Go / No-go Decisions & Independent<br />
Assessments<br />
“Go / No-go” decisions are used in downselecting certain research pathways to focus on the most<br />
promising areas. They are defined by performance-based technical milestones <strong>and</strong> quantitative<br />
metrics. Expert Panels are convened for independent assessments.<br />
A “no-go” decision<br />
• May indicate that further advances in basic science are needed<br />
• May eliminate an entire technology pathway<br />
Key examples<br />
• Single-walled Carbon Nanotubes — “no-go”<br />
• Thermochemical <strong>Hydrogen</strong> Production — three cycles selected out of 350<br />
• Sodium Borohydride for On-Board Vehicular <strong>Hydrogen</strong> Storage — “no-go”<br />
• On-board <strong>Fuel</strong> Processing — “no-go”<br />
The decision tree used by the<br />
Program in the process of downselecting<br />
pure carbon single-walled<br />
nanotubes (SWNTs) for hydrogen<br />
storage.<br />
As a result of the first no-go decision<br />
shown on the left side of the figure,<br />
funding was redirected to the areas<br />
shown on the right side of the figure.<br />
