  • Commericalizing cellulosic ethanol

    Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...

  • Characterization, genetic variation, and combining ability of maize traits relevant to the production of Cellulosic Ethanol

    Maize (Zea mays L.) stover has been identified as an important feedstock for the production of cellulosic ethanol. Our objectives were to measure hybrid effect and combining ability patterns of traits related to cellulosic ethanol production, determine if germplasm and mutations used for silage production would also be beneficial for feedstock production, and examine relationships between traits ...

  • EPA requests information on cellulosic biofuels and E15

    EPA is accepting public comments through May 26, 2015, on two proposed information collection requests (ICR) published in theFederal Register on Tuesday, March 24, 2015. The proposed ICRs concern projected cellulosic biofuels volumes and gasoline containing greater than 10 volume percent ethanol up to 15 volume percent ethanol (E15). Comments received will assist EPA as the agency ...

  • Current and future ethanol production technologies: costs of production and Rates of Return on invested capital

    Considering the production goals for cellulosic and advanced biofuels in the Energy Independence and Security Act of 2007 (EISA), this study compares production costs and returns on invested capital for two current and three proposed ethanol technologies. Two methods use corn grain as the feedstock, and three use cellulosic feedstocks of corn stover, switchgrass and wood chips. Baseline levels ...

  • State and federal subsidies to biofuels: magnitude and options for redirection

    Hundreds of government subsidies have fuelled the growth of ethanol and biodiesel in the USA, worth half or more their retail price. Cumulative costs under some mandate proposals exceed $1 trillion by 2030. Even using favourable assumptions, reduced greenhouse gas emissions from biofuels are far more expensive than other options: more than $100/mt CO2e even for cellulosic ethanol and nearly ...

  • Effects of biofuels vs. other new vehicle technologies on air pollution, global warming, land use and water

    The use of biofuels, particularly ethanol, has expanded in the last few years based significantly on the premise that biofuels replacing fossil fuels may reduce global warming and air pollution problems. While this claim is still being debated, the real comparison should be between biofuels and other emerging technologies. It is found here that both corn-E85 (85% ethanol/15% gasoline) and ...

  • Second Generation Biofuels Market is Expected to Reach $23.9 Billion, Global, by 2020 - Allied Market Research

    According to a new report by Allied Market Research titled, "Global Second Generation Biofuels - Size, Industry Analysis, Trends, Opportunities, Growth and Forecast, 2013 - 2020", the global second generation biofuels (Advanced Biofuels) market would reach$23.9 billion by 2020, registering a ...


  • Biofuel - Energy Supplier of the Future?

    Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...

  • EPA trims 2014 Renewable Fuel Mandate to 15.21 billion gallons, viting blend wall

    The Environmental Protection Agency proposed Nov. 15 to use its waiver authority for the first time to reduce the overall renewable fuel blending requirement for 2014. The proposed rule for the 2014 renewable fuel standard would require petroleum refiners and importers to blend 15.21 billion ...

  • Voices from India on renewable energy sources

    As we all know that all natural resources on this earth are exhaustible sooner than later.  At the current rate in growth of Energy Demand of the world, Fossil Fuels would last in the following order: Oil is expected to last only 45 years, Gas 70 years and Coal 250 years from now.  The good quality coal of low ash content, however, may last only for another 70 to 100 years. Once these ...


  • Bioenergy Outlook: Defending the renewable fuels standard

    Although major advances in climate change and renewable energy policies are unlikely this year, there is still much that can and must be done. It is true that there are major obstacles to progress in Washington DC, but further repeating the discouraging prognosis will not be helpful. Instead, Bioenergy Outlook — BioCycle’s new bioenergy column — will, in this and occasional ...

  • Oil and gas incumbents: the upside of cleantech collaboration

    The global transition to a low-carbon economy is now inevitable. Yes, there will be winners and losers. To remain dominant, energy incumbents (like Enbridge and Royal Dutch Shell) must find scalable, low-carbon energy assets to develop. Cleantech collaborations—partnerships between traditional energy companies and emerging cleantech stars—offer new ‘cleanfield’ ...

  • Falling Gasoline Use Means United States Can Just Say No to New Pipelines and Food-to-Fuel

    Freeing America from its dependence on oil from unstable parts of the world is an admirable goal, but many of the proposed solutions—including the push for more home-grown biofuels and for the construction of the new Keystone XL pipeline to transport Canadian tar sands oil to refineries on the U.S. Gulf Coast—are harmful and simply unnecessary. Gasoline use in the United States is ...
