Summary of each fuel – and their strength and weakness
Natural Gas Fuel (- NONRENEWABLE)
1. Propane – Uses LPG
2. CNG – Burns methane
Propane engines last twice as long as conventional engines – lower maintenance.
Range is 25% less than gasoline cars because of the lower energy content of fuel
Performance is similar to a gasoline-powered car Natural gas fuels emit 1/3rd fewer reactive organic gases.
HYDROGEN FUEL
Hydrogen internal combustion engine (HFCE) produces nitrous oxides. Hydrogen fuel cell vehicle (HICEV) vehicle are used which is form of Electrochemical cell which produces electricity from hydrogen and water is a byproduct; BENEFITS
Zero emission vehicle
Greenhouse gases are 95% water vapor, natural contributor to …show more content…
Ex. Honda Insight
RESOURCE CONSTRAINT: RARE EARTH ELEMENTS
Toyota Prius is the largest user of REE’s . It uses 2.2 lbs of neodymium for electric motor and 22-32 lbs of lanthanum for NiMH battery.
China controls 95% of REEs and has been reducing exports every year since 2004 plans to stop exports by 2020.
ELECTRIC VEHICLES
Can be reality and move beyond concept vehicles if the automobiles manufactures avoid use of REE by using AC motor (Tesla did it) and lithium ion battery (GM is doing it).Lithium ion battery has twice the capacity of NiMH in half the weight (Chevy VOLT and Tesla ROADSTAR) and emits zero emissions while in use .
ELECTRIC CAPACITY- will have to develop and source renewable source of electricity to support such large scale electrification of cars and automobile industry as whole, redefining the future of mobility.
Two type of EV’s
1. EXTENDED RANGE ELECTRIC VEHICLES (EREV) –It runs on batteries, but uses an ICE to power a generator to charge the batteries when the batteries are low. Its engine can be ICE on biofuel, or fuel cell.
2. PLUG-IN HYBRID VEHICLES (PHEV) - The car is essentially an electric vehicle with a gas-tank backup.
