Technical Considerations of Hydrogen Blending into End User Infrastructures

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. Therefore, hydrogen blending demonstrations are being executed across the world to investigate the feasibility of blending hydrogen into natural gas from the end user’s perspective. The hydrogen blending demonstration work across the world will be covered, together with the challenges and opportunities on this topic.
