At present, biogas can not be compressed. It's not a technical problem, it's mainly a low economic value. The unit economic value of biogas is relatively low, and it can not be stored in high density.
For example, when the biogas is compressed to 50 times, the carbon dioxide in it is easy to liquefy or solidify in a closed steel cylinder, so compressed liquefied biogas is rarely used in the market. Due to the limited market factors and other factors, the large-scale compressed storage of biogas can not be realized at present. It is believed that in the near future, biogas purification and compression storage will be widely used in the market.
Biogas is a kind of combustible gas produced by microbial fermentation under certain temperature, humidity and pH in anaerobic environment. Because this gas was initially found in swamps, lakes and ponds, it is called biogas. Biogas contains a variety of gases, the main component is methane (CH4). It's a good clean fuel.
