So What’s the Solution?
In GM’s view we must
Increase fuel efficiency of conventional propulsionvehicles in response to market demands
Displace a portion of petroleum fuel usage
Diversify energy sources for use in transportationapplications
Reduce net emissions of carbon dioxide

Advanced Battery Technology
Much improvement over time
Focused on “power” for hybrids,NOT “energy” for plug-insand pure electric vehicles
Lithium-ion chemistry canprovide both power andenergy
Greatest hurdle: Develop large, high-volume lithium-ion battery packs
Individual cells that meet requirements exist
Cost ($/kWh)
Requires intensive development with battery sources

In Brazil, FlexPower is now available inevery passenger car model.FlexPower models account for 90%of sales.
In Sweden, Saab leads theenvironment-friendly car segmentwith 9-5 BioPower, accounting for85% of Saab 9-5 sales.
In U.S., GM has 2 million FlexFuelE85-capable vehicles on theroad. Building >400,000 moreevery year.
25
Biofuels will play a key role
Achieving the maximum potential of biofuels willrequire continued innovation
Plants with high yields and low resource inputs
Low cost cellulosic conversion technologies
Improved systems for resource and fuel logistics
Propulsion technologies that maximize “Field-to-Wheels” fuel efficiency
But what about
COAL?

How will Coal be Used?
Coal to liquidsFischer Tropsch liquids compatible with oil infrastructure
Methanol and dimethyl ether lower manufacturinginvestment
China is the place to watch
ElectricityMuch progress still needed in battery cost andperformance
Hydrogen Storage technology and infrastructure
Affordable CO2 sequestration will be the key to largescale use of coal
