In recent years, hydrogen, which does not emit carbon dioxide (CO2) as an alternative fuel to fossil fuels, has been attracting attention. However, its use as burner fuel has raised concerns due to its high maximum flame temperature and fast combustion rate, which can lead to increased emissions of harmful nitrogen oxides (NOx) and safety issues. The hydrogen burner developed in collaboration with Toyota Motor Corporation utilizes a burner structure that takes advantage of hydrogen fuel's characteristics, achieving zero carbon dioxide emissions, as well as excellent low NOx performance and high safety.
