As directed by section 108 of the Energy Independence and Security Act of 2007 (EISA), the National Academy of Sciences is initiating a study to assess fuel economy technologies for medium and heavy-duty vehicles. According to EISA, the study is to develop a report evaluating medium-duty and heavy-duty truck fuel economy standards. Based on the language in Section 108, the committee will address the following tasks:
(1) consider appropriate approaches to measuring fuel economy for medium- and heavy-duty vehicles that would be required for setting standards. Given the diversity of vehicles and applications, consideration of classification of vehicles will likely be required in this review. In addition, the committee will likely have to work with DOT/NHTSA, EPA, and others, as appropriate, to identify a reasonable approach, which would then lay the basis for what technologies to consider for potential improved fuel economy. As part of its considerations, the committee will comment on what might be an appropriate metric for a fuel economy standard or a fuel efficiency measure (e.g., miles per gallon or ton-miles per gallon or other measures); how might an appropriate baseline be defined for estimating improvements; what kinds of test cycles would be appropriate; and what kinds of testing facilities exist, or would be needed, to evaluate fuel economy. The committee is not asked to provide a standard but to give guidance to NHTSA, who will have to follow-up the committee's report with their own proposals for what should be done.
(2) assess current and potential technologies and estimate improvements in fuel economy for medium-duty and heavy-duty trucks that might be achieved. As part of its assessment the committee will also include "work" trucks, namely, those in the 8,500 to 10,000 lb weight range. The committee will need to decide what time frame is appropriate to consider for the technology assessment. In addition, the committee should try to estimate the costs of technologies for fuel economy improvements.
(3) address how the technologies identified in Task 2 above may be used practically to improve medium-duty and heavy-duty truck fuel economy. This will likely entail a discussion by the committee of barriers, time frames, competitive pressures, and other factors that may inhibit or accelerate the adoption of technologies for improved fuel economy.;
(4) address how such technologies may be practically integrated into the medium-duty and heavy-duty truck manufacturing process. Again, the committee will likely identify barriers, timing, economics, competitive pressures, and other factors, that may inhibit or accelerate the practical implementation into the manufacturing of the various vehicles under consideration.
(5) assess how such technologies may be used to meet fuel economy standards to be prescribed under section 32902(k) of title 49, United States Code, as amended by this subtitle;
(6) discuss the pros and cons of approaches to improving the fuel efficiency of moving goods as opposed to setting vehicle fuel economy standards; and
(7) identify the potential costs and other impacts on the operation of medium-duty and heavy-duty trucks.
(8) write a report documenting its conclusions and recommendations.
The Committee will hold its first meeting on Dec. 4-5, 2008 in Washington, DC. For a copy of the meeting agenda, click here.
