In addition, it has been shown that macroalgae (seaweeds) can be fermented by bacteria of genus Clostridia to butanol and other solvents. London: Taylor & Francis, 1997. Additionally, this company is also backed by Imperium Renewables, Blue Crest Capital Finance, and The Roda Group. [140][141][142][143] Experiments have also shown that more diverse aquatic microbial communities tend to be more stable through time than less diverse communities. [223] Sunlight can only penetrate a few inches through algal cells, making light a limiting reagent in open-pond algae farms. [196], The Department of Environmental Science at Ateneo de Manila University in the Philippines, is working on producing biofuel from a local species of algae. This program is involved in the production of renewable energies and energy efficiency. Algae is used in India for treating the sewage in open/natural oxidation ponds This reduces the Biological Oxygen Demand (BOD) of the sewage and also provides algal biomass which can be converted to fuel.[185]. Organization of the Petroleum Exporting Countries: Sporalore, P., C.Joannis-Cassan, E. Duran, and A. Isambert, "Commercial Applications of Microalgae". The International Air Transport Association (IATA) considers it to be one of the key elements to reduce the carbon footprint within the environmental impact of aviation. [69], The Algenol system which is being commercialized by BioFields in Puerto Libertad, Sonora, Mexico utilizes seawater and industrial exhaust to produce ethanol. The aim of the program has been to build a 50 000-litre cultivation pilot plant at the Ketch harbor facility. Studies have determined that replacing fossil fuels with renewable energy sources, such as biofuels, have the capability of reducing CO2 emissions by up to 80%. It seems, however, that with enough research and development from scientists and engineers, the pros will outweigh the cons. [208] As part of this program, the NRC made an announcement in May 2013 that they are partnering with Canadian Natural Resources Limited and Pond Biofuels to construct a demonstration-scale algal biorefinery near Bonnyville, Alberta. Advertisement. The study also introduced an efficient screening process. The preference for microalgae has come about due largely to their less complex structure, fast growth rates, and high oil-content (for some species). Alberta introduced a 5% ethanol and 2% renewable diesel requirement implemented April 2011. This process takes advantage of the relatively high temperature water to sustain algae growth even during winter months. Spirulina platensis (Arthrospira): Physiology, Cell-biology and Biotechnology. Aside from its carbon sequestration benefits, microalgae could also become a major new source of energy in the form of biofuel. [72] While hydrotreating is currently the most common pathway to produce fuel-like hydrocarbons via decarboxylation/decarbonylation, there is an alternative process offering a number of important advantages over hydrotreating. It also requires the use of fertilizers – and these are not necessarily good for the environment as they produce large quantities of greenhouse gases and might lead to water poisoning. The lipid, or oily part of the algae biomass can be extracted and converted into biodiesel through a process similar to that used for any other vegetable oil, or converted in a refinery into "drop-in" replacements for petroleum-based fuels. [45] In addition, a photobioreactor can be integrated into a closed loop cogeneration system much more easily than ponds or other methods. [33] Therefore, under budget pressure in 1996, the Aquatic Species Program was abandoned. This fuel has an energy density 10% less than gasoline, and greater than that of either ethanol or methanol. However, this technology is still in its infancy. [119] The test process converted between 50 and 70 percent of the algae's carbon into fuel. The food sources are plants and animal products used for consumption of human beings. Cook P.M. 1950. [214] This process requires the algae to grow in a dark fermentation vessel and be fed by carbon substrates within their growth media. Typically, about 1.8 tonnes of CO2 will be utilised per tonne of algal biomass (dry) produced, though this varies with algae species. [218] After experimenting with production of various algae fuels beginning in 2007, the company now focuses on producing what it calls "green crude" from algae in open raceway ponds. National Algal Biofuels Technology Roadmap Workshop, University of Maryland. 2.1. Conclusion Algae biofuel gives us a viable solution for our future transportation and energy needs when we work with strains that produce significant levels of oil. This water is then pumped back into their system. Could seaweed be the fuel of the future ? Nitrate was found to be the preferred source of nitrogen, in regards to amount of biomass grown. [92], Other species used include Clostridium saccharoperbutylacetonicum,[93] Sargassum, Gracilaria, Prymnesium parvum, and Euglena gracilis. Algae consume CO 2, and on a life-cycle basis have a much lower emissions profile than corn ethanol given the energy used to make fertilizer, distill the ethanol, and to farm and transport the latter. The harvesting cycle of microalgae is very short and growth rate is very high. In the case of D. salina, the lack of a cell wall could make algae biofuel production easier to pursue. The first algae-powered residential building, inaugurated in Hamburg, Germany, in 2013, is covered with algae which grows on the entire facade, and provides shade, for the comfort of its inhabitants. Moreover, high quality agricultural land is not required for microalgae biomass production. Several experimenters have found the CO2 from a smokestack works well for growing algae. This policy constitutes an amendment to the Federal property and administrative services act of 1949 and federal defense provisions in order to extend to 15 the number of years that the Department of Defense (DOD) multiyear contract may be entered into the case of the purchase of advanced biofuel.
