Green hydrogen to decarbonise heavy industry & transport

Energy Solutions

H2RES is a project led by Ørsted, with funding from the Energy Technology Development and Demonstration Program (EUDP), to investigate the best means of combining an offshore wind power supply with an efficient electrolyser. The project’s demonstration plant will have a capacity of 2 MW, and use Ørsted’s two 3.6 MW offshore wind turbines at Avedøre Holme to create green hydrogen fuel via electrolysis.

The facility is expected to produce around 1,000 kg of renewable hydrogen a day from late 2021, which can be converted into green fuels and will help to achieve zero-emission road transport in Greater Copenhagen & Zealand. Ørsted aims to facilitate decarbonisation for sectors that can’t use renewable power directly such as heavy industry and transport.

H2RES is an important step for Ørsted’s renewable hydrogen ambitions, and the transition of the European economy to net-zero emissions by 2050. COWI is the sole consultant and advisor for the project, and has developed the concept and project description, a detailed design for the demonstration plant, and assisted with the budget and the design of tender documents.

Alongside Ørsted, the project partners are Everfuel Europe A/S, NEL Hydrogen A/S, GreenHydrogen A/S, DSV Panalpina A/S, Hydrogen Denmark and Energinet Elsystemansvar A/S.
