This study introduced hydrogen through the inlet manifold, while biodiesel produced from &lt;em&gt;A.pinnata&lt;/em&gt;was delivered into the combustion chamber. The primary objective related to the investigation seeks to examine the issues of oxidative stability within biodiesel mixes along with the accompanying trade-offs between engine efficiency and greenhouse gas emissions, contributing to the United Nations Sustainable Development Goals (SDGs), particularly SDG7 (Affordable and Clean Energy) and SDG13 (Climate Action). In the current investigation, all tests were carried out on a single-cylinder, four-stroke turbocharged direct injection diesel engine fuelled with and without including an organic antioxidant into biodiesel-diesel injected fuel with induced hydrogen-air gaseous fuel blends. This research demonstrates how an organic antioxidant addition can be utilized to overcome the oxidative stability constraints within biodiesel, increasing the feasibility of hydrogen-biodiesel dual-fuel systems for energy-efficient applications. The experimental approach involves the utilization of three testing fuel specimens: diesel, APBD20, and APBD20+H&lt;sub&gt;2&lt;/sub&gt; at varying flow rates of 10 L/min, 12 L/min, 14 L/min, 16 L/min, 18 L/min, and 20 L/min. Crucial performance parameters including brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) have been investigated. Different greenhouse gas emissions, including oxides of nitrogen (NOx), carbon monoxide (CO), unburnt hydrocarbon (UBHC), and smoke opacity have been evaluated across all loading circumstances.

A stationary LH<sub>2</sub> tank with a volume of 5.6 m<sup>3</sup> with multilayer insulation (MLI) and high vacuum conditions was modeled to simulate heat ingress and resulting BoR.

Historical temperature data were leveraged to predict seasonal variations in heat ingress and BOG generation. Additionally, the system was modeled and simulated using the software Ansys Twin Builder to accurately replicate the dynamic behavior of the tank under varying thermal conditions. An LH<sub>2</sub> tank is modeled using Python language and then interfaced with the twin builder and for the BOG collection tank the Modelica's vessel component is used.</div><div>The simulations demonstrated that the BoR exhibited significant fluctuations across the seasons, with the highest rates observed during summer due to increased ambient temperatures and reduced during winter due to lower thermal gradients.

The time-series analysis provided precise insights into the daily patterns of temperature-driven boil-off, validating the predictive capability of the model. The developed model successfully quantified the impact of seasonal temperature variations on LH<sub>2</sub> boil-off in stationary tanks, offering a robust tool for optimizing insulation strategies and BOG management. The findings underscored the importance of Thermal Management Systems (TMS) for minimizing hydrogen losses in the future, thereby enhancing the viability of LH<sub>2</sub> tanks in airport fuel for hydrogen-powered aircraft.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"128 ","pages":"Pages 725-731"},"PeriodicalIF":8.1,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
