No mention here of the huge cost of putting yet more hundreds or thousands of wind turbines miles offshore, or of what is supposed to happen when it’s not windy enough to generate any, or much of, the required electricity – other than vague reference to ‘storage and demand response’, and interconnectivity.
EUROPE: A total offshore wind capacity of at least 230GW is needed in northern Europe by 2045 to meet the requirements of the Paris Agreement, according to newly published research, writes Craig Richard at Windpower Offshore.
This increased capacity in the North Sea, Irish Sea, Channel, Baltic Sea, and Atlantic Ocean would require between 50GW and 80GW of new interconnectivity to ensure reliable operation, energy and climate consultancy Ecofys found.
Of the 230GW total capacity, 180GW would be installed in the North Sea itself, covering approximately 5% of its total area, with the remaining 50GW in other seas, the consultants added.
Beyond 2030 there would be only a “marginal” increase in capacity because “almost all suitable locations for onshore wind will be exploited by then”, Ecofys wrote in its ‘2045 outlook and implications for offshore wind in the North Seas’ report.
The spatial planning required to meet the 2045 target was an “international challenge”, Ecofys noted, and stressed that cross-border collaboration would be needed.
To meet the 230GW target “the offshore wind installation rate needs to increase considerably”, Ecofys wrote.
On average, approximately 3GW a year of offshore wind is expected to be added until 2023, and Ecofys assume an additional increase of 1GW year-on-year between 2023 and 2030.
This approach, with a net installation rate of 10GW a year from 2030 onwards, would be sufficient to reach the 230GW target by 2045.
But the report’s authors warned: “New policies and market integration progress are required to ensure an increased roll-out after 2023 to enable reaching the 2045 target.
“A higher ramp-up could be difficult to achieve due to the required expansion of industrial fabrication and installation capabilities.
“A lower ramp-up, on the other hand, would yield the 2045 target difficult to attain.”
