Hydrogen to methanol
CO2 variety of sources for the methanol reaction
-
Criteria for assessment of the different sources àenvironmental impact and energy consumption
-
Preferred source à CO2 contained in biogas (ca. 40%). In the processing of biogas for feeding into the gas grid, this separation is carried out
-
CO2 from fossil fuel power plants and industrial installations à not carbon neutral (CO2 re-enters in energetic utilization of methanol in the atmosphere). However, major potential
-
CO2 separation from the air à rarely used today (technical and economic constrains)
Advantages of conversion of hydrogen in methanol
- Methanol is easier to store, transport and distribute. The storage infrastructure in the oil industry can be used (minor modifications to tanks and pipelines necessaryà brittle plastics and rubber seals)
- Methanol has significantly higher volumetric energy density under standard conditions (H2 (g); CH3OH (l))
- Methanol has a variety of uses
