Air Liquide recently announce that it has invested and will operate its first biomethane production unit in China by the end of 2022. Located in Huai’an City, in the Jiangsu Province, the unit will have a production capacity of 75 GWh per year.

The biomethane unit will produce biogas from agricultural and livestock waste coming from local farms and purify it into biomethane. With a total production capacity of 75 GWh/y, the unit will inject the biomethane into the city gas grid to be used for household consumption and also generate electricity for its own consumption and injection into the electrical grid.

The digestate, a byproduct material resulting from the biogas production, will also be processed to produce bio-fertilizers.

Biomethane has a high potential in China in particular as the Chinese government supports projects promoting the valorization of waste as part of its financial plans for the development of rural regions.
