Although praise is being sung from all corners about the potential savior hydrogen, there is a major issue that is often forgotten: How do you produce it and at what cost? Energy Bulletin points out:
Hydrogen isn’t an energy source – it’s an energy carrier, like a battery. You have to make it and put energy into it, both of which take energy.
Coming up with a way to produce it that is climate neutral and economically efficient is a lot more challenging than you might think.
