Denmark To Trial Green Hydrogen Production Using Offshore Wind Turbines

Danish energy firm Orsted is pushing ahead with plans to develop a demonstration project which will harness offshore wind energy to produce “green” hydrogen.

In an announcement Wednesday, the company said it had taken a final investment decision on the 2 megawatt (MW) H2RES scheme, which will be able to produce up to roughly 1,000 kilograms of renewable hydrogen per day.

Slated to generate its first hydrogen toward the end of this year, the project will be based at Orsted’s Avedøre Power Station, south of Copenhagen.

Orsted said H2RES would assess “how to best combine an electrolyser with the fluctuating power supply from offshore wind.” The power will come from two 3.6 MW turbines, with the hydrogen produced by the system providing fuel for road-based transport.

Hydrogen can be produced in a number of ways. One way includes using electrolysis, with an electric current splitting water into oxygen and hydrogen. If the electricity used in the process comes from a renewable source such as wind then it’s termed “green” or “renewable” hydrogen.
