Because H2 can be made at a wide range of scales (from household to large city) and from a variety of primary sources (fossil, renewable and nuclear), there are many possible pathways for producing and distributing H2 to users. The DOE has identified the need to find viable transition strategies toward widespread use of H2.</p><p>In this work, we developed and applied simulation tools to evaluate alternative pathways toward widespread use of H2 under various demand scenarios and regional conditions. Geographic information system (GIS) data are utilized as input to analysis, and to visualize results. The use of mathematical programming or other methods to screen the large design space of possible transition pathways for optimum solutions is employed. Using these techniques we... https://escholarship.org/uc/item/03w4z6qs Thu, 9 Sep 2010 00:00:00 +0000 Ogden, Joan M Johnson, Nils Yang, Christopher Ni, Jason Lin, Zhenhong Johnson, Joshua https://escholarship.org/uc/item/39b7x7cw <p>Presented to the Hydrogen and Fuel Cell Caucus, Washington, DC, January 11, 2005</p> https://escholarship.org/uc/item/39b7x7cw Mon, 16 Aug 2010 00:00:00 +0000 Ogden, Joan M
