  1. Chapter 15 The US can cut CO2 emissions but 80% by 2050, and Carbon Capture and Sequestration Can Help Achieve That Goal -Presentation by Martha Krebsbach

  2. Carbon Dioxide Emissions • In 2009, President Obama promised to reduce carbon dioxide emissions by 80% by 2050 • Suggestions have included • Transitioning to carbon-free energy • Shutting down coal plants • Where does the replacement energy come from? • Would have to replace 200 barrels of oil each day • Too many people living in energy ‘poverty’ to viably replace

  3. Under the target set by Obama • United States would have to produce less carbon dioxide now than China per capita, around 4.27 tons of CO2 a year • There is no cheap, viable alternative methods of producing that much clean energy

  4. Carbon Capture and Sequestration • “Holy Grail” of carbon strategies • Capture CO2 from the flue of coal plants • Condense it and inject it into geological formations • However, it is not economically viable • Only shown to work on small scale projects, not the large ones we need • Introduces a parasitic load of 28% on power plants, energy that is not sold to the customer

  5. Questions • What is the percent of parasitic load that would be placed on a power plant operating Carbon Capture and Sequestration? • 28% • The nation’s goals of reaching an 80% reduction in CO2 emissions is unrealistic for what main reason? • No cheap alternative to produce energy
