When the Committee on Assessment of Resource Needs for Fuel Cell and Hydrogen Technologies put out its report through the National Academies of Science last month – the one that was very critical of plug-in vehicles (PHEVs) – plug-in advocate Felix Kramer issued a quick response that said, in part, that the report's "science and economics need to be refuted." He has since gone and done just that, and his lengthy response is now available on the CalCars website.

The reader's digest version of Kramer's response is that the NAS report is totally out of control when it tries to predict advanced battery costs for the next decade. Instead of a drop from over $1,000 per kilowatt hour (kWh) to maybe $400/kWh over ten years, as predicted in the report, there are hints that battery costs for plug-in vehicles that will be available in 2010 are around $600 or $500 per kWh. Also, Kramer criticizes NAS for not looking at the whole gamut of plug-in vehicle options and instead focuses solely on ones with 40 miles of all-electric range. These are just two limits that report runs into, and does put the overall criticism into question. Read all of Kramer's thoughts here. Thanks to David M. for the tip!
