Hydrogen emerges as a way to help people get out of coal, and Australia at the perfect place to do much of it.
The idea is to convert other sources of energy such as wind, solar or coal into liquid fuel that could easily be stored and shipped to countries that can not make enough renewable energy.
Australia's chief scientist, Alan Fickell, says hydrogen exports could reach $ 1.7 billion and provide 2800 jobs by 2030 with proper policies.
It calls shipping.
What happens in our way? And is it really good to be true?
