FreedomCAR: 2010 Technology Goals      NHA Home • NHA News Index

The following goals for FreedomCAR were disseminated at a hearing before the Science Committee of the U.S. House of Representatives on February 7, 2002. David K. Garman, Assistant Secretary for Energy Efficiency and Renewable Energy delivered this information to the Committee. His full remarks can be viewed on the Science Committee website at http://www.house.gov/science/welcome.htm.

It is important to remember that these goals may change based on the outcome of the Hydrogen Vision Roadmap Workshop and the Fuel Cell Report to Congress.

Fuel Cell Powertrains

• Electric Propulsion System with a 15-year life capable of delivering at least 55kW for 18 seconds, and 30kW continuous at a system cost of $12/kW peak.
  
• 60% peak energy-efficient, durable fuel cell power system (including hydrogen storage) that achieves a 325 W/kg power density and 220 W/L operating on hydrogen. Cost targets are at $45/kW by 2010 ($30/kW by 2015).

Hydrocarbon Fuel Platform

• Internal combustion engine powertrain systems costing $30/kW, having a peak brake engine efficiency of 45%, and that meet or exceed emission standards.
  
• Fuel cell systems, including a fuel reformer, having a peak brake engine efficiency of 45%, and that meet or exceed emissions standards with a cost target of $45/kW by 2010 and $30/kW in 2015.

Hybrid Systems

• Electric drivetrain energy storage with 15-year life at 300 Wh with discharge power of 25 kW for 18 seconds and $20/kW.

Hydrogen Transition

• Demonstrated hydrogen refueling with developed commercial codes and standards and diverse renewable and non-renewable energy sources. Targets: 70% energy efficiency well-to-pump; cost of energy from hydrogen equivalent to gasoline at market price, assumed to be $1.25 per gallon (2001 dollars).
  
• Hydrogen storage systems demonstrating an available capacity of 6 weight percent hydrogen, specific energy of 2000 W-h/kg, energy density of 1100 W-h/liter at a cost of $5/kWh.
  
• Internal combustion engine powertrain systems operating on hydrogen with a cost target of $45/kW by 2010 and $30/kW in 2015, having a peak brake engine efficiency of 45%, and that meet or exceed emission standards.

Manufacturing Base

Material and manufacturing technologies for high volume production vehicles which enable/support the simultaneous attainment of:

• 50% reduction in the weight of vehicle structure and subsystems;
  
• Affordability; and
  
• Increased use of recyclable/renewable materials. ©2002. All Rights Reserved. A Publication of the National Hydrogen Association.
