They proposed combining solar methanol islands and human-made marine structures that use renewable energy to harvest CO 2 from seawater and catalysis to produce methanol. This approach uses clusters of marine-based
6 FAQs about [Methanol energy storage method]
Can methanol be used as an energy storage medium?
As an energy storage medium, methanol displays high performance as an additive or substitute for gasoline in internal combustion engines. The direct conversion of the chemical energy in methanol to electrical power at ambient temperature has been demonstrated in methanol fuel cells (McGrath et al., 2004).
Why is methanol a good energy carrier?
The identified strengths of methanol as an energy carrier include its high volumetric energy density, the mature technology for producing it from hydrogen and carbon dioxide, and its broad applicability.
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
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
Does methanol storage reduce the cost of electricity?
The annualized cost of methanol was minimized for a grid-connected and a stand-alone case study considering current and future (2030) unit cost scenarios. The optimization results confirm that storage, especially hydrogen storage, is particularly beneficial when the electricity price is high and highly fluctuating.
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%).
