This paper introduces a method to assess the reliability of hydrogen supply systems for transportation applications. It relies on a panel of experts to rate the reliability and importance of various metrics as they pertain to selected hydrogen systems. These are aggregated to develop broad...

Reliability has always been a concern in the energy sector, but concerns are escalating as energy demand increases and the political stability of many energy supply regions becomes more questionable. But how does one define and measure reliability? We introduce a method to assess reliability in...

Concerns regarding air pollution, energy dependence, and, increasingly, climate change continue to motivate the search for new transportation solutions. Much of the focus is on light-duty vehicles, as they account for approximately 60% of transportation energy use and greenhouse gas (GHG)...

Proceeding of the National Hydrogen Association (NHA) Annual Conference, Long Beach, California, March 2006.

Prepared for the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 Although reliability has not been evaluated for hydrogen energy systems, it is often assessed in other energy sectors. We investigated methods used to assess reliability...

This report describes five alternative scenarios for future energy demands in California, developed at UC Davis as part of the Advanced Energy Pathways (AEP) project. The Advanced Energy Pathways is a project of the California Energy Commission’s (CEC) Public Interest Energy Research...

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...

This paper investigates how California may reduce transportation greenhouse gas emissions 80% below 1990 levels by 2050 (i.e., 80in50). A Kaya framework that decomposes greenhouse gas emissions into the product of population, transport intensity, energy intensity, and carbon intensity is used to...
