Another reason to wheel out the hydrogen maths.
A Sheffield company have come up with a home electrolyser. You take electricity into your house, lose 70% of the energy converting it to hydrogen, then burn the hydrogen to make it back into electricity.
You couldn't make it up.
The real push is that it makes hydrogen vehicles seem more viable. The company have adapted a Ford Focus to run on hydrogen. I've done an emissions calculation.
For the results (and another trumpeting of the basic arguments against hydrogen as a vehicle fuel), see my new post on The Sharpener, Hydrogen Car Emits Like a Hummer.
