Energy Economics
In "Gassing Up with Hydrogen,” Sunita Satyapal, John Petrovic and George Thomas write about the difficulties of storing hydrogen in automobiles to create a replacement for today’s internal-combustion engines. Given the technical and economic challenges the authors describe, the targets they list for storage quantity and costs for 2010 and 2015 seem optimistic. But even if those targets are met, then what? For automobiles running on hydrogen fuel to replenish their supplies, several thousand fueling stations would have to be built at the cost of billions of dollars. Further, a new delivery infrastructure would have to be created to get hydrogen (or hydrogen precursors) to those stations.
