What is hydrogen pollution?

Hydrogen pollution refers to the environmental impact of hydrogen production and use, particularly when hydrogen is derived from fossil fuels through processes like steam methane reforming. This method emits carbon dioxide and other pollutants, contributing to greenhouse gas emissions. Additionally, the production and transport of hydrogen can lead to leaks, which may affect atmospheric chemistry. Clean hydrogen production methods, such as electrolysis using renewable energy, aim to mitigate these pollution concerns.
