Open Unknowns (1)

Unknown What are the most cost-effective strategies to eliminate the cold-start emission spike (responsible for ~80% of vehicle emissions per trip) for both conventional and hybrid powertrains as electrification penetrates the fleet? u-catalytic-converter-cold-start-mitigation-strategies

Active Hypotheses

Hypothesis Electrically preheating the catalytic converter to light-off temperature before engine start will eliminate >75% of total trip emissions for hybrid and plug-in hybrid vehicles where grid electricity is available, making EHC cost-effective at current carbon prices. medium
