If you are pining for the hydrogen economy as RMI’s Amory Lovins seems to along with all his oil, coal, gas buddies, I am afraid the hydrogen economy has been debunked. The battery powered EV is already far more efficient than the hydrogen Fuel Cell powered EV and is moving along at a far faster clip in R/D as is often pointed out here.

If you want huge quantities of hydrogen, then steam reforming it from natural gas is probably far cheaper and is used for 95% of hydrogen supplies. When water + electricity is used, it is done with only the very cheapest electricity at rates closer to 2c/kWh which is hardly the same as the rates we all get. And if you can get electricity that cheap, water will be “free” too.

I thinks Gerardine Botte has discovered an interesting solution to a non problem. I would have thought that extracting phosphorous would be far more useful since that appears to be another finite resource we are running out of.

If she indeed gets 2x the hydrogen at one third the effort vs water which usually is up to 70% efficient in electrolysis, then this urea hydrogen is about 400% efficient. That would mean over unity. However put the released hydrogen into a Fuel Cell at 50% efficient and you get 2x the electricity that you used to split it. While this is a neat trick, I hardly think it is worth the effort or the cost of the Fuel cell plus the collection of the pee.

What about creating a way to make this more valuable?

-locations that collect urea – maybe even purchase?

$850 is a hefty investment without any solid answers on a return
