Abstract Fossil fuels, when burned in the air, release large amounts of carbon dioxide (CO2) and greenhouse gases (GHG) into the air, causing a significant increase in pollution. To reduce exhaust emission of fossil fuels on the environment, we can use natural gas (NG). Extending the lean burn area similarly reduces emissions of greenhouse gases (CO and CO2) and NOx pollutants. Temperature, pressure, and reactive mixture composition all influence measuring laminar burning speed (LBS). LBS is helpful because it (i) provides a measure of combustion efficiency and heat release rate; (ii) makes it possible to validate chemical kinetic mechanisms; (iii) provides turbine design engineers with a metric for the anticipated amount of time needed to burn the fuel charge. While studies on natural gas and hydrogen combustion near atmospheric conditions exist, very few investigations exist on high pressures in the literature. Here, we report data on natural gas/hydrogen LBS measurements up to an initial pressure of 10 atm and initial temperature of 296 K. To investigate its impact on LBS, a wide range of equivalence ratios were used. As part of the validation procedure for the results, they are also contrasted with the performance of comprehensive kinetic models.
