Hydrolox rockets have been making millions of gallons of new water on earth.

Even burning gasoline creates some new water.

In fact all fossil fuels! When you split the carbon parts from the hydrocarbon, most of hydrogen parts end up as water. For every tonne of CO2 that's ever been emitted, there's a corresponding mass of water for which the hydrogen part was previously sequestered.

All fossil fuels except coal, which is a pretty big one.

It's approximately pure carbon, not hydrocarbon.
