The University of Texas at Austin has assembled a large multidisciplinary team focused on developing a complete process for cost-effective algae biofuel production. The team is optimizing all steps of the process from strain selection and growth to harvesting, lipid extraction, and tracking lipids throughout processing. UT has developed several patented technologies for algal lysis and extraction and is working to drive down costs through innovation, partnerships, and scale-up strategies with the goal of commercialization. Significant challenges remain around production costs, but if successful algae biofuel production could potentially replace gasoline usage while capturing carbon dioxide.
Recent talks on biofuels have outlined their un-sustainability in the production phase; commodities such as corn, rapeseed, palm oil and soya are being grown and harvested in a way that could have negative economic, social and environmental effects, and have a global impact on land use, food security, water resources, deforestation and global markets.

In this world of concerns regarding depletion of fossil fuels, pollution control and other factors leading to threat of man kind survival a way of producing biodiesel from algae which can be a source of alternative fuel. Lots of methods and sources being used for producing biodiesel but from algae one can produce high amount of biodiesel depending on the type of species or strain selected and this way this is a viable and feasible method to produce biodiesel.....

Flue gas mitigation technology that will aid in alleviating our emissions from point sources (i.e. power plants) by supplementing growth of ALGAE to produces our transportation sector fuels.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to examine the increasing economic feasibility of algae biofuels. Algae can be grown in places where traditional crops cannot be grown and it consumes carbon dioxide, thus making it better than traditional sources of biofuels. It can also be harvested every 10 days thus making its oil yield per acre 200 times higher than corn and 40 times higher than sunflowers. The problem is that harvesting and extracting the algae requires large amounts of labor and energy (drying) and the algae may damage surrounding eco-systems. Thus new and better processes along with large scale production are needed to solve these problems. These slides discuss the various approaches (open pond, photo-bioreactor, fermentation), their advantages and disadvantages, their existing and future costs, and other improvements that are driving steadily falling costs. In the short term, algae will continue to be used in niche applications such as cosmetics, food, and fertilizers. In the long run, as the cost reductions continue, algae might become a major source of fuel for transportation and other applications.

60. UT synergizes its R&D with cost-effective scale-up strategies
61. UT is developing partnerships with other start-ups to maximize strengths
62. UT is innovative – several technology patents and patents pendingAt present most companies in the sector are early stage start-ups and involved in R&D rather than commercialization. To date, none has launched full commercialization/industrialization of biodiesel from algae oil on a large scale.
71. algae biofuel contains no sulphur, is non-toxic, and is highly biodegradable
72. algae consume carbon dioxide as they grow, so they could be used to capture CO2 from power stations and other industrial plant that would otherwise go into the atmosphere. According to U.S. Department of Energy: Currently most research into efficient algal oil production is being done in the private sector, but if predictions from small scale production experiments bear out then using algae to produce biodiesel may be the only viable method by which to produce enough automotive fuel to replace current world gasoline usage.
