Hydrogen vs. Battery Electric Cars

Without a countrywide scale of investment, as some in Japan propose, it feels like hydrogen powered vehicles would be limited to the fringes, such as air freight or long haul freight.  Hydrogen fuel cells for Air freight would need to complete against airships in terms of cost and safety.
With hydrogen powered fuel cells being around 8x the cost of battery to run cars, it's not going to take off in the consumer sector without a government using taxes to pay most of the generation and transmission costs of hydrogen.
Far better to invest in battery technology for the next few decades and build up renewable and green energy generation capabilities and focus hydrogen on solving the niche areas where battery powered cars are currently limited (although those limits are continuously being eroded)
