  • Boosting bioenergy in Europe

    Introduction Energy in Europe is mainly produced from fossil fuels that used to be relatively cheap and convenient to transport and use. However these fuels emit pollutants and greenhouse gases into the atmosphere. Limited quantities in the world lead to unreliable supplies, causing erratic pricing in the short term and increasing the risk of socio-economic disasters in the medium term. The ...

  • Global bioenergy: problems and prospects

    This paper explores the future global potential for bioenergy. We use energy analysis, and more generally climate change effects, as our criteria for evaluation. Since widespread use of new bioenergy is probably decades away, our evaluation attempts to take into account likely future conditions. Previous research displays large variations in estimates of both energy ratio and technical potential. ...

  • A Canadian perspective on the future of biofuels and bioenergy

    Concerns about grain-based biofuels include their “impact on food prices and availability,” said David B. Layzell, and that their capacity to contribute to liquid fuels is inadequate. He said there are three main drivers for bioenergy: the rural economy, climate change, and energy security. In March 2008, the Government of Canada stated that its driver is the rural economy. “I think this is ...

  • 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 ...

  • Overview of biomass and bioenergy sources in northern B.C.

    Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes. “B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues. ...

  • 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 ...

  • Productivity and nutrient dynamics in bioenergy double-cropping systems

    Double-crop systems have the potential to generate additional feedstocks for bioenergy and livestock utilization, and also to reduce NO3–N leaching relative to sole-crop systems. Field studies were conducted near Ames, IA, during 2005–2007 to evaluate productivity and crop and soil nutrient dynamics in three prototypical bioenergy double-crop systems, and in a conventionally managed sole-crop ...

  • 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 ...

  • Biofuels and ecoagriculture: can bioenergy production enhance landscape-scale ecosystem conservation and rural livelihoods?

    Global development of the biofuel sector is proceeding rapidly, driven by national policy mandates, government subsidies, and profit opportunities for farmers, agribusiness and energy companies. To date, most investment in - and dialogue on - biofuels has focused on large-scale production of liquid transport fuels. A smaller set of efforts has explored the potential of biofuels to promote rural ...

  • Focus Bioenergy No 10 2004: Good examples for a sustainable energy system

    Over the past 25 years, bioenergy has become a large and obvious component of the Swedish energy system. There are applications of all scales, as gas or in solid or fluid forms used with modern and commercial technology. Biofuels are renewable fuels suitable to use within the energy market’s three fields – industry, residential and transport. Used with steering instruments that take the ...

  • Focus Bioenergy No 5 2004: Peat - a domestic fuel with advantages

    Total peat volume in Sweden is estimated to 100 billion m2. However, a large part of these assets are situated in wetlands that are important for biodiversity. The total climate impact of peat depends on emissions at combustion, but also on whether the extraction causes considerable natural flows of greenhouse gases from the peat land to cease. Often the total climate im-pact is well below that ...

  • Economic assessment of regional bioenergy systems in Australia: a flow analysis application

    This paper describes a modelling tool that integrates Material Flow Analysis, energy production and Greenhouse Gas (GHG) emissions accounting for biomass flows at a regional scale. This tool allows comprehensive analysis of alternative systems for management of biomass waste and bioenergy production in regional areas. Different possible options for processing a range of biomass waste streams can ...

  • 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 ...

  • Bio-char refineries: an accessible approach for the development of biomass-based industry

    Being a by-product of the well-established charcoal industry, slow pyrolysis bio-oil can be an excellent, cost-effective and renewable liquid fuel. However, even in Brazil, a country with a very clean energy profile and large-scale charcoal production, bio-oil is not properly utilised yet. A simple upgrade of traditional methods of charcoal production can significantly increase liquid fuel ...

  • 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 ...
