A seaweed farm in Uroa, Zanzibar Algaculture in Kibbutz Ketura, Israel. Algaculture is a form of aquaculture involving the farming of species of algae. [1]The majority of algae that are intentionally cultivated fall into the category of microalgae (also referred to as phytoplankton, microphytes, or planktonic algae).
Trials of using algae as biofuel were carried out by Lufthansa and Virgin Atlantic as early as 2008, although there is little evidence that using algae is a reasonable source for jet biofuels. [60] By 2015, cultivation of fatty acid methyl esters and alkenones from the algae, Isochrysis, was under research as a possible jet biofuel feedstock. [61]
The National Algae Association (NAA) is a non-profit organization of algae researchers, algae production companies and the investment community who share the goal of commercializing algae oil as an alternative feedstock for the biofuels markets. The NAA gives its members a forum to efficiently evaluate various algae technologies for potential ...
To be competitive and independent from fluctuating support from (local) policy on the long run, biofuels should equal or beat the cost level of fossil fuels. Here, algae-based fuels hold great promise, [119] [120] directly related to the potential to produce more biomass per unit area in a year than any other form of biomass. The break-even ...
Some algae can grow faster under mixotrophic conditions rather than under photoautotrophic conditions. Under mixotrophic conditions, both light and a carbon substrate such as sugars can provide energy for cell growth. Although adding glucose increased the growth rate of the algal culture, it also adds extra cost to algal lipid production.
A range of microalgae species are produced in hatcheries and are used in a variety of ways for commercial purposes. Studies have estimated main factors in the success of a microalgae hatchery system as the dimensions of the container/bioreactor where microalgae is cultured, exposure to light/irradiation and concentration of cells within the reactor.
Iran started investigating the production of algae from 2000. Scientific evidence shows that south Iran is the richest area in the world for cultivating algae, because of high humidity, sunny weather, large unused area and salty water. [2] The first version of algae based biofuel will become available for industrial purposes in 2015. [3]
This could decrease the amount of land used to farm food for human consumption and may decrease overall feedstock. [ 18 ] While there may be problems facing the economic viability of biogasoline, the partnership between Royal Dutch Shell and Virent Energy Systems, Inc., a bioscience firm based in Madison, WI, to further research biogasoline is ...
