HEV Modeling:
PDS (Portfolio Decision Support)
Background
The U.S. Department of Energy's (DOE's) Office of Energy Efficiency and Renewable Energy (EERE) sponsors research, development, demonstration, and deployment activities aimed at transforming the future of U.S. energy through improved efficiency of energy use and the development of new renewable energy resources. EERE invests in high-risk, high-value research and development that--conducted in partnership with the private sector and other government agencies--accelerates the development and facilitates the deployment of advanced energy technologies and practices.
EERE annually assesses the contribution of its work to DOE’s goals of providing affordable, clean, and reliable energy. Two energy market models are used in this assessment--one that looks in detail at the midterm (through 2030) and one that looks more generally at trends in the long term (through 2050).
Argonne's Research
PSAT was used to define the fuel economy and performance of both Fuel Cell Vehicles and Alternative Technology Light Vehicles. Given the fuel economy and powertrain component characteristics, payback analysis was used to estimate what the incremental price of vehicles would be when they become cost-competitive with conventional vehicles.
As part of the study, several hundreds vehicles were simulated, including:
- Various powertrain configurations (conventional, electric, fuel cell, fuel cell hybrid electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles)
- Various engine technologies (gasoline, diesel, hydrogen)
- Various timeframes (current, 2010, 2015, 2030, 2045)
Component and vehicle assumptions were reviewed by experts from the FreedomCAR Partnership.
