Explaining the success of emerging technologies by innovation systems functioning: the case of biomass digestion in Germany

We examine the view that the success of emerging technologies may be understood using a technological innovation systems analysis, drawing on a system functions approach. This is done in the context of a case study of the successful diffusion of biomass digestion technology in Germany. We show that that all system functions that are claimed to be important within the innovation systems approach are present in the German Biomass Innovation System; and that these system functions positively interact leading to virtuous cycles and a rapid growth of the German Biomass Digestion Innovation System.
