Now algae turns crude oil in a jiffy

Out of all the clean energy options in development, it is algae-based biofuel that most closely resembles the composition of the crude oil that gets pumped out from beneath the sea bed. Much of what we know as petroleum was, after all, formed from these very microorganisms, through a natural heat-facilitated conversion that played out over the course of millions of years.

Now, researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory in Richland, Washington, have discovered a way to not only replicate, but speed up this “cooking” process to the point where a small mixture of algae and water can be turned into a kind of crude oil in less than an hour. Besides being readily able to be refined into burnable gases like jet fuel, gasoline or diesel, the proprietary technology also generates, as a byproduct, chemical elements and minerals that can be used to produce electricity, natural gas and even fertilizer to, perhaps, grow even more algae. It could also help usher in algae as a viable alternative; an analysis has shown that implementing this technique on a wider scale may allow companies to sell biofuel commercially for as low as two dollars a gallon.

Besides the potential for much higher yields, algae fuel is still cleaner than petroleum, as the marine plants devour carbon dioxide from the atmosphere.  Agriculturally, algae flourishes in a a wide range of habitats, from ocean territories to wastewater environment. It isn’t hazardous like nuclear fuel, and it is biodegradable, unlike solar panels and other mechanical interventions. It also doesn’t compete with food supplies and, again, is similar enough to petrol that it can be refined just the same using existing facilities.
