Low level of dependence on other countries. You can also use the CO2 from the distilleries for the production of algae (which in turn can be used to produce biofuels). Algae biofuels may provide a viable alternative to fossil fuels; however, this technology must overcome a number of hurdles before it can compete in the fuel market and be broadly deployed. It uses large volumes of carbon dioxide. In brief, first generation biofuels: substrates used are food based crops, grains, seed, vegetable oils, animal fats, or sugar, to produce bioalcohols (such as ethanol, butanol), biodiesel .
. Its overhead cost is high. Algae store energy in the form of oils and carbohydrates, which, combined with their high productivity, means they can produce from 2,000 to as many as 5,000 gallons of biofuels per acre per year. A variety of photoautotrophic-based microalgal culture systems are available. It is very difficult to transport large quantities of electricity without using heavy, relatively inefficient batteries.
