Industrial Applications
Hydrogen in Action
Across Industries
With its high energy density, hydrogen can be stored in large quantities for extended periods and converted into electricity, heat, or other forms of energy whenever needed. From manufacturing and steelmaking to ports and power generation, hydrogen is replacing fossil fuels across diverse sectors and accelerating the energy transition.
Hydrogen-Based Heat Source for Industrial Decarbonization
Hydrogen Burner
Hydrogen burners are low-emission thermal energy systems that generate heat through the combustion of hydrogen and oxygen. By replacing conventional LNG burners in automotive manufacturing processes, hydrogen burners can reduce carbon dioxide emissions. In addition, the adoption of lean-burn technology minimizes nitrogen oxide (NOx) emissions.
Hyundai Motor has completed the development and performance validation of a 100,000 kcal/h-class hydrogen burner. Together with Hyundai Rotem, the company has also jointly developed a 1,000,000 kcal/h-class hydrogen burner.

FAQ
Questions About
Industrial Applications
-
A burner is a device that generates heat by burning fuel. When a conventional LNG burner combusts fuel, it emits carbon dioxide (CO₂) and water vapor (H₂O). By contrast, a hydrogen burner emits only water vapor, making it a more environmentally friendly heating system.
Hydrogen burners can be used in a variety of facilities at automotive manufacturing plants, including paint ovens, boilers, regenerative thermal oxidizers, and air-handling units. Hyundai Motor Company began applying hydrogen burners to the paint ovens at its Ulsan plant and plans to gradually replace LNG burners at its domestic production facilities.
-
The theoretical flame temperature of hydrogen is approximately 2,100°C, which is higher than that of LNG at approximately 1,950°C. However, by adjusting the air supply, hydrogen burners can be controlled to operate at temperatures comparable to those of LNG burners. Their thermal efficiency can also be made equivalent to that of LNG burners through optimized burner design.
However, hydrogen has a higher flame propagation speed and a wider flammability range than LNG. Therefore, the use of specially designed burners and dedicated control technologies is required.
-
Hydrogen fuel cell electric port AGVs can reduce vehicle weight by approximately 1.6 metric tons compared with battery-powered models. This improves energy efficiency and reduces the load imposed on yard pavements. They can also significantly improve overall equipment utilization through shorter refueling times.
As ports transition to carbon-neutral operations, hydrogen fuel cell electric AGVs can help minimize the need for large-scale expansion of electrical infrastructure. Hydrogen is expected to be supplied efficiently through mobile hydrogen refueling facilities within the port, operated in conjunction with tube trailers.
-
A fuel cell power generator consists of a power generation module and a PCS (Power Conditioning System) module, which operate as a set. Specifically, one power generation module consists of two engine-type fuel cells and operates together with one corresponding PCS module. The PCS module is a power conversion device that converts the direct-current (DC) electricity generated by the fuel cells into alternating-current (AC) electricity.
To increase the power generation capacity, an additional power generation module must be installed together with an additional PCS module. It is not possible to operate two power generation modules with only one PCS module.
-
The fuel cell power generator operates using a direct hydrogen supply system. Hydrogen can be supplied directly through a connection to a hydrogen pipeline. If no hydrogen pipeline is available, a pipeline can be configured and connected using hydrogen cylinders.
However, when hydrogen cylinders are used, the generator’s operating time is more limited than when it is connected to a hydrogen pipeline. At an output of 100kW, the generator consumes approximately 6kg of hydrogen per hour.
-
In the conventional blast furnace process, coal, in the form of coke, is used as a reducing agent during iron production, resulting in significant carbon dioxide emissions. By contrast, low-carbon steel making, which uses hydrogen instead of coal (coke), produces clean water rather than carbon dioxide during the iron production process.
In the medium to long term, Hyundai Steel aims to develop low-carbon steel making technology powered by renewable energy and green hydrogen and seeks to reduce carbon emissions by more than 90% compared with the conventional blast furnace process and ultimately establish a carbon-neutral steel production system.
