In recent years, with the soaring crude oil price due to shortage of supply and rising demand on environment protection, the RD and commercialization activities were highly invested, especially in US, Europe, Japan, Brazil and etc. As an emerging giant, China is increasingly suffering from high dependency on imported crude oil due to soaring vehicle sales and also the growing demand on oil. Meanwhile,increasing consumption of oil and quick industrialization are leading to heavy pollution and exhaustion of greenhouse gas. Therefore, China is highly expected to rely on Alternation Fuel Vehicles that may secure national energy supply by reducing the dependency on oil, promote environment protection and sustainable development,and also bring a great opportunity of leaps on technology for domestic automakers.However, Alternative Fuel Vehicles are highly diverse in technologies and also characterized by different levels of technology maturity, cost, fuel, cleanness and etc.Furthermore, the commercialization of Alternative Fuel Ve
