Thermodynamic Analysis of Gas Turbine Systems Fueled by a CH4/H2 Mixture
Jan 2025
Publication
In the coming years as a result of changing climate policies and finite fossil fuel resources energy producers will be compelled to introduce new fuels with lower carbon footprints. One of the solutions is hydrogen which can be burned or co-fired with methane in energy generation systems. Therefore this study presents a thermodynamic and emission analysis of a gas turbine fueled by a mixture of CH4 and H2 as well as pure hydrogen. Numerical studies Read More
Public Acceptance of the Underground Storage of Hydrogen: Lessons Learned from the Geological Storage of CO2
Mar 2025
Publication
The successful commercialisation of underground hydrogen storage (UHS) is contingent upon technological readiness and social acceptance. A lack of social acceptance inadequate policies/regulations an unreliable business case and environmental uncertainty have the potential to delay or prevent UHS commercialisation even in cases where it is ready. The technologies utilised for underground hydrogen and carbon dioxide storage are analogous. Read More
Machine Learning for Internal Combustion Engine Optimization with Hydrogen-Blended Fuels: A Literature Review
Mar 2025
Publication
This study explores the potential of hydrogen-enriched internal combustion engines (H2ICEs) as a sustainable alternative to fossil fuels. Hydrogen offers advantages such as high combustion efficiency and zero carbon emissions yet challenges related to NOx formation storage and specialized modifications persist. Machine learning (ML) techniques including artificial neural networks (ANNs) and XGBoost demonstrate strong predictive capabilities in opt Read More
