Table 2 Some advantages and disadvantages of biofuel production and use [56]
From: The current status, challenges and prospects of using biomass energy in Ethiopia
Aspects | Advantages | Disadvantages |
|---|---|---|
Cost | It is made from renewable resource | Currently more expensive than fossil diesel fuel |
Energy | Fossil diesel fuel is a limited resource, but biofuels can be manufactured | Mainly produced from edible oil, which could cause shortages of food supply and increased prices |
Availability | From a wide range of materials | Reduction of fuel economy |
GHG emission | Significantly less harmful carbon (CO2,CO,TCH) emission | Conflicts with food supply |
Energy security | Viability of the first-generation biofuel production relatively less flammable compared to fossil diesel significantly better lubricating properties significantly less harmful carbon emission compared to standard diesel | less suitable for use in low temperature it can only be used in diesel powered engines More likely than fossil diesel to attract moisture |
Air pollution | significant reduction of PM emissions | Caused increases in NOx |
