Abstract The transition towards renewable energy production will not occur without the involvement of entrepreneurs who dare to take action amidst uncertainty. In an earlier article [1], a conceptual model was introduced for analyzing how perceived uncertainties influence the decisions and actions of entrepreneurs involved in innovation projects that aimed at developing and implementing renewable energy technologies. In this article, the conceptual model is applied to stand-alone biomass combustion projects in the Netherlands. Although none of the biomass combustion projects has been abandoned, some entrepreneurs clearly have more difficulty to turn their project into a success than others. To create insight into the underlying dynamics of these projects, the article analyzes what types of positive or negative interaction patterns occur over time between (internal or external) factors in the project environment, perceived uncertainties, motivation and entrepreneurial action and how these patterns can be stimulated or prevented. The results provide several lessons to take into account when designing policies for stimulating the development and implementation of biomass combustion.
