Making h2 at less than $2/kg from renewables is achievable today. 300 bar at $2. Lh2 at $2.50.
Sales prices are much higher because capacity is still low, and toyota bundles some free to its fcev customers, and sales volumes are low such that a high profit margin is required to pay for filling infrastructure.
$2/kg is equivalent range in a fuel cell compared to 1$/gallon gasoline. That is much less than refinery sales prices of gasoline or diesel.
I’m assuming the concept they’re thinking of goes something like: Using renewable energy like solar and wind to convert water (or some other source of H2) into liquid H2 for the increased energy density compared to charging lithium batteries or equivalent with those same renewables.
There’d be tons of energy loss along the way, but since renewables are effectively “free energy,” I can see that it would work in theory.
Where are you finding this cheap renewable H2?
Or is this a theoretical future development?

Consumer prices have chicken vs egg problem.

Right, hydrogen only makes economic sense if the fuel is free because the whole system efficiency stinks compared to BEVs.
