A Comprehensive Review on the Hydrogen–Natural Gas–Diesel Tri-Fuel Engine Exhaust Emissions
Aug 2024
Publication
Natural gas (NG) is favored for transportation due to its availability and lower CO2 emissions than fossil fuels despite drawbacks like poor lean combustion ability and slow burning. According to a few recent studies using hydrogen (H2 ) alongside NG and diesel in Tri-fuel mode addresses these drawbacks while enhancing efficiency and reducing emissions making it a promising option for diesel engines. Due to the importance and novelty of this the contin Read More
Coalition Analysis for Low-carbon Hydrogen Supply Chains Using Cooperative Game Theory
Feb 2025
Publication
Low-carbon hydrogen is a promising option for energy security and decarbonization. Cooperation is needed to ensure the widespread use of low-carbon energy. Cooperation among hydrogen supply chain (HSC) agents is essential to overcome the high costs the lack of infrastructure that needs heavy financial support and the environmental failure risk. But how can cooperation be operationalized and its potential benefits be measured to evaluate the im Read More

A Comprehensive Analysis of Characteristics of Hydrogen Operation as a Preparation for Retrofitting a Compression Ignition Engine to a Hydrogen Engine
Mar 2025
Publication
Hydrogen is a carbon-neutral fuel so in theory it holds enormous potential. The use of hydrogen as a fuel for traditional internal combustion engines is becoming increasingly prominent. The authors now have the opportunity to retrofit a single-cylinder diesel research engine to an engine with hydrogen operation. For this reason before that conversion they prepared a comprehensive review study regarding hydrogen. Firstly the study analyzes the Read More
