Charles Lhuillier currently investigates the potential of ammonia (NH3) as a carbon-free and sustainable energy and hydrogen carrier. His experimental work focuses on the fundamental combustion properties of ammonia, as well as its combustion behavior as a Spark-Ignition (SI) engine fuel. Besides providing useful understanding for practical ammonia-fueled systems implementation, the collected data will allow Charles to evaluate the economic and environmental costs of ammonia as a SI engine fuel over its entire life cycle.
