“…The basis for the work carried out is the standards ISO 14040 and ISO 14044 [38,39]. The widely used ReCiPe method (ReCiPe Midpoint (H) V1.13) was selected as the life cycle impact assessment method [8,18,19,22,29,40,41]. To provide a comprehensive overview of the ecological impacts of the systems studied, all midpoint impact indicators were considered, with this paper addressing the 11 presented in Table 2.…”

“…Collet et al as well as Parra et al have investigated the impact of the operation of different concepts with chemical methanation [7,8]. Biological methanation plants with stirred tanks were investigated within the P2G-BioCat project and by Goffart De Roeck et al [29,30]. To date, there are only two publications that have examined the ecological consequences of a trickle-bed bioreactor, whereby no future scenarios were analyzed [31,32].…”

The fluctuating nature of renewable energies results in the need for sustainable storage technologies to defossilize the energy system without other negative consequences for humans and the environment. In this study, a pilot-scale trickle-bed reactor for biological methanation and various scale-up scenarios for 2024 and 2050 were investigated using life cycle assessment. A best- and worst-case scenario for technology development until 2050 was evolved using cross-consistency analysis and a morphological field, based on which the data for the ecological models were determined. The results show that the plant scale-up has a very positive effect on the ecological consequences of methanation. In the best-case scenario, the values are a factor of 23–780 lower than those of the actual plant today. A hot-spot analysis showed that electrolysis operation has an especially large impact on total emissions. The final Monte Carlo simulation shows that the technology is likely to achieve a low global warming potential with a median of 104.0 kg CO2-eq/MWh CH4 and thus can contribute to decarbonization.

“…More generally, existing life-cycle analysis of methanation indicate that the Global Warming Potential (GWP) of e-methane produced with renewable energy sources is smaller than fossil natural gas [11,12]. Benefits of e-methane on GWP are even larger if the methanation is done through catalysts through captured CO 2 rather than from biomass [13,14].…”
