Another breathless article about the wonderful earth-saving hydrogen revolution that’s been just around the corner since the 1980s.
Here’s the breakdown on the hydrogen swindle. It’s all just basic science.
1) Usable hydrogen does not occur naturally on Earth, you have to make it. There isn’t any hydrogen well, there aren’t any hydrogen mines. The easiest way to make large quantities is something called steam reformation but you can also electrolyze water.
2) Since you have to expend energy to make usable hydrogen, hydrogen is not really a fuel like oil or coal, hydrogen is a way to store energy produced in some other way. You don’t get all the energy you spent back out, either; there’s some loss involved. So you can burn polluting fossil fuels to make hydrogen from natural gas, and actually create more pollution and waste than you’d make running directly from the fossil fuels without any hydrogen being involved.

3) Sure, you can make hydrogen using a sustainable energy source like solar or wind. But comparing stored hydrogen to other energy storage technologies, such as batteries, you find that hydrogen has extremely poor energy density – that is, a battery that can store just as much energy as a hydrogen tank of a given size is significantly smaller than the hydrogen tank – and if you are using the latest technologies, the battery will be lighter and safer as well.
So while hydrogen has many wonderful properties, IT IS NOT A FUEL and it isn’t even a very good energy storage medium (at least compared to batteries) for most purposes. And we haven’t even talked yet about the expense and difficulties associated with storing and using it!
The truth is Big Oil likes hydrogen because any so-called “hydrogen economy” would necessarily be built and run on petroleum and natural gas. And another truth seems to be that you can sell any pseudo-scientific energy quackery in California, since they’ve already been around this barn twice now and are apparently still falling for the same nonsense.
