Incorporating energy storage solutions like methanol helps bridge the gap between energy generation and consumption. By storing excess energy produced during peak generation hours, methanol can later be used to generate electricity when demand surges or when renewable production dips.
Energy storage for multiple days can help wind and solar supply reliable power. Synthesizing methanol from carbon dioxide and electrolytic hydrogen provides such ultra-long-duration storage in liquid form.

Methanol has emerged as superior chemical energy storage system. Methanol production from CO 2 and renewable energy is the most efficient and therefore the only way to realize such storage economically on a large scale.
Enter the methanol battery – the Swiss Army knife of energy storage solutions. Over 50% of renewable energy projects now consider methanol-based systems as viable alternatives, according to a 2023 International Energy Agency report.
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.
26. 27. Energy storage for multiple days can help wind and solar supply reliable power. 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.
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 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.
The multiobjective design of hybrid energy storage systems within the green methanol process ensures improved sustainability.
In order to understand methanol better as a long-duration energy storage option, there are several urgent research needs. The effects of flexible methanol synthesis on catalyst behavior, efficiency, and wear-and-tear should be demonstrated. More experience is needed on methanol synthesis with carbon dioxide rather than carbon monoxide.
