| description | The hydrogen economy is receiving more attention from the global energy industry, highlighting its crucial impact on global energy policies. In this context, the use of hydrogen in the synthesis of biomethanol is essential to the chemical industry and has great promise as a sustainable fuel for global transportation. This study evaluates a system that uses anaerobic digestion, high-temperature electrolysis, and biogas refining to produce biomethane and biomethanol. Novelties of the present study are heat integration and oxygen management between different subsystems, introducing liquified natural gas regasification and gas turbine cycles, and exergy-economic analysis and life cycle assessment using Aspen Plus and Simapro software, respectively. Economic analyses demonstrate lower levelized costs of natural gas and shorter payback periods for systems incorporating liquified natural gas and gas turbine cycles. Moreover, life cycle assessment results indicate a significant reduction of 53% in climate change impacts and 70% in resource use impacts for systems featuring liquified natural gas and gas turbine units. Exergy efficiency improves from 85.07% to 94.4%, largely due to the high exergy efficiency (98.06%) of the liquified natural gas and gas turbine units. By comparing different power sources, the wind turbine scenario demonstrates the potential for significant reductions in climate change and resource consumption compared to those of Poland’s electricity mix. |
