  1. An Energy Scenariofor the UKBiomass and Biofuels

  2. An Energy Scenario for the UKBiomass and Biofuels Biomass Feedstocks • Woody Energy Crops • Virgin Wood • Grassy/Starchy Energy Crops • Agricultural Wastes • Food Residues • Industrial Residues

  3. An Energy Scenario for the UKBiomass and Biofuels UK Biofuel feedstocks - bioethanol • Agricultural Products - cereals and sugar beet UK Biofuel feedstocks – biodiesel • Rapeseed Oil • Agricultural By-products • tallow Imported feedstocks • Palm oil • C4 plants - maize and sugar cane

  4. An Energy Scenario for the UKBiomass and Biofuels From www.farmingfutures.org.uk

  5. An Energy Scenario for the UKBiomass and Biofuels Are Biomass and Biofuels genuinely renewable? Biomass is generally regarded as ‘carbon neutral’ • energy overheads affect this ‘carbon neutral’ balance • Emissions from fertilizer production and application, harvesting, drying, processing and transportation • DUKES lists SRC as having only 9.3GJ / tonne at 40% moisture content and 18.6GJ / tonne when dry • DECC {2009} report shows first 9 months of RTFO – only 19% of biofuels met environmental target where government target was 30%

  6. An Energy Scenario for the UKBiomass and Biofuels Biomass feedstocks have lower energy values and density than fossil fuels – so biomass most suited to small scale direct combustion Source DECC - Digest of United Kingdom energy statistics (DUKES) 2009 However – total electricity generation from plant Biomass in 2008 = 159 GWh = 572.4 TJ

  7. An Energy Scenario for the UKBiomass and Biofuels

  8. An Energy Scenario for the UKBiomass and Biofuels Technical Biodiesel – mixing with fossil fuel diesel – max 10% Physical Thetford Renewable Energy Plant capacity 40MW, requires c. 300,000 tonnes waste wood per year - 50 - 85 deliveries a day to run at max capacity. Regulatory constraints RTFO – Renewable Transport Fuels Obligation – introduced in April 2008 – fuel duty on Biodiesel only 20p / litre - to cease this year. RO - Renewables Obligation - to finish – 2002 – March 2011 Bio-energy Capital Grants Scheme and Energy Crops Scheme Renewable Heat Incentive – to start – March 2011

  9. Heat Generation Based on DUKES 2008 594 toe biomass and 150 GJ / ha for 20% mc air dried wood 40 PJ would put 24% of UK’s 1.1M hectares of woodland into heat generation UK Biomass for Electricity Production Based on DUKES 2008 2,768 GWh total biomass for elec. production – includes animal manure biomass, co-firing with coal and small CHP plants 20 PJ would require 130,000 ha of Miscanthus or SRC planting – 24% of area of Norfolk

  10. (UK) Biodiesel Production Based on DECC 2008 report - 886 tonnes biodiesel consumed in UK (314t domestic) 39 PJ would require about 1.2 million ha – about 27% of the UK’s area given to crops TOTAL Potential UK Biomass Production
