Why do methanogens produce methane?

Doesn't this just cost them energy and they excrete it? What's the motivation?

Also how do chemolithotrophs get NADH?

nope, the reaction CO2 + 4 H2 -> CH4 + 2H2O has a deltaG of -170.

On your second question, I would say it depends on the exact organism and the pathway they use
