Project summary description:
Existing limitations with the present renewable energy alternating current (AC) microgrids for green hydrogen generation include low efficiency, high cost and size.

This project focusses on the transition from AC to fully DC microgrids for green hydrogen production. Innovation toward direct current (DC) systems is difficult and significantly hampered by the lack of industry experience with dedicated DC microgrids for green hydrogen.

This project uses an efficient, first-of-a-kind fully DC microgrid for green hydrogen production, using electrolysers, solar photovoltaic (PV) generators and battery energy storage systems. In this microgrid, the unnecessary AC/DC and DC/AC power conversions have been eliminated via dedicated DC-DC power converters for electrolyser, PV and battery storage systems.
