“…"Replanting" (discussed in [8]) and "end-of-life extensions" (Table 3) did not find resonance in the offshore wind literature. There were 280 publications on wind and repowering on Scopus with the potential to transfer expertise from onshore to offshore wind, as the repowering of onshore wind farms is already more widespread (see, e.g., [207][208][209][210][211][212][213][214][215][216]).…”

Circular economy and renewable energy infrastructure such as offshore wind farms are often assumed to be developed in synergy as part of sustainable transitions. Offshore wind is among the preferred technologies for low-carbon energy. Deployment is forecast to accelerate over ten times faster than onshore wind between 2021 and 2025, while the first generation of offshore wind turbines is about to be decommissioned. However, the growing scale of offshore wind brings new sustainability challenges. Many of the challenges are circular economy-related, such as increasing resource exploitation and competition and underdeveloped end-of-use solutions for decommissioned components and materials. However, circular economy is not yet commonly and systematically applied to offshore wind. Circular economy is a whole system approach aiming to make better use of products, components and materials throughout their consecutive lifecycles. The purpose of this study is to enable the integration of a sustainable circular economy into the design, development, operation and end-of-use management of offshore wind infrastructure. This will require a holistic overview of potential circular economy strategies that apply to offshore wind, because focus on no, or a subset of, circular solutions would open the sector to the risk of unintended consequences, such as replacing carbon impacts with water pollution, and short-term private cost savings with long-term bills for taxpayers. This study starts with a systematic review of circular economy and wind literature as a basis for the coproduction of a framework to embed a sustainable circular economy throughout the lifecycle of offshore wind energy infrastructure, resulting in eighteen strategies: design for circular economy, data and information, recertification, dematerialisation, waste prevention, modularisation, maintenance and repair, reuse and repurpose, refurbish and remanufacturing, lifetime extension, repowering, decommissioning, site recovery, disassembly, recycling, energy recovery, landfill and re-mining. An initial baseline review for each strategy is included. The application and transferability of the framework to other energy sectors, such as oil and gas and onshore wind, are discussed. This article concludes with an agenda for research and innovation and actions to take by industry and government.

“…Repowering significa sostituire i vecchi modelli di turbine eoliche con quelli nuovi. Ci sono diversi vantaggi poiché la prima generazione di turbine eoliche può essere sostituita con moderne turbine eoliche multi-megawatt, e nei paesi che hanno iniziato presto con l'energia eolica, di solito le vecchie turbine eoliche sono collocate in luoghi in cui le condizioni di vento sono ottimali, e quindi le moderne turbine eoliche avranno prestazioni migliori, con un aumento della produzione energetica, minori impatti ambientali e un migliore sfruttamento delle risorse 19,20 . I fattori economici e il complesso processo di autorizzazione sono i principali ostacoli.…”

L’energia eolica negli ultimi anni ha avuto un forte incremento e la dismissione degli impianti eolici già esistenti sta suscitando molto interesse sul possibile recupero delle risorse. Una turbina eolica ha una durata media di vita tra 20-25 anni, e oggi 34,000 turbine in Europa hanno 15 anni o più. Una stima di 14,000 pale potrebbe essere disattivata entro il 2023, un equivalente tra 40,000 e 60,000 tonnellate. Pertanto, un mercato potenziale per le turbine eoliche fuori uso e i loro prodotti recuperati deve essere stabilito in Europa. Circa l’85-90% della massa totale delle turbine eoliche può essere riciclata. Il problema principale rimane sulle pale, che sono realizzate in materiale polimerico rinforzato con fibre, i cui metodi di riciclaggio non sono tecnologicamente sviluppati. La situazione di fine vita di un parco eolico richiede una decisione tra differenti possibili progetti sostenibili per l’medio ambiente. La decisione finale sarà influenzata da diversi fattori.

“…In 2021, two studies analyzed the technical-economic factors, Ceolin de Bona in Brazil [70] and Al Hamed with a case study in Denmark [72]. In the case of Brazil, 2 MW is the nominal power limit per wind turbine to change to others of higher rated power, unless they are replaced by taller towers.…”

The integration of renewables into power systems is a key transformation for mitigating climate change and reducing fossil-fuel dependence. Among the different resources, wind participation has become crucial in recent decades—both onshore and offshore wind power plants. However, assuming the useful life of the wind turbines at approximately 20 years, different solutions should be discussed to overcome the turbine’s aging problem. In the coming years, some countries within the wind sector will face the decision of partially or totally repowering or dismantling their turbines. This paper reviews different repowering strategies and contributions from a multifactorial perspective. A set of categories is defined by the authors and those multifactorial parameters are then classified according to such categories: technical, economic, environmental, social, and political. From each category, the most relevant factors to be considered for repowering decision-making purposes are identified and discussed. According to the specific literature, more than 90% of the reviewed contributions are focused on onshore wind power plant repowering actions. This percentage is in line with onshore and offshore wind generation units installed in recent decades. The reviewed studies show that Germany has a major number of contributions. Regarding offshore repowering strategies, all contributions propose a multifactorial analysis, in contrast to onshore repowering strategies where only 68% of the authors carry out a multifactorial analysis. The revised repowering methodologies and the categorization of factors can also be used by the repowering market, as a useful tool in the near future.
