Renewable Heat Incentive
• Phase 1: only available for non domestic sectors:• Small = < 200kWth
– 7.6 pence per kWh up to 1,314 peak load hrs per year and 1.9 pence per kWhr after that. All metered for 20 years
• Medium = < 200 to 1,000 kWth– 4.7 pence per kWh up to 1,314 peak load hrs per year and
1.9 pence per kWhr after that. All metered for 20 years• Large = > 1,000kWth
– 2.6 pence per kWh. All metered for 20 years• Renewable Heat Premium Payments
– Details in May and launched July 2011
• Phase 2: due 2012 to include long term tariff support for domestic sector (coinciding with introduction of Green Deal)

Indicative costs of woodchip production:
The following illustrates the stages in woodchip production, the costs are indicative only:
• 1. Payment to woodland owner - £10 per wet tonne • 2. cost of felling and extraction - £20 per wet tonne• 3. cost of drying - £5 per wet tonne• 4. conversion from wet tonnes to dry (30% moisture) tonnes -
Divide by 0.7 (or multiply by 1.43) - £15 per seasoned tonne • 5. cost of chipping - £10 per seasoned tonne• 6. cost of delivery - £15 per seasoned tonne• 7. overheads 25% - £19 per seasoned tonne
TOTAL = £94 per seasoned tonne(equivalent to 3 pence per kW hr)
Note: Every woodland is different and so costs of production will vary.
The current price of woodchips of about 30mm chip size and 30% moisture content is £80 per tonne delivered. However, in the future we suspect the price will increase to around £100 per tonne (mainly due to competition for raw materials i.e. wood and the costs of harvesting from
small and sensitive sites.

BUT: not all woodfuel!

To summarise:
Woodfuel: Why?• We have quite a lot of it in SEE!• It’s carbon efficient;• It’s sustainable;• Reduces use of fossil fuels;• Helps mitigate climate change; and• It provides local jobs
Wood in construction:Why?• All of the above; plus• It’s carbon lean;• It’s thermally efficient; and• It looks good!

WoodfuelStandards

Why do we need standards?
• To encourage the best use of a sustainable resource:
– To harvest it sustainably;
– To use it most efficiently,
• in both carbon and financial terms;– To reduce negative impacts.
• To make life easier for buyers and suppliers by:
– Ensuring the fuel is suited to the boiler;
– Helping fuel buyers specify their requirements clearly;
– Helping suppliers know what is needed and how to check that their product meets the requirements;
– Helping identify problems; and
– Providing confidence in a growing market.
To strengthen trust in wood as a fuel to facilitate trade between consumers and producers

So what’s the problem?
• Perceptions:– Bureaucracy;– Complexity;– We know how to do this already!– What’s the benefit to me?
• Language:– Moisture Content – water content vs wood humidity– Weight – wet vs seasoned (30%, 20%?) vs oven dry – Volume – solid m3, stacked m3, loose m3 (logs or chips)– Calorific value – Kilowatt hours, kilojoules, BTU’s?– Carbon – or CO2
– Competition – litres, tonnes, kilowatt hours– Price - Weight, volume or kilowatt hrs?
• Cost:– Time and money
• Scale:– Industrial, local or somewhere between?

So how could we address these problems and turn
theory into reality?
12 & sponsored by:Led by the 22 March 2011
Make it simple:
• Focus on the direct benefits
• Bite size pieces
• Critical elements first
• ‘Flick and dip’
• Pictures, diagrams, examples

Main issues:
• Source: Tree, roots, waste?• Moisture content: • Particle size:• Ash• Also:
– Nitrogen– Chlorine– Energy value by weight– Energy value by loose cubic metre– Bulk Density– Ash melting point

Main points:
1. Origin:Specified to show where the raw wood has been sourced.• 1.1.3.1 Woody biomass, from forest or plantation, stemwood, broadleaf• 1.1.3.2 stemwood, coniferous • 1.1.3.3 stemwood, mixture of broadleaf and conifer • 1.1.1.1 whole trees (without roots), broadleaf• 1.1.1.2 whole trees (without roots), coniferous• 1.1.1.3 Short rotation coppice (without roots)• 1.1.1.5 Mixture of broadleaf, softwood and/or SRC (without roots)• 1.1.7 Woodchips derived from arboriculture
2. Traded form: woodchips, pellets, briquettes or firewood
3. Properties:– Particle size distribution e.g. P45– Moisture e.g. M40– Ash e.g. A1.5

So how can WhS help?
• WhS Newsletter• ‘Dummies Guide’• Woodheat Solutions: Approximate determination of moisture content of woodfuel using a domestic oven

WHAT NEXT?
17 & sponsored by:Led by the 22 March 2011
In South East England
• Build on WhS website to further network lessons learnt from project AND local experience– Case studies (to increase familiarity)– Guideline for considering woodfuel on a particular site (based on FC at
Bedgebury)• Further round of seminars for woodland owners and property
owners promoting RHI and Woodfuel WIG – particular focus on woodheat model
• Embed woodfuel knowledge in FC Woodland Officers (national training plan prepared under FC’s Woodfuel Implementation Plan)
• Continue to encourage use of woodheat via local plans etc• Local Projects:
– West Sussex Woodfuel Development Officer– Kent Downs Woodfuel Pathfinder– Surrey Hills Woodfuel Group– Bordon Whitehill Ecotown– TIMBER Project
• IEE2?

Under Woodheat Solutions
• Feedback request to all WhS contacts– Are you considering installing a woodheat system or
a woodfuel business?– What would help you most?
• Roll out of training pack• Workshop for woodfuel standards assessors• Newsletter 3: Introduction to Woodfuel
Standards• Newsletter 4: Key lessons from project• Final Reports
