What in your opinion should they pursue instead?IMHO, Toyota should give up on hydrogen. Sell the IP to Cummins or Ballard. Gaseous fuels were a flop in the consumer market - GM and Honda tried to sell a CNG Lumina/Malibu and Civic to the public. Only the GSA and California’s DGS bought them.
A local transit agency spent almost $10 million to install H2 infrastructure at just one bus yard. That’s including LH2 storage, cyrogenic pumps, vaporizers and CH2 storage. A majority of it is tricked in from one of the major gas suppliers.
