Abstract: Biomass energy is a renewable clean energy. Focusing on biomass energy products and according to their different physical states, the national standardization system of biomass energy is proposed in the course series on the basis of investigation of the international standardization of major products. The progress of biodiesel standardization is reviewed in this paper. On the basis of analyzing the status of international biodiesel industry development, the main standards of biodiesel products in the world are introduced. The specifications of biodiesels from different countries are compared each other. It is suggested that the standard system of national biodiesel products should be established quickly according to the present situation of China biodiesel industry. The draft of biodiesel standards could be expedited by the way of adopting international standards.

Key words: biomass energy, biodiesel, standard system
