Why go to hydrogen? - Problems Limited oil supply CO2 emissions cause pollution (Smog in large cities)

Limited Oil Supply According to the United States Geological Survey's (USGS) latest report, published in 2000, with 28.8 billion barrels currently being used a year (79 million a day), there is some 80 years of supply left in the ground.

CO2 emissions from cars The average mileage per year in a petrol car is 12,000. This equates to approximately 6 tons of CO2 per year

Increase in emissions from cars During the year 2000 in the United States alone, the number of motor vehicles has increased six times faster than the number of humans and twice as fast as the number of new drivers. In California, it was found that 65% or more of air pollution since the 1940’s along the Southern coast was due to motor vehicle tailpipe emissions

Solutions

Peter Schwartz, of the Global Business Network, “by 2013, a third of all new cars sold could be hydrogen-powered, 15% of the national gas stations could pump hydrogen and the United States could get more than half of its energy from domestic sources.”

What is a Fuel Cell Engine? A fuel cell produces energy by converting hydrogen and oxygen into electricity Releases only water vapor and heat

PEM Fuel Cell

Dangers Ozone damage –The National Center for Atmospheric Research and a team of scientists from several California universities, worry that released hydrogen into the upper atmosphere could deplete the ozone layer, Soil absorption –researchers from Cal Tech like John Eiler say, “This man-made hydrogen will either be absorbed in the soil…or will react with other compounds in the atmosphere

Obstacles Restructuring of infrastructure –20-50 years to convert gas stations Public Fear –1937 German Hindenburg disaster Costs –According to Chris Birroni, GM’s leading fuel cell expert, a gas-powered engine costs only $3,000 while a hydrogen fuel-cell engine costs $30,000.

Benefits of Hydrogen Clean and efficient Economic growth Energy security Backup power supply

Benefits – oil supply If 20 % of the vehicles today used fuel cells, our world could cut oil imports by 1.5 million barrels/day.

Benefits – pollution if 10% of automobiles nationwide were powered by fuel cells, regulated air pollutants would be cut by one million tons per year and 60 million tons of the greenhouse gas carbon dioxide would be eliminated.

Action What’s being done to make hydrogen powered cars mainstream.

Bush’s 2003 State of the Union Address $1.7 billion dollar plan to help the United States become the world leader in clean hydrogen-powered automobiles.

California Clean Air Act of % of air pollution in California caused by cars Since its instatement the state has asked for alternate fuels and propulsion systems like hydrogen fuel cells.

Who is making hydrogen powered cars? –BMW –GM –Toyota –Honda –Ford –Many more to come…….

Future of Hydrogen The options are limitless
