Biomethane is a renewable energy gas with great potential to contribute to the diversification and greening of the natural gas supply. Ideally, biomethane can directly be injected into the natural gas grid system. For grid injection, specifications such as those in EN 16723-1 shall be met.

- Accurate measurement of biogas impurities is crucial for compliance with biomethane specifications being developed by CEN/TC408, with a focus on proper sampling and transfer methods.
- Key factors in assessing sampling containers include permeation, leaks, sorption losses, and chemical reactions, with existing studies primarily evaluating siloxanes using various vessel types like bags and canisters.
- A combination of different sampling vessels is recommended to address the diverse impurities found in biogas, and further practical studies are necessary to improve measurement accuracy and reduce uncertainty.
The first reference gas mixtures of sulfur-free natural gas odorants that are traceable to the International System of Units (SI) have been produced and their compositions validated. These mixtures, which contain methyl acrylate and ethyl acrylate at amount fractions between 1.1 and 2.
