It has been reported that by enhancing the biogas content through purification, the cogeneration plant efficiency increased . Additionally, the enrichment of biogas led to reduced emissions, thus ensuring a more sustainable energy production route. The life cycle implications of the methanol production process revealed significant influences from electricity prices, electrolyser capital costs, and plant capacity factors . Furthermore, the study suggested that the methanol production process's competitiveness is expected to increase in the mid-term future, driven primarily by new European policy directions. van de Graaff highlighted the environmental superiority of green hydrogen over blue hydrogen, as the former is carbon-free and does not require CO2 storage. Further, the life cycle analysis pinpointed the need for advancements in essential processes for synthetic fuel production and stressed the potential synergy of local production combined with imported hydrogen or fuels.
