Mostly Harmless
Fuel cells for cars have been discussed extensively here and the common sentiment is that they are clearly inferior to electric cars. However, I haven't seen much nearly as much discussion about hydrogen with regard to clean energy storage on an industrial scale.
I read an article today on a local newspaper where the CEOs of two large European energy companies were interviewed and both mentioned hydrogen as a future clean energy storage medium. To my astonishment, large batteries were not even mentioned even though I know that one of the companies experimented with batteries already ~5 years ago.
Ever larger battery projects seems to be popping up around the globe but I haven't noticed articles about large scale hydrogen-based energy storage solutions. Anyone care to give a link to a relevant article or give a quick summary about the viability of hydrogen in clean energy storage in comparison to batteries?
As I understand it, the logical bottleneck for Hydrogen use is the inefficiency of production. It requires the use of energy to produce the Hydrogen.
By comparison, renewable plus battery is very lean as there is no energy loss to create the end product once the generation and storage is in place.
Add in the explosive nature, the difficulty to contain the second smallest atom in a bottle, additional energy required for compression and cooling and whatever else is needed, plus the complexity of making it safe. The valid arguments against it pile up pretty quickly.
Every indication, to me, is that Big Oil is the one pushing for Hydrogen because they would be the source of the raw material from which it would be derived. I'm sure they also push for petroleum powered Hydrogen production facilities as well. Another good reason not to do Hydrogen.
