Abstract: Biomass energy is a renewable and clean energy. Focusing on biomass energy products and according to their different physical states,the 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 biomass solid fuel standardization is reviewed in this paper. On the basis of analyzing the status of international solid biofuel industry development, the main standards of solid biofuel in the world are introduced. The specifications of solid biofuel from different countries are compared each other. According to the present situation of China solid biofuel industry and standardization, it is suggested that solid biofuel standards and service system should be established and perfected in order to form full market and standard system including production of solid biofuel, burning appliance and customer service.

Key words: biomass energy, standard system, solid biofuel
