Hydrogen
Using fossil fuels or clean electricity, we can produce hydrogen gas, which can be stored, transported, and burned to provide power. Unlike most fuels, hydrogen does not produce the greenhouse gas carbon dioxide (CO 2) when burned: instead, it yields water. This means that burning hydrogen fuel does not contribute to climate change.
