6 FAQs about [Energy storage hydrogen methanol]

Can a hybrid hydrogen-battery energy storage system improve green methanol production?

Comprehensive Design of Hydrogen-Battery Hybrid Energy Storage System in Green Methanol Production from Economic, Safety, and Resilience Perspectives This study proposes a multiobjective optimization for a hybrid hydrogen-battery energy storage system based on hierarchical control and flexible integration for green methanol processes.

How efficient is hydrogen storage compared to methanol storage?

The round-trip efficiency for hydrogen storage at 38% is higher than for methanol storage with carbon cycling at 35%. Figure 2. Average electricity costs for systems based on wind and solar

How is methanol stored?

Methanol is stored as a liquid at ambient temperature and pressure, oxygen is stored as a liquid at - 183 ∘ C, and carbon dioxide is stored as a liquid at 7 bar and - 50 ∘ C; only hydrogen is stored as a gas (at 250 bar) while it is buffered before going into the methanol synthesis. Figure inspired by Baak et al. 8

Is methanol a cost-effective solution?

Since using the methanol system is still 29%–43% lower in cost than using aboveground pressure vessels for hydrogen, it presents the most cost-effective solution of those studied here where salt deposits are not accessible. The round-trip efficiency for hydrogen storage at 38% is higher than for methanol storage with carbon cycling at 35%.

Can a hybrid hydrogen-battery energy storage system be optimized?

This study proposes a multiobjective optimization for a hybrid hydrogen-battery energy storage system based on hierarchical control and flexible integration for green methanol processes. The optimized energy management strategy aims to comprehensively enhance the economic viability, safety, and resilience of the hybrid system.

How efficient is methanol storage with carbon cycling?

A study on methanol storage with carbon cycling that only considered a static calculation (without time series) found a round-trip efficiency of 30.1% and a LCOS of 240 €/ MWh el. 8 Our round-trip efficiency is higher at 35% because we assume a higher efficiency for the Allam turbine (66% versus 60%) and for the methanol synthesis (83% versus 79%).
