The transmission system operator TenneT right now offered a technological innovation that may considerably speed up offshore grid growth for wind energy within the North Sea. With the wind energy booster, six gigawatts of offshore capability will be realised three years earlier. For comparability: six gigawatts of capability correspond to 6 massive energy crops.
The idea was offered in Germany along with the Power Ministers of Decrease Saxony, Olaf Lies, and Schleswig-Holstein, Jan Philipp Albrecht, in addition to Bremen’s State Councillor Kai Stührenberg – representing Bremen’s Senator for Financial Affairs Kristina Vogt.
The wind energy booster is a primary concrete step in the direction of a long-term meshed excessive voltage direct present grid at sea and on land. A meshed direct present grid (HVDC overlay grid) on land and at sea ensures long-term safety of provide and reduces the financial prices of integrating renewable energies to attain the local weather targets.
Essential corporations, together with e.g. ArcelorMittal, Entwicklungsagentur Area Heide, EWE, Holcim, Hynamics, Ørsted, Raffinerie Heide, Salzgitter AG, Uniper and the wind vitality associations BWO and WAB assist TenneT’s initiative.
TenneT COO Tim Meyerjürgens stated: “Constructing on our intensive expertise within the development and operation of offshore grid connections, our conceptual and technological innovation for a six-gigawatt hub demonstrates a option to considerably speed up the achievement of formidable local weather safety targets. We see this as a suggestion additionally for the German authorities coalition negotiations presently underway, which, as we all know, are looking for a lift for the growth of renewable energies in Germany. On the identical time, we’re laying the inspiration for a sustainable interconnection of the direct present grid. On this manner, we’re sustainably growing effectivity in addition to safety of provide and making an vital contribution to the clever coupling of offshore wind with electrolysers to be constructed near era and the fuel grid.”
Olaf Lies, Decrease Saxony’s Minister of Power and the Setting, stated: “The important thing function of offshore wind vitality for the vitality and local weather objectives turns into even clearer once we have a look at the cross-sectoral implementation of the vitality transition – i.e. additionally the vitality must be met by renewables exterior the electrical energy sector. This won’t be attainable with out inexperienced hydrogen and the inexperienced electrical energy it requires. Along with the function in vitality and local weather coverage, there may be additionally the significance when it comes to industrial and employment coverage – for northern Germany, but in addition far past. Along with our neighbouring federal states, Decrease Saxony has the prospect to develop into the gateway for offshore vitality for the entire of Germany. So as to have the ability to decisively use the alternatives of hydrogen expertise within the sense of a sustainable vitality provide for the native business and enterprise location, we should already create the technical conditions right now and subsequently additionally provoke a big step in grid planning within the course of a future-oriented, cost-efficient and internationally related direct present grid. In view of the latest stagnation within the growth of offshore wind vitality, we additionally want approaches like this that permit us to select up the tempo once more. As a result of time is in any other case working out. Making ready for the longer term multi-terminal deployment would even have direct advantages in Wilhelmshaven by requiring much less area for the deliberate initiatives on website.”
“The idea offered to speed up the growth of offshore wind vitality use whereas saving energy strains is a constructing block in the best course. We have to provide you with a viable goal idea as quickly as attainable on how we wish to broaden our infrastructure by 2045,” stated Schleswig-Holstein’s Minister of Power Jan Philipp Albrecht. “And we now have to begin planning for this right now. We would like a European vitality transition and this features a European system interconnection that features not solely electrical energy but in addition the manufacturing and transport of inexperienced hydrogen. We’ll take an integrative, interconnected method and construct robust future-proof vitality infrastructures within the centre of Europe.”
Kristina Vogt, Bremen’s Senator for Financial Affairs, Labour and Europe, stated: “The dedication to renewable energies and particularly the elevated growth of offshore wind vitality to attain local weather targets has lengthy been one in every of my core considerations. The idea offered to speed up the growth of offshore wind vitality is a superb instance of how this growth will be achieved extra rapidly with artistic concepts. As an industrial location with a considerably increased electrical energy demand sooner or later, the state of Bremen will profit instantly from this. Greenhouse fuel emissions will be diminished and worth creation and jobs secured on the identical time.”
