Hydrogen distribution and transportation

Once produced, hydrogen must be transported and stored for its subsequent use. Given the characteristics of this gas, i.e. flammability, low density, and ease of dispersion in the air, analyses and studies are still underway on the hypothesis of using existing infrastructures or their functional conversion for the passage of hydrogen.

But once the configuration of hydrogen distribution networks is completed, hydrogen will be transported directly to its point of use, avoiding expensive storage in pressurized tanks or even more in liquid form.

Analyses and studies conducted by Kiwa

Studies conducted by Kiwa at Netbeheer Nederland and as part of the Leeds H21 City Gate project by Kiwa UK, show that existing gas networks can be reused to distribute hydrogen, with some adaptations:

• The transition from natural gas to hydrogen will require new gas meters and central heating boilers/hybrid heat pumps specifically designed.
• Installers of gas appliances will need training to install Hydrogen appliances.
• Hydrogen will require odorization so that gas leaks can be easily detected.
• Materials research will be necessary on network components to ensure they are not adversely affected by hydrogen.

The goal is to achieve complete decarbonization by providing new energy solutions to current natural gas users, in the domestic, industrial, and commercial sectors.
