This study investigates the dynamic relationships between these factors in India using an Autoregressive Distributed Lag (ARDL) model on data spanning 1975–2019. Pre-analysis (Unit root, an ideal lag length, and co-integration testing) and post-analysis (serial correlation, heteroscedasticity, and recursive residuals) assumptions for ARDL model estimation were tested which came aligned with the research questions. The model robustness statistical diagnostic tests CUSUM (cumulative sum), CUSUMSQ (cumulative sum of squares), and variance decomposition testing were carried out and found to be satisfactory. The study aimed to provide comprehensive analysis of how different cereal types i.e. fine versus coarse cereals influence agricultural energy-emissions relationship and their long run effects on agricultural production-emission scenario of India. Our analysis reveals significant differences in the emissions impacts of different cereal types: while rice and wheat production contribute positively to emissions in the short run (0.06 % and 0.01 % respectively), coarse cereals demonstrate a substantial negative impact (−2.08 %) in the long run. The energy-emissions relationship shows increasing coupling over time, with elasticity rising from 0.02 % in the short run to 1.06 % in the long run. Variance decomposition analysis identifies rice production as the dominant contributor to emissions variability, accounting for 34.43 % of future fluctuations. These findings suggest that strategic crop diversification, particularly increased cultivation of coarse cereals, could significantly reduce agricultural emissions while maintaining food security. The study recommends a three-pronged approach i.e., investing in energy-efficient agricultural technologies, developing policy frameworks to incentivize coarse cereal adoption, and strengthening institutional mechanisms for technology transfer. These insights contribute to the development of targeted policies for sustainable agricultural energy transition in India.</div></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"19 ","pages":"Article 100484"},"PeriodicalIF":8.0,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657012","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}

Hydrogen has emerged as a promising alternative, with efficient underground storage being essential for its large-scale deployment. The sandstone formations are suitable, particularly with cushion gas (i.e. inert gas to maintain pressure and increase pore volume while minimizing water intrusion). In this regard, the gas-rock-brine interactions—governed by wettability and quantified via the contact angle—play a pivotal role in hydrogen trapping and mobility in porous media. This study hypothesizes that machine learning (ML) models can reliably predict contact angles under diverse subsurface conditions, thereby improving the understanding and design of hydrogen storage systems. To test this, a dataset comprising 2391 experimental data points, collected from a comprehensive review of published literature, was used to train and validate various ML models, including Extreme Learning Machine, Multilayer Perceptron optimized by different algorithm, General Regression Neural Network optimized using the Imperialist Competitive Algorithm (ICA), Least Squares Boosting (LSBoost), Least Squares Support Vector Machine, and K-Nearest Neighbors. Among these, the ICA-LSBoost model outperformed others, achieving a root mean square error of 0.5434 in training and 1.5413 in testing, along with a mean absolute error of 0.3267 and 0.9872 for training and testing, respectively.

The results demonstrated that higher DI levels, particularly 1.0 PE and 0.8+1.0 PE (moderate irrigation during vegetative and higher during reproductive stage), significantly enhanced pod and kernel yield (up to 7-fold) and haulm yield (up to 10-fold) compared to the lowest irrigation regime (0.6 PE).
