  Abstract

The demand for methanol as an alternative marine fuel is increasing. However, due to the high production costs and the instability of renewable energy supplies, green methanol currently accounts for less than 1% of the total methanol production. To address the challenges associated with green methanol, it is essential to improve the methanol yield and its energy efficiency in order to enhance the performance of the production process overall. This study proposes a novel green methanol production process that integrates solid oxide electrolyzer cell (SOEC)-based green hydrogen production with biogas partial oxidation. The proposed process minimizes carbon loss by injecting additional green hydrogen. As a result, this process achieved a methanol yield of 88.51%. Furthermore, by recovering waste heat from the biogas partial oxidation and methanol synthesis reactions and using it to produce steam, the energy efficiency of the proposed process was improved by 177% and 7% compared to the conventional e-methanol and bio-methanol processes, respectively.
