Reducing greenhouse gas emissions in the transport sector is known to be an important contribution to climate change mitigation. Some parts of the transport sector are particularly difficult to decarbonize; this includes the heavy-duty vehicle sector which is considered one of the “hardto-abate” sectors of the economy. Transitioning from diesel trucks to hydrogen fuel cell trucks has been identified as a potential way to decarbonize the sector. Howev Read More

Electrofuels fuels produced from electricity water and carbon or nitrogen are of interest as substitutes for fossil fuels in all energy and chemical sectors. This paper focuses on electrofuels for transportation where some can be used in existing vehicle/vessel/aircraft fleets and fueling infrastructure. The aim of this study is to review publications on electrofuels and summarize costs and environmental performance. A special case denoted as bio-electrofuels in Read More

The introduction of gaseous hydrogen (H2) into the intake air of a heavy-duty diesel engine results in H2-diesel dual-fuel (HDDF) combustion which offers a near-term pathway to reduce CO2 emissions in heavy-duty longhaul trucking. Since H2 introduction impacts oxygen availability combustion characteristics and emissions simultaneously it is imperative to appropriately optimize and control the input parameters including intake air pressure diesel injecti Read More
