AIM: Inspire investment in wood-based heat generation from under managed woodlands in England, Croatia and Slovenia drawing on the experience gained in Finland and Austria. TIMEFRAME: 1 October 2008 to 31 st March 2011 Project Partners: Slovenian Forestry Institute Technical Research Centre of Finland Styrian Chamber of Agriculture and Forestry Slide 4 Lessons learnt (March 2011) 4 Starting point and objectives Starting Point: Increasing concerns about climate change and energy security Lots of undermanaged woodland Restoring sensitive woodland management delivers other benefits too, including jobs and biodiversity Objectives: Increase the number of woodheat projects in Slovenia, Croatia and the UK (15MW installed capacity) Facilitate the development of 10 major bio-heat projects in Slovenia, Croatia and the UK Increase the area of actively managed, privately owned woodland in Slovenia, Croatia and the UK ((4,500 ha) Raise the profile of CEN TS/335 standards amongst woodfuel suppliers and end users Raise the profile of woodheat projects amongst the general public, public sector decision makers, foresters and farmers Slide 5 Lessons learnt (March 2011) 5 Approach - in a nutshell! Engagement: Identify and build relationships with key decision makers able to facilitate the establishment of woodheat projects in Croatia, Slovenia and the UK Study tours: Identify a range of successful woodheat projects in Finland and Austria and use these to host study tours for key decision makers Best Practice: Develop regional guidance adapted from knowledge and experience gained in Finland and Austria Standards: Summarise and disseminate CEN TS/335 technical standards and highlight the importance of quality control during woodheat production. Training: Develop courses and materials for all those potentially involved in the woodheat supply chain Slide 6 Lessons learnt (March 2011) 6 Contrasting resources and population pressure CountryForest Area (million hectares) Total land mass (million hectares) % Forest Populatio n (million) Finland 23.03075%5.3 Austria 3.9847%8.3 Slovenia 1.2258%2.0 Croatia 2.75.742%4.5 South East England 0.271.914%8.3 (plus 7.5 in London) England 1.1138%51.0 UK 3.02412%61.2 EU (27)157.041937%497.6 Partner countries Slide 7 Lessons learnt (March 2011) 7 Indicative targets Slovenia, Croatia and England have significant resources of wood which is currently unharvested which could be used as woodfuel. Current plans are for: Croatia: to triple use of biomass by 2030, which equates to an increase of > 2,000,0000m 3 per year England: to bring an extra 2,000,000m 3 from currently undermanaged woods to the market by 2020, with at least 500,000m 3 coming from SE England Slovenia: estimates the production of woody biomass could be increased by at least 1,600,000m 3 Slide 8 Lessons learnt (March 2011) 8 Cultural differences: Austria and Finland have very strong cultures of wooduse and woodland management it is exceptional to see woods which are not actively managed Slovenia and Croatia also have strong wood culture though the levels of technical development of wood use are not as well developed. Part of the reason may be the high proportion of forest cover and resource relative to population: CountryFinlandAustriaSloveniaCroatiaEngland % forest cover 75%47%58%42%8% Area of woodland per person (ha) 4.30.50.6 0.02 Slide 9 Lessons learnt (March 2011) 9 Cultural differences: In England the wood culture is very different with: Most woods not being actively managed; A population which has lost touch with wooduse, who are not used to seeing managed woods and many of whom believe felling trees is bad for the environment. Slide 10 Lessons learnt (March 2011) 10 Woodland Ownership: Woodland ownership affects woodland culture and ability to adapt: -In Austria and Finland many people own woods but the area of ownership may be very small; -In Slovenia there have been major changes from state to private ownership in recent years -In Croatia the majority (80%) of woods are owned by the state -In England most woods are privately owned but while there are many woodland owners most of the woodland area is linked to estates or farms. (Woodland ownership has not been broken down into very small plots through inheritance as in Austria) Slide 11 Lessons learnt (March 2011) 11 Concerns about the evolving use of wood as a fuel As individual countries were all working hard to improve and make better use of our woodland resources and sharing experience between countries helps encourage lateral thought about how we can achieve our aims; However, there are concerns from some woodland owners and wood based businesses that the market for wood as a fuel will: compete for resources, increase raw