Emission balances of first -and second- generation biofuels by Dorian Frieden,Naomi Pena,David Neil Bird,Hannes Schwaiger,Lorenza Canella Pdf

This report examines and compares the greenhouse gas emissions of alternative first-generation and second-generation biofuel production pathways. The emissions balance analysed include greenhouse gas emissions from cultivation, land use change, processing and transport of biofuels. The biofuel production pathways reviewed are: -Biodiesel from palm oil in Indonesia, -Biodiesel from jatropha in South Africa and Mexico, -Bioethanol from sugar cane in South Africa, Mexico and Indonesia, -Bioethanol from wood in South Africa and Mexico, -Fischer-Tropsch diesel from wood in South Africa and Mexico Most calculations are undertaken using a tool developed by the BioGrace project funded by the European Union. For land use change emissions, three default values based on results from the partial equilibrium Global Biomass Optimisation Model (GLOBIOM) are used. An allocation of greenhouse gas emissions to the biofuel and its co-products is done by using the energy allocation method. The results show that wherever a land use change default value for non-wood feedstocks is used, this value dominates by far all other emission sources. Default land use change emissions for pathways using wood as feedstock are minor (short rotation coppice) or negative (wood from existing forests). However, woody feedstocks require second-generation conversion technologies. The least emission intensive first-generation pathways are bioethanol from sugar cane in Mexico and Indonesia due to the high productivity of sugar cane and the simple conversion process. Due to the limited country-specific database, a differentiation between countries or regions could not clearly be made. Differentiation can rather be done for the importance of particular factors such as feedstock productivity in conjunction with fertiliser use, allocation of co-products or the energy demand of specific conversion technologies.

Are biofuels sustainable? by Great Britain: Parliament: House of Commons: Environmental Audit Committee Pdf

Biofuels can reduce greenhouse gas emissions from road transport-but most first generation biofuels have a detrimental impact on the environment overall. In addition, most biofuels are often not an effective use of bioenergy resources, in terms either of cutting greenhouse gas emissions or value-for-money. The Government must ensure that its biofuels policy balances greenhouse gas emission cuts with wider environmental impacts, so that biofuels are only used where they contribute to sustainable emissions reductions. The Government and EU's neglect of biomass and other more effective policies to reduce emissions in favour of biofuels is misguided. The current policy and support framework must be changed to ensure that sustainable bioenergy resources maximise their potential to generate energy for the lowest possible greenhouse gas emissions. In general biofuels produced from conventional crops should no longer receive support from the Government. Instead the Government should concentrate on the development of more efficient biofuel technologies that might have a sustainable role in the future. The Government should seek to ensure that EU policy changes to reflect the concerns raised in this report. This means implementing a moratorium on current targets until technology improves, robust mechanisms to prevent damaging land use change are developed, and international sustainability standards are agreed. Only then might biofuels have a role to play. In the meantime, other more effective ways of cutting emissions from road transport should be pursued. It will take considerable courage for the Government and EU to admit that the current policy arrangements for biofuels are inappropriate. The policy realignments that are required will be a test of the Government's commitment to moving the UK towards a sustainable low carbon economy.

Handbook of Bioenergy Economics and Policy: Volume II by Madhu Khanna,David Zilberman Pdf

In its second volume, this book aims to link the academic research with development in the real world and provide a historical and institutional background that can enrich more formal research. The first section will include an assessment of the evolution and the state of the nascent second-generation biofuel as well as a perspective on the evolution of corn ethanol and sugarcane ethanol in Brazil. 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.

Biofuels and Sustainability by Kazuhiko Takeuchi,Hideaki Shiroyama,Osamu Saito,Masahiro Matsuura Pdf

This open access book presents a comprehensive analysis of biofuel use strategies from an interdisciplinary perspective using sustainability science. This interdisciplinary perspective (social science-natural science) means that the strategies and policy options proposed will have significant impacts on the economy and society alike. Biofuels are expected to contribute to reducing greenhouse gas emissions, revitalizing economies in agricultural communities and alleviating poverty. However, despite these anticipated benefits, international organizations such as the FAO, OECD and UN have published reports expressing concerns that biofuel promotion may lead to deforestation, water pollution and water shortages. The impacts of biofuel use are extensive, cross-sectoral and complex, and as such, comprehensive analyses are required in order to assess the extent to which biofuels can contribute to sustainable societies. Applying interdisciplinary sustainability science concepts and methodologies, the book helps to enhance the establishment of a sustainable society as well as the development of appropriate responses to a global need for urgent action on current issues related to biofuels.

Third Generation Biofuels by Pratima Bajpai Pdf

Growing concerns about the rapid depletion of fossil fuel reserves, rising crude oil prices, energy security and global climate change have led to increased worldwide interest in renewable energy sources such as biofuels. In this context, biofuel production from renewable sources is considered to be one of the most sustainable alternatives to fossil fuels and a viable means of achieving environmental and economic sustainability. Although biofuel processes hold great potential to provide a carbon-neutral route to fuel production, first-generation production systems are characterized by considerable economic and environmental limitations. The advent of second-generation biofuels is intended to produce fuels from lignocellulosic biomass, the woody part of plants that does not compete with food production. However, converting woody biomass into fermentable sugars requires costly technologies. Therefore, third-generation biofuels from microalgae are considered to be a viable alternative energy resource, free from the major drawbacks associated with first and second-generation biofuels. This book examines the background of third-generation biofuel production; the advantages of algae over traditional biofuel crops; algal biomass production; algae harvesting and drying methods; production of biofuel from microalgae; and future prospects. .

Microbiology of Green Fuels by Abu Yousuf,Elia Tomás-Pejó Pdf

The replacement of fossil-derived compounds by bio-based fuels and chemicals is crucial for the implementation of a sustainable bioeconomy. In this context, microorganisms are key players for biofuels’ production from renewable sources. Biotechnological biofuel production processes require conversion microorganisms capable of both efficiently assimilating renewable low-cost carbon sources and diverting their metabolisms towards the specific biofuel. Exploring the wide diversity of microorganisms available on Earth will surely aid to make the production of green fuels a reality. This book gives a wide overview of different microbial-based processes for green fuels production. The book also includes techno-economic analysis and highlights strategic, commercial and environmental interests in promoting green fuels. All these facts make this book very valuable not only for the scientific community but also for biofuel companies and policy makers.
