Challenges for introducing upgraded biogas (biomethane) to the existing Danish natural gas grid

摘要

Introduction In the years to come it is expected that a significant amount of biomethane will be introduced to the existing Danish natural gas grid. Locally, the amount of biomethane injected into the grid will often exceed the amount utilised in the low-pressure PE-pipelines. Therefore, it will be necessary to admit the biomethane into the steel pipelines supplying the local networks with natural gas.
