For the Greater Green: Algae-Based Advanced Biofuels Bring a Clean, Affordable Solution
by Paul Woods (Algenol/Renewable Energy World) … When it comes to fuel production, climate change is a crucial issue that cannot be avoided. In the U.S., 3,600 million metric tons of CO2 are emitted from stationary sources alone, not to mention the additional output from vehicles.
A key aspect of algae biofuel production provides a viable solution to this crisis. To create this fuel, the CO2 produced by other industrial processes is captured and used as feedstock for the algae in an outdoor reactor system, resulting in ethanol through photosynthesis. As solutions to reducing and handling waste emissions are developed and discussions of carbon capture and storage increase, algae’s unique process of carbon capture and reuse provides an even more sustainable alternative.
Moreover, the algae biofuel production process helps address fresh water scarcity and drought issues by naturally converting saltwater into 1.4 gallons of fresh water for every gallon of fuel. Other biofuels, like corn ethanol, can require up to 15 gallons of fresh water to produce a single gallon of fuel.
In addition, not only does algae biofuel require less land than typical biofuels, the land it does use can be marginal – saving valuable, arable land for food growth and eliminating the link between food prices and fuel. As populations continue to grow and food supplies diminish, solutions that allow the most efficient use of our natural resources are critical.

To the surprise of many, half of American built vehicles produced in 2012 and on can run on E85 fuel. Yes, many older vehicles still exist, but as a society it’s time to think long-term. As the biofuel industry progresses, so will the production of vehicles designed to handle larger percentages of ethanol. At 8,000 gallons per acre instead of 420, with high-yield, low-cost ethanol you’ll be experiencing a different kind of sticker shock with significant savings at the pump. READ MORE
