Amongst others this policy aims to reduce greenhouse gas emissions by at least 20% compared to 1990 and to ensure that 20% of total energy use comes from renewable sources, partly by increasing the share of biofuels up to at least 10% of total fuel use in transportation. In meeting the 20% reduction ceiling for greenhouse gas emissions the EU Emissions Trading Scheme (EU-ETS) will play a central role as the ‘pricing engine’ for CO 2-emissions. The higher the emissions price will be, the sooner technological emission reduction options will tend to be commercially adopted.

  • The Sustainability of Cellulosic Biofuels
    The Sustainability of Cellulosic Biofuels All biofuels, by definition, are made from plant material. The main biofuel on the U.S. market is corn ethanol, a type of biofuel made using the starch in corn grain. But only using grain to produce biofuels can lead to a tug of war between food and fuel sources, as well as other environmental and economic challenges. Biofuels made from cellulosic sources – the leaves, stems, and other fibrous parts of a plant – have been touted as a promising renewable energy source. Not only is cellulose the most abundant biological material on Earth, but using cellulose to produce biofuels instead of grain can have environmental benefits. Cellulosic biofuel sources offer a substantially greater energy return on investment compared to grain-based sources. However, environmental benefits are not guaranteed. The environmental success of cellulosic biofuels will depend on 1) which cellulosic crops are grown, 2) the practices used to manage them, and 3) the geographic location of crops. Both grain-based and cellulosic biofuels can help lessen our use of fossil fuels and can help offset carbon dioxide emissions. But cellulosic biofuels are able to offset more gasoline than can grain-based biofuels – and they do so with environmental co-benefits. Cellulosic Biofuels Help Reduce Competition for Land Cellulosic fuel crops can grow on lands that are not necessarily suitable for food crops and thereby reduce or avoid food vs. fuel competition. If grown on land that has already been cleared, cellulosic crops do not further contribute to the release of carbon to the atmosphere. Because many cellulosic crops are perennial and roots are always present, they guard against soil erosion and better retain nitrogen fertilizer.

Foreword The global energy supply system is currently in transition from one that relies on polluting and depleting inputs to a system that relies on non-polluting and non-depleting inputs that are dominantly abundant and intermittent. Optimising the stability and cost-effectiveness of such a future system requires seamless integration and control of various energy inputs. The role of energy supply management is therefore expected to increase in the future to ensure that customers will continue to receive the desired quality of energy at the required time. The COP21 Paris Agreement gives momentum to renewables. The IPCC has reported that with current GHG emissions it will take 5 years before the carbon budget is used for +1,5C and 20 years for +2C.

  • Biofuels in a Changing World
    Biofuels in a Changing World Carol Werner, Executive Director Environmental and Energy Study Institute Presentation for Biofuels and the Promise for Sustainable Energy Conference in Rio de Janeiro, Brazil August 2007 Abstract : The twin drivers of oil security and climate change have pushed biofuels into the forefront of US national energy policy. The industry has grown rapidly, and at this point is based upon corn ethanol and soy biodiesel. A variety of policy proposals are before the US Congress in terms of major pending energy and agriculture legislation which would greatly advance the role of biofuels. At the same time concerns have been raised about the cost of such proposals, the sustainability of biofuel production, potential competition with food, animal feed and other crops as well as land use issues. Biofuels represent an important piece of the solution to the challenges of a world facing climate change and oil security concerns – but are not a silver bullet. Instead, they must be part of a ‘sustainable’ strategy that works in tandem with other policies that will allow us to address multiple issues to achieve multiple benefits at the same time. Key elements that must be addressed include diversification of feedstocks that are appropriate to given regions based upon local soil, precipitation, low inputs and climate conditions; encouragement of local ownership so that local economic activity is enhanced; and development of new technologies and biorefineries that will promote high efficiency and a low/no net carbon emission life cycle. Without addressing these issues carefully and thoughtfully – whether in the United States, Brazil or other countries moving forward on biofuels – we run the risk of jeopardizing public consensus for long-term support of biofuels as well as jeopardizing the long term environmentally sustainable economic development that is critical to the well-being of our societies and our planet.

