The corn ethanol industry doesn't need another voice to deride it's performance and unexpected consequences of late. In today's blog, I'd like to consider the lessons that we can all learn from it and some related renewable energy industries.
Much of the corn ethanol business proposition could be summed up by these facts:
1. Farmers know how to grow corn.
2. Lots of people know how to ferment and distill corn to make ethanol.
3. Ethanol can be blended into gasoline.
4. The Federal Government will pay people to make such ethanol.
5. The cost of gasoline is high and looks to be headed higher.
6. A big chunk of the cost to make ethanol is in the corn itself.
7. The cost to grow corn is well understood and more stable than the cost of gasoline.
In looking back, everyone was right except for #7. The cost of corn has risen faster than the cost of gasoline. As a result there are a lot of ethanol plants that facing hard times.
I could write the same list of "facts" for biodiesel, substituting soy or canola for corn. While it doesn't get the same degree of negative press, there are many well-intentioned biodiesel plant owners who are faced with buying palm oil from Southeast Asia that has a lot of environmentally negative baggage with it.
Growing palm for the oil is amongst the most productive source of agricultural oils on a land use basis. It also grows best in areas that have extensive biodiversity. The end result often being that the biodiesel plant owners are faced with the prospects of choosing between closing their plant or supporting the bulldozing of tropical rain forests to get cheaper feedstock.
Where with this surge in demand show up next? I'm already hearing about rapid changes in the cost of woody biomass - sawdust, waste wood, etc. It is clear to me that this is a trend. In fact, while NDA's prevent me from saying what the "waste" feedstock is, I'm seeing or hearing simultaneous proposals to convert the same nusiance feedstock in the same geographic region, a feedstock that people now pay to have hauled away. The end products are energy and more valuable recovered co-products.
If your project economics are predicated on getting paid to take the raw materials you use, suddenly having the shoe on the other foot is going to be a huge setback. While everyone strives to have some kind of protected intellectual property, there often isn't much technical advantage to the individual patents and knowhow around mass and energy conversion.
What then is a developer to do? How do you carve out a business that is sustainable?
The best (and most difficult) way is to enter into long term contracts for your feedstock and your off-take (products, co-products, etc.) that covers the length of any loan against the project. Then at least, you can weather periods of low profit or no profit without the fear of foreclosure.
The problem is that long term forward contracts (as their called in the commodity business) are hard to come by. Even in the commodity exchanges, the most mature forward markets in existence, contract terms are usually measured in months not years.
One competitive advantage that impacts most of these opportunities however, is shipping cost. Smaller plants that are using locally available feedstocks to produce locally consumed energy or other products will have a natural advantage. The trick will be in finding the right balance between economies of production scale versus the cost of input and output transportation.
Does this then limit the developers' prospects for building a big business? Not necessarily. As McDonalds has proven so well, you can build a very big business with repeatable, profitable, smaller businesses. If the economic model for local waste to energy works in one community, it often can work in others. Developers who demonstrate their ability to create those smaller, profitable businesses will find many organizations who are interested in helping to bankroll the next 5 or 10 of them.
The long term advantage will belong to the first movers. The bold, smart developers will get their chance at financial success based on their savvy and execution in the roll out of these smaller plants. As it should be.
