The same legislation and requirements that regulate the use of natural gas also apply to processed biogas, primarily biogas that contains methane. Processed biogas is delivered to natural gas pipework, filling stations or usage sites.
If the methane content of biogas is 80% or more, the storage limits are the same as with natural gas.
Tukes processes biogas in accordance with the Natural Gas Decree in the following cases:
- biogas pipelines outside a plant, the interface is usually a biogas processing unit.
- public biogas filling stations in connection with a biogas plant
- biogas recovery from a landfill. In landfills, the recovery pipeline itself is not within the scope of natural gas regulations. Instead, the application starts with the gas manifold after the recovery pipeline.
