Technical and Economic Assessment of Transportation Electrification in Heavy-Duty On-Road and Off-Road Applications

Research Product Type
Dissertation / Thesis
This dissertation focuses on the assessment of technical feasibility and economic workability of BEVs in a variety of heavy-duty on- and off-road applications.In the on-road HDV segment, battery electric trucks (BETs) have become commercially available in recent years, but their ability to operate at the same level as conventional diesel trucks was unclear.

The Effects of Oxidized Biodiesel Fuel on Fatty Acid Methyl Ester Composition and Particulate Matter Emissions from a Light-Duty Diesel Engine

Research Product Type
Dissertation / Thesis
In this study, PM mass generated from a light-duty diesel engine running on three different fuel types—pure (“neat”) B100 biodiesel, pure B0 diesel, and B20 (20% v/v biodiesel blend with diesel)—was quantified and compared to the PM mass (and concentrations) from repeated emissions testing using artificially oxidized B100 and B20 biodiesel as the fuel source.

Research Product Type
Dissertation / Thesis
This mixed-methods dissertation explores questions related to the governance landscape and the institutional and political factors that surround highway expansion projects.

Understanding the Role of Transportation in Meeting California’s Greenhouse Gas Emissions Reduction Target: A Focus on Technology Forcing Policies, Interactions with the Electric Sector and Mitigation Costs

Research Product Type
Dissertation / Thesis
The overarching goal of this dissertation is to learn about the future options and policies for a low carbon energy system and transportation sector. It consists of three chapters build upon and extend the CA-TIMES framework, and address three key issues in energy/economic modeling.
