Techniques for generating electric power for well site operations include processing a hydrocarbon fluid produced from a subterranean formation, through a wellbore, and to a terranean surface into at least one acid gas; processing the at least one acid gas into hydrogen; generating, with the hydrogen, electrical power from a hydrogen engine; and providing the generated electrical power for use or storage to power at least one electrically-operated machine to perform at least one well site operation.

A process and gas processing plant configured to contact a produced gas stream with a lean aqueous solution comprising i) water and ii) an amine diol comprising a trisubstituted amine diol, a heterocyclic amine diol, or a combination of trisubstituted amine diol and a heterocyclic amine diol, to produce a treated gas stream comprising methane and a rich aqueous solution comprising the one or more impurities, the amine diol, and the water.
