Government policies increasingly promote ethanol and other biofuels for security, air quality, and climate benefits. One chapter of this dissertation develops a model that links the distribution of preferences for ethanol to aggregate price responses and then estimates the model using data from...

This study aims to determine the most appropriate alternative fuel technology to comply with possible different imposed emission regulations while ensuring optimal business performance. In this context, the most suitable alternative fuel technology minimizes the required freight rate while...

The transportation sector is a significant contributor to current global climatic problems, one of the most prominent problems that today's society faces. In this dissertation, three complementary problems are addressed to support emissions reduction efforts by providing tools to help reduce...

International maritime shipping is confronted from 2006 onwards with regulation until 2030 by different policy actors (i.e. International Maritime Organization, hereafter IMO), the EU) in order to improve the ecological performance of maritime shipping, and will face more so in the future. Many...

As a potential means of offsetting diesel fuel usage and reducing the environmental impact of used tyres, this study investigates the NOx emissions of a modern commercial passenger vehicle run on a blend of diesel and tyre pyrolysis oil (TPO). The test vehicle was driven on a route...

Ever-growing energy demand has motivated engine researchers to find eco-friendly and sustainable cleaner fuels for diesel engines. Many scientists have used different oxygenated additives to enhance the performance of the acetylene fuelled diesel engine, whereas no work has been found in the...

In this paper, we study the impact of fuel availability on demand for alternative-fuel vehicles, using data from a survey of some 600 potential car buyers in Germany. The survey was conducted as a computer-assisted personal interview and included a choice experiment involving cars with various...

Greenhouse gas emission reductions are at the centre of national and international efforts to mitigate climate change. In road transportation, many politically incentivised measures focus on increasing the energy efficiency of established technologies, or promoting electric or hybrid vehicles....

Recent optimistic revisions to projections for recoverable natural gas resources in the United States have generated renewed interest in the possibility of greater utilization of natural gas as a transportation fuel. Against a backdrop of significant policy challenges for the United States,...
