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...

This paper concerns the economic and environmental challenges confronting California and the potential role for clean energy systems and hydrogen as an energy carrier in helping to address these challenges. Hydrogen in particular has recently gained great attention as part of a set of solutions...

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...

Station availability is a major concern when the deployment of an alternative fuel such as hydrogen is considered. Too few stations will make the network inconvenient, while too many will make the refueling network cost prohibitive. As a follow-up analysis to two station siting analyses...
