Brown Beer but Green Energy
May 3, 2007

For all you beer fans out there, here’s another reason to raise your glass. According to AP, Australian beer maker, Foster’s is participating in an experimental fuel cell effort to generate clean energy by using (get this) brewery waste water! Using sugar-consuming bacteria, scientists are attempting to capture chemical energy released by the bacteria and turning it into electric energy and clean water. This fuel cell will be installed in a Foster’s brewery near Brisbane. Scientists involved in the experiment say that “Brewery waste water is a particularly good source because it is very biodegradable… and is highly concentrated, which does help in improving the performance of the cell.” Scientists estimate that the 660 gallon fuel cell (basically a really big battery) can produce 2 kilowatts of power, or enough power for one household consumption. An innovative way to treat waste water and make some energy in the process.
Cheers!
