The federal government has opened up subsidies of NOK 23 billion to the builders of the deliberate bottom-mounted offshore wind farm Sørlige Nordsjø II. In response to DNV calculations, the event of floating offshore wind power on the Utsira area will value taxpayers greater than thrice as a lot this summer time, with an estimated 80 billion in subsidies.
Now know-how entrepreneur Per A. Vatne thinks he has discovered an answer that would be sure that the event of offshore wind can happen with out authorities subsidies.
Cracked the winter code for photo voltaic power: – If you are able to do it, it is an entire new worldA recreation changer?
Vatne has been stimulating know-how improvement within the drilling tools business because the Nineteen Seventies, together with along with Bjarne Skeie. Briefly, he has developed an idea that mixes wave power, hydropower and wind power, the place wave power will elevate water 20 meters as much as a reservoir that encloses the pillar on which the wind turbine stands. From there, the water falls into a standard small energy plant within the column.
– Preliminary analyzes based mostly on wave knowledge within the North Sea point out that wind generators with this know-how can double electrical energy manufacturing, says Vatne.
– Furthermore, the hydroelectric energy station will produce electrical energy even when there isn’t a wind, as there are virtually all the time waves at sea. I feel that is an egg that would turn out to be a recreation changer in offshore wind power improvement, he says.
Along with associate Pål Norheim (66), additionally with over 40 years of expertise within the oil tools business, he based the corporate Stationmar. Right here they’ve introduced in one other business veteran, Morten Steen Martinsen, as chairman.
In response to A. Vatne (left) and Pål Norheim from the corporate Stationmar in Kristiansand have developed an offshore wind turbine that makes use of wave power to pump water, in order that it additionally turns into a small energy plant in the identical space. (Picture: Harald Berglihn)– I feel it’s a very thrilling concept and method to include wave power into an present construction. It issues each prices and revenue, says Arvid Nesse. He heads the floating know-how testing heart exterior Karmøy and can be head of the commerce affiliation Norwegian Offshore Vind.
He says that finally it’s all about lowering prices in kroner per kilowatt hour, and that it’s good that small know-how firms are coming ahead with good concepts.
Harald Dirdal of the corporate Ny Energi, initiator of the wind power consortium Norseman Wind, finds the Stationmar idea very fascinating.
– Particularly as a result of it’s based mostly on well-known know-how. The secret is to make the most of the prevailing construction and probably improve the utilization fee of cables and transformers. That is costly infrastructure that’s sometimes used solely 50 % of the time with conventional offshore wind generators. By combining wave power and wind power, the utilization fee will most likely improve. So it’s clear that that is very fascinating, particularly for a improvement as far offshore as Sørlige Nordsjø II, he says.
Race
It would probably value a minimum of NOK 100 million to construct a full facility to check whether or not the know-how works at sea. Neither Vatne nor Norheim have any cash after Stationmar has spent round NOK 25 million thus far, primarily on the know-how that neutralizes wave actions in floating offshore wind generators.
The small know-how firm in Kristiansand is actually not alone in creating new concepts for offshore wind power.
The article continues under the commercial– Lately, greater than 200 offshore wind tasks have acquired assist from us, says Eli Wærum Rognerud, head of strategic initiatives at Innovation Norway.
– We gave a minimum of NOK 80 million in 2022 to finance offshore wind tasks. The Analysis Council additionally gave NOK 80 million and Enova 32 million, she says, including that Innovation Norway additionally spent NOK 26 million final yr on export companies associated to offshore wind power, reminiscent of worldwide festivals, delegations, export packages, market consultancy and advertising.
– Generally, we’re experiencing a robust improve within the variety of questions on offshore wind power, each about financing and, final however not least, about recommendation, says Wærum Rognerud.
Oskar Gärdeman is a senior advisor at Enova, the state-owned firm tasked with contributing to the transformation of power consumption and manufacturing. He factors out that Enova is in fixed competitors with a funds of NOK two billion, centered on new know-how and options for fluid manufacturing.
– In essence, it’s about making certain that Norway will get off to a quick begin, and that the price of floating offshore wind power is decreased, which on the similar time can provide us a bonus over different international locations. So there’s a lot taking place right here at many Petter Smarters with new options, however what we’re primarily searching for are strong options that may cut back prices, says Gärdeman.
– Like Stationmar’s idea with the mixture of wind and water energy?
– There may be all the time the hazard that tasks involving a number of applied sciences additionally entail too excessive a technological threat. It’s a harsh surroundings at sea. However I do not rule something out.
– What we see is that the price of floating offshore wind power must be decreased to a complete value over the lifetime of the plant of 50-60 øre per kilowatt hour. At the moment we’re nonetheless a great distance from that, he says.
DNV has beforehand estimated prices in Utsira Nord at round NOK 1.50 per kilowatt hour, and that relying on the electrical energy value, there may be more likely to be a necessity for a minimum of thrice increased subsidies than the NOK 23 billion that the federal government has set as a situation. framework for the Southern North Sea mission.
– If we wish to cut back the 50-60 øre, we want to have the ability to cut back prices in all areas – every little thing from generators, towers, floats, anchoring and cabling, marine operations and upkeep. By means of the assist packages, our process is to make sure that floating offshore wind farms may be developed on business phrases, with out the necessity for presidency subsidies, says Gärdeman in Enova.
