“…The gas loading rates of the feed gases vary between 1.8 and 214.9 m 3 /(m 3 d) though most studies used gas loading rates in the range of 5-16 m 3 / (m 3 d) (Table 1). Higher loadings of around 70 m 3 / (m 3 d) were used by Strübing et al (2019Strübing et al ( , 2018Strübing et al ( , 2017 while Dupnock and Deshusses (2017) studied extreme high flow rates between 151.4 and 214.9 m 3 /(m 3 d).…”

“…In recent years, the media used for exsitu BM in TBR can be categorized into synthetic and non-synthetic. Non-synthetic liquid media originated mostly from digested wastewater sludge (Strübing et al 2017(Strübing et al , 2018(Strübing et al , 2019, digestate from biogas plant (Porté et al 2019) and pasteurized cow manure (Ashraf et al 2020;Dahl Jønson et al 2020;Sieborg et al 2020). The possibility to use non-synthetic and rather easily available media is a strong advantage of this process increasing its sustainability.…”

Power-to-methane technology is a promising solution to facilitate the use of excess variable renewable energy for biomethane production. In this approach, hydrogen produced via electrolysis is used to upgrade raw biogas, which can be subsequently used as fuel or stored in the gas grid. Ex-situ biomethanation is an emerging technology that could potentially replace conventional energy-intensive biogas upgrading methods and allow CO2 utilization for biomethane production. This work provides a comprehensive overview on the current status of ex-situ biomethanation with particular attention to trickle bed reactor. The review includes description of ex-situ biomethanation and summarizes previous works on this topic. The key elements related to operational conditions, efficiency, and microbiology of ex-situ biomethanation using trickle bed reactor are described here. Additionally, the review highlights the technical and economic issues that have to be addressed for future development and large-scale implementation of ex-situ biomethanation.

Comparative analysis of the effect of cell immobilization on the hydrogenothrophic biomethanation of CO₂

et al. 2021

Carbon capture and utilization (CCU) has been offered as a potential technological solution for mitigating the greenhouse gas emissions and climate change concern worldwide. Anaerobically carbon utilization has started to be in the agenda of researchers in recent years since this approach offers significant advantages such as use of catalysis reactions through environmentally friendly microorganisms under low temperature and pressure operational conditions. Moreover, a cleaner and more effective bioenergy production is realized in the form of biomethane. This study aimed to exploit the merits of cell immobilization in order to provide a stable hydrogenotrophic biomethanation process. For this purpose, two different immobilized bioreactors packed with plastic moving bed biofilm reactor (MBBR) and glass beads packing materials were comparatively investigated. To the best of our knowledge, these two immobilization materials were used for the first time for this purpose. Two different bioreactor configurations were compared for the performance parameters such as methane formation rate, H2 consumption and methane contents in the headspace. Methane content in the headspace of these bioreactors were measured to be 80 and 75% for MBBR bioreactor and glass bead bioreactors, respectively. In addition, methane formation rates (MFR) of 5.14 and 4.8 m3/m3/day were achieved in MBBR and glass beads bioreactors, respectively. Even though both bioreactor configurations performed highly efficient biomethanation of CO2, the statistical evaluation of the results indicated that MBBR performance was more favourable for hydrogenotrophic biomethanation. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.
