Central Steam Plant Biomass Solution. ORNL is working to convert the laboratory's steam plant operations to a biomassfueled boiler system. Biomass (i.e, renewable wood and wood products) will replace most of the natural gas and fuel oil currently used to provide steam to ORNLBiomass for electricity and heating Opportunities and challenges SUMMARY Biomass is a renewable energy source which can be used to produce electricity, heat and transport fuels. It accounts for roughly two thirds of renewable energy in the European Union (EU). Although biomass can come from many different sources, wood
Oak Ridge National Laboratory (ORNL) will be saving nearly $4 million a year by switching a portion of their current natural gasfueled steam plant for one powered by biofuel.The move is part of an Energy Savings Performance Contract that will ultimately cut the Lab's fossil fuel consumption by 70 percent per year saving 120,000 barrels of oil, the same amount used to power 4,500 homes inEconomic Modeling of Forest Biomass Supply for Bioenergy Production in Southern United States. as bio products such as highly compact wood pellets used for heating purposes. The total wood demand for energy has been estimated in terms of these three types of energies. conversion factor (3,412 BTU per KWH) at a 25 percent level of
ORNL Biomass Wood Fuelled Heating,Dibenzo(a,e)pyrene occurs ubiquitously in products of incomplete combustion. It is present as a component of the total content of PAHs in the environment. Dibenzo(a,e)pyrene occurs in tobacco smoke, gasoline and diesel engine exhaust, stack emissions of waste incinerators, in coal combustion stack emissions, and in curing smoke.The need for a rapid reduction in greenhouse gases is well known, and bioenergy is one of the possible solutions. The new perennial grass crop Miscanthus is particularly promising for bioenergy, as it is hardy, fast growing and efficient in its use of water. Jonathan Harvey reviews the technical and commercial progress, and future prospects, for the crop.
Forest Heat Energy were approached to design a biomass solution to replace the school's reliance on kerosene heating oilfired boilers, benefit from lower cost wood fuel, and the Government Renewable Heat Incentive Scheme, whilst also reducing their carbon footprint.Status: Resolved
Abstract. Bioenergy is derived from various biological sources, called biomass, and is considered a renewable energy source, since biomass can be replenished on a regular basis.Biomass offers opportunity in every part of the world to develop sustainable resourcesStudies of forest biomass based energy production raise concerns regarding soil compaction and rutting (Reijnders 2006), decreased amounts of decaying wood on forested landscapes, changes in the chemical and physical environment of soils (Astrom and others 2005), increased use of agrochemicals (Fritsche and others 2006), increased soil erosion
Since the United States began a programme to develop ethanol as a transportation fuel, its use has increased from 175 million gallons in 1980 to 4.9 billion gallons in 2006. Virtually all of the ethanol used for transportation has been produced from corn. During the period of fuel ethanol growth, corn farming productivity has increased dramatically, and energy use in ethanol plants has beenResults. Ethanol production costs for current technologies decrease significantly from $0.71 to $0.58 per litre with increasing economies of scale, up to a maximum singleplant capacity of 550 × 10 6 l year1.The development of highyielding energy crops and consolidated bioprocessing realises significant cost reductions, with production costs ranging from $0.33 to $0.36 per litre.
Biodiesels (fatty acid methyl esters) derived from oleaginous microbes (microalgae, yeast, and bacteria) are being actively pursued as potential renewable substitutes for petroleuA guide to smallscale wood fuel (biomass) heating systems This guide has been written by the Wood Fuel South West Advice Service a project funded by Woodland Renaissance, Areas of Outstanding Natural Beauty in the South West (AONBs) and the Forestry Commission. It is for people interested in finding out more about biomass boiler systems.

[editor's note, by Prof. Goose] Forget not the reddit and digg buttons! The time has come to put the ongoing biomass debate in a larger context. My thanks to many TOD participants for their informative comments. I usually work the "problem" side ofBiomass Boilers. Woodfuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room – and may be fitted with a back boiler to provide water heating

Adding to demand is the even fastergrowing market for heating and hotwater systems fuelled by wood chips and pellets – which is heavily subsidised by taxpayers. The Forestry Commission and the biomass industry's lobby group, the Woodland Heat Association, insist this» Biomass feedstocks: These come in a variety of forms and have different properties that impact their use for power generation. » Biomass conversion: This is the process by which biomass feedstocks are transformed into the energy form that will be used to generate heat and/or electricity.
