DC | New electrical layout and converters for GW green hydrogen plant

 

 

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.

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.
