As I understand it, if hydrogen is burned, the only “exhaust” is water. We currently send tons of carbon dioxide into the atmosphere; has anyone looked at how much water we’d be sending out, I presume as vapor, under the hydrogen economy and what effect all that water would have? I visualize something like Venus, where the planet’s surface ends up covered in a huge cloud—at least as bad as carbon dioxide—that traps in all the heat. Is that what would happen?
