Abstract: By reviewing the development of household biogas in China, one of the key factors which impeded the use of biogas in northern China was noted - how a biogas digester lives through the winter. In order to solve this problem, a model named ||Four in one|| has been proposed by some researchers. In this paper, this model, including its structure, technical features, and benefit was introduced and analysed. And finally, with some statistics data, a conclusion was reached that the ||Four in one|| model has effectively promoted the development of biogas in northern China as well as providing valuable experiences for other developing countries.

Keywords: household biogas; energy; rural energy; China; developing countries.
