“…A broader Scopus search for literature on the interface of the subjects of "circular economy" and "wind" (3 June 2021) returned 91 publications, of which 39 hold direct importance and 27 are peripherally relevant-66 in total (Figure 1). About a third of the 66 titles broadly discuss: the role of wind and other renewable energy technologies to power a sustainable and circular economy [57,58,[67][68][69][70][71][72][73][74][75][76][77], or battery storage (e.g., [72,78]) and the potential for integration with a hydrogen economy to avoid a loss of generated wind power (e.g., [79]), using hydrogen subsequently in methanol production [80][81][82]. Schoden et al [83] present a project to raise public awareness about the need for a circular economy for wind turbines.…”

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.

“…In the case of excess wind and solar energy, it is important to understand how to use them to produce hydrogen and promote sustainable energy development (Nadaleti et al, 2020). The energy storage system and the transmission network are combined to avoid the imbalance in the performance of RERs power generation, and the excess RERs can be transmitted to the power market for digestion (Zhang et al, 2020).…”

Planning for the research and development (R&D) of renewable energy resources (RERs) has not received enough attention. This paper aims to study the planning for the R&D of RERs in order to avoid bottlenecks and ensure sustainable development in developing marine economies. We have established a triple difference model (DDD) model and a wise pig game model between the theoretical government and enterprise. The data on RERs come from the World Bank and International Energy Agency databases. We have three contributions on the basis of distinguishing between mature and immature marine RERs technologies. First, it emphasizes the importance of developing R&D planning for marine RERs immature technology in the future. Second, the DDD model is used to empirically establish whether RERs planning has a significant positive impact on RERs’ output, which explains the importance of existing RERs planning. Third, the wise pig game model is used to analyze the welfare benefits to the government brought by the R&D planning of marine RERs which proves the importance of future RERs R&D planning.

“…Although renewable energies such as solar, wind, and tidal energies may produce net-zero carbon emissions, their effectiveness is intermittent and consequently cannot be used as dispatchable energy sources. Accordingly, the widespread use of such energies will require the development of energy carries also without significant carbon production, such as batteries, compressed air, hydrogen (H 2 ) etc (Cherigui et al, 2008;Mah et al, 2019;Nadaleti et al, 2020). Among these energy carries, H 2 is typically viewed as the most promising energy carrier due to its superior features, such as high energy density and low energy loss during its storage process.…”

“…The development of H 2 end-use products and the construction has become pivotal factors for improving the competitiveness and sustainable development of an H 2 industry (Chintala and Subramanian, 2017). A sketch of the process from H 2 production to its comprehensive application as an energy source is shown in Figure 1 (Nadaleti et al, 2020). Currently, among various H 2 applications, H 2 fuel cell (HFC) technology represents the highest energy efficiency.…”

Analysis of Hydrogen Gas Injection at Various Compositions in an Existing Natural Gas Pipeline

The lack of hydrogen (H2) transportation infrastructure restricts the development of the H2 industry. Owing to the high investment of building specific facilities, using existing natural gas (NG) pipelines to transport a blend of H2 and NG (H2NG) is a viable means of transportation and approach for large-scale long-time storage. However, variation in the thermo-physical properties of an H2NG blend will impact the performance of pipeline appliances. To address the gaps in H2 transmission via an NG system in the context of energy consumption, in the present paper, a one-dimensional pipeline model is proposed to predict the blended flow in a real existing pipeline (Shan–Jing I, China). The data of NG components were derived from real gas fields. Furthermore, the influence of H2 fractions on pipeline energy coefficient and the layout of pressurization stations are comprehensively analyzed. In addition, the case of intermediate gas injection is investigated, and the effects of injection positions are studied. This study serves as a useful reference for the design of an H2NG pipeline system. The present study reveals that with the increasing in H2 fraction, the distance between pressure stations increases. Furthermore, when the arrangement of original pressure stations is maintained, overpressure occur. Intermediate gas injection results in the inlet pressure of subsequent pressurization stations reducing. Using existing pipeline network to transport H2NG, it is necessary to make appropriate adjustment.
