Hyundai Mobis, the parts and service arm for the South Korean automakers Hyundai Motor Company, has leveraged its own hydrogen (H2) fuel cell technology for electric vehicles, to create an emergency H2 power generation system at its H2 fuel cell plant in Chungju, South Korea.

Hyundai Mobis connected five H2 fuel cell modules, typically used to form the system of the Nexo – Hyundai’s mass-produced H2 fuel cell electric vehicle – to create a power generation system with a maximum capacity of 450kW. This corresponds to about 7% of the total power consumption of the Chungju Plant and can be used as emergency power during power failures of the plant and as auxiliary power during seasonal peak times.

In addition, Hyundai Mobis has developed the parallel controller, thermal management system and uninterruptible power supply system (UPS), necessary for the power generator.

This H2 power generation system has many benefits, such as quantity control, high energy efficiency, no pollution and low noise. Because the individual components of the H2 fuel cell module are designed to be combustion-proof and the automatic H2 detection and external exhaust system are operating, there are also no safety concerns.

The biggest advantage is the ability to connect as many fuel cell modules as necessary, according to the required emergency power and auxiliary power, which varies depending on the size of the building.

Starting with the pilot operation in the Chungju Plant, Hyundai Mobis is planning to install more emergency H2 power generation systems in other production bases at home and abroad.

“The Chungju Plant emergency H2 power generation system is the first step in using the core H2 vehicle technology to produce H2,” said Vice-President Byung-ki Ahn, Head of the electrification business division of Hyundai Mobis. 

“The H2 fuel cell modules for vehicles can be used not only in power generation, but also in various other business areas like H2-powered trains or ships, drones and construction equipment,” he added.
