Rising gas prices – said to soon hit $4/gallon here in the U.S. – have people talking again about biofuels and biodiesel. The idea of growing our own gas is generally thought to be a good alternative, until people start worrying about the impact of taking corn, soybeans and other crops that would otherwise be used for food and putting them into our gas tanks.
But wait a minute! Is algae the future of biofuels instead?
There are many positive attributes of the green seaweed organisms, including the fact that it is much cheaper to harvest than traditional crops. In fact, researchers at the Rochester Institute of Technology believe that algae is the “wave of the future” when it comes to biodiesel!
When algae is used as a source of fuel, it can replace the use of diesel by 50%. The green organisms can be turned into green fuel using technology developed by Environmental Energy Technologies, which use a single-cell algae to make biodiesel. The team is currently (forgive the pun) pumping out a new batch of algae each week to create 100 gallons that can be turned into biofuel.
Their algae production is set to be increased 10-fold by this spring, further underscoring the efficient, cost-effective superiority of algae over corn or soybean production.
I’m all for the green fuel. What do you think about using algae as biodiesel?
