Comprehensive analysis of biomass feed power generation utilizing low-temperature LNG for hydrogen storage applications

This study investigates the integration of low-temperature liquefied natural gas (LNG) with biomass-fed power generation systems, focusing on its dual role in enhancing energy conversion and supporting hydrogen storage. By leveraging the cryogenic potential of LNG, a novel hybrid configuration is proposed in which LNG cold energy recovery is thermally coupled with biomass gasification, enabling simultaneous power generation and hydrogen production. A comprehensive thermodynamic model is developed and analyzed to evaluate the system's performance. The results show that the proposed system achieves energy and exergy efficiencies of 19.8 % and 12.6 %, respectively, demonstrating a significant improvement in energy utilization compared to conventional setups. Exergy analysis identifies the gasifier as the primary source of irreversibility, contributing approximately 7391 kW to the total exergy destruction. Additionally, parametric analysis reveals a linear relationship between combustion chamber inlet temperature and both the electrical and total cost rates, highlighting economic trade-offs and optimization potential. The system also shows scalability and adaptability for future integration with renewable hydrogen infrastructure. These findings confirm the technical viability and sustainability of the proposed approach, offering a promising pathway toward low-carbon energy systems and efficient hydrogen storage solutions.
