Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

Updated facility‐level inventory and LCIA of the public electricity grid in Ontario, Canada

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract As the composition of Ontario's electricity grid will change over time, it is important to have a comprehensive understanding of the environmental impacts of Ontario's electricity grid as it stands today. However, publicly available information on impacts of Ontario's electricity grid is available only in aggregate from government sources.