The idea at a look
With the wind energy booster idea, TenneT is proposing very particular measures that may make it attainable to combine six gigawatts of offshore wind energy into the ability grid as early as 2032, as a substitute of 2035, i.e. three years ahead of beforehand envisaged within the grid growth plan, in a primary step. The idea consists of the next constructing blocks:
Benefit: Acceleration of offshore growth
TenneT is accountable for the development of round 17 of the presently deliberate 20 gigawatts of offshore transmission capability within the North Sea and Baltic Sea by 2030. With the proposed growth path for an additional six gigawatts by 2032, which was beforehand not deliberate till 2035, Germany’s offshore growth targets will be considerably elevated within the brief time period and thus contribute to accelerated implementation on the trail to local weather neutrality.
Benefit: Worldwide connections within the North Sea
With a view to obtain the European local weather targets, the growth of offshore wind vitality within the North Sea have to be deliberate throughout nationwide borders in the long run. What is required is a North Sea offshore grid that connects the riparian states. That is notably vital for Germany, because the German offshore wind potential won’t be adequate to attain the German local weather targets by 2045. The interconnection of a number of offshore connections from completely different states will increase effectivity, safety of provide and creates new European electrical energy buying and selling capacities. The modular idea of the LanWin hub allows, for instance, interconnection with the Danish “vitality island” and, sooner or later, with different North Sea international locations. This distribution hub could be established within the LanWin space of the German International Financial Zone within the North Sea, round 150 kilometres off the German coast.
Benefit: Sensible sector coupling on the coastal grid interconnection factors
Till now, offshore wind farms have all the time been related to the onshore electrical energy grid by point-to-point connections. With a view to obtain Germany’s and Europe’s formidable local weather targets, it’s needed to determine an internationally meshed direct present grid at sea and on land as a way to transport extra vitality by the deliberate direct present strains on land. On the offshore grid interconnection factors close to the coast, along with decarbonising energy-intensive processes, clever sector coupling with deliberate electrolysis initiatives in addition to with the fuel infrastructure and the feed-in of onshore wind vitality is deliberate.
Benefit: Much less land consumption on land
With a view to provide personal shoppers, business and deliberate electrolysis initiatives with offshore wind vitality, in addition to to allow a direct reference to persevering with direct present strains on land, the three offshore connections will land near the coast in Heide (Schleswig-Holstein), Wilhelmshaven (Decrease Saxony) and within the Bremen space. The wind energy booster idea offers aid for the necessity for area and land within the coastal areas and on the identical time gives new alternatives for the commercial clusters situated there. Every of those three areas is to be built-in as a wind energy booster with a two-gigawatt connection.
Benefit: expertise and innovation
TenneT has already realised 14 offshore grid connections within the Netherlands and Germany and thus operates greater than half of the offshore grid connection capability within the EU. TenneT makes use of the know-how it has developed on this option to the benefit of latest initiatives. For the LanWin hub, TenneT is counting on its progressive two-gigawatt commonplace for direct present connections, supplemented by additional technological developments for the wind energy booster idea. The brand new commonplace goals to additional cut back the prices of offshore grid growth and minimise spatial and environmental impacts.
Supporters of the TenneT initiative
Quite a few corporations from business and the vitality sector in addition to business associations assist TenneT’s initiative to speed up the realisation of offshore growth targets within the North Sea. TenneT is utilizing the wind energy booster idea: the development of modular wind energy hubs at sea and on land is mixed with grid-serving places which might be appropriate for business. The intention is to hyperlink options for decarbonising energy-intensive processes in business and for the good coupling of wind vitality with hydrogen with the creation of a world community of direct present strains. As well as, the direct interconnection of a number of offshore connections from completely different international locations will increase effectivity, safety of provide and creates new European electrical energy buying and selling capacities.
