Influence of Water Content on NOx Conversion in the SCR Catalyst for Hydrogen Engines
Poster (konferens), 2026
Hydrogen Internal Combustion Engine (H2 ICE) powered vehicles can reduce carbon emissions by >95% compared to diesel vehicles. However, H2
ICE exhaust gas contains nitrogen oxides (NOx). An ammonia (NH3) Selective Catalytic Reduction (SCR) effectively converts NOx into harmless nitrogen. H2ICE’s exhaust gas contains higher water content (xH2O), affecting SCR performance in NOx conversion (deNOx). Hence, this study aims to determine how the water concentration (xH2O) in the exhaust affects deNOx independently of gas space velocity, NOx, and SCR temperature.
