Introduction
The transportation of goods and people has dramatically altered earth’s landscape. The ease of mobility has enhanced and increased the transportation of everything. From miles traveled for our food before it arrives on our plates to the miles we travel to and from our jobs, transportation needs have increased. Humankind's insatiable appetite for transport necessitates cheap and abundant energy; a fleeting reality. Further, transportation and the energy used to power mobility has not bode well for the planet.
The transportation of goods and people will have a lasting impact on the planet. The scientific community agrees that burning fossil fuels — and thus the emittance of carbon dioxide and other effective greenhouse gasses (GHGs) — is what causes climate change. The energy used for transportation accounts for a large portion of all GHG emissions. Fossil fuels have begun to show signs of scarcity. There are becoming more expensive and difficult to retrieve (Dixon, 2013). Many have redirected their focus to renewables and other more environmentally sound alternatives. Some alternatives can even work within our current infrastructure. Further, many alternatives have proven to provide environmental mitigation such as carbon sequestration. Increasingly, scientists are looking at algae to carry out both.
Oilgae
Fossil fuels like oil and coal dominate the world’s energy portfolio. Biofuels only account for 10% of energy consumed (Dixon, 2013). Biofuel consumption is expected to expand as non-renewables are abandoned as environmental superior and more affordable alternatives manifest.
Oilgae are species of algae that contain between 30% and 75% oil when dried out (Singh, Ahluwalia, 2013). The lipid content, or rather, o...
