Independent study confirms cost savings & emissions advantages for heavy-duty trucks running ClearFlame’s engine technology

Green Car Congress

The inherently lower soot forming propensity of ethanol compared to diesel fuel would allow ClearFlame to operate the engine closer to stoichiometric conditions, enabling the use of three-way catalyst (TWC) aftertreatment systems to control NO x emissions. per mile, lower than natural gas by $0.09

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Source of data: US EPA (2019). The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019.

The EPA last week announced stricter emissions standards for heavy-duty commercial vehicles, such as trucks and buses, for model years 2027 to 2032. Like the new emissions standards for passenger cars recently confirmed, these rules do not mandate EVs, but do set much tougher emissions targets that will likely lead to more EV sales.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.
