DNV GL found that estimated hydrogen supply in the Netherlands is 59% higher than previously estimated, adjusting it from 110 PJ per year in 2017 to 175 PJ in 2019 (Figure 1). This is based on the hydrogen production capacity in the five main industrial clusters considered: Eemshaven, IJmond, Maasdelta, Zeeuws-Vlaanderen and Limburg.
The difference in the data between 2017 and 2019 relates to a previously unaccounted-for increase in hydrogen supply capacity, as well as lower base assumptions in the original data set. The majority share (71%) of this increase relates to continued investment in the petrochemical sector (and the associated endogenous hydrogen production) in the Maasdelta cluster. The other share (23%) was due to supply assumptions at fertilizer producers that proved to be too low based on output reported.
