Energy efficiency of a hydrogen supply system using the reaction cycle of methylcyclohexane-toluene-hydrogen
In this research, we investigated an energy supply system based on hydrogen derived from renewable energy. We modeled the energy flow and efficiency of a system using the MCH-toluene-hydrogen reaction cycle (MTHR) by methylcyclohexane (MCH, C6H11CH3) and toluene (C6H5CH3). Electric power storage by...
