  • Combining strategies speeds the work of enzymes

    Enzymes could break down cell walls faster – leading to less expensive biofuels for transportation – if two enzyme systems are brought together in an industrial setting, new research by the Energy Department’s National Renewable Energy Laboratory suggests. A paper on the breakthrough, “Fungal Cellulases and Complexed Cellulosomal Enzymes Exhibit Synergistic Mechanisms in ...

  • NREL Explains the Higher Cellulolytic Activity of a Vital Microorganism

    Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) and the BioEnergy Science Center (BESC) say better understanding of a bacterium could lead to cheaper production of cellulosic ethanol and other advanced biofuels. Their discovery was made during an investigation into the performance of Clostridium thermocellum. The scientists found the microorganism utilizes the ...

  • Food or fuel? The bioenergy dilemma

    The cost of grain-based staples–such as tortillas in Mexico, beef noodles in western China, and bread in the United States– has increased around the world. There are several reasons why prices have jumped, but there’s one getting a lot of attention: the global rush for bioenergy. Crops can be used as a food or fuel; both are important ecosystem services that nature provides to people. But as ...

  • New techniques create butanol, a superior biofuel

    The fuel is butanol; it can be derived from lignocellulosic materials, which are plant biomass parts that range from woody stems and straw to agricultural residues, corn fiber and husks, all containing in large part cellulose and some lignin. Butanol is considered to be a better biofuel than ethanol because it's less corrosive and has a higher caloric value, giving it a higher energy value. Like ...

  • Bioenergy integrated in the bio-based economy crucial to meet climate targets

    The 24th European Biomass Conference and Exhibition in Amsterdam has provided a unique overview of the state of play of the sector and a much clearer view than before of the role biomass can play in achieving the transition to a low carbon economy.  After the historical Climate agreement at COP 21, international institutions and scientific organizations agree that biomass and ...

  • Maximising Africa`s bioenergy potential

    African bioenergy projects must focus on new technologies and receive stronger political support, says biofuel expert Emile van Zyl. Africa has immense potential when it comes to producing energy from biomass, particularly 'second generation' technologies that convert woody or grassy materials — including agricultural waste — into biofuels. Africa can potentially produce as much plant ...

  • Why Dedicating Land to Bioenergy Won’t Curb Climate Change

    WRI – How does bioenergy contribute to a sustainable food and climate future? A new WRI paper finds bioenergy can play a modest role using wastes and other niche fuelstocks, but recommends against dedicating land to produce ...
