RWE from june 4th 20009... this is GREAT (imho):
Algae has been cultivated primarily as a source of biofuel, but Renewed World Energies (RWE) is taking it one step further. The company wants to clean up power plant and industrial plant emissions using algae and then have the algae turn the CO2 captured to generate both an oil and a cake product.
RWE will be building its first facility in Georgetown County, South Carolina. South Carolina is where RWE’s oil processing plant and algae bioreactors will be located. The company grows several different strains of algae and has a “proprietary automated harvesting technology.”
Besides growing the algae, RWE recently announced a process that captures the CO2 and nitrous oxide from smokestacks to grow algae. In essence, the company is using the pollution generated from power plants and industrial smokestacks to grow clean energy products thereby killing two birds with one stone.
RWE’s fully automated and modular photo-bioreactors are alleged by the company to be the first technology that is ready now for commercial application. The company states that its technology, unlike other algae technologies, has moved beyond the research stage and is ready to be implemented. Since the South Carolina facility is not expected to be up and running until mid to late 2010, we’ll see if the companies projections are true.
The algae reactors will produce both oil and cake products. The oil and cake products are expected to be “used in everything from pharmaceuticals, nutraceuticals and cosmetics, organic feed, organic fertilizer, and used as a feed for the aquaculture industry.”
Algae oil directly from the automated process could be used as biodiesel like vegetable oil but the diesel engine would have to be modified. Usually, the oil is “transesterified” for use in ultra-low sulfur diesel engines. RWE is also planning on providing oil for JP-8 jet fuel.
Again, since RWE’s South Carolina facility is not expected to open until 2010, we can only wait and see if the company is able to follow through on all of its plans. Hopefully RWE will not wind up being another algae company like GreenFuel that recently went belly up.
Using algae to clean up green house gases released by smokestacks and turning it into clean energy products provides a two for one return on investment making RWE’s process a better bargain for communities.
