Today it was announced by NRG Energy that GreenFuel Technologies began field testing of their algae bioreactor system that recycles carbon dioxide emissions from the coal burning Big Cajun II Power Plant (Louisiana) into rich biofuels.
" 'Coal is—and will remain—the premier domestic fuel source for power generation purposes in the United States for the foreseeable future,' said David Crane, NRG President and Chief Executive Officer. 'This means it is incumbent on us not only to build new coal plants using technology which limits or eliminates greenhouse gas emissions but also to find the best way to retrofit the country’s existing fleet of coal plants for post-combustion carbon capture.'
In the initial field testing, which will last approximately four months, algae species will be selected to optimize biofuel production based on the site’s flue gas composition, local climate and geography toward an ultimate goal of construction of a commercial-scale facility.
A full scale commercial deployment could recycle enough CO2 to yield as much as 8,000 gallons of biodiesel per acre annually under optimum conditions.
'We at NRG and Big Cajun are very proud of our environmental record and want to do more to support responsible baseload electricity generation,' said Jeff Baudier, President of NRG’s South Central Region. 'There is currently no commercial-scale technology to address the discharge of carbon post combustion. Through this test, we hope to help advance GreenFuel’s technology that could potentially reduce carbon emissions from the hundreds of existing coal plants that are so important to our electrical infrastructure.'
'With the help of forward thinking and environmentally responsible companies like NRG, we can use algae to recycle power plant CO2 emissions safely and economically into a continuous supply of clean, renewable fuels,' said GreenFuel Technologies CEO, Cary Bullock. "
