Speaking of shell's...

The subsidiaries of Shell plc SHEL have taken the final investment decision to construct a major hydrogen plant in the Netherlands — Holland Hydrogen I — which, per the oil supermajor, will be the largest in Europe once it commences operations in 2025.

Per Shell, the 200-megawatt electrolyzer will be built on the Tweede Maasvlakte situated in the port of Rotterdam and will have an output of up to 60,000 kilograms of renewable hydrogen per day. Partly owned by SHEL, the offshore wind farm — Hollandse Kust Noord — will be the source of renewable power for the electrolyzer.
