“…New methods have also been developed specifically for biomethane. For example, in a recent article [37], three methods are proposed for the analysis of NH 3 in biogas or biomethane matrices for amount fractions at an upper limit level of 10 mg m −3 as specified in EN 16723-1:2016. Three spectroscopic analytical methods, Fourier transform infrared spectroscopy, cavity ringdown spectroscopy, and optical feedback cavity-enhanced absorption spectroscopy, were investigated at three NMIs (NPL, VSL, and RISE, respectively).…”

Biomethane may contain trace components that can have adverse effects on gas vehicles performances and on the pipelines when injected in the gas grid. Biomethane quality assurance against specifications is therefore crucial for the integrity of the end-users’ appliances. Analytical methods used to assess biomethane conformity assessment must be validated properly and possibly, new methods specifically for biomethane should be developed. This paper provides an overview of the biomethane quality assurance infrastructure and the challenges faced with focus on sampling, analysis methods, reference gas mixtures, and performance evaluation. Currently, requirements for analytical method validation and fit-for-purpose assessments do not exist for biomethane. The industry is in urgent need of a protocol to evaluate the fit-for-purpose of methods in a harmonized manner. Reference gas mixtures to check the accuracy of the instrument and to determine the traceability of the measurement are also urgently required.

“…For the analysis of NH 3 in biogas the procedure is similar only in that case also the interfering signal due to carbon dioxide needs to be subtracted. More details can be found in upcoming paper which also describes the analysis of NH 3 in biogas by two other spectroscopic techniques, namely Fourier Transform Infrared (FTIR) Spectroscopy and Optical Feedback Cavity Enhanced Absorption Spectroscopy (OF-CEAS) [118].…”

Metrological services from National Metrology Institutes related to energy gases have been supported by the programme of key comparisons of the Gas Analysis Working Group of the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology since its conception in 1993. Most of the key comparisons have been performed on natural gas composition measurement, which is key to the calculation of natural gas properties, thereby facilitating fiscal metering and the trade in natural gas. In the recent years, non-conventional energy gases and natural gas substitutes, such as refinery gas and biogas have been addressed. The paper gives an overview over the achievements in this area from the first key comparison (CCQM-K1) onward and outlines the current challenges to the metrological community. The ongoing energy transition towards renewable energy gases is at the centre of these challenges. The associated emerging challenges primarily concern the measurement of the concentrations of impurities, such as silicon in biomethane and upgraded biogas, carbon monoxide in hydrogen, and many others. The paper presents the first results of the development of measurement standards and methods for impurities in biogas, biomethane and hydrogen and the implications for the programme of key comparisons.

“…Work was carried out in a pilot plant to clean and recover real biogas from anaerobic digestion using the chemical absorption method [30]. A 29-month stability study of reference gas mixtures of 10 µmol mol −1 ammonia in methane and synthetic biogas is also reported [31]. Research carried out the processing of a mixed stream of gases with a typical biogas composition using a gas separation membrane with the aim of producing a stream of purified biomethane [32].…”

In view of the increasing demand for clean energy and the growing awareness of environmental sustainability, a bibliometric study examines the various facets of renewable natural gas (biomethane). Sustainable fuels are gaining importance as an alternative to fossil fuels because they are renewable and can reduce greenhouse gas emissions. In addition, an overview of the use of biomethane was compiled for Brazil. The country was chosen because it is the authors’ home country. These emerging energy sources have the potential to play a critical role in the transition to a cleaner, more sustainable and cost-effective energy landscape, thereby reducing environmental impact and strengthening the resilience of our energy future.
