Re: Hydrogen is a solution and its own worst enemy

If this puts more effort in developing fuel cells and hydrogen production so that they become usable as a mobile fuel source then it is commendable. Using fuel cells in place of batteries & generators as a UPS/backup power supply is also worthwhile. Using fuel cells to power fixed infrastructure as a permanent solution is stupid. You have to use more energy in the source to destination chain due to the conversion losses at the different stages.

I suppose if we can extract hydrogen more efficiently then fuel cell do become an interesting solution when combined with solar or wind. It would be interesting to see the overall efficiency of producing 1KW of power at output for:

lead acid

lithium

fuel cell

Assuming an intermittent renewable source such as solar or wind.
