Modelling and simulation of H2-blended NG powered SOFC for heat and power generation applications Seema Bharati, B. Sai Mukesh Reddy, Subodh Purohit, Ibha Kalita, Dadasaheb J. Shendage, Pankaj Tiwari, Senthilmurugan Subbiah Applied Energy, 2025 This study presents a detailed modelling and simulation of a Solid Oxide Fuel Cell (SOFC) system powered by hydrogen (H₂) blended with natural gas (NG). The model, validated with experimental data from pure NG operation, predicts system performance with an average error of 1.46 %. Simulations were conducted for two cases of hydrogen blending: before and after the reformer. A 5 % by volume H₂ blend before the reformer increases power generation by 0.9 – 1 % and thermal output by 0.15 %, while post-reformer blending results in a 1.5 – 3 % increase in power generation and a 1.4 % rise in thermal output along with reduced CO 2 emission. The study includes a techno-economic analysis examining the feasibility of blending hydrogen with natural gas in SOFC systems. This analysis assesses both blending strategies' cost implications and potential benefits, providing insights into the economic viability of integrating hydrogen into natural gas for SOFC use. According to the simulation results, to align the energy cost of an SOFC system using pure NG, the hydrogen price should be 0.096 USD/kg. With the SOFC system costing 6015 USD for a 1.5 kW setup, the price of NG per kg ranges from 0.14 to 1.20 USD, resulting in electricity costs between 0.11 and 0.36 USD per kWh. Given the anticipated NG market price in 2024 of 0.89 USD/kg, the estimated power cost is 0.37 USD per kWh, which remains higher than the electricity cost from a diesel generator. In conclusion, this work highlights the potential of H₂ blending to improve SOFC performance and provides a framework for further research in sustainable energy technologies.
A Comprehensive Framework for Predictive Maintenance in Solar Photovoltaic Systems Using Contextual Deep Model Diganta Baruah, Nirban Das, Sonali Chouhan, Senthilmurugan Subbiah IEEE Access, 2025 This paper presents a framework for early fault prediction as part of predictive maintenance in solar photovoltaic (PV) systems using a context-sensitive deep learning approach. The proposed framework integrates a novel Context-Sensitive Long Short-Term Memory (CS-LSTM) regression model with a Random Forest-based classification module, leveraging both temporal and contextual features such as irradiance, temperature, time of day, and seasonal variations. Supervisory Control and Data Acquisition (SCADA) data from a 10 MW solar PV plant in India is used for model training and evaluation. The regression model estimates AC power under normal conditions, and deviations from actual measurements are flagged as potential faults. Fault classification is performed using a Random Forest model trained on imbalanced data balanced through Synthetic Minority Oversampling Technique (SMOTE), incorporating multiple fault types. Moreover, as a novel concept, an additional "Fault Impending" class has been introduced in order to provide early warning by the Random Forest classification module. Experimental results demonstrate that contextual integration significantly improves prediction accuracy, with the CS-LSTM model achieving an R²-score of 0.9741 and superior RMSE performance over baseline models. The Random Forest classifier attained the highest F1-score (0.992) in fault classification tasks. The framework also successfully predicted several faults up to 2 hours in advance, highlighting its potential for real-time monitoring.
Phenanthridium-based conjugated probe for selective detection of anionic surfactant Kannan Jamuna, Amal Tom Sebastian, Senthilmurugan Subbiah, Narayanan Selvapalam, Sivakumar Shanmugam Journal of Surfactants and Detergents, 2025 The quaternary ammonium complex of (2‐(methylthio)indeno[1,2,3‐gh]phenanthridin‐1‐yl)(phenyl)methanone (QAC) has been employed as a new and simple fluorescence sensor for detection of the anionic surfactant; sodium dodecyl sulphate (SDS), through fluorescence light‐up. The generation of electrostatic interaction and associated intermolecular arrangement between the probe and anionic surfactant is responsible for the fluorescence enhancement and subsequent selectivity towards the anionic surfactant. Concurrently, the probe was unaltered by the presence of cationic and non‐ionic systems. Utilizing this property, we were able to construct a facile and efficient method for the detection of anionic surfactants, featuring LOD values up to 1.1 μM concentrations in dimethylsulfoxide solvent. The light‐up detection was also confirmed via lifetime studies, with superior increments in average lifetime decay values (0.33–2.7 ns). The practical/real‐time applications of probe QAC as a sensor have also been investigated and successfully demonstrated via its ability to detect anionic surfactants from commercially available home usage products.
Machine learning to predict the intrinsic membrane parameters in pressure retarded osmosis for an economic salinity gradient power plant Nahawand AlZainati, Ibrar Ibrar, Ali Braytee, Ali Altaee, Mahedy Hasan Chowdhury, Senthilmurugan Subbiah, John Zhou, Adnan Alhathal Alanezi, Akshaya K. Samal Journal of Water Process Engineering, 2024 Pressure retarded osmosis (PRO) is highly investigated in the literature as one of the blue energy techniques. The PRO membrane plays a key role in harvesting the osmotic energy from a salinity gradient resource and process optimization. Therefore, a well-selected membrane will improve the power density generated in the PRO process to meet a designed power density threshold required for an economic salinity gradient power plant. In order to select a proper membrane for the PRO process, it is crucial to know its intrinsic properties, such as the membrane water permeability, salt permeability, and structural parameters, that impact the process performance. Determining the membrane's exact intrinsic parameters in a full-scale PRO module is challenging and time-consuming, and assuming constant parameters will compromise the accuracy of the results and power generation in the PRO process. This study employs artificial neural networks and Boosting-based tree models to predict the intrinsic parameters of the PRO membrane based on the minimum theoretical power density that could be predetermined and was assumed to be 5 W/m 2 in this study. The Random Forest and XGBoost algorithms demonstrate superior predictive power (R 2 = 0.97) compared to the other examined machine learning algorithms. The results reveal that machine learning algorithms can provide significant predictive power for the membrane's intrinsic parameters and power density based on the input parameters. Additionally, the algorithms were used to evaluate the feature importance of each input parameter affecting the power density of the pressure retarded osmosis membrane. • 1190 instances and 24 features PRO dataset is collected & analyzed for economic power density. • The model determines the desired membrane performance for economic power density. • The model can help researchers optimize operating conditions. • The reverse salt flux significantly impacted the power output density.
