The Biofuel Bubble
A horde of startups have smart ideas. But the challenges are many, and the winners likely will be Shell, BP, DuPont, and other majors
It's a bold vision: Replace billions of gallons of gasoline not with ethanol from corn or other food crops but with biofuels made from plants, such as prairie grass in Tennessee pastures or algae percolating in Florida. Such a move would slash dependence on oil, create thousands of jobs, and reduce emissions that contribute to global warming. In the U.S., the idea has powerful political support. Congress has decreed that the country must be using 21 billion gallons of "advanced" biofuels a year by 2022. Washington is backing that goal with tax breaks, loan guarantees, and scores of millions of dollars in grants, with more support expected in upcoming energy bills. These inducements and the vast potential market have stimulated investments of more than $3 billion and spawned a new industry.
More than 200 companies, from 12-person startups to oil giants, are developing next-generation biofuels using a bewildering array of technologies. Pilot and demonstration plants are operating or are under construction from Florida to California. "We can have it all: more fuel, more food, and fewer carbon emissions," says John B. Howe, vice-president of Verenium (VRNM), a Cambridge (Mass.) company that makes ethanol from sugarcane waste at a demonstration plant in Jennings, La.
Yet behind the very real innovations and investments, the brash claims and the breathless headlines, lies an inconvenient truth. Replacing petroleum with biofuels is a tough business. Even as the industry develops, many of the companies—probably most—will not survive. "We've seen a venture capital-led bubble," says Alan Shaw, CEO of Codexis, a Redwood City (Calif.) manufacturer of enzymes used to make drugs, chemicals, and biofuels. "I cannot see how the small companies can build a business and still get a return to their original investors. The numbers just don't add up."
Nor will many Americans soon be filling their gas tanks with these next-generation fuels. Industry executives concede they'll fall far short of the mandated 2010 level of 100 million gallons of biofuels made from cellulosic materials such as prairie grass or cornstalks. Meeting the 2022 goal is also unlikely. It would require not only building hundreds of fuel factories—at a cost of $500 million or more each—but also surrounding each one with thousands of acres of land planted with energy crops such as prairie grass. "We're talking about a fairly substantial transformation of the rural economic landscape," says Jack Huttner, vice-president of DuPont Danisco Cellulosic Ethanol, a joint venture of Danisco and DuPont (DD) that is building a demonstration plant in Tennessee.
These difficulties don't mean advanced biofuels aren't coming, or that they won't play a crucial role in fighting climate change. But everything will happen more slowly than many venture capitalists say. And the probable winners will be those with deep pockets and patience, such as Royal Dutch Shell (RDS), BP (BP), DuPont, agriculture giant Archer Daniels Midland (ADM), or the rare startup with revenues from another business, such as making drugs. For the rest, the demonstration biorefineries now being built are more like high-stakes auditions than a step in the process of becoming commercial biofuels producers. "The business model that makes sense for most of us is demonstrating the technology and getting it into the hands of those who have balance sheets," says Bill Roe, CEO of biofuel producer Coskata in Warrenville, Ill.
