The bumpy road of biomass gasification in the Netherlands: Explaining the rise and fall of an emerging innovation system

In this paper, the concept of System Functions of Innovation Systems is applied to provide an explanation of the success or failure of an emerging technology, i.e. biomass gasification, with empirical data on the evolution of this technology in the Netherlands during 1980-2004. A new list of System Functions has been developed lately and is used to identify the most relevant events in the evolution of the Biomass Gasification Innovation System. We show that a structural misalignment occurred between the institutional framework within which the technology could have been developed and the technical requirements of the technology. Finally, the absence of System Functions such as the guidance of the search, resource allocation and advocacy coalition explains the failure of this technology over time.     

Landowners’ willingness to promote bioenergy production on wasteland − future impact on land use of cutaway peatlands

Landowners are the key players in bioenergy production on wasteland; such as cutaway peatlands. In this study, the landowner’s interest to use cutaway peatlands for bioenergy production was investigated using a survey and GIS (Geographic Information Systems) methods in an area in South Ostrobothnia, Finland. The focus was to identify which different bioenergy production chains are preferred by the respondents: combustion, gasification or biogas production from agriculture, energy-willow short-rotation forestry or forestry based energy crops. Also, the influence of personal environmental values on the selection was measured and the future impacts and barriers for the land use were assessed.Afforestation was the most popular after-use method among the landowners. The next most favorable method was energy crop cultivation but it was highly dependent on economic profitability and subsidies. Currently, approximately 8.2% or 500 ha of the total peat extraction area could be used for bioenergy production in the region by 2035. Based on the survey, forest based biomass is the best option if bioenergy is to be produced. The next choice was agro biomass and the least favored plant was willow. This study suggests that the biggest cutaway peatlands will be converted to forest energy in the future. Suggestive results were that the owners with high environmental values are especially interested in agro biomass growing and the landowner having a distant home place does not have a negative influence on bioenergy production. Altogether, land use and biomass production of cutaway peatlands is connected with the demands of the Finnish bio-economy.
