Can hydrogen save us from global warming?

Answer 1

while hydrogen can contribute to efforts to combat global warming, it should be seen as part of a broader strategy that includes energy efficiency, renewable energy development, and other sustainable practices. Transitioning to a low-carbon economy will likely require a combination of technologies and approaches.

Answer 2

Yes, hydrogen could save us, if we could find an easy and cheap way to obtain hydrogen from water (H2O), then hydrogen is a pure and green fuel with no emissions except water vapor. Water vapor would briefly remain in the atmosphere, but it soon builds into clouds and falls as rain, so it would not contribute to global warming the way carbon dioxide is. Cars and industry could run on hydrogen, as could electricity power stations.
