Unit 8.1 Notes o Alternative Energy Sources o Help the Environment by reducing dependence on fossil fuels and greenhouse gases o Combustion Reactions: o Carbon (Coal) o Methane (Natural Gas) o Octane (Gasoline) o Coal is the least efficient fossil fuel o All release CO2 , which is responsible for global warming o Methane and Octane give out side products SO2 and NOx o Fossil Fuels pollute the environment and will eventually run out. o What are the alternatives? o Clean Energy Research o Zero-emission coal-fired power plants o Hydrogen (H2): non fossil fuel (not from the ground) Can hydrogen be used as a fuel? YES! Hydrogen is the most abundant element in the universe. Unfortunately, H2 is very reactive and is usually found combined with other elements. Need to separate which requires a lot of energy Example of how reactive it is the challenger and the Hindenburg accident, hydrogen is very unsafe o How can we obtain H2? o Electrolysis of water: passing a direct current of electricity of sufficient energy to break O-H bonds in water. “Breaking” water with electric current. Therefore invest same energy that you will get out of it with not much gain. o
