It is predicted that hydrogen will become a major source of energy in the coming decades. For this to happen, an infrastructure needs to be built and developed. A full network for hydrogen production, storing the hydrogen, transporting the hydrogen and refuelling hydrogen-powered systems will need to be constructed. To create this, the estimated cost will be in the trillions of dollars. Different countries have set up plans and organizations to organize the building of the infrastructure. There are many barriers to overcome, such as cost, government policy and public opinion. It will lead to a transition from oil to hydrogen, and reduce the world's dependence on fossil fuels.
