Comparability of Nitrogen Oxides Emissions from Hydrogen and Natural Gas Combustion

In recent years, hydrogen (and its derivates such as ammonia) have widely been acknowledged as a second key energy carrier in a future decarbonized energy system. They allow for global transport and long-term storage of substantial amounts of renewable energy on an industrial scale. At the same time, hydrogen combustion can serve to decarbonize a wide variety of end-use applications such as high-temperature process heating, thermal power generation or aviation.
