Starting from the premise that new consumer value must drive hydrogen-fuel-cell-vehicle (H2FCV) commercialization, a group of opportunities collectively called “Mobile Electricity†is characterized. Mobile Electricity (Me-) redefines H2FCVs as innovative products able to import and...

Hydrogen has been proposed as a low polluting alternative transportation fuel that could help improve urban air quality. This paper examines the potential impact of introducing a hydrogen-based transportation system on urban ambient ozone concentrations. This paper considers two scenarios, where...

Carsharing has grown considerably in North America during the past decade and has flourished within metropolitan regions across the United States and Canada. The result has been a new transportation landscape, which offers urban residents an alternative to automobility without car ownership. As...

This paper uses a structural econometric model to analyze the investment timing game in offshore petroleum production that ensues on wildcat tracts in U.S. federal lands off the Gulf of Mexico. When individual petroleum-producing firms make their exploration and development investment timing...

Past automotive trends, ongoing technology breakthroughs, and recent announcements by automakers make it clear that reducing the mass of automobiles is a critical technology objective for vehicle performance, carbon dioxide (CO2) emissions, and fuel economy. Vehicle mass-reduction technology...
