possible to estimate how much the renewable electricity generation of the study
cases can fulfil the renewable hydrogen demand. The order of magnitude for
decarbonisation potential for a given study case is obtained from the following
formula:
Decarbonisation potential =
Available R E Generation
Required R E Generation f or H 2R E pr oduction
(6)
Where:
• The decarbonisation potential is expressed in percentage.
