Widescale Biodiesel Production from Algae By Michael Briggs, University of New Hampshire, Physics Department As more evidence comes out daily of the ties between the leaders of petroleum producing countries and terrorists not to mention the human rights abuses in their own countriesthe incentive for finding an alternative to petroleum rises higher and higher.
The environmental problems of petroleum have finally been surpassed by the strategic weakness of being dependent on a fuel that can only be purchased from tyrants.
Clearly, developing alternatives to oil should be one of our nation's highest priorities. In the United States, oil is primarily used for transportation - roughly two-thirds of all oil use, in fact.
So, developing an alternative means of powering our cars, trucks, and buses would go a long way towards weaning us, and the world, off of oil.
While the so-called "hydrogen economy" receives a lot of attention in the media, there are several very serious problems with using hydrogen as an automotive fuel.
For automobiles, the best alternative at Research paper algae biodiesel is clearly biodiesel, a fuel that can be used in existing diesel engines with no changes, and is made from vegetable oils or animal fats rather than petroleum. In this paper, I will first examine the possibilities of producing biodiesel on the scale necessary to replace all petroleum transportation fuels in the U.
Then we will take a closer look at Michael Briggs' numbers and combine his proposal with the concepts presented in Water For Algae Farms. Because this web site is intended for an American audience, the examples that follow are presented in feet and acres, in place of the metric system values, meters and hectares, which Michael Briggs uses in his paper.
You do not need to be an engineer or mathematician to understand the following examples.
First, consider if you will, a treaty between the United States and Mexico, where Mexico grants the U. For the sake of discussion, let us assume that a canal has already been built between the Gulf of California and the Salton Sea; and that the Salton Sea will serve as a transfer reservoir.
Now, visualize a large aqueduct between the Salton Sea and Death Valley where a second inland sea has formed, approximately the size of the Salton Sea. From these two inland seas, several aqueducts extend out into the deserts of the Southwestern United States; Reaching into Arizona and Nevada.
Of the many and various desert farms, ranches and communities served by the aqueducts, there will be forty-thousand algae farms, having a total water surface area of acres each.
Two-hundred and fifty acres multiplied by forty-thousand farms equals a total of ten million acres of shallow water algae ponds, dedicated for the purpose of growing non-food renewable biomass for the production of transportation fuels.
Each farm would have many ponds. Here is a picture of what a single pond might look like: The pond would be shallow and the water would flow around the circle, making it easy to harvest the algae. These are salt water algae ponds.
Therefore, increasing levels of salinity caused by evaporation will be a problem. However, the problem can be solved by diluting the ponds with fresh water produced from desalinated seawater. Whenever new seawater, taken from the aqueduct, is added to the pond, desalinated seawater can be added too.
Solar energy can power the desalination equipment. A new industry would develop to capitalize on the salt and minerals extracted from the process of desalination.Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils.
Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. Several companies and government agencies are funding efforts to reduce capital and operating costs and make algae fuel production commercially viable. NOTICE: Experience with open pond algae production has shown significant problems.
Although the final stage of algae oil production—converting the lipids into biodiesel—is a proven cost effective process, growing the microalgae lipids in open ponds is not so easy. The research on biodiesel fuel at present on the production of algae to harvest oil for biodiesel has not yet been undertaken on a commercial scale.
Alga culture, unlike the crop-based biofuels does not threaten a decrease in food production, as it requires neither farmland nor fresh water.
Biodiesel can also be used as a heating fuel in domestic and commercial boilers, a mix of heating oil and biofuel which is standardized and taxed slightly differently from diesel fuel used for transportation.
Bioheat fuel is a proprietary blend of biodiesel and traditional heating oil. This sample environmental science research paper explores the importance and significance of biodiesel production methods that will enhance ecological security.
Alternative fuels and renewable sources of energy are the future of the energy market, and this paper goes into serious depth regarding the ways in which ecological security can be obtained.5/5(2). Kudzu (Pueraria lobata) was introduced to the United States twenty-five years before the turn of the twentieth century, and is currently found naturalized throughout the southeastern states years later.
