In this paper we focus on stakeholder views around the development of advanced biofuels from microalgae. Research for the development of microalgal-derived biofuels was initiated by the US Department of Energy (DOE) more than 30 years ago. However, interest in this eco-innovation has been growing significantly over the last five years in various countries. The high productivity of algae indicates that algal biofuels could contribute to reduce our dependence on fossil fuels while avoiding the undesired impacts of first generation biofuels. There are still numerous challenges that need nevertheless to be addressed. The aim of this paper is to explore stakeholder perceptions of the current barriers and opportunities associated with this promising emergent technology. (C) 2011 Elsevier Ltd. All rights reserved.
