Abstract: Alternative fuels for transportation are gaining momentum in the global market. Current technology to produce ethanol based on sugar and starch crops is not sustainable in the long term. Second generation technologies based on cellulose-based feedstocks use non edible crops and have a positive energy balance. Notwithstanding, they are not at commercial stage, requiring more research and development (R&D) to help overcome technological barriers. Many countries recognize the value of collaboration to increase benefits and reduce costs of research, and some have in place policy instruments to promote this practice. Given the policy relevance, the monitoring of the evolution and patterns of international collaboration in R&D is in place. We carry out a bibliometric analysis by building a publication dataset drawn from the ISI Thompson Science Citation Index database covering the period between 1970 and 2006. We identify the most productive institutions and countries, their historical evolution and interaction patterns.
