nificant increase from the zero budget for heavy-duty hybrid R&D over the past 3 years would be required.

Recommendation 4-5. The 21CTP should establish plans and develop realistic budgets for accomplishing the six new stretch goals for heavy-duty hybrid vehicles in accordance with the committee’s findings, explain the rationale behind the new goals, and provide the current status of the applicable technology for each of the goals so that the magnitude of the tasks for each can be assessed.

RESPONSE TO RECOMMENDATIONS IN NRC PHASE 1 REPORT

The DOE concurs with the recommendations regarding hybrid powertrains made in the NRC Phase 1 report (see Recommendations 4-1 through 4-9 in NRC, 2008). In the energy storage area, the DOE recognizes that current light- duty battery work may not necessarily apply to heavy-duty applications. A DOE-sponsored meeting on energy storage, held in January 2011, provided a crosscut of light-duty/heavy-duty work (see Appendix C in this volume, presenting the 21CTP Response to Finding 4-2 and Recommendation 4-2 on hybrids). The DOE plans activities to increase codes and standards work for hybrid components. It has plans to explore additional power density needs for heavy-duty applications, and two of the SuperTruck projects include hybridization of Class 8 trucks. One recommendation (Recommendation 4-7 in NRC, 2008) addressed the structure of the partnership between the DOD, the DOT, and the DOE. Given the separate funding mechanisms of these agencies, the DOE acknowledges their central role in fostering cross- agency communications. The DOE plans to explore strategic alliances with stakeholder organizations.
