Proceedings of the National Hydrogen Association Annual Hydrogen Conference (NHA 2006), March 12 - 16, 2006 The development of a hydrogen refueling infrastructure is a challenging proposition, especially in the transition where the number of hydrogen vehicles is low. These challenges include the...

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...

Presented at the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 Understanding the evolution of a hydrogen fuel delivery infrastructure depends on the spatial characteristics of the hydrogen demand. We have developed a GIS-based...

In this final report, we present results from research conducted under Phase I of NREL contract number XCM-4-44000-01, from May 2004-January 2005. The overall goal of this project is to better understand infrastructure development strategies for widespread implementation of hydrogen as an energy...

The current lack of an extensive (H2) infrastructure is often cited as a serious barrier to the introduction of H2 as an energy carrier, and to the commercialization of technologies such as H2 vehicles. Because H2 can be made at a wide range of scales (from household to large city) and from a...

Proceedings of the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 Hydrogen offers a wide range of future environmental and social benefits, when used as a fuel for applications such as light duty vehicles and stationary power. These...

Hydrogen delivery is a critical contributor to the cost, energy use and emissions associated with hydrogen pathways involving central plant production. The choice of the lowest-cost delivery mode (compressed gas trucks, cryogenic liquid trucks or gas pipelines) will depend upon specific...

As part of the H2A effort, we are developing models of hydrogen delivery systems, for use of hydrogen as a vehicle fuel. The delivery system is defined as all the equipment between the hydrogen production plant and the hydrogen refueling station. This includes hydrogen compression or...

The history of alternative transportation fuels is largely a history of failures. Niche fuels such as liquefied petroleum gases (LPG) and compressed natural gas (CNG) have persisted here and there over the years, but never captured significant market penetration for a sustained period. The two...
