Next down the line is hydrogen, which comes with a shitload of issues.
No argument there. But other methods all have their own shitloads -- it just depends on which shitload the designers dislike the least.
you will find little love for hydrogen cooling [today] In 1993 Siemens put the first 170MVA air-cooled generator optimized by computer simulations of the flow-fields and since then hydrogen cooling has been confined to an ever-decreasing top tier of name-plate power.
Certainly there are other ways, and hydrogen cooling may have decreased in popularity in the decades since I was paying attention (I consulted for a turbine generator manufacturer in the late '80s). But there are lots of hydrogen-cooled alternators in service, and it appears that they are still being built.