  • Modelling of Emissions and Energy Use from Biofuel Fuelled Vehicles at Urban Scale
    sustainability Article Modelling of Emissions and Energy Use from Biofuel Fuelled Vehicles at Urban Scale Daniela Dias, António Pais Antunes and Oxana Tchepel * CITTA, Department of Civil Engineering, University of Coimbra, Polo II, 3030-788 Coimbra, Portugal; [email protected] (D.D.); [email protected] (A.P.A.) * Correspondence: [email protected] Received: 29 March 2019; Accepted: 13 May 2019; Published: 22 May 2019 Abstract: Biofuels have been considered to be sustainable energy source and one of the major alternatives to petroleum-based road transport fuels due to a reduction of greenhouse gases emissions. However, their effects on urban air pollution are not straightforward. The main objective of this work is to estimate the emissions and energy use from bio-fuelled vehicles by using an integrated and flexible modelling approach at the urban scale in order to contribute to the understanding of introducing biofuels as an alternative transport fuel. For this purpose, the new Traffic Emission and Energy Consumption Model (QTraffic) was applied for complex urban road network when considering two biofuels demand scenarios with different blends of bioethanol and biodiesel in comparison to the reference situation over the city of Coimbra (Portugal). The results of this study indicate that the increase of biofuels blends would have a beneficial effect on particulate matter (PM ) emissions reduction for the entire road network ( 3.1% [ 3.8% to 2.1%] by kg). In contrast, 2.5 − − − an overall negative effect on nitrogen oxides (NOx) emissions at urban scale is expected, mainly due to the increase in bioethanol uptake. Moreover, the results indicate that, while there is no noticeable variation observed in energy use, fuel consumption is increased by over 2.4% due to the introduction of the selected biofuels blends.

This study aims to evaluate and compare the influence of waste cooking oil synthetic diesel (WCOSD) with that of commercial diesel (CD) fuel on an engine’s operating characteristics. The second goal of this study is to compare the engine performance and temperature characteristics of cooling water and lubricant oil under various engine operating conditions of a test engine fueled by waste cooking oil and CD. The results indicated that the engine torque of the engine running with WCOSD dropped from 1.9 Nm to 5.4 Nm at all speeds, and its brake specific fuel consumption (BSFC) dropped at almost every speed. Thus, the thermal brake efficiency (BTE) of the engine fueled by WCOSD was higher at all engine speeds. Also, the engine torque of the WCOSD-fueled engine was lower than the engine torque of the CD-fueled engine at all engine speeds.

  • Is Biopower Carbon Neutral?
    Is Biopower Carbon Neutral? Kelsi Bracmort Specialist in Agricultural Conservation and Natural Resources Policy February 4, 2016 Congressional Research Service 7-5700 www.crs.gov R41603 Is Biopower Carbon Neutral? Summary To promote energy diversity and improve energy security, Congress has expressed interest in biopower—electricity generated from biomass. Biopower, a baseload power source, can be produced from a large range of biomass feedstocks nationwide (e.g., urban, agricultural, and forestry wastes and residues). The two most common biopower processes are combustion (e.g., direct-fired or co-fired) and gasification, with the former being the most widely used. Proponents have stated that biopower has the potential to strengthen rural economies, enhance energy security, and minimize the environmental impacts of energy production. Challenges to biopower production include the need for a sufficient feedstock supply, concerns about potential health impacts to nearby communities from the combustion of biomass, and its higher generation costs relative to fossil fuel-based electricity. At present, biopower generally requires tax incentives to be competitive with conventional fossil fuel-fired electric generation. An energy production activity typically is classified as carbon neutral if it produces no net increase in greenhouse gas (GHG) emissions on a life-cycle basis. The legislative record shows minimal debate about the carbon status of biopower. The argument that biopower is carbon neutral has come under scrutiny in debate on its potential to help meet U.S. energy demands and reduce U.S. GHG emissions. Whether biopower is considered carbon neutral depends on many factors, including the definition of carbon neutrality, feedstock type, technology used, and time frame examined.

  • Ethanol and the Environment: Delivering on the Promise of a Sustainable Biofuel by Nathanael Greene*
    Ethanol and the Environment: Delivering on the Promise of a Sustainable Biofuel By Nathanael Greene* Introduction The United States has just 3 percent of the world’s oil reserves, and domestic production has been declining since 1970. Demand is soaring–driven largely by the transportation sector, which is 97 per- cent reliant on oil. As a result, we are forced to import 60 percent of our oil, and by 2025, we will import nearly 70 percent. Our depen- dence funnels billions of dollars to shaky and hostile regions, and defense and foreign policy experts increasingly point to our oil addiction as a national security emergency. In addition America’s cars, trucks, and buses account for 27 per- cent of U.S. global warming pollution, as well as soot and smog that damage human lungs, and oil price spikes have preceded each of the major recessions over the last 30 years. Oil is the Achilles’ heel of America’s security and economy and threatens the environment we want to leave to our children. Biofuels, especially ethanol derived from the cellulosic part of plants rather than just the starch, are the most promising alternative fuels for the transportation sector. Replacing oil with biofuels would allow us to reinvest billions of dollars in our factories and farms. If we start now on an aggressive plan to develop and deploy advanced biofuels by 2050: * Nathanael Greene is Senior Policy Analyst at the Natural Resources Defense Council. 43 A HIGH GROWTH STRATEGY FOR ETHANOL • Cellulosic biofuels can displace nearly 8 million barrels of oil per day—nearly equal to all of the oil used by light-duty vehicles today; • Biofuels can be second only to vehicle fuel economy improve- ments in the amount of oil they save; • Biofuels, vehicle efficiency, and smart growth could eliminate virtually all our demand for gasoline; and • Biofuels could reduce global warming pollution by 1.7 billion tons per year—22 percent of total U.S.
