"If the hydrogen is sourced from an electrolysis unit, the power consumption (for hydrogen generation only) will be approximately 10.5 MWh per ton methanol."
That does seem like a lot of energy to create very little fuel, which is going to be released again as CO2 anyway.
- guerby 5y agoAccording to: https://en.wikipedia.org/wiki/Methanol_fuel https://en.wikipedia.org/wiki/Methanol_fuel Methanol is 19.7 MJ/kg so 5.47 kWh/kg and 5.47 MWh per ton. I assume shipping is not often weight constrained. https://en.wikipedia.org/wiki/Heavy_fuel_oil https://en.wikipedia.org/wiki/Heavy_fuel_oil https://transportgeography.org/contents/chapter4/transportation-and-energy/combustibles-energy-content/ https://transportgeography.org/contents/chapter4/transportat... Current "bunker oil" is 40 MJ/kg so approximately double, but toxic emissions (sulfur content) are so bad that some countries/states mandate using a less polluting (less sulfur) fuel when near coasts.
