Renewable natural gas

Technology

Renewable natural gas

Country

Germany

Application in details

Renewable compressed natural gas (CNG) is made from animal waste, agricultural crops and crop residues, and food waste.

Since these feedstocks decompose naturally over time, using them to replace carbon-based fossil fuels means that overall emissions can be reduced.

The production process is as follows:
1. Biogas is produced from feedstock (animal and vegetable waste, etc.) using an anaerobic digestion process.
2. The biogas is then processed to ensure that it meets industry standards and converted into DSM.
3. Finally, the DSM is injected into the gas grid.

Scalability

Shell aims to start large-scale production of liquefied gas with biocomponents for refueling trucks within about two years. The company said that trucks using such fuel can drive 1500 km without refueling
