Hydrogen Distribution and Transport Networks

Once produced, hydrogen must be transported and stored for subsequent use and the applications for which it was generated. Given the characteristics of this gas—flammability, low density, and ease of dispersion in the air—analyses and studies are still ongoing regarding the potential use of existing infrastructures or their conversion to be suitable for the passage of H2.

However, once the configuration of hydrogen distribution networks is complete, hydrogen can be transported directly to its point of use, avoiding the costly storage in pressurized tanks or, even more so, in liquid form.

Analyses and studies conducted by Kiwa at Netbeheer Nederland and within the Leeds H21 City Gate project by Kiwa UK show that existing gas networks can be repurposed to distribute hydrogen, with some adjustments:

The transition from natural gas to hydrogen will require new gas meters and boilers for central heating/hybrid heat pumps designed for hydrogen.
Gas appliance installers will need training to install hydrogen appliances.
Hydrogen will require odorization so that gas leaks can be easily detected.
Research on materials will be necessary for the network components to ensure they are not negatively affected by hydrogen.

In this case, the goal is to achieve full decarbonization, providing new energy solutions to current natural gas users in the domestic, industrial, and commercial sectors.
