Hydrogen is the most abundant element in the universe.

It has the potential to fuel the economy while emitting little but clean water, and predictions of an impending “hydrogen revolution” have been swirling for decades. So far, the revolution has been elusive, but that could be about to change.

Hydrogen is on the upswing. China aims to get one million fuel-cell vehicles on its roads by 2029, and by 2023 it will have invested more than $17 billion in hydrogen. Japan is preparing to hold its second Hydrogen Energy Ministerial Meeting, an international forum launched in 2018 to promote the global adoption of hydrogen. The UK has also been eyeing the industry with the creation, in 2018, of a £20 million boost for companies in the hydrogen economy. Indonesia, as one of the largest and populated country in the planet also struggles to improve its air quality and maintain strong economic growth, commits to spend more than $25 billion in renewable and clean energy to be utilised in power generation, automotive and transportation. Hydrogen and fuel cell vehicle could be the answer for this quest.
