“loss of sealing oil for the hydrogen in the turbine”
***is H2 used for cooling, & if so, why not air, because H2 has a higher heat capacity?***
I spoke too quick. The sealing oil is to keep hydrogen in the GENERATOR part of the turbine-generator. H2 is used for cooling the generator because it creates less friction than air cooled generators. The hot H2 is then cooled by water in a heat exchanger.
The H2 must be kept at a purity of 95% or more to keep it from exploding. From all I have heard recently this may be a natural gas explosion.

thanks for that. Do you by any chance have a reference?
