Some thoughts and questions sparked by the first presentation

  1. What sort of infrastructure would be required to support a hydrogen-based economy? Dan Nocera is aiming to jump-start distributed hydrogen production in the developing world, thereby bypassing the vested interests of the large oil companies. What sort of infrastructure would be required in India? What about in this country, if we were able to strong-arm the oil companies?
  2. How do currently operating hydrogen-fueled vehicles store the hydrogen they use, or do they use on-board reforming?
  3. Nocera claimed that he could produce hydrogen at 300 atm pressure for storage in aluminum tanks on the roof. Would such tanks be useful for transportation, too? What sort of energy penalty does one pay for generating at high pressure?
  4. Does it make sense to stick with hydrogen, if that it what is generated directly by photodissociation of water, or would it be better to react that hydrogen somehow to produce a liquid fuel? What would be the energy penalty and how would it compare to the pressure penalty?
