What is hydrogen?

Hydrogen is one of the most abundant elements on earth and has the highest energy content of any common fuel by weight.

 

When combusted, hydrogen produces water vapor, not greenhouse gas emissions. It can be safely produced, transported, stored and blended into the existing gas grid to help decarbonize the pipelines. 
Hydrogen has been safely used for decades in aeronautics to fuel space exploration and in the industrial sector to process food, manufacture electronics, and make glass and metal. In addition, Europe, Asia, and Australia are scaling up their use of hydrogen to combat climate change and lower carbon emissions.
