Hydrogen Supply: Pathways and Strategies

2005

Abstract

Presented to the Hydrogen and Fuel Cell Caucus, Washington, DC, January 11, 2005

Hydrogen Supply: Pathways and Strategies
H2 SUPPLY PATHWAYS\x0BLike electricity, hydrogen is an energy carrier produced from primary energy resources
LONG-TERM VISIONS OF H2 SUPPLY AND CHALLENGES
FULL FUEL CYCLE \x0BGREENHOUSE GAS EMISSIONS \x0B(Normalized to Adv. Lightweight 46 mpg Gasoline ICEV)\x0B
DEBATE ABOUT H2 SUPPLY: I\x0B(greenhouse gas emissions)
DEBATE ABOUT H2 SUPPLY: II\x0B(carbon “efficiency”)\x0B
DEBATE ABOUT H2 SUPPLY: III (Primary Supply)
WHERE WILL H2 COME FROM?
HOW MUCH WILL IT COST?
OPTIMIZED PIPELINE NETWORK IF 10% OF VEHICLES = H2 FCVS
DELIVERED H2 COST \x0Bv. H2 VEHICLE FRACTION
DEBATE ABOUT H2 SUPPLY: IV\x0B(Cost)
Ave. Travel Time to Nearest Station \x0BH2 at 1% of gasoline sta. => 10 minutes; 3% => 5 minutes
HOW SOON COULD H2 MAKE A MAJOR DIFFERENCE?
ACTIONS TO ENABLE A H2 ECONOMY