material costs and endanger existing businesses; and use wood which would be better used as timber; particularly where the woodheat (and wood power) industry receives grant support. Slide 12 Lessons learnt (March 2011) 12 Current situation? Most woods in Austria and Finland are actively managed There is an embedded culture of woodfuel use both for domestic and community heating High technology developments of woodfuel use in Austria Pragmatic technology developments of large scale woodfuel use in Finland Slide 13 Lessons learnt (March 2011) 13 Current situation: Didcot Power Station Many woods in SE England have not been actively managed for decades, mainly due to loss of markets for wood products There is also a general energy culture based around large scale and centralised power stations Slide 14 Lessons learnt (March 2011) 14 Woodheat in Finland FIRST IMPRESSIONS! Slide 15 Lessons learnt (March 2011) 15 Everything is managed High silvicultural standards A can do culture A long term view Community Professionalism Slide 16 Lessons learnt (March 2011) 16 District heating is common Central woodheat plant a Toivakka provides heat through a heat main to properties in the centre of the village Slide 17 Lessons learnt (March 2011) 17 Woodfuel reception Woodfuel is delivered into a large barn (large capacity allows for extreme conditions when fuel delivery would be impossible). Walking floor moves fuel left to right & Large capacity augers deliver woodchips to boiler Whole system is robust and built to last Slide 18 Lessons learnt (March 2011) 18 Chip store to boiler Large capacity augers, less prone to jamming and long lasting Woodchip quality, included more shades and fines than seen in Austria BUT system was designed to cope Slide 19 Lessons learnt (March 2011) 19 Boilers Boilers tended to be large in size (compared to Austrian equivalent) but were running at high load for long periods in winter Wet ash disposal systems were the norm Slide 20 Lessons learnt (March 2011) 20 Why? Very cold winters mean that significant amounts of heat are needed for extended periods; While in southern Europe failure of the boiler might be inconvenient in Finland it could be life threatening; Whole system of wood to warmth complements to situation Slide 21 Lessons learnt (March 2011) 21 Woodfuel harvesting Fuel for local woodheat systems was often derived from subsidised first thinning operations designed to improve the quality of the retained timber trees. Usually highly mechanised modern harvesters possible due to terrain and low density of retained trees but also motor manual Slide 22 Lessons learnt (March 2011) 22 Dont burn water! When trees are first felled they are approx. 50% water (by overall weight). Seasoning for a year will normally reduce this to 30%. Energy value increases by about 8% Often whole trees are used for woodfuel, but rigorously seasoned. Waterproof paper helps prevent rewetting through snow melt Slide 23 Lessons learnt (March 2011) 23 Use the whole resource Sophisticated specialist machinery is used for contract chipping. Giant chipper in operation chipping seasoned whole trees derived from first thinnings. Loading woodchips directly into walking floor lorry (and trailer) for delivery to local woodheat plant Slide 24 Lessons learnt (March 2011) 24 Make use of existing equipment Local scale woodchip production (again using whole trees). Note use of: agricultural tractor Silage/corn trailer Woodchiper powered by tractor Slide 25 Lessons learnt (March 2011) 25 Innovate Delivery of woodchips using simple (chain driven) walking floor lorry in Finland. Walking floor chip store allows easy access for a range of delivery vehicles and has large capacity Slide 26 Lessons learnt (March 2011) 26 Innovate Having difficulty building a woodchip bunker which is versatile enough to allow delivery by a range of tipping trailers? Consider fitting hydraulics to the roof so that it lifts vertical! Slide 27 Lessons learnt (March 2011) 27 Pay for energy Weight and moisture content have the greatest impact on energy value. Test energy value using domestic scales and oven Slide 28 Lessons learnt (March 2011) 28 Engage the local community Forestry training starts early in Finland! Local children learning how their classroom is kept warm Slide 29 Lessons learnt (March 2011) 29 Overall message: There are major opportunities for entrepreneurial woodland owners and rural businesses to add value to low quality wood by converting it into the much more valuable heat. Particularly if this can be carried out locally using existing resources Slide 30 Lessons learnt (March 2011) 30 Consider the latest technology Finnish technology introduced to England: (Valtra tractor, Botex 8m boom and Keto harve
