Hydrogen Blending into Residential and Commercial Combustion Applications
Blending green or blue hydrogen into the natural gas infrastructure is considered a promising way to reduce the greenhouse gases thus to combat climate change. However, due to significantly differing characteristics of hydrogen and natural gas, such as flame speed, adiabatic flame temperature and stability limits, the combustion performance of hydrogen/natural gas mixture differs from pure natural gas. From the perspective of residential end users, a key question is: how much hydrogen can be injected into the pipeline natural gas without influencing the performance of the residential burners? This presentation focuses on the technical perspectives regarding blending hydrogen into residential and commercial applications. The impact of hydrogen on natural gas combustion systems and future expectations will be covered.
