The shallowest area of the North Sea is the ‘Dogger Bank’, a sandbank with size of 17.600 m2, located 100 km east of the English coast of Yorkshire and ca.150 km west of the Danish cost. The water depth ranges from 15–36 metres, about 20 metres shallower than the surrounding sea. Dogger Bank also adjoins the borders of Britain, the Netherlands, Germany and Denmark, therefore has the potential of becoming a European wind park. Energy storage could take place in the form of a ring-shaped dyke around the wind park. By pumping water up to this new polder, the differences in height could be used to additionally generate energy. Further, this polder, or atoll, could be used simultaneously as space for holiday homes, a national airport, an accompanying city or a central European container harbor. However, due to its distance to the mainland, the construction of long pipelines would result in high costs.
Alternatively, the wind park could be constructed closer to the coast which would reduce the length of the pipelines and make the airport option more realistic. A 20-25km distance to the coast would need to be kept in order to keep the windmills out of sight. The sea is 100m deep there. Because of territorial land claims, a splintered band of windmills would appear. A windmill archipelago with a band width of 45m.
