Large power station alternators are hydrogen cooled.. that's right the whole alternator is filled with hydrogen. you have to monitor how close you get to the upper explosive limit.
at a tenth the windage and ten times the heat transfer capacity of air, the stator and rotor can be a hell a lot closer and magnetic coupling more efficient therefore massive savings in construction and more efficient energy conversion to electrical energy
