OUTLINE QUEST FOR FUTURE FUELS TYPES OF FUTURE FUELS FUELS HOW THEY ARE PREPARED USES CONCLUSIONS REFERENCES
QUEST FOR FUTURE FUELS Fuel resources that our planet hold is exhaustible and will end in the coming future Rapid industrialization and massive growth in population has increased the dependence and use of natural fuels Approximately 90% of our energy requirement are met by fossil fuels This increase in energy consumption particularly in the past several decades has raised fears of exhausting vital natural resources So this has placed a need for us to engage ourselves in search of fuels which would support us in the future when no fossil fuels are present
TYPES OF FUTURE FUELS BIODIESEL Derived from Soy bean , sunflowers, corn, olive, peanut, palm, coconut and animal fats Has same vehicular performance as Diesel Economical fuel source It is sulfur free Completely renewable fuel source
HOW IS IT PRODUCED chemically reacting lipids (e.g., vegetable oil, animal fat )with an alcohol producing fatty acid esters which is biodiesel USES Mixed with diesel to reduce pollution Can be directly used in vehicles
HYDROGEN It is an emission less fuel By-product of hydrogen burning is water Stores up to 3x as much energy as conventional natural gas If used in a car, it would take comparatively less to fill it up than a car running on standard fuel due to the hydrogen fuel cell efficiency
WAYS TO PRODUCE HYDROGEN hydrogen is usually produced by the steam reforming of methane or natural gas CH 4 + H 2 O → CO + 3 H 2 + 191.7 kJ/mol Partial oxidation of sub stoichiometric fuel-air mixture in a reformer , creating a hydrogen-rich syngas C 12 H 24 + 6 O 2 → 12 CO + 12 H 2 H 2 is also produced by Coal Gasification yielding syngas
USES H 2 is widely used in fuel cells for electricity generation and vehicle propulsion Widely used for Rocket Engines
ALCOHOL FUELS T hey are convenient fuels for storing and transporting energy Is a renewable energy source Can be produced from a variety of feedstock such as sugar cane, potatoes, sweet potatoes, molasses, corn, etc. Is a particulate-free burning fuel source
HOW IS IT PRODUCED M ethanol is produced from natural gas, although it can be produced from biomass using very similar chemical processes Ethanol is commonly produced from biological material through fermentation processes C 6 H 12 O 6 → 2 C 2 H 5 OH + 2 CO 2 USES Most commonly used to power automobiles Additive for gasoline
NUCLEAR REACTORS Nuclear power is a nuclear technology designed to extract usable energy from atomic nuclei via controlled nuclear reactions Nuclear power is usually used by using a nuclear reactor to heat a working fluid such as water, which is then used to create steam pressure, which is converted into mechanical work for the purpose of generating electricity or propulsion in water It is completely a pollution free source, however spent nuclear fuel poses a threat
HOW IS NUCLEAR FUEL PRODUCED To prepare uranium for use in a nuclear reactor, it undergoes the steps of mining and milling, conversion, enrichment and fuel fabrication
USES It is most widely used for electricity generation TOPAZ nuclear reactor are built to minimize moving parts and use methods that convert nuclear energy to electricity directly making them useful for space missions Naval vessels making use nuclear powered engines have come into existence Nuclear powered crafts are under development
RADIOTHERMAL GENERATORS Radio Thermal G enerators produce electricity from the decay of a radioisotope Radioisotopes have been used as alternative fuels, on both land and in space The decay of radioisotopes generates both heat and electricity in many space probes, particularly probes to outer planets where sunlight is weak, and low temperatures is a problem
CONCLUSIONS The future fuel sources are environment-friendly as opposed to fossil fuels Throughout the year these sources are available without affecting the Environment Using these fuels helps diminish Global Warming Helps conserve natural resources
