Arizona Project Uses Algae to Turn Coal Pollution Into Biofuel

Arizona Public Service, the state’s largest electricity provider, has secured $70.5 million in stimulus funds to expand an innovative project that turns carbon dioxide emissions from a coal power plant into biofuel using algae. While part of the funds will be used to scale up the algae processing portion, some of the funds will also be used to investigate the potential benefits of turning the coal into a gas prior to burning it for power.

The concept of creating two products — electricity and fuel — from the same process is known as cogeneration. In this case, the cogeneration also helps to reduce environmental pollution. It’s an idea that has been gathering support as a way to make coal less polluting while finding an additional revenue source to pay for the pollution control itself. In fact, a while back I reported on a similar pilot project in Oregon.
