Would hydrogen powered cars cause icy conditions during wintertime?

Question

They say hydrogen powered vehicles would only give off water vapor through exhaustpipe. Wouldn't the water vapor condense and then form ice on the roads during cold weather? Could result in some wicked roads is my line of thinking.

Answer 1

The amount of water is negligible.  However, the dream of hydrogen fuel cells is pretty far away.  Electric cars are ready now and should be what the industry focuses on.

Answer 2

YES.

Answer 3

Gas also produces water vapor through the exhaust.

Answer 4

the water vapor could condense, but it won't condense on roads in cold winters. (think about it, water vapor=heat=warmer than surrounding air=floats up)

Answer 5

The byproduct H20 coming out of the tailpipe is so minute that it  evaporates b4 it can do any harm. For complete information go to http://www.water-hybrid-cars.info or http://www.water-4-gas-cars.com

Answer 6

Our present cars have water vapor  & CO2 comeing out the tail pipes.

Answer 7

The main problem in very cold weather is getting the water to leave the tail pipe. It tends to ice up in the drain line.

That has been solved, but now they emit flakes of snow in cold weather.

It will be nothing in comparison to the snow blowing across the highway. We can ignore this as a problem.

Answer 8

Gasoline engines produce only slightly less water vapor than a hydrogen ICE would. A hydrogen fuel cell car could produce less water vapor.
