4. What is a gas analysis?

A gas analysis is a crucial part of the quality control process for injecting biomethane. By taking samples and conducting laboratory analysis, it is determined whether the gas meets legal requirements and can be safely injected. The analysis examines the methane content, CO₂ levels, sulfur and other components that may affect gas quality. Additionally, the physical properties of the biomethane, such as the Wobbe index, are assessed.

Sampling process

Sampling is conducted at the injection site following a strict protocol to ensure reliable results. The samples are then analyzed by a certified laboratory, such as Kiwa's chemical analytical laboratory, where the exact composition of the gas is determined. Any deviations are reported, allowing you to make timely adjustments to stay compliant with regulations.

Mandatory periodic gas analyses

To ensure consistent biomethane quality, periodic analyses are mandatory. The network operator specifies when and how often these analyses must be conducted. Refer to the previous page for an overview of the different periodic gas analyses.

Additional inspections

It may also be beneficial to conduct additional checks to prevent unforeseen issues. By doing so, you can avoid unexpected problems and continuously guarantee quality, contributing to a safe and sustainable gas supply.
