Robin Cotton Managing Director Head Office: Pinkworthy Barn Oakford, Tiverton, Devon, EX16 9EU Why Consider Wood Fuel? A renewable fuel and CO2 neutral Exempt from Climate Change Levy Security of supply UK will be a net importer of oil and gas in the very near future. Wood fuel will be sourced locally increasing fuel security. Price stability Wood fuel in Europe has traditionally been very price stable Potentially much lower fuel costs Added value – forestry, farming, recycling….local Automatic Wood Heating Modern high efficiency biomass boilers incorporating state of the art control technology provides equivalent or greater levels of efficiency and reliability as fossil fuel boilers Fully automatic feed Automatic ignition Capacity control Remote system control and monitoring Typical efficiency 90% + Very low ash remain – c.0.5-1.0% Context Energy White Paper [2003] set out 4 goals for energy policy To put the UK on a path to cut carbon dioxide emissions by 60% by 2050 Maintain reliability of energy supplies Promote competitive markets in the UK Ensure that every home is adequately and affordably heated Government’s Biomass Task Force Biomass task force lead by Sir Ben Gill published a report in 2005 “The potential to use biomass to reduce UK CO2 emissions is significant. But the use of biomass also contributes to other objectives notably security of energy supply and rural objectives” 1 million Hectares of land may be available for energy crops – equivalent to 8 million ODT per year 5-6 million ODT of recycled wood per year Forestry residues from existing wood land 1.5 -5 million ODT depending on markets Total of 16,000 million ODT available in medium term equivalent to about 3% of UK’s internal energy consumption or about 10% of the UK’s heating requirements.

However, the boiler system must be designed for a specific fuel quality.
