Austrian experiences with the introduction of pellets as a fuel Christian Rakos, Energieverwertungsagentur Juha Rautanen, Motiva
Sales of domestic pellet boilers in Austria Prognose Quelle: Pelletsverband, 2000
General factors that have supported diffusion kick off • Rapid advances in technology and design • Consumer interest - the first comfortable wood heating systems • Generally positive attitude towards wood as domestic fuel
Characteristics of the Austrian market for pellets • It is very young: emergence of pellets 1994 • significant start up problems (as with any new market) • expansion despite relatively poor economic frame conditions • pellets created high enthusiasm among public and businesses • two markets: • boilers for single family houses • boilers for blocks of flats
Main problems for market introduction • 1) Pellet supply • 2) Pellet delivery • 3) Pellet storage at the customer • 4) Pellet boiler • 5) Installation and service
1) Pellet supply • Supply security: major concern of potential customers! • Quality of pellets: low dust content and mechanical stability is fundamental for small boilers • high dust content decreases boiler efficiency and causes operation failure • pellets from waste wood had disastrous effects: slagging of boilers, discontinued operation
2) Pellet delivery • Delivery vehicles must evacuate the dust simultaneously by blowing in pellets • must have adequate pumping force • should be able to weigh the pellets delivered • standardised connections to the house inlet necessary • drivers must be trained (e.g. to inspect the storage room)
3) Adequate pellet storage room necessary • dry • no electrical installations (danger of dust explosion) • solid walls • dustproof door
4) The pellet boiler • Many companies jumped on the pellets train too fast • unreliable devices were introduced into the market (“testing in the market”) • frequent operational problems - negative impact on the image of heating with pellets • Since 1998 major Austrian equipment producers offer fully reliable boilers
Typical technical problems: • Overheating of the boiler: slagging of ashes • High temperature corrosion • ash deposition in poorly designed heat exchangers: up to 50% efficiency loss • ash deposition in the burning zone • serious back-burn problems • unreliable pellet delivery from the storage room to the boiler
5) Installation and service • Installers have no experience with pellets • consequently they prefer to sell oil boilers • frequent mistakes in installations lead to operation problems • efficient and fast service is still missing (Service network is expensive) • new strategy of most advanced producers: service contract is sold with the boiler, 1 full service every year
6) Education of other related professionals • Architects: design of pellet storage and boiler room, convenient delivery of pellets • Planners of heating systems • Chimney cleaners: these could provide service of boilers - new business opportunity! Chimney cleaners could be a strategic partner: they know the old boilers that need to be replaced and can promote pellet boilers
Economic situation • Pellet price: approx. 150 EURO/t incl. delivery and VAT (30 EURO/MWh) • Pellet boiler: approx. 10.000.- EURO incl. automatic storage retrieval and VAT • Subsidies: approx. 2000 - 3000 EURO depending on region • Reference cost for extra light fuel oil: approx 30 EURO/MWh; oil boiler: 4400 EURO incl. tank
How to introduce pellets successfully I • Create public awareness for pellets • Demonstrate reliable pellet delivery • Establish strict quality standards for pellets • Establish strict quality criteria for pellet boilers (high efficiency, low emissions and reliable operation) • poor boilers are a greater problem for long term market development than expensive boilers!
How to introduce pellets successfully II • Establish investment subsidies for boilers to kick start market development • Keep poor pellet boilers out of the market (e.g. by excluding equipment that does not meet standards from subsidies) • In DK level of subsidy was directly linked to emission standard - rapid improvements • Subsidies for education of professionals, measures to ensure quality, public relations
How to introduce pellets successfully III • Establish and test logistics for pellet delivery - ensure there is an immediate impression that supply is no problem • Educate and prepare professionals - especially installers before advertising • Establish a few demonstration plants that represent the state of the art for educational purposes (preferably by experienced technical experts)
Which market should be addressed first I ? • Large scale heating plants • +/- not sensitive to pellet quality • - very low prices of competing wet biofuels • blocks of flats • + lower specific costs of the boiler • + fewer actors that can be addressed directly • + less resources for fuel logistics and service network • + can become a niche for developing the structures to support diffusion in the domestic sector
Which market should be addressed first II ? • individual housing • + have higher conventional fuel costs than larger users • + large market • + option: pellet stoves as “low barrier system” • - high marketing costs • - high initial requirements for fuel supply and service logistics • - high requirements for education of professionals
The Austrian choice • Individual houses: this choice was made by industry, that was used to deliver to this market. Mainly central heating systems, less stoves • Selected attempts to introduce pellets into the large buildings segment were rather successful locally • Barrier: construction companies do not know qualified planners that realise pellet system
Summary I • The introduction of pellets into the heat market requires a comprehensive and complex approach • problems that are not managed promptly can seriously affect the diffusion process • It needs a dedicated actor (institution) that co-ordinates and manages pellet introduction - “system building” is necessary
Summary II • One company alone cannot finance system building as all others will take advantage of this • in Austria two organisations have been created for this purpose: Bioenergy Austria and Austrian Pellet Association • public co-financing is very important for such initiatives • investment subsidies for pellet boilers is necessary to overcome high transaction costs and perceived risks of new technology
