The scenario (2) corresponds to the situation where only the curtailed renewable electricity is used to produce hydrogen. To conduct this scenario, the author
uses the curtailment ratio obtained from the relevant literature.
The scenario (3) establishes that in a liberalised energy market highly penetrated by renewables, the production of renewable hydrogen by water electrolysis is
profitable 2550 hours a year (van Leeuwen and Mulder 2018).
5.3.2 Determining the Hydrogen Demand
The research work focuses on the hydrogen demand for carbon intensive industry
sectors such as the petrochemical feedstock production, the oil refining, and the
steel manufacturing.
The hydrogen demand assessment is based on the production data of the case
studies. The production of ammonia [Table 5.6] and methanol [Table 5.7] data are
used for the petrochemical feedstock production.
