Hydrogen fuel could help solve the climate crisis. But it might be a fake solution.
The problems come when converting hydrogen into something we can use to fuel cars and power homes.
Right now, there are several different ways to make hydrogen:
- Gray Hydrogen – This is the way we get most hydrogen today. Gray hydrogen is made by heating natural gas, which releases a buttload of carbon dioxide into the air. Carbon dioxide is the main driver of the climate crisis.
- Blue Hydrogen – Same thing as gray, except 90% of that CO2 is stored underground. This process leaks methane, which is a greenhouse gas. Oil and gas companies like this one.
- Green Hydrogen – Renewable energy is used to make green hydrogen by using electrolysis to extract hydrogen from H20. Electrolysis: it’s not just for hair removal anymore!
- Pink Hydrogen – Electrolysis again, but powered by nuclear energy.
Blue hydrogen is, not surprisingly, the method that seems most likely to happen, in the U.S. at least, even though it seems like a pretty fake solution. Those oil bigwigs have a lot of power, and this method would allow them to keep most things the same. But is it worth switching if it doesn’t make that much of a difference?
