Table for water vapor heat retention, based on concentration?

I am doing some personal researching hydrogen fuel cells, and I want to information on why or why not they would be better for the environment than gasoline.

I would like to a table that compares the heat retention of water vapor to other "greenhouse gases," based on parts per million. I have found plenty of sites that say "OH GNOEZ WATER IS WORST GHG BCUZ IT CONTRIBUTES SO MUCH" but I have an itchy feeling that this is biased simply because it is a lot more abundant than other ghg.

I need either a table that compares 1 ppm water vapor to 1ppm CO2 and others (or similar equal comparison), or at least enough enough information to determine the value myself.

Any help? Thanks!
