India gets into race of Bio diesel

Minister of Science & Technology and Earth Sciences Shri Vilasrao Deshmukh would flag off the first test-run of a fully loaded TAVERA (a regular diesel vehicle) on neat (B100) “microalgal biodiesel” third generation..

Microalgae are photosynthetic microorganisms which convert sunlight, water and CO2 to sugars, from which macromolecules, such as lipids and triacylglycerols (TAGs) can be obtained. These TAGs are the promising and sustainable feedstock for biodiesel production.

Algae fuel might be an alternative to fossil fuel and uses algae as its source of natural deposits
High oil prices, competing demands between foods and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels, using land that is not suitable for agriculture. Among algal fuels' attractive characteristics: they do not affect fresh water resources,[2] can be produced using ocean and wastewater, and are biodegradable and relatively harmless to the environment if spilled.[3][4][5]
  • Algae cost more per unit mass (as of 2010, food grade algae costs ~$5000/tonne), due to high capital and operating costs,[6] yet are claimed to yield between 10 and 100 times more energy per unit area than other second-generation biofuel crops.
  • The United States Department of Energy estimates that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles (39,000 km2) which is only 0.42% of the U.S. map[9], or about half of the land area of Maine. This is less than 17 the area of corn harvested in the United States in 2000.[10]
  • Microalgae have much faster growth rates than terrestrial crops 20-30 times, algae have a harvesting cycle of 1–10 days
  • The per unit area yield of oil from algae  is 7 to 30 times greater than the next best crop, Chinese tallow
  • Algae can produce up to 300 times more oil per acre than conventional crops, such as rapeseed, palms, soybeans, or jatropha
  • Algae can also be grown on land that is not suitable for other established crops, for instance, arid land, land with excessively saline soil, and drought-stricken land. This minimizes the issue of taking away pieces of land from the cultivation of food crops
  • Blue Marble Production is a Seattle based company that is dedicated to removing alga from algae-infested water. This in turn cleans up the environment and allows this company to produce biofuel.
