Nice work from GM. But it could be Toyota or Honda that offer that first Hydrogen Fuelled vehicle test-drive... we'll see...

The author, Joan Ogden claims that "fuel-cell vehicles . . . face fewer technical hurdles . . ." (pp. 94.) Then she goes on to report:
1) Short fuel cell life - "current automotice PEM fuel cells last only about 2,000 hours" (pp. 97)
2) Cost - "handmade specialty items that cost about $1 millon apiece." (pp. 97)
3) Storing - ". . . large, high-pressure cylinders" or liquid at "-423 degrees Fahrenheit" (pp. 97)
4) Safety - ". . . a much wider range of concentrations of hydrogen is flammable . . ." (pp. 98)
5) Supply - ". . . hydrogen is obtained from the high-temperature processing of natural gas and petroleum." (pp. 99)
6) Cost - ". . . the current costs for producing hydrogen using these methods [electrolysis and biomasss gassification, RJW] are high: $6 to $10 per kilogram. " (pp. 99)
The article remains as accurate today as were the same facts and data decades ago. Meanwhile, I continue to commute daily in my hybrid electric.
