O objetivo deste estudo é apresentar os benefícios e impactos advindos da implantação de empresas de geração de energia eólica em comunidades do Rio Grande do Norte, Brasil. O estudo se apoia na teoria dos stakeholders. Para isso, foram feitas visitas técnicas em dois parques eólicos de uma empresa multinacional produtora e em cinco comunidades impactadas pela influência destes. Foram aplicadas entrevistas na empresa e nas comunidades vizinhas, que sofrem impactos diretos dos aerogeradores. Outro instrumento de coleta de dados foi o relatório de auditoria independente e os relatórios socioambientais da corporação. Os resultados apontam para aspectos positivos de remuneração e geração de trabalho, com unanimidade entre empresa, moradores e relatórios de auditoria sobre os benefícios da geração de empregos e impactos positivos na renda local. Embora a renda se mostre como um fator positivo, há as insatisfações sobre oscilações de valores pagos e a falta de transparência. Foi possível observar a contribuição corporativa para o desenvolvimento sustentável, com ações sobre a vida selvagem, cujo construto identifica sinergia nas informações colhidas, com observância para a silvicultura. Por fim, foram identificados também impactos ambientais significativos como poluição sonora e emissões atmosféricas em forma de poeira.

“…Sustainable development of high-quality energy is vital for economic and social development, powering a better life and building a cleaner and more beautiful world. − As we transition toward a new energy mix with an increasingly higher proportion of green renewable energy in the global electricity system, large-scale battery storage systems will play a very important role. − At present, while battery technology is dominated by lithium-ion batteries in applications that include consumer electronics and electric vehicles, aluminum batteries (ABs) have attracted interest due to their potential low cost, intrinsic safety, abundant supply, and lower sensitivity to moisture and oxygen in the air. − Many conventional cathode designs require the use of transition metals. − Some of the key issues associated with the use of transition metals are the high production costs, scarcity of raw materials, and difficult recycling. Compared with metal cathode materials, organic cathode materials have structural diversity, designability, environmental friendliness, and sustainability. − Among organic materials, carbonyl compounds have been extensively studied and suggested as candidate cathodes for aluminum batteries because of their well-known redox reaction mechanism. , Despite significant research progress over the years, current carbonyl-containing electrode materials still have some limitations, and commercial applications still face considerable challenges.…”

Aluminum batteries with aluminum as the anode and organic materials as the cathode have continuously drawn considerable attention because of their high theoretical energy density, natural abundance, and environmentally benign nature. Herein, we have done an elaborate design work on the basis of π–π conjugated organic molecule PTCDA by a molecular engineering strategy. Introducing a sulfur atom to replace the H atom in the aromatic ring of the PTCDA molecule to form SPTCDA (sulfurized PTCDA) with p−π conjugated system can reduce the energy level of the molecule. In addition, the extension of the conjugated system makes the electrons more delocalized, which is beneficial to the improvement of the conductivity of SPTCDA. Experimental results show that compared with pristine PTCDA, SPTCDA has a more stable structure and better cycle performance, rate capability, and coulombic efficiency, as well as a higher discharge voltage plateau. To further understand the electronic structure, operating voltage, and correct redox mechanism, density functional theory (DFT) calculations were performed for PTCDA and SPTCDA. The diffusion behavior of ions on the electrode surface was also discussed. This work reveals an important molecular structure design strategy for a carbonyl cathode, in order to break the application limitations of this electrode material on aluminum organic batteries.

“…Guo et al (2022) studied the optimal economic operation problem for the IES, and the environmental consideration was modeled into a constraint. Msigwa et al (2022) provided an EED framework that functioned as accommodating to the high penetration access of wind power. A multi-objective optimization model was developed by Xu et al (2018), aiming to obtain the minimum fossil fuels and pollutant emissions of the IES, considering stochastic wind and solar power.…”

“…Based on the aforementioned discussion, this article focuses on the optimal dispatch of the IES and is intended to study the EED problem for the IES, considering the off-design conditions. Compared to the existing works (Sarfi and Livani, 2018;Xu et al, 2018;Yu et al, 2019;Dougier et al, 2021;Bartnik et al, 2022;Guo et al, 2022;Msigwa et al, 2022;Nandimandalam et al, 2022), the main novelty of this study is to take into account the impact of the off-design conditions on the energy device efficiency. The primary contribution of this article is to formulate an energy hub model, which enabled to operate with the time-varying energy device efficiency, named as the dynamic energy hub (DEH) model.…”

The integrated energy system (IES) is recognized as a promising energy utilization approach enabled to both improve the energy efficiency and reduce pollutant emissions. Although the economic-environmental dispatch (EED) problem of the IES has been widely studied, the fact that the IES is operated under off-design conditions, having a significant influence on the efficiency of energy devices, is neglected usually, resulting in the scheduled operations, for the IES could not be accurate enough in many actual situations. This study investigates the EED problem of the IES under off-design conditions. Technically, by integrating an efficiency correction process into the traditional energy hub (EH) model, a dynamic energy hub (DEH) model is first formulated for adapting itself to variable energy conversion efficiencies. Then, a deep neural network (DNN)-based efficiency correction method is proposed to predict and correct the time-varying efficiency of energy devices based on three main off-design conditions including the load rate, air temperature, and pressure. A multi-objective EED model is finally formulated for the IES, with the framework of the DEH model, aiming at establishing a trade-off between operational cost and emitted pollutants. Case studies show that the proposed approach helps in enhancing the accuracy of IES dispatch while having a good performance in both the operational cost and pollutant emission reduction.
