Although limited research has been explored on the oxidation of butanol compared to that of methanol and ethanol. In the present work, a bimetallic organic framework (CoZn-MOF) was employed to disperse Pd nanoparticles and was utilized for the first time for butanol oxidation in basic media. The CoZn-MOF was synthesized through the coprecipitation method, followed by electrodeposition of Pd nanoparticles onto the nanocomposite. The as-prepared catalyst material was characterized by SEM, EDS, XRD, and FT-IR analysis. Electrochemical analysis, including cyclic voltammetry (CV), electrochemical impedance spectroscopy, and chronoamperometric studies, revealed that the Pd@CoZn-MOF/GCE showed outstanding electrocatalytic performance, higher current density (0.01895 A cm<sup>−2</sup>), excellent stability (350 cycles) and durability (3000 s), and strong resistance to catalytic poisoning from carbonaceous species during butanol electro-oxidation, which is due to the effective synergy between CoZn-MOF and Pd nanoparticles, which enhances electron transfer. The findings proved that the newly developed electro-catalyst is a promising alternative to traditional Pt-based catalysts in DACs.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high cost of installing wind Turbine (WT), MT, PV panels, and Energy Storage Systems (ESS), along with the necessary infrastructure, makes it a costly solution, particularly for small-scale or residential applications. To address these challenges, this paper proposes a hybrid approach for the economic assessment of a grid-connected hybrid Wind-MT-PV-EV system. The proposed method combines the Sand Cat Swarm Optimization (SCSO) algorithm with the Attention-Based Sparse Graph Convolutional Neural Network (ASGCNN), forming the SCSO-ASGCNN technique. The goal is to enhance the economic performance, cost-effectiveness, and dynamic control of the hybrid system. The SCSO algorithm is employed to optimize energy management (EM) and improve the operational efficiency of the system, while the ASGCNN is utilized to predict the forecast patterns of energy generation and consumption. The proposed method is implemented on the MATLAB platform and evaluated against several existing approaches, including the Adaptive Genetic Algorithm (AGA), Proximal Policy Optimization (PPO), State-Action-Reward-State-Action (SARSA), Deep Reinforcement Learning (DRL), and Modified Dragonfly Algorithm (MDA).

Beyond widely used Li-ion batteries and Pumped Hydro Energy Storage (PHES), Advanced Adiabatic Compressed Air Energy Storage (A-CAES) offers promising potential, although it is not yet commercially available in Europe. This study evaluates the environmental impacts and exergy demand of daily electricity discharge over 30 years for both 10 and 100 MWe A-CAES systems. The 10 MW system is compared to Li-ion batteries (NMC/Graphite, LFP/Graphite, and NMC/LTO chemistries), while the 100 MW system is compared to PHES. Analyses are conducted at both endpoint (human health, ecosystems, and resources) and midpoint levels (climate change and exergy demand). Results show that the 10 and 100 MW A-CAES systems have similar or higher impacts compared to their counterparts when coupled with the French electricity grid mix. This is primarily due to the impacts associated with the electricity to be stored and round-trip efficiency losses: Li-ion batteries and the PHES system have higher efficiency (79.1% and 82%, respectively) than A-CAES systems (54.4% for the 10 MW and 70% for the 100 MW). However, when coupled with renewable sources, which have lower impacts than the French grid mix, A-CAES systems are more beneficial due to lower equipment life cycle impacts, particularly for the 10 MW A-CAES (equipment impact: 11 gCO<sub>2</sub>eq/kWh returned to the grid) compared to Li-ion batteries (equipment impact: 54 gCO<sub>2</sub>eq/kWh returned to the grid).
