This is potentially a stupid question, but I will ask... Water vapor is a potent greenhouse.
The H2 crowd markets their products/tech as "zero emissions." Why does hydrogen-as-a-fuel seemingly get a pass on water vapor emissions, despite them being a significant greenhouse gas?
- credit_guy 3y agoBecause water vapor is condensable. It has a very short half life in the atmosphere. Depending what source you find, it ranges from 4 to 9 days. That's days. CO2 has a half life of more than one century.
