Toyota is taking on the hydrogen fuel-cell car haters — including Elon Musk

4. SHOW ME THE MONEY !!!!!

Or at least show me the bill. If this can really compete on a cost basis, Let us see it.

Hydrogen energy technology is only a different form of energy storage, competing with batteries, compressed air, or pumping water up hill. It is not a primary energy source.

Solar pv panels were not competitive except on a special needs situation until the panel price dropped by 90% in the last 5 years. I have a hard time seeing the practical generation, storage and conversion back to usable energy forms of hydrogen being cost competitive with other existing technologies.

Converting methane from biodigesters to hydrogen may not be the best use of the energy available. Why not just burn the methane in a co-generator without all other processing? And the methane (natural gas) from biodigesters has to compete with the Fracked well sources which is another whole "show me the money" issue.

(a biodigester captures methane from contained decomposing organic waste like the cow poop above, or organic garbage like spoiled food, by the way.)
