Abstract [en]

In recent years, China has suffered from its air pollution and climate change especially in large cities like Beijing. Many researches proved that the air pollution and climate change has close connection with fossil fuel combustion in industry and transportation. Additionally, energy depletion and energy security problems are getting more serious day by day. Hence, it is necessary to establish a renewable, environmental-friendly, and high-efficiency energy system and pay more attention on biofuel development and implementation.

At present, there are mainly two generations or five kinds of biofuels active in the Chinese local market: the first generation of biofuel based on food like corn-based ethanol and Waste Cooking Oil (WCO) based biodiesel; the second generation of biofuel based on non-food material like cellulosic ethanol, cassava ethanol and jatropha biodiesel. This report conducted research on the development situation, policy environment, GHG emission and energy efficiency of the two generations of biofuels, and discussed the future pathway of sustainable development of liquid biofuels in China.

The key finding of this thesis is that biofuel has its appropriate time in China. Biofuel is a renewable and environmental friendly energy resource because of the lower life cycle GHG emission (at most around 92% GHG reduction compared to fossil fuel) and good energy efficiency (95% at best). However, only WCO biodiesel and cellulosic ethanol be considered as the most recommended biofuel after a comprehensive analysis of the five kinds of biofuels. At present, a fully implementation of biofuel in China is well in sight. In the future, focus should be concentrated on completing the recycling and collecting system of raw material, reducing production cost, and strengthening cooperation between research institute, production enterprise and sales companies.
