RE: The Technological Features Of A Post Oil City

in #technology7 years ago

Great post, what's you take on hydrogen powered vehicles (hydrogen fuel cells)? I think a combination of mass transit, higher densities and electric vehicles will be the future. Hydrogen cells will be used for independent vehicles that need distance and possibly planes. Boats could also use hydrogen or solar and batteries in the ballasts.

Sort:  

I think that we will use every available alternate technology including hydrogen fuel cells.

The downside of these things though are:

  • hydrogen is leaky (hard to contain),
  • light and does not have much energy density unless stored at high pressure or liquefied,
  • embrittles metals which is a bad thing

This is why I think liquid fuels like biodiesel or algae oil fuels will probably win out over hydrogen.

Storing electricity in batteries is currently about 3 x more efficient than using it to create hydrogen for fuel cells, then generating electricity from the fuel cells. See here
