The North Sea is spatially dominated by either offshore economic activities or reserved areas. A large variety of offshore activities have their claim on the North Sea domain, like fishery, offshore wind energy and offshore hydrocarbon production. Large shipping routes cross through the area and there is always a delicate balance with reserved areas for environmental protection or safety (defence area). The North Sea Energy atlas provides an international overview of a range of important activities at the North Sea in the field of energy, transport, ecology, fishery and defense. It shows the current energy flows from oil and gas production and wind energy, and visualizes new perspectives on the potential future development of our offshore energy system, including the planned expansion of wind energy production, the potential for electrification of platforms, infrastructure for hydrogen and CO2 storage, and combinations of synergetic activities in energy hubs at the North Sea.
