Framework conditions and market potentials for the diffusion of innovative small-scale wood pellet systems

• More than 85% of all dwellings in the European Union are currently being heated by single-house systems. At the same time significant technological progress, cost reductions and increasing consumer awareness related to modern small-scale bioenergy systems (SSBS) have occurred in recent years. Taken together, SSBS could make a substantial contribution to the heat and electricity requirements in the not-too-distant future and, by substituting for less benign energy technologies and fuels, also to a more sustainable energy supply system. Despite the remarkably increased levels of comfort and reduced environmental impact offered by today´s SSBS, however, their widespread diffusion is still at its very beginning. Framework and market conditions and the overall merits of SSBS systems need to be properly understood by policy-makers for a suc-cessful promotion policy addressing these technologies. Technology diffusion models can help to better understand the diffusion dynamics and long-term market potentials, and the effectiveness of drivers and barriers that influence the adoption decision process. This paper first summarises recent technological, socio-economic and institutional trends relevant for SSBS adoption, and reflects on research results from other studies in this field regarding perceived image, comfort levels, reliability, and ways of use of modern small-scale bioenergy technologies in Europe. Second, it contains a limited compara-tive analysis of the direct and indirect external costs and benefits of modern bioenergy-based versus other heating technolo-gies at the small scale. Third, the usefulness of various economic diffusion modelling approaches is discussed, also with a perspective on studying modern SSBS in the light of data availability restrictions
