Methanothermobacter has been pivotal in elucidating the biochemistry of hydrogenotrophic methanogenesis. These microbes generate cellular energy to grow by producing methane from hydrogen and carbon dioxide. Recently, this physiological trait was adopted for biotechnology in power-to-gas processes to store renewable electric energy in form of methane in the natural gas grid. We established a genetic system and a genome-scale metabolic model for Methanothermobacter (Microbe of the Year 2021) to support further technology advancement and implementation for large-scale production of renewable methane.

“…8 Recently, the development of an “ ex situ ” methanation process with a pure culture of a thermophilic evolved strain of Methanothermobacter thermautotrophicus , has been successfully commercialized by Electrochaea, for the conversion of CO 2 from biosources or industrial exhaust. 9 This has paved the way for the use of methanogens in “Power-to-methane” strategies.…”

“…When the methane concentration increases after removing CO 2 and other impurities, the upgraded biogas is called biomethane. Biogas upgrading technologies can be installed in almost any biogas production sector: wastewater treatment facilities, waste management facilities such as landfills, and agricultural anaerobic digestion plants, whether existing or newly built [17,18]. Biomethane with a high CH 4 concentration meets natural gas quality and, as a renewable fuel, can be broadly used as a substitute for fossil fuel in transportation, heating, and electricity generation [19].…”

While energy-related sectors remain significant contributors to greenhouse gas (GHG) emissions, biogas production from waste through anaerobic digestion (AD) helps to increase renewable energy production. The biogas production players focus efforts on optimising the AD process to maximise the methane content in biogas, improving known technologies for biogas production and applying newly invented ones: H2 addition technology, high-pressure anaerobic digestion technology, bioelectrochemical technology, the addition of additives, and others. Though increased methane concentration in biogas gives benefits, biogas upgrading still needs to reach a much higher methane concentration to replace natural gas. There are many biogas upgrading technologies, but almost any has methane slip. This research conducted a life cycle assessment (LCA) on membrane-based biogas upgrading technology, evaluating biomethane production from biogas with variable methane concentrations. The results showed that the increase in methane concentration in the biogas slightly increases the specific electricity consumption for biogas treatment, but heightens methane slip with off-gas in the biogas upgrading unit. However, the LCA analysis showed a positive environmental impact for treating biogas with increasing methane concentrations. This way, the LCA analysis gave a broader comprehension of the environmental impact of biogas upgrading technology on GHG emissions and offered valuable insights into the environmental implications of biomethane production.
