Abstract
A variety of proposals are in place to
utilize hydrogen (H2) as a green energy carrier which can be transported in pipelines and burned by a variety of
stationary and mobile sources, such as power plants, heaters, and trucks. As a carbon-free fuel, hydrogen has the
desirable property that its combustion releases no CO2. However, H2 combustion does generate NOx since, as noted
above, NOx is formed when air is heated to high temperatures. This white paper shows that many studies could be interpreting their NOx emissions incorrectly by as much as 40% against high-hydrogen
systems.
