A Call to Action Summit: Ensuring Iowa's Leadership in the Bioeconomy

A Call to Action Summit: Ensuring Iowa's Leadership in the Bioeconomy
November 28 2006 | Iowa State University |

Bioeconomy summit spotlights Iowa's future
by Diana Pounds
Inside Iowa State | December 8, 2006

In the biofuels race, Iowa leads the pack. Superior corn-growing attributes and entrepreneurial farmers have propelled Iowa to the No. 1 ethanol-producing state in the nation.

Can the state hold that front-runner position? That was the question Nov. 28 when representatives of academia, industry and government joined other state leaders on campus to talk biofuels.

Their task, as laid out by President Gregory Geoffroy, who called the summit, was to begin anticipating changes on the biofuels front and lay the groundwork for continued Iowa leadership in the field.

The day-long summit on "Ensuring Iowa's Leadership in the Bioeconomy" drew a crowd. Approximately 450 participants spent the morning learning about bioeconomy issues from several experts and the afternoon brainstorming about ways to maintain Iowa's leadership in the field.

Thermochemical Ethanol Via Lignocellulosic Biomass

Thermochemical Ethanol via Indirect Gasification and Mixed Alcohol Synthesis of Lignocellulosic Biomass

1. Executive Summary
This work addresses a policy initiative by the Federal Administration to apply United States Department of Energy (DOE) research to broadening the country’s domestic production of economic, flexible, and secure sources of energy fuels. President Bush stated in his 2006 State of the Union Address: “America is addicted to oil.” To reduce the Nation’s future demand for oil, the President has proposed the Advanced Energy Initiative which outlines significant new investments and policies to change the way we fuel our vehicles and change the way we power our homes and businesses. The specific goal for biomass in the Advanced Energy Initiative is to foster the breakthrough technologies needed to make cellulosic ethanol cost-competitive with corn-based ethanol by 2012.

In previous biomass conversion design reports by the National Renewable Energy Laboratory (NREL), a benchmark for achieving production of ethanol from cellulosic feedstocks that would be “cost competitive with corn-ethanol” has been quantified as $1.07 per gallon ethanol minimum plant gate price. This process design and technoeconomic evaluation addresses the conversion of biomass to ethanol via thermochemical pathways that are expected to be demonstrated at the pilot-unit level by 2012. This assessment is unique in its attempt to match up:

***Currently established and published technology.
***Technology currently under development or shortly to be under development from DOE Office of Biomass Program funding.
***Biomass resource availability in the 2012 time frame consistent with the Billion Ton Vision study.

Indirect steam gasification was chosen as the technology around which this process was developed based upon previous technoeconomic studies for the production of methanol and hydrogen from biomass. The operations for ethanol production are very similar to those for methanol production (although the specific process configuration will be different). The general process areas include: feed preparation, gasification, gas cleanup and conditioning, and alcohol synthesis & purification.

The cost of ethanol as determined in this assessment was derived using technology that has been developed and demonstrated or is currently being developed as part of the OBP research program. Combined, all process, market, and financial targets in the design represent what must be achieved to obtain the reported $1.01 per gallon, showing that ethanol from a thermochemical conversion process has the possibility of being produced in a manner that is “cost competitive with corn-ethanol” by 2012. This analysis has demonstrated that forest resources can be converted to ethanol in a cost competitive manner. This allows for greater flexibility in converting biomass resources to make stated volume targets by 2030.

Iowa Power Fund

Des Moines RegisterWednesday, May 23, 2007

Governor signs bills fostering renewable energy

The state will spend $100 million over four years to aid development.


Ames, Ia. - It's official: Iowa will pump $100 million into boosting its renewable fuel research and production. Gov. Chet Culver signed legislation Wednesday that will allocate the money to promote such things as wind power and ethanol-like improvements over the next four years. Culver called the bill historic legislation, telling a crowd of about 50 people at Iowa State University "Our 21st century Iowa expedition starts now." Said Culver, "This will begin the process of making our entire state a laboratory so that we remain a cutting edge of all forms of renewable energy."

The legislation creates a new Office of Energy Independence. The office will pursue new research investments with government and private businesses, as well as help create an Iowa energy independence plan. The goal is to wean Iowa from its dependence on foreign oil by 2025, Culver said.

Iowa State University President Gregory Geoffroy praised the legislation Culver signed. "We are going to do for biomass what George Washington Carver did for the peanut, and it won't be for peanuts," Geoffroy said. He was referring to the internationally famous scientist, who was a student and later a faculty member at what is now Iowa State. Carver is best known for developing multiple uses for the peanut, including peanut butter.

The $100 million in the Iowa Power Fund will be spent over the next four years. Culver said he plans to name the director of the Office of Energy Independence and appoint seven of the 11 Power Fund board members around July 1. The other four members of the board will be state officials, such as the director of the Iowa Department of Natural Resources. Culver predicted the fund would leverage "hundreds of millions, if not billions of dollars" of additional investments in the state from private and federal sources.



