An ambitious project initiated by Cadent, the main UK network provider, plans to provide first the industrial sector in Liverpool and Manchester with the cleaner hydrogen and later private households. For the pilot study, which is aimed to start in the 2020s, an investment of £600M is planned.

However, some critical issues must be raised and overcome to make the switch from methane gas to hydrogen possible: In the study, households will receive a blend of methane with up to a fifth of hydrogen, thus avoiding the expensive change of boilers to hydrogen-compatible ones (26M in the test area alone). Furthermore, to encounter fluctuation in gas consumption, particularly from private homes, hydrogen storage needs to be created.

The carbon savings will be made from the way the hydrogen is produced:
