.Grid Layouts, Hydrogen 

Water electrolysis requires Direct Current (DC) at low voltage, but renewable electricity for green hydrogen production is typically supplied through an AC grid connection converting AC back to DC. It is therefore of interest to consider more optimised DC-DC connections for large-scale green hydrogen plants.

Therefore, the Institute for Sustainable Process Technology (ISPT), in cooperation with Hitachi Energy and consortium partners Equinor, HyCC, Ørsted, Port of Rotterdam, and Yara International, has completed a feasibility study to explore a (hybrid) electrical layout, incorporating DC and AC connections. The study focuses on developing optimised power conversion schemes for a gigawatt (GW)-scale water electrolysis plant.

The objective is to prepare a conceptual design for a converter topology that enables the integration of this new electrical layout, highlighting both its benefits and limitations.

In this study, a new electrical layout with innovative power converters has been selected due to its relatively high level of maturity, proposed higher efficiency, potentially lowest complexity, costs and footprint.
