Conclusion This study aimed to design energy storage systems (ESSs) using hydrogen and methanol as energy storage media and analyze their long-term and large-scale applicability from a thermodynamic and economic perspective.
The methanol energy storage system (MESS) can be an alternative for long-term and large-scale energy storage because methanol is a liquid at ambient pressure and temperature, and thus, its storage conditions are mild . In this system, methanol synthesis and decomposition processes are installed to use methanol as an energy storage medium.
In this system, methanol synthesis and decomposition processes are installed to use methanol as an energy storage medium. MESS has the advantage of a cheaper storage tank, even though the system configuration is complex, and additional energy should be supplied to meet the reaction conditions.
This study designed and analyzed a hydrogen energy storage system (HESS) with hydrogen storage pressures of 200, 350, and 700 bar, and a methanol energy storage system (MESS) from thermodynamic and economic perspectives. MESS showed lower energy efficiency (27.0 %) than the 200-bar HESS (28.6 %) due to compression and reactor heating requirements.
In addition, methanol has the additional advantage of being a universal chemical and fuel feedstock, thus representing the ideal candidate for not only chemical energy storage, but also for substituting fossil raw materials.

Synthesizing methanol from carbon dioxide and electrolytic hydrogen provides such ultra-long-duration storage in liquid form. Carbon dioxide can be captured from Allam cycle turbines burning methanol and cycled back into methanol synthesis.
