Biomethane production and grid injection: German experiences, policies, business models and standards (Chinese Version)

Biomethane offers the outstanding opportunity to substitute fossil natural gas as well as other fossil energy carriers in an extremely flexible way. Biomethane is interchangeable with natural gas – having equal physical and burning characteristics. It is produced from biogas by upgrading the gas to natural gas quality. Thus, any natural gas application can be served, and the natural gas grid can be used without any technical risk or challenge. Biomethane – in close conjunction with other renewable gases, such as hydrogen – is the basis for a long-term future use of the natural gas grids all over the world. In addition, biomethane is – compared to other renewable gases – a technology, which is available today and has been tried and proven for more than 20 years.

The report presents German experiences with policies, incentives, technologies, standards and business models for biomethane production and grid injection, and discusses implications and applicability for China. Suggestions for China include improving policies and regulations, establishing a biomethane monitoring system, setting industry standards, as well as introducing new testing and certification procedures.
