Visser & Smit Bouw works on new substation and Shunt reactor at Tweede Maasvlakte

Contractor Visser & Smit Bouw is working on the engineering and realisation of a new 380kV GIS substation and Shunt reactor at Tweede Maasvlakte near Rotterdam. Both vital for the new high-voltage infrastructure for Shell’s future Holland Hydrogen 1 hydrogen plant where green hydrogen will be produced using wind energy.

Already since early 2021, the company, in collaboration with partner Volker Energy Solutions, has been closely involved in the development of the project by creating the complete basic, final and implementation design.

Green hydrogen with wind energy

The substation will be connected to CrossWind’s Hollandse Kust Noord offshore wind farm. An electrolyser in the hydrogen plant will produce green hydrogen using wind energy. Shell intends to use this hydrogen, among other things, to make the Shell Energy & Chemicals Park Rotterdam (formerly Shell Pernis) more sustainable and, eventually, for heavy transport by road and water.

Due to the high power demand of Holland Hydrogen 1, the substation will be connected directly to TenneT’s 380kV Maasvlakte substation. Visser & Smit commissioning and cooperation partner Volker Energy Solutions is, among other things, realising the approx. 6.5km connection for this. At the time of commissioning of the hydrogen plant in the second half of this decade, this will be the largest electrolyser in Europe with a capacity of 200MW.

The new 380kV GIS substation and Shunt reactor form the backbone of this innovative project and give the plant the necessary clout. Source: Visser & Smit Bouw
