The PHEV is much more likely to be discontinued than the Fuel Cell due to the way ZEV and TZEV credits are calculated, applied, and restricted.
That would be a tragedy. Given that the most common process for producing Hydrogen is natural gas reformation (fossil fuel) which produces hydrogen and CO2. The process costs 3X the price of natural gas. The electrolysis of water method is even more costly. Only 1% of the hydrogen produced in France comes from the electrolysis process. Data from Planete Energies.
A Kilo of H2 costs $13-16, per the California Fuel Cell Partnership, that equates to $6-7/ gallon gas. This is why FC drivers are given a $15,000 fuel allowance for 3 years. Hydrogen is scarcely available in CA and virtually unavailable elsewhere. There was even a little disruption in the supply awhile back and our friends with a Mirai were given a loaner car and Toyota offered to make their car payment for 6 months as compensation.
They have to sell 3.5 PHEV's in every Section 177 State in order to get the same amount of credits that 1 FCX sold in CA earns. And they can only utilize TZEV credits for part of the minimum they are required to have.
How many credits does Honda need? It is painfully obvious that when a group of elected or appointed geniuses get together and devise a plan, there is no guarantee that it will be a good plan.
And on a good day, our Clarity Electric will easily exceed 100 miles of range. Not hauling around an unneeded gas engine (and associated systems) allows it to get nearly double the PHEV range with only 50% more batteries.
