Shell, Eneco to build 759MW, subsidy-free hybrid offshore wind project in the Netherlands

Greentech Media:

Oil major Shell and Dutch utility Eneco will build a super-hybrid offshore wind farm, having won the latest Dutch tender.

The pair’s CrossWind consortium was revealed on Wednesday as the winner of the subsidy-free auction for the Hollandse Kust (noord) project. CrossWind plans to have the 759-megawatt offshore wind farm up and running in 2023 with solar, storage and hydrogen elements thrown into the mix. Both companies confirmed that the final investment decision on the project has already been made.

The tender for Hollandse Kust (noord) encouraged participants to incorporate green hydrogen plans. But Shell and Eneco have gone several steps further. In a statement, CrossWind said it would incorporate five technology demonstrations that could be implemented at full scale in the future, combining the various technologies to provide continuous power, regardless of whether the wind is blowing.

The wind farm will be paired with a floating solar facility and a short-duration battery. It will also generate green hydrogen via an electrolyzer that CrossWind says will be used as a “further storage technique.”

Shell said in May that it hopes to use Hollandse Kust (noord) to power a 200-megawatt electrolyzer for one of its own refineries. Other details on the size of the solar and battery components were not immediately available.

The final innovation at Hollandse Kust (noord) will see turbines being “tuned” to ensure that they minimize the wake effects — that is, the impact of one turbine on those behind it, which ultimately reduces power generation. Ørsted last year cut its expected returns on some of its offshore projects because the wake effect had been underestimated in its models.
