Prospects of China’s biogas: Fundamentals, challenges and considerations

摘要

This article focuses on the background and current situation of various levels of biogas generation in mainland China. These levels are categorised as rural household, agricultural engineering and industry-based engineering generations. To analyse and forecast China’s biogas generation, the Hubbert forecast model was discussed for Chinese provinces. This model was initially applied to the petroleum research industry and can be implemented to biogas prediction. The results validate that total biogas generation may not be achieved in the coming years because of low rural household production and thus contradicts the previous target set by the government. Enhanced bio-natural gas yield is one of main objectives of China’s energy sector, which targets 300 × 10sup27/sup msup3/sup of biogas by 2030. This work evaluates the opportunities and challenges in China’s biogas production market. It also provides detailed descriptions of biogas policy and development, national subsidy framework, foreign investments and future perspectives for the establishment of pilot-scale biogas generation.
