About the author: Jeremy Martin is a scientist with expertise in the technology, lifecycle accounting, and water use of biofuels. He is working on policies to help commercialize the next generation of clean biofuels (made from waste and biomass rather than food) that can cut U.S. oil dependence and curb global warming. He holds a Ph.D. in chemistry with a minor in chemical engineering. See Jeremy's full bio.

Policy Matters: Why Clean Fuels Forecasts Come Up Short

Cellulosic biofuel facilities are opening this year to much fanfare and a renewed promise that we can look forward to a quickly increasing supply of clean, non-food biofuels. At the same time, forecasts about the future of cellulosic biofuel have recently gotten more pessimistic, with the Energy Information Administration forecasting a plateau once these first plants open. What to believe? I use a simple model to show how progressive, consistent clean fuels policies will lead to lower costs over time. Read More

Production Begins At Second Cellulosic Biofuel Facility

You don’t often hear Kansas and Spain mentioned in the same sentence. Yet today Spanish company Abengoa is bringing another big cellulosic biofuel facility online in Hugoton, a small community in the Southwest corner of the state. This is the second big plant starting up this year, showing that after some predictable yet highly scrutinized delays, the cellulosic fuel industry is truly beginning to establish itself and making critical contributions to oil savings and climate goals.

5 Things I Learned in Iowa about Biofuels

In July my colleagues and I, together with the Great Plains Institute, organized a Cellulosic Summit in Iowa. We brought together experts in clean transportation (many from California) with experts in sustainable agriculture (many from Iowa) to see for themselves the latest developments in cellulosic biofuel commercialization.  Read More

What Do Ice Cream and Electric Vehicles Have in Common?

It’s a big day on the road to Half the Oil, and a celebratory ice cream cone is in order. Why? Two reasons. First, it’s summer in DC, and it’s hot and muggy. Second, in announcing late last week that they were allowing several new biofuel production methods, known as “pathways,” to qualify under the Renewable Fuel Standard (RFS), the Environmental Protection Agency (EPA) included electric vehicles charged on biogas made from dairy waste (yes, cow manure) as well as other sources of waste based fuel. It’s further proof our biofuels policy is about more than just corn ethanol. Read More

New Study on Corn Waste Biofuel’s Emissions: Worthy Topic, Flawed Conclusion

This blog appeared as a guest blog on the National Geographic Great Energy Challenge

A recent study in Nature Climate Change is attracting a lot of attention because of its headline grabbing claim that cellulosic ethanol made from crop residues produces higher carbon emissions than gasoline. (See related blog post: “Corn Waste for Biofuel Could Boost Emissions, Study Says.”) Read More

Biodiesel Update: Now with More Soy

I’ve said before that the food versus fuel debate is about more than corn, and specifically that using a large share of America’s vegetable oil for fuel would be counterproductive, and would do more to expand unsustainable palm oil production than to sustainably cut oil use and reduce carbon emissions.

Through the Blend Wall or Not: Experts Weigh in on Ethanol Blends and the Future of Biofuels

How much ethanol can we use? Not as much as the corn ethanol lobby says, but considerably more than the oil industry wants you to think. The trench warfare between oil and corn ethanol interests over the future of biofuels policy distracts us from the more important questions. To understand the practical constraints facing the near term implementation of biofuel policy, it’s important to remember that there are 15 million flex fuel cars on America’s roads today capable of running on blends of 85 percent ethanol (E85) – it just isn’t broadly available. The implications reach beyond just corn ethanol. Read More

The EPA and Biofuels: Smart Goals, but an Outdated Roadmap

It may sound backwards, but the EPA’s proposal at the end of last week to reduce the 2014 biofuels mandates in the Renewable Fuels Standard (RFS) is just what we need to make sure we realize the promise of truly low carbon biofuels that cut oil use while minimizing competition with food. But while adjusting mandates in light of up-to-date data is smart, the EPA’s proposal goes too far, and could slow forward progress. Before finalizing the rule, the EPA should carefully balance near term challenges with the need to maintain progress toward long term oil saving and climate goals. Read More

Talking Biofuels: A Conversation with University of Illinois Biofuel Experts

I’ve long admired and relied on the work of the ag economists at Farmdoc Daily, particularly Scott Irwin and Darrel Goode. They’ve done a lot of insightful analysis on the agricultural market impact of biofuel mandates under the Renewable Fuel Standard — analysis that I rely on to make the case for a flexible, cautious approach to implementing the standard to ensure our clean fuel goals don’t come into conflict with food security and climate protection. I was lucky enough to spend a day recently with Scott, Darrel and other researchers at their home base of the University of Illinois, talking over the future of biofuels.

The Future of Biofuels Part 3: Biodiesel

Faithful readers will have seen my data-based analysis of the US mandates for biofuels under the Renewable Fuel Standard (RFS) and the U.S. Environmental Protection Agency’s (EPA)  big choices on how to administer the program looking ahead. These choices highlight how the “food versus fuel” debate extends far beyond corn. The bottom line is that if the agency expands the RFS advanced mandate to make up for the slow commercialization of non-food “cellulosic” fuels, it will undermine the environmental and fuel security goals of the fuel standard, and contribute to food supply problems worldwide.
