DOE Issues Statement on Hydrogen Storage Research

December 12, 2006

The DOE Hydrogen Program has decided to only discontinue (a "no-go" decision) future applied R&D investment in pure, undoped, single walled carbon nanotubes for vehicular hydrogen storage applications. However, certain areas of carbon nanotube research, such as metal-doped hybrid materials, may warrant additional R&D investment. View the "full discussion document" (PDF 176 KB) for details.
