I wonder how efficient using hydrogen could be. Like would it be the same as stockpiling and distributing gasoline would be. It'll be nice if the power from dams is enough to generate a good amount, especially for regions with fluctuating weather patterns.
This is a very interesting topic.
This article says that most of the world's hydrogen is made from methane, which results in carbon dioxide being released to the atmosphere, as opposed to electrolysis which is entirely clean. I personally think countries should be investing in nuclear energy and bringing the costs of electricity down to make hydrogen more attractive.
Aw that's bummer. I'm assuming electrolysis is more expensive. If only there's something that can be done to all the carbon dioxide released in the process.