The fund will be available to people working in research, development or implementation of new ways to reduce dependency on foreign oil through renewable energy, advancements in biofuels, or energy efficiency. The office that will accept and review applications for money from the Power Fund is expected to be in place around July 1.

Brothers of Invention Turn Cobs Into Potential Gold

Des Moines Register | Published May 13, 2007

Brothers of invention turn cobs into potential gold

Twins’ innovation collectscorn waste for biofuel use


Nebraska City, Neb. — For the past 10 years, harvesting corn and selling the cobs has been a humble little business for Ty and Jay Stukenholtz, 34-year-old twin brothers. By trial and error, computer designing, tinkering and banging away, the Stukenholtz brothers, who farm the 350-acre family farm near Nebraska City, came up with a way to harvest corn cobs and kernels at the same time and keep the materials separate. Until now, the brothers’ invention has had limited appeal because of the small market for corn cobs, save as cattle feed or in some limited industrial uses.

But that might be about to change as ethanol makers look into producing ethanol from crop residue and other biomass, including the cobs, leaves and stalks from corn plants.
“Our goal was to build a cleaner that can attach to the back of a combine with a tank on top for the cobs,” Ty said.
“It’s universal, so it fits on any combine,” said Jay, finishing Ty’s thought.
Ty and Jay are identical twins except for the fact that Ty is right-handed and Jay is left-handed. Their thinking is as complementary as their dexterity, they say, so they form two halves of an inventing whole.
In January, Pihlblad and the Stukenholtz twins formed a limited liability company called Ceres Agriculture Consultants, based in Waukee. The company intends to produce or license the twins’ biomass collection system to a farm equipment manufacturer and provide other renewable fuel services.
The brothers have made about a dozen different versions of their cob collector. Their 10th version is attached to a 2388 Case IH combine.

As the combine moves through the field, it pulls whole corn plants into the corn head mounted on the front of the combine. Corn kernels are separated from the cobs and other parts of the corn plant and the kernels are routed into the combine’s conventional grain storage tank. The Stukenholtz brothers’ innovation fits on the back of a combine, where the leaves, cobs and other shredded corn plant residue is normally flung out and onto the ground. Instead, the brothers have come up with a device that consists of a series of sieves and fans that separate the different parts of the corn residue as it moves to the back of the combine. The cobs, once separated from the other parts of the corn plant, are sent to a tank that sits atop the combine. The tank is designed to slide to one side so it can discharge the cobs into a wagon.

Other plant residues like soybean pods also can be gleaned by setting the sieves and fans in a different configuration.

It’s been 10 years since the Stukenholtz brothers started tinkering around with a corn cob collector. They’ve made about a dozen versions, including one that is being used by Dan Allen of Allendan Seed Co. in Winterset.
But it’s in the emerging field of cellulosic ethanol that the Stukenholtz brothers and Pihl-blad think their machine will really take off.
Poet, the ethanol producer formerly known as Broin Cos., plans to use corn cobs to make ethanol at its Emmetsburg plant. Poet has said the plant will need 450 to 500 tons of cobs a day to make cellulosic ethanol.
Although Birrell said he hasn’t seen the Stukenholtzes’ attachment at work, cellulosic ethanol production will need innovations like theirs to solve roadblocks to produce ethanol from biomass.

New Technologies in Ethanol Production

New Technologies in Ethanol Production

(Agricultural Economic Report Number 842)

Fuel ethanol production has increased steadily in the United States since the 1980s, when it was given impetus by the need to reduce energy dependence on foreign supplies. The momentum has continued as production costs have fallen, and as the U.S. Clean Air Act has specified a percentage of renewable fuels to be mixed with gasoline. The fraction of annual U.S. corn production used to make ethanol rose from around 1 percent in 1980 to around 20 percent in 2006, and ethanol output rose from 175 million gallons to about 5.0 billion gallons over the same period. New technologies that may further increase cost savings include coproduct development, such as recovery of high-value food supplements, and cellulosic conversion. High oil prices may spur the risk-taking needed to develop cellulose-to-ethanol production. Developments such as dry fractionation technology, now commercially viable, may alter the structure of the industry by giving the cheaper dry-grind method an edge over wet milling. Dry milling requires smaller plants, and local farmer cooperatives could flourish as a result. Though improvements in processing and technology are important, however, the fluctuating price of inputs such as corn, the cost of energy alternatives, and environmental developments play larger roles in the fortunes of the

Launch of The Bioenergy Blog

The Bioenergy Blog is a devoted to the identification and promotion of key primary and secondary literature relating to biorenewable fuels, most notably bioethanol and biodiesel.

It will focus on the technical aspects and technologies associated with the production of these fuels, as well as other bio-based products and commodities.

It will seek to identify significant monographs as well as conference proceedings, dissertations and theses, reports and other grey literature, as well as popular works and relevant digital sources, notably DVDs and significant Websites. Select major review articles will also be profiled.

The Bioenergy Blog was formally established on May 7 2007.

With proper support, it is hoped that the major publications and presentations cited in The Bioenergy Blog will be compiled into a Web-based annotated bibliography.
