Disadvantages Of Algae

Since the beginning of the Industrial Revolution in 1760, global fossil fuel usage has increased from 3.8 billion tonnes of oil to 11.7 billion tonnes of oil in 2007. These fossil fuels include petroleum and coal. Many years the world has only focused on the benefits of using nonrenewable resources. These fossil fuels were in great abundance therefore it would be easy to obtain and around for many generations. They were also highly affordable and could be used to power everything from cars to planes. Also, fossil fuels brought many countries great wealth providing them with a steady income and trading bargain. The harmful disadvantages of burning these fossil fuels were overlooked. Greenhouse gas emissions caused from the burning of these products

These biofuels are mainly algae biodiesel. After years of applied research algal biofuels seem to be the most promising. Algae are attributed to a large majority of 〖CO〗_2 absorption worldwide. Algae both absorb water and Carbon Dioxide, which makes it a fundamental player in the water cycle and the carbon cycle. Macroalgae grows rapidly and in vast quantities, allowing them to be harvested from the ocean or lakes. Microalgae can be cultivated in open pond production or by using photo bioreactors. Algae can be produced into biofuel in three different ways, anaerobic digestion, tansesterification, and pyrolysis and hydrothermal liquefaction. Anaerobic digestion is the use of bacteria to degrade the organic matter of the algae without the presence of oxygen. Transesterification is where algal lipids are reacted with alcohols to produce biodiesel and glycerol (Ireland 21). Pyrolysis and hydrothermal liquefaction uses heat and pressure to turn the lipids in algae into

Since biofuel is a renewable resource, it is readily available for high demands. The demand for oil is increasing rapidly, but the availability of fossil fuels is dwindling. With Global warming being on the rise, the need to cut down on the burning of fossil fuels and release of greenhouse gases have become more evident. Algal biofuel is projected to reduce greenhouse gas emission by up to 78%. The process of making algal biofuels is also cleaner and safer for the environment. Making oil from crude form needs a lot of toxic chemicals to make it safe for vehicle usage. Algal biofuel is mainly made from the lipids and oils produced by the algae and don’t require the same harmful chemicals used in the process like in crude oil. Algal biofuels will increase fuel economy, allowing vehicles to run on higher miles per gallon. It will also lessen the need for foreign oil, providing countries means to save billions of dollars from purchasing foreign
