  • Focus Bioenergy No 7 2004: Biofuels - heating for the future

    Biofuels for heating of homes and properties is rapidly making headway. Environmentally friendly, comfortable and price-worthy small-scale heating with biofuels is done using pellets or briquettes. Changing an oil burner for a pellets burner or replacing electric heating with a pellet-burning stove is often very profitable. It demands less effort than wood firing but somewhat more work than using ...

  • Bioenergy opportunities in the pulp and paper and sawmill industries

    Fernando Preto said the Canada Centre for Mineral and Energy Technology (CANMET) Energy Technology Centre in Ottawa is “not a fundamental research lab…. We help industry develop technologies.” The Biomass and Renewables Group “took a different approach, asking, ‘What’s the converted value of one dry tonne of wood?’” Preto’s team made a number of assumptions about pellet-generated heat, power, and ...

  • 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 ...

  • O3 sensitivity in a potential C4 bioenergy crop: Sugarcane in California

    The C4 perennial grasses have many potential virtues as bioenergy crops—high productivity and water use efficiency, multiyear crop cycle that minimizes replanting costs, and wide environmental adaptation. In the productive San Joaquin Valley (SJV) of California, these species also confront high levels of ozone (O3) air pollution. It is often assumed that C4 species will exhibit tolerance to O3, ...

  • Executive Order and Proposed Bill Will Boost Biobased Products and Bioenergy

    Developments in the world of biobased products and bioenergy have flourished in recent years, as reported by sources such as The Carbohydrate Economy newsletter, the USDA’s Agricultural Research Service, the New Uses Council, and In Business magazine, among others. But while each new use for crop residues or another cellulosic ethanol project brings encouragement to sustainability proponents, the ...

  • Small-scale heat and power at B.C. mills

    Fred Scott introduced the B.C. Bioenergy Network (BCBN) as an alliance between Pristine and Nexterra Energy Corp. BCBN is a network of 15–20 individuals, with 10 MW power plants located across B.C. at mill operations in forest communities. Nexterra has developed a proprietary gasification technology that “takes wood waste material and [produces] clean burning synthetic gas or syngas,” Scott said. ...

  • Small-scale electricity production from biomass

    NC Service has set up the first plant of this type in Spain Thanks to the BIOCOM Project, Nicolás Correa Service, S.A. has built the first biomass combustion plant that not only produces thermal energy, but also electricity on a small scale (130 gross kWe). The process is based on the combustion of woodchips in a furnace to produce heat that is then transferred to an ORC module, where it ...

  • Energy systems in transition: perspectives for the diffusion of small-scale wood pellet heating technology

    Promising small-scale wood pellet heating systems with sizable market potentials have started to penetrate the residential heating market in Europe and elsewhere. Despite significant technological progress, cost reduction, improved convenience and reliability, and reduced environmental impact, diffusion of such systems will nonetheless take time. Framework and market conditions, and especially ...

  • Performance, emission and combustion characteristics of DI diesel engine running on blends of calophyllum inophyllum linn oil (honne oil)/diesel fuel/kerosene

    Kerosene (K)/diesel fuel (D)/honne oil (H) blends have a potential to improve the performance and emissions and to be alternatives to neat diesel fuel (ND) and has not been reported in the literature. Experiments have been conducted on DI diesel engine when fuelled with ND, H10 (10%H + 90%D, by volume) to H30, HK10 (10%H + 45%K + 45%D), HK20 (20%H + 40%K + 40%D) and HK30 (30%H + 35%K + 35%D). The ...

  • Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review

    Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Interview with Adam Penque, Lockheed Martin Energy

    Tell us more about how and why Lockheed Martin Energy is building its position in the Waste to Energy sector. As the world population swells to more than seven billion and counting, the need for sustainable waste disposal and clean energy generation is growing with it. Lockheed Martin’s bioenergy power generation systems have the potential to solve both challenges At its ...

  • Second-generation biofuels can reduce emissions

    Second-generation biofuel crops like the perennial grasses Miscanthus and switchgrass can efficiently meet emission reduction goals without significantly displacing cropland used for food production, according to a new study. Researchers from the University of Illinois and collaborators published their findings in the inaugural edition of the journal Nature Energy. The researchers call it ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

  • Why airlines keep pushing biofuels: They have no choice

    The number of global fliers is expected to more than double in the next two decades. In order to carry all those extra passengers, airlines are turning to a technology very few can make work on a large scale: converting trash into fuel. They have no other choice. As people in countries such as China, India and Indonesia get wealthier they are increasingly turning to air travel for vacation or ...
