Hydrogen Cooled Generators Market To Make Great Impact In Near Future By 2025


Several power generators, with a capacity higher than 150 MW, use hydrogen as a cooling medium to transfer the heat generated within the winding enclosure to the cooler (heat exchanger). Hydrogen, being a heating medium, is seven times more effective than air and is 0.0714 times denser than air. As hydrogen is a low density medium, it helps reduce losses and at the same time, helps increase the thermal conductivity, which subsequently results in better cooling performance.

The use of hydrogen offers several advantages, such as uniform temperature profile, less frictional losses, less cooling time and high fuel to electricity conversion ratio, among others. Hydrogen cooled generators are highly efficient as compared to air cooled and water cooled generators. In a hydrogen cooled generator, the rotor as well as stator coils are cooled by the hydrogen gas. However, several power generators are provided with separate cooling media for each component, i.e. the rotor and the stator.

Hydrogen cooled generators are easy to design and install. Also, they are easy to operate, have lower maintenance costs and require less construction material as compared to other types of generators.
