Methane electricity generation is an important measure for constructing the green environment protection engineering,with great potential for development.

The application and prospect of methane power generation technology and methane fuel cell;

As a short-term objective,biogas power generation and vehicle biogas production will be increased continuously;and as a long-term objective,biogas fuel cell technology and biogas chemical industry should be developed to improve the utility value of biogas.

PER calculation of a biogas engine driven heat pump system;

Biogas engine-driven heat pump(BHP)not only has the same functions of compression heat pump,but also can utilize the waste heat recovery from biogas engine.

This paper reviewed biogas combustion characteristics,modification of biogas engine,application of biogas power generation technology in and out of china and application of the fuel cell.
