ermanno Affuso
Download or read book A Model for Sustainable Land Use in Biofuel Production written by Ermanno Affuso and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Renewable Fuel Standard aims to increase the production of biofuels to improve energy efficiency and decrease carbon dioxide emissions in the US. The effectiveness of this regulation is being debated by the scientific community regarding carbon emissions from direct and indirect land-use change. A valid alternative may be to design policies that stimulate sustainable land use in biofuel production. This article develops a model that simulates a voluntary program to increase the land use efficiency in production of biofuels. This stochastic dynamic model optimizes the sustainability of biofuels producible by including climate information and participatory decisions on land use. The model is parameterized using the Maximum Entropy econometric technique to present a simulation of the program in the State of Alabama. The results of this simulation show that participatory decisions on land-use may increase the net energy value of produced biofuel up to 215.68% and reduce the carbon emissions by 19.67% towards the state energy goals.

Book Synopsis Energy, Policy, and the Environment by : Marja Järvelä
Download or read book Energy, Policy, and the Environment written by Marja Järvelä and published by Springer Science & Business Media. This book was released on 2011-09-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sets the questions of energy and the environment in the North in the global context and further addresses historical developments, views on energy taxation and tariffs, and effects of EU energy policy. Climate change appears more frequently than ever on the top of global and national policy agendas. In the current situation traditional environmental concern and environmental policy may not suffice in the face of the global challenge as manifested by climate change and the depletion of fossil energy resources. But as new data comes to light, new energy policies and changes in economic structures are crucial for putting into action global climate policy. Crucial tasks in environmental policy are the sustainable utilisation of natural resources and the conservation of natural and human-made habitats. One of the areas of the world where this comes into play the most is in the Nordic countries. Northern societies are predominantly high tech, high consumption and high energy supply societies. And with the transition from older energy sources (wood for heating and stream water for power production) to newer ones (oil and nuclear energy) discussions on the environmental impact have led to public and corporate action. The Northern countries have been at the forefront in finding sustainable alternatives to solve conflicts arising from the rise in energy needs. However, these countries have taken different pathways with different policies in attempting to achieve this. As the needs and concerns from climate change arise, a Northern dimension, involving policies that contrast to European and global trends, emerges. Energy, Policy, and the Environment: Modeling Sustainable Development for the North explores that dimension.

It will also include a historical and institutional background on the biofuel industry in Brazil that has global lessons, and later, provide a technical overview of major analytical tools used to assess the economic, land use and greenhouse gas implications of biofuel policies at a regional and global level. Additionally, the book analyzes the various drivers for land use change both at a micro-economic level and at a macro-economic level. It presents studies that apply regional and global economic models to examine the effects of biofuel policies in the US, EU and Brazil on regional and global land use, on food and fuel prices and greenhouse gas emissions. These papers illustrate the use of partial and general equilibrium modeling approaches to simulate the effects of various biofuel policies, and includes studies showing the effects of risk aversion, time preferences and liquidity constraints on farmers decision to grow energy crops for biofuel production. By presenting the tools of lifecycle analysis for assessing the direct greenhouse gas intensity of biofuels, this handbook investigates the types of indirect or market mediated effects that can offset or strengthen these direct effects. It will include tools to assess the direct and indirect effects of biofuel production on greenhouse gas emissions in the US and Brazil, and ultimately provide a comprehensive background to understand the state of biofuel in the present and how to analyze their implication.

Book Synopsis Environmental, Economic and Policy Aspects of Biofuels by : Deepak Rajagopal
Download or read book Environmental, Economic and Policy Aspects of Biofuels written by Deepak Rajagopal and published by Now Publishers Inc. This book was released on 2008 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental, Economic and Policy Aspects of Biofuels provides a timely summary of the current issues contributing to the policy debates on this emerging and important topic. The authors make several key conclusions: - Biofuels are diverse and evolving. The next generation of biofuels has the potential to provide improved net benefits but requires significant technological breakthroughs. - Greenhouse gas (GHG) benefits vary significantly across various types of biofuels and are dependent on market conditions and policy situation. - While biofuel improves the welfare of gasoline consumers and food producers, it has a significant negative affect on food consumers, especially the poor. - A diverse set of policies, which have been introduced or proposed, impact biofuels directly including subsidies, mandates, and regulation of carbon content of fuels. However, current policies do not provide incentives that align private and social welfare. - Much of the impact assessments of biofuels thus far are ex-ante estimates based on either optimization or equilibrium models. There is a lack of ex-post econometric analysis of the marginal impact of biofuels and biofuel policies on the economy. And the structural relationships between agriculture, the energy sector, and the environment in the context of biofuels have hardly been studied. The biofuel policy debate is likely to be an ongoing one in the near future and Environmental, Economic and Policy Aspects of Biofuels should be required reading for anyone interested in understanding this diverse and growing literature.
