Green hydrogen
So, what is green hydrogen?
Simply put, it is hydrogen fuel that is created using renewable energy instead of fossil fuels. It has the potential to provide clean power for manufacturing, transportation, and more — and its only byproduct is water.
Where does green hydrogen come from?
Hydrogen energy is very versatile, as it can be used in gas or liquid form, be converted into electricity or fuel, and there are many ways of producing it. Approximately 70 million metric tons of hydrogen are already produced globally every year for use in oil refining, ammonia production, steel manufacturing, chemical and fertilizer production, food processing, metallurgy, and more.
Hydrogen is abundant and its supply is virtually limitless. It can be used where it is produced or transported elsewhere. Unlike batteries that are unable to store large quantities of electricity for extended periods of time, hydrogen can be produced from excess renewable energy and stored in large amounts for a long time. Pound for pound, hydrogen contains almost three times as much energy as fossil fuels, so less of it is needed to do any work. And a particular advantage of green hydrogen is that it can be produced wherever there is water and electricity to generate more electricity or heat.

A McKinsey study estimated that by 2030, the U.S. hydrogen economy could generate $140 billion and support 700,000 jobs.
