To guage by the packed convention halls at floating wind business occasions this yr in Houston, Tokyo, Aberdeen and even Portland, Maine, you’d suppose the sector was in good well being, heading quick towards beforehand predicted multi-gigawatt forecasts from numerous events – with many nonetheless suggesting as a lot as 10-16GW could possibly be constructed and turning by the top of this decade.
The prospects are actually now very completely different, extra probably 1-2GW, with the most important share being in China.
Regardless of the sector having expanded from a single turbine off Norway in 2009 to some 250MW now in operation world wide, floating wind’s 350GW undertaking pipeline continues to be simply very a lot that, a ‘pipeline’, and, from Aegir’s numbers, the sector is unlikely to have a single commercial-scale (that’s, 300MW-plus) undertaking in operation by 2030 – besides maybe off China.
Ponderous website allowing processes and a scarcity of readability on help mechanisms have an ideal deal to reply for, after all, in slowing the tempo of floating wind’s cost-reduction efforts. The traditional bottom-fixed sector’s story of cost-out within the final decade got here from quite a few North Sea nations offering substantial subsidy schemes which allowed provide chains to take form round regular, long-visibility supply orderbooks. This was a dangerous guess with offshore wind then sitting above €150/MWh ($158/MWh) however one which paid off with that determine falling 70% over a decade.
At this time, it’s onerous to see any authorities making that sort of wager on floating wind to attain such velocity and certainty of cost-out. That may require gigawatt-scale help, somewhat than megawatt-scale as is presently the case.
To make sure, the previous yr has been banner for floating wind. In Europe, Scotland’s 28GW ScotWind awards was 75% in water depths needing floating expertise; Norway moved ever-closer to a deepwater public sale – whereas putting in the world’s largest floating array, the 95MW Hywind Tampen; Portugal and Spain each pledged floating wind tenders; and France began crusing out flagship pre-commercial initiatives forward of a floating-specific public sale.

Throughout within the US Pacific, California handed out leases for some 6GW+ of floating developments, and superior deepwater auctions off Oregon and within the Gulf of Maine. And in Asia, first business initiatives are pushing forward with allowing, with some line-of-sight on last funding choices.
However extra tellingly, many Northern European international locations, together with Denmark, Germany, and the Netherlands, are considerably increasing fixed-bottom lease rounds, which can with out query be far cheaper acreage than what will be present in potential floating wind areas across the North Sea. And within the US, scoping work for upcoming leasing within the Central Atlantic and Gulf of Mexico by federal authorities has quietly been shifted nearer to shore, shelving deepwater areas in the intervening time.
Monopiles mount a problem
Floating wind faces one other problem too: the XX(X)L monopile. Not way back it was debated whether or not bottom-fixed initiatives could be confined to water depths of beneath 40 metres, with 40-60 metres the protect of jacket foundations, and something deeper the area of floating platforms. However monopiles have continued to develop past earlier expectations, and ideas at the moment are being designed to be piled-in in water depths as nice as 60 metres, after which jackets may go deeper, reducing into the marketplace for ‘shallow water’ floating.
The concern not often shared publicly in floating wind circles is that these market crosswinds may result in small-scale, fragmented deployment of lead-off initiatives throughout three continents. This isn’t a recipe for profitable cost-out.
Floating wind, from our view at Aegir, nonetheless has a shiny business future – simply not by 2030. However to make sure this actuality does ultimately materialise, authorities and business must shake itself out of the delusion – not least at sector conferences – that floating wind is on something just like the trajectory of the once-claimed 10-16GW operational by 2030.
The longer this unrealistic view of floating wind’s near-term future persists, the longer we’re ignoring the main interventions wanted to get the sector on a business observe.
