Both H2 and CH4 are highly flammable gases. Hydrogen, in particular, has a wide flammability range and can cause explosions if not properly managed. Methane, while less volatile than hydrogen, is a potent greenhouse gas with a global warming potential significantly higher than carbon dioxide.
Methane leaks during production, transportation, and usage contribute to climate change. Unchecked hydrogen leaks can also indirectly impact the environment by prolonging the life of methane in the atmosphere.
Stricter environmental regulations demand more rigorous monitoring and control of gas emissions and leaks, necessitating advanced sensor technologies.
