Modelling the Impacts of Hydrogen–Methane Blend Fuels on a Stationary Power Generation Engine

To reduce greenhouse gas emissions from natural use, utilities are investigating the potential of adding hydrogen to their distribution grids. This will carbon dioxide grid-connected engines used for stationary power generation, and it may also impact output efficiency. Promisingly, mixtures have shown encouraging results regarding engine output, pollutant emissions, thermal efficiency in well-controlled on-road vehicle applications. work investigates effects fuel a lean-burn spark-ignited four-stroke, 8.9 liter eight-cylinder naturally aspirated commercial generation application via an model developed GT-SUITETM modelling environment. The was validated consumption, air flow, exhaust temperature at two operating modes. focus assess sensitivity engine’s brake efficiency, blends methane with 0–30% (by volume) hydrogen. Without adjusting change energy, dropped by approximately 23% when mixed 30% volume It found that increasing fueling rate maintain constant equivalence ratio prevented this drop reduced almost 4.5%. In addition, optimizing spark timing could partially offset increases in-cylinder burned unburned temperatures pressures resulted faster combustion rates added gas. Understanding effect existing systems can provide insight on utilizing as primary without need major changes engine.
