Peel Power: Citrus Power LLC and FPL Strike Ethanol Pact

You remember Mr. Fusion, right? At the end of the first Back to the Future movie, Doc Brown re-appears and takes Marty McFly to the future. Before they can leave, however, he has to fuel up the modified DeLorean by dropping a banana peel into the Mr Fusion he's installed on the car. Presumably, the organic matter in the peel provides the energy required for time travel (1.21 gigawatts if memory serves).

Well, apparently the folks at Citrus Power, LLC are fans of the trilogy. Or at least a derivative of it.

As the name would imply, Florida-based Citrus Power is focusing on using discarded citrus peel as the feedstock for ethanol conversion. On the surface it makes wonderful sense. In 2006, Florida produced 287 million boxes of citrus. The juicing process produced approximately 5 million tons of wet waste and 1.25 million tons of dry waste. This would put potential production at around 120 million gallons of ethanol per year.

The state of Florida, anxious to create new industrial segment based on the region's biggest crop, recently provided Citrus Power with a $2.5 million grant through the state's Department of Energy. ( The federal DoE has also funded research in the area, providing $134,000 to Renewable Spirits to build out their citrus-to-fuel technology.)

Citrus Power also has a true believer, apparently, in FPL Energy, a subsidiary of FPL Group (NYSE:FPL). FPL recently signed a letter of intent with Citrus to develop a commercial scale citrus peel-to-ethanol plant. They are targeting an output of 4 million gallons of fuel.

I love the idea of closed loop systems: the Tyson-Syntroleum partnership I wrote about here is another example. I love non-food source systems as well, as you avoid the ethical dilemma of re-routing food to fuel.

Citrus Power, however, leaves me wanting. Management team bios are long on generalities and short on detailed experience. The founder is a former computer engineer who previously worked at Renewable Spirits (which led to a recently resolved lawsuit). They are 5 employees.

So in terms of long term strategy, the best bet would seem to be holding on until a larger player comes along to purchase Citrus Power as part of an industry consolidation play. Otherwise, potential investors may want to head back to the future to recoup their investments.
