Green hydrogen could be the fuel of the future. Here's why it's not yet a silver bullet
CNN
As the climate crisis escalates, the world is banking on carbon-free energy to achieve a future with zero greenhouse gas emissions, or a net-zero future, where we remove just as much greenhouse gas from the atmosphere as we emit.
One potential form of clean energy is green hydrogen, which is derived from renewable sources like water, rather than fossil fuels, and can be used to power heavy industry and fuel large vehicles, like planes and ships. Facilities to produce this cleaner form of the gas have popped up across the globe -- in the United States, western Europe, China, Australia, Chile and South Africa, among other countries. The burgeoning global green hydrogen market is projected to be worth $11 trillion by 2050, by Goldman Sachs' estimates.
