Planning HSC expansion is difficult due to diverse technical options in H₂ production, transportation, and storage, as well as the intertwined relationship between HSC and the power system (PS). Evolving carbon policies add further complexity, yet their impact on a jointly planned HSC–PS system is not well understood. In this study, we develop a mixed integer linear programming model to optimally expand the HSC and PS, accounting for various technological options. We systematically analyze and compare the impact of three representative carbon policies (non-tradable carbon allowance, carbon tax, and cap-and-trade) on the integrated system. Our results show that under all analyzed policies, blue H₂ plays a pivotal role in decarbonization when CCS costs are moderate. When blue H₂ is considered and its cost is no more than 30% higher compared to the base level, HSC–PS interactions are only pronounced in deep decarbonization scenarios. Although carbon taxes grant firms more flexibility than non-tradable carbon allowances, they incur higher costs to reach similar emission cuts. For price-taking participants in a cap-and-trade system, the carbon price primarily dictates emissions and allowance trading decisions, while pre-assigned allowances influence the total cost. These findings offer valuable guidance for companies and policymakers seeking to design effective carbon regulations and invest strategically in HSC and PS infrastructure.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"409 ","pages":"Article 127455"},"PeriodicalIF":11.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171150","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}

To overcome this fundamental barrier, we introduce E2AY-Net, an end-to-end deep learning framework that transforms urban facade PV assessment from slow multi-stage simulation into instantaneous spatially-resolved energy yield generation.

This work addresses this gap by developing a mesh-free PINN framework that embeds the governing transport equations of multicomponent channel flow, including oxygen consumption, directly into the learning process. Unlike conventional artificial neural networks (ANNs), the proposed PINN does not require labelled CFD training data. In this work, CFD data are used for benchmarking and validation, while the PINN training itself does not rely on CFD field solutions in the interior of the computational domain, and the PINN training itself is driven solely by the embedded governing equations without labelled CFD target fields. The model is evaluated with respect to two core research questions: (i) Can a PINN accurately reproduce the coupled flow and species transport fields in a PEMFC gas channel? and (ii) Can the learned physics be leveraged to predict performance for previously unseen channel widths? Results show that the PINN reproduces CFD reference fields with high accuracy and substantially outperforms ANNs in generalizing to channel widths not included in training. Moreover, the PINN-based design study achieves a computational time reduction of approximately 83.9% compared to full CFD simulations.

These contracts guarantee individual electricity rates to households with flexibility potential, such as thermal or electrical storage and the thermal mass of buildings, in exchange for granting aggregators operational control. The household-specific contracts are determined and evaluated through a three-step process, combining deterministic and stochastic modeling. First, an optimization problem for the operation of home energy management systems is formulated. The proposed model incorporates the thermal inertia of buildings as a flexibility potential, an aspect frequently overlooked in existing studies. Then, a Monte Carlo simulation of household parameter combinations is run, followed by a quantile regression prediction of household-level low-price guarantees. The simulations of 9404 household configurations in Germany demonstrate that aggregator-managed flexibility consistently lowered electricity costs by an average of 7.36% (2.5 ct/kWh) compared to static tariffs, with 78.4% of households achieving rates below the competitive retail benchmark. Aggregators also realized higher profitability on a per-household basis across all three analyzed years compared to scenarios without flexibility control. Our results demonstrate that building parameters, particularly thermal inertia, substantially influence the available flexibility potential and should be considered a key factor in the design of household-level guarantee contracts. The study contributes to understanding and quantifying uncertainty in dynamic tariffs for households, aiming to advance the utilization of household demand response potential in modern power markets.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"409 ","pages":"Article 127430"},"PeriodicalIF":11.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171149","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}

Locational Marginal Emission Rates (LMERs) effectively capture the change in emissions associated with a change in demand. This paper introduces a computationally efficient LMER calculation algorithm that considers reserve requirements and network constraints in the economic dispatch model. Unlike locational marginal prices (LMPs), which can be directly derived from shadow prices expressed in $/MWh, calculating LMERs requires identifying marginal units that adjust their outputs in response to infinitesimal changes in system parameters. The LMER calculation algorithms also compute the incremental output changes of these marginal units and utilize these output changes, combined with the respective emission rates to compute LMERs accurately. However, the inclusion of reserve requirements, which are essential in modern electricity markets to address the uncertainties introduced by contingencies and significant intermittent generation, complicates identification of marginal units and calculation of their corresponding output changes in response to the locational demand changes. Thus calculating LMERs become increasingly complex. The proposed algorithm for the calculation of LMERs considering the reserve requirement systematically identifies marginal units and their corresponding output changes to calculate LMERs. This algorithm has been tested on both a four-bus system and a synthetic Texas Test System to show its efficiency and validate its accuracy. Furthermore, this algorithm is examined with different levels of reserve requirements and hence analyzes the impact of reserve requirements on marginal units and LMERs.</div></div>","PeriodicalId":246,"journal":{"name":"Applied Energy","volume":"409 ","pages":"Article 127439"},"PeriodicalIF":11.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076596","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 addresses these gaps by developing two complementary and generalizable frameworks: (i) one for evaluating long-term WEC power performance under realistic, time-varying sea conditions, and (ii) another for assessing UUV docking feasibility. The frameworks were demonstrated using the field-deployed TigerRAY WEC–UUV system with 2024 wave data from NDBC buoy station 42,036 on the U.S. Atlantic South Coast.
