A hydrogen-cooled turbo generator is a turbo generator with gaseous hydrogen as a coolant. Hydrogen-cooled turbo generators are designed to provide a low-drag atmosphere and cooling for single-shaft and combined-cycle applications in combination with steam turbines.[1] Because of the high thermal conductivity and other favorable properties of hydrogen gas, this is the most common type in its field today.
