A benchmark dataset for Hydrogen Combustion. [PDF]

Sci Data, 2022
AbstractThe generation of reference data for deep learning models is challenging for reactive systems, and more so for combustion reactions due to the extreme conditions that create radical species and alternative spin states during the combustion process.

Electricity Powering Combustion: Hydrogen Engines [PDF]

Proceedings of the IEEE, 2012
Hydrogen is a means to chemically store energy. It can be used to buffer energy in a society increasingly relying on renewable but intermittent energy or as an energy vector for sustainable transportation. It is also attractive for its potential to power vehicles with (near-) zero tailpipe emissions.
