Production of biofuels from biomass materials
Biofuels
Liquid or gaseous fuels primarily produced from biomass, and can be used to replace some fossil fuels
Ethanol (EtOH)
Biologic
Synthetic
Used for additive
Biodiesel or FAME (fatty acid methyl ester)
Completely ,iscible woth diesel fuel
Used as additive
Biomass to liquid(BTL) via gasification
Biofuels are examples of renewable energy sources that are not always green because they produce greenhouse gases
Objectives
Reduce waste
Cleaner air
New agricultural markets
Energy security
Energy shortage
Application
Transportation
Power generation
Heat
Generation
1st
made from sugar, starch, vegetable oil, or animal fats using conventional technology
Problem
Much debate over their actually benefit in reducing green house gas and CO2 emissions due to the fact that some biofuels can produce negative net energy gains
Releasing more carbon in their production than their feedstock’s capture in their growth
Issue
Majority of biofuels are produced directly from food crops
Blamed for the global increase in food prices
2nd
Produced from non-food crops
Life cycle assessments indicated that they will increase ‘net energy gains’ over coming another of the main limitations of 1st generation biofuels
Aimed at being more cost competitive in relation to existing fossil fuels
3rd
Produced from extracting oil of algae
manufactured into a wide range of fuels such as diesel, petrol and jet fuel
4th
Aimed at not only producing sustainable energy but also a way of capturing and storing CO2
not only captures and stores carbon dioxide from the atmosphere but it also reduces CO2 emissions by replacing fossil fuels
Method and strategies
