Which is better methane energy storage or methanol energy storage

Is energy storage more efficient in methanol than methane?

In ideal conditions, where no additional energy is required for the reaction and CO 2 is fully converted into products, energy storage is 8% more efficient in methanol than methane. However, the Sabatier reaction can be performed with a lower degree of complexity compared to the CO 2 to methanol reaction.

What is the energy storage potential of methanol and methane?

Energy storage potential of the two carries is compared and optimized. Maximal storage efficiency is 85.3% for methanol and 78.2% for methane. Methanol production from CO 2 is optimized in an energy storage perspective. The optimal energy storage system is designed as a combination of the two reactions.

Are methane and methanol storage characteristics similar?

Storage characteristics of methane and methanol are compared here, based on the same basic data and for the same storage capacity; both measures of energy content are in TWhel. A key question is the selection of the storage capacity. However, substantial differences were found in literature reports (Table 8.9).

Can methanol production from CO2 be optimized in energy storage?

Methanol production from CO 2 is optimized in an energy storage perspective. The optimal energy storage system is designed as a combination of the two reactions. This study analyses the power to methane - and to methanol processes in the view of their efficiency in energy storage.

What is the difference between methanol and methane?

In ideal conditions (no energy losses), the methanol process stores 85.3% of the hydrogen energy, while methane stores only 78.2% of the energy. However, the production of methanol from CO 2 suffers from various drawbacks and technological problems that are not present in the CO 2 to methane process.

What are methane and methanol used for?

Both methane and methanol are valuable compounds in the energy sector and base materials for the chemical industry. The main application in the energy sector is their use as fuel and as energy carrier for RE storage. 8.4.1 Fuel
