Many past studies of the 'Hydrogen Economy' have presented a steady-state portrait of a mature pathway from hydrogen production and distribution through utilization. One of the key problems surrounding the hydrogen economy is the large cost of building the infrastructure. The desire to reduce...

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...

With recent economic, political, and social events worldwide, reliability in the energy sector is growing more valuable, and the surrounding issues are gaining visibility. Increasingly, concerns about energy supply security (and climate change) have led to proposals to shift away from oil...

The purpose of this report is to understand the extent to which each transportation technology could be used to help meet the 80% emissions reduction target. This report focuses on end-use demands in the transportation sector (i.e. which vehicle technologies will be used to meet demand for...

Presented at the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 The first step, in any program of self-improvement, is admitting you have a problem. My friends and colleagues, I would like to talk to you today about two big problems....

Beijing could be an attractive region to initiate a hydrogen infrastructure for transportation. Air quality is poor, oil imports are soaring, and there is a desire to introduce innovative responses for the 2008 Olympics. If Beijing were to proceed to build hydrogen infrastructure before and...
