Biofuels is the promising source of energy for future fuel needs. Biodiesel can be established from growing plants which naturally consists of oil namely jatropha curcas, palm oil, Soybean and algae. Bioethanol can be extracted from sugar crops like sugarcane, sugar beet, maize, corn etc by yeast fermentation. Wood products can likewise be transformed into Biofuels.
The obtained Biofuels from these products consists of both benefits and drawbacks.
Advantages of Biofuels:
Ecological Benefits: The primary expectation of utilizing the biofuel is to be carbon neutral, less of CO and Sulfur, as it is made from natural deposits, and it is sustainable and pure fuels so it is good for automobiles. It decreases the green home substantially compared to other fossil fuels.
First generation biofuels can conserve carbon emissions about 60% compared to fossil fuels whereas the 2nd generation biofuels are better than very first generation fuels. It provides carbon emission cost savings up to 80%. Recently, UK Government publication specified that biofuels can minimize emissions by 50-60%. Efficiency of the engine increases by using biodiesel as the lube.
Economical: The biofuel's rate reduces significantly if the biofuel production technology spreads worldwide. The biofuels are established locally which automatically improves the rural advancement as the technology depends primarily on manual power. The rapid increase of biofuel simultaneously increases the production of these oil crops which promotes the agricultural market. The UK federal government has revealed that it decreases the taxation for cars which are environment-friendly. Additionally, the toughness of the engine increases while utilizing these combustible fuels in engines.
Renewability and Degradable: The biofuels are made from crops which are sustainable and it is naturally degradable and safer to manage and less hazardous than fossil fuels.
Disadvantages of Biofuels:
Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will got rid of more habitats. More forests have been ruined in Asian countries for the plantation. The producing mechanism of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High preliminary investment is required for the biodiesel production.
Odour: Certain biofuel crop produces heavy smell those odours are usually undesirable and biofuels plants can not be setup near the large neighborhoods.
Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking; the need for these crops for biofuels might raise the price of these food crops. The substantial quantity of water is needed for correct yield, even for drought resistant jatropha curcas plants.
Availability: The biofuels are not readily available in surplus so the diesel engines which are modified for biodiesel use might face problems. The most automobiles are not geared up for using biofuels in the engines. Some biodiesel can not withstand frost; it gets frozen in the chillier locations. It also increases the threat of microbial growth in the engine. Only couple of gas stations offer this biofuels and it is impossible to transfer the biofuels using pipelines.
Carbon emission: Biofuels are reduces the jatropha curcas greenhouse gases emission compared to other fossil fuels. Recently, the European scientist reported that the burning of biodiesel especially corn and rapeseed produces more laughing gas.
