“What we’re concerned about is the combustion of hydrogen,” says Alex Jasset from Physicians for Social Responsibility – Los Angeles. “Because that’s where the [nitrogen oxides] emissions come from. It’s where a lot of the explosion risks come from.” Nitrogen oxides, or NOx emissions, are some of the notorious ingredients in smog. And since hydrogen combusts at higher temperatures than methane, that chemical reaction is more likely to happen with a hydrogen plant, leading to an increased likelihood of air pollution from the plant.
