Questions about H₂

  • Why hydrogen?

Hydrogen is set to be the fuel of the future. Hydrogen offers many advantages: abundant in earth, does not pollute or produce harmful residues, can be obtained from various sources, can be stored in different ways, can be transported in large scale, can be transformated into electricity without burning and becomes the base to produce other fuels. 

Questions about Methanol

  • Why methanol?

Methanol is the simplest alcohol molecule and is expected to play a leading role in the transition to the not-so-far in the future Hydrogen Economy. ​​An efficient hydrogen carrier will be needed while extensive hydrogen pipelines do not become common place in the new society. 

Main Methanol highlights: high density hydrogen carrier (CH₃OH), liquid at room temperature & safe to transport, low carbon fuel helpful for the energy transition, widely available thanks to its usage in maritime & industry sectors, global capacity expected to double before 2030, able to deliver H₂ at affordable costs, can be manufactured in ecofriendly mode (green), if green, all applications are carbon neutral. 

  • Methanol: The solution to the H₂ logistics

From 1 to 12 efficiency ratio*​. 

Compressed Hydrogen logistic riddle solved by Methanol 

  • The main problem of compressed Hydrogen relies in its logistics. 

  • One 30 ton compressed gas truck can only carry 400 kgs of H₂ ​

  • One 30 ton methanol truck can carry 12 times more.

For long distance transportation methanol beats compressed H₂​

*  250 bars pressure 

  • Toxicity of different fuels to the environment

It is measured by the amount of fuel diluted in a portion of seawater that kills half of its marine life.

Methanol 15400 mg/lt; Fuel Oil 79 mg/lt, Diesel 65 mg/lt; Methane 49,9 mg/lt; Ammonia 9,8 mg/lt; Gasoline 8,2 mg/lt. 

Methanol is by far the most environmental friendly fuel.

  • Disadvantages of ammonia as a hydrogen carrier

Ammonia exhibits several drawbacks when compared to methanol for hydrogen production. These include its inherent toxicity and corrosive nature, the relatively limited availability of infrastructure for its storage and distribution, higher initial investment costs associated with specialized handling equipment, lower energy efficiency due to the thermal decomposition process required for ammonia conversion, and potential carbon emissions during its production. While methanol also presents certain disadvantages, it is generally regarded as a more practical choice in terms of handling, existing infrastructure, and overall energy efficiency.

  • Production of e-Methanol from green hydrogen production (CCUS) 

The process steps of manufacturing e-Methanol through carbon capture technologies (CCUS), are the following,

  1. Electric generation from renewable sources

  2. With green electricity, the electrolyzer produces green H₂ from water

  3. Captured Co₂ (various sources) is supplied 

  4. e-Methanol synthesis (H₂ + CO₂ + water vapour) 

  5. Storage tanks 

  6. Methanol ready for multiple applications
