Yet, assumptions on hydrogen imports vary widely across existing studies—ranging from fully flexible to fixed import volumes — often neglecting the modalities of future hydrogen trade such as long-term contracts (LTC). This paper addresses this gap by investigating the implications of Take-or-Pay (TOP) rates in hydrogen LTCs on a decarbonized European energy system. We employ a numerical model that optimizes generation capacity, storage and infrastructure investment, and dispatch decisions for the European power and hydrogen sector in 2050, explicitly incorporating TOP obligations in hydrogen LTCs. Our findings show that varying TOP-rates induce significant shifts in cost-minimal infrastructure requirements of the energy system. These shifts underscore the necessity to account for the degree of import flexibility in planning assessments for future energy systems relying on hydrogen imports. Additionally, we show that reduced import flexibility imposed by high TOP rates is balanced predominantly by increased hydrogen storage and withdrawal capacity while import capacity decreases. By simulating dispatch decisions for 35 weather years for the energy systems planned with representative weather, we find that systems planned with high TOP-rates exhibit a lower reliability when weather characteristics during operation differ from the planning stage.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"389 ","pages":"Article 125784"},"PeriodicalIF":10.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To bridge the gap between nationwide macro-level targets and localized micro-level plans, a meso-level approach is essential, considering regional diversity, market dynamics, and customer-centric factors. To address these limitations in meso-level planning, this paper proposes a customer-segmentation approach coupled with a probabilistic Monte Carlo Simulation to identify charger requirements in the cities across the Australian capital. This paper employs a K-means clustering algorithm to classify EV customers, leveraging prioritized features derived from a Random Forest Classifier based on available models in regional markets. Regional uncertainties in EV plug-in behaviors are collected from Australian scenarios to capture the inherent variability in charging patterns and accurately reflect the local demographics influencing EV adoption and usage. The results indicate the need for installing 1239 regular and 235 fast-charging ports, with a projected 29.53 % increase in charging ports by 2040 due to population and vehicle sales growth. Additionally, comparing with existing reports reveals that neglecting customer plugin behaviors and vehicle types can lead to an inaccurate estimation of charger requirements, resulting in significant investment losses. The findings underscore the importance of incorporating customer segmentation and regional variations into EV infrastructure planning to optimize resource allocation without costly mismatches.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"389 ","pages":"Article 125742"},"PeriodicalIF":10.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, based on this model, the event-triggered optimal coordinated operation is introduced, leveraging on-site data measurements to achieve real-time energy management. In addition, a tailored coordination method is explored for optimal distributed dispatch of STS-RRs. To support secure operation, the nonlinear autoregressive exogenous network-based parameter estimator is also proposed, which adapts to the model and event-triggered operational methods with ultra-high accuracy. Synthetically, a digital twin-fusion smart energy supervision platform is implemented to simulate the actual system, to collect and store field data stably, to validate the proposed methodologies, and to evaluate the system efficiency. Simulations and field tests on real-world STS-RRs in South China are carried out, where secure operation is guaranteed. The results highlight a high fidelity of the digital twin, with practical modeling and extra-small mean absolute error for the proposed estimator, less than 0.045 MPa.

This work investigates three methods of integrating empirical capacity fade models into a machine learning framework to improve the model’s accuracy and uncertainty calibration when generalizing beyond the training dataset. A critical element of our framework is the end-to-end optimization problem formulated to simultaneously fit an empirical capacity fade model to estimate the capacity trajectory and train a machine learning model to estimate the parameters of the empirical model using features from early-life data. The proposed end-to-end learning approach achieves prediction accuracies of less than 2 % mean absolute error for in-distribution test samples and less than 4 % mean absolute error for out-of-distribution samples using standard machine learning algorithms. Additionally, the end-to-end framework is extended to enable probabilistic predictions, demonstrating that the model uncertainty estimates are appropriately calibrated, even for out-of-distribution samples.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"389 ","pages":"Article 125703"},"PeriodicalIF":10.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to develop ready-to-use guidelines for optimizing the heating curve with energy-efficient adjustments that improve room comfort and prevent suboptimal user changes, all without requiring additional sensors like room thermostats. Based on interpretable linear models, estimated on 3995 air-to-water heat pumps, located in Central Europe, we select the least energy-intensive heating curve shift for each outdoor temperature, needed to meet room thermal comfort.

The present research put forward an enhanced design for a suction-type annular bipolar plate structure and devised a 3D non-isothermal model to explore the consequences of modifying the cathode runner structural parameters of annular bipolar plate on the cell's performance output as well as the internal dispersion of heat, water, and oxygen. In addition, three cathode runner configurations—straight runner/fan-shaped rib, fan-shaped runner/straight rib, and fan-shaped runner/fan-shaped rib—were designed and their effects examined. The findings showed that the fan-shaped runner/straight rib configuration displayed the best temperature control capability (Hot spot temperature at cathode side exit: 36.3 °C, average temperature at the center surface of the film: 302.4 K, uniformity inside the cathode flow channel: 99.8 %) and achieved the maximum power density (contact resistance: 0.098 Ω-cm²) at the same current density conditions (0.8 A/cm²). The performance of the straight runner/fan-shaped rib was marginally inferior to that of the fan-shaped runner/straight rib, while the fan-shaped runner/fan-shaped rib configuration presented the poorest performance. Owing to the interaction of high air velocity and high electro-osmotic resistance inside the cathode runner, the fan-shaped runner/fan-shaped rib bipolar plate (relative humidity: 82.2 %) was prone to water loss from the fuel cell membrane electrode, thereby having an impact on the cell performance. Conversely, the fan-shaped runner/straight rib setup (relative humidity: 46.2 %) manifested the most excellent performance and kept an optimal water content.
