Biomass Upstarts

These four crops are generating additional revenue for farmers. AGCO brands are helping make that happen.

Switchgrass
What’s not to love about switchgrass? The perennial develops a strong root system that holds highly erodible land in place. Plus, those farmers who’ve already planted switchgrass know about its long-lasting stands—at least 10 years—and that it makes great wildlife habitat. Now there is better news: more biofuel markets in the future.

Corn Stover
Since ample supplies of stover are a given, using corn stover for biofuel seems like the perfect plan. For 2013, corn acres in the U.S. were estimated at 97 million and Canadian acres at 3.6 million, with 2.5 million of those in Ontario. There isn’t much of a learning curve either. If you can grow corn, you automatically know how to grow stover.

Miscanthus
Miscanthus, a perennial, is another up-and-comer for the biomass market. However, says Iowa State University Professor Emily Heaton, “I spend a lot of time managing grower expectations about the crop. If you want to plant a half-acre or an acre to play with, that’s fine. But let’s [watch what happens] with the corn stover market first.”

Sweet Sorgham
Sweet sorghum is tailor made for biofuel production. “It is easier to make ethanol out of it than [with] corn,” says University of Missouri extension agronomist Gene Stevens. “It is already in sugar form. Just add yeast to start the fermentation.” And as an annual, producers do not have to make a long-term commitment.

Thermochemical Processing: Converting Biomass into Fuels and Chemicals

By: Robert C. Brown, Director, and Robert Mills, Communications Specialist, Bioeconomy Institute, Iowa State University

The use of fermentation to produce ethanol from corn and other biomass is well known in the agricultural world. There are, however, other technologies that can convert biomass into fuels and chemicals. Foremost among these are thermochemical processes, which use heat and catalysis to break down biomass to intermediates that can be upgraded to transportation fuels.

Thermochemical processing uses heat and pressure to convert various types of feedstocks into fuels and chemicals.

Thermochemical processing uses heat and pressure to convert various types of feedstocks into fuels and chemicals.

One advantage of thermochemical processing is that the end result can be “drop-in fuels,” those that are fully compatible with the existing fuel infrastructure. While not perfect, these drop-in fuels are good enough to run in today’s engines without modification.

Another advantage to thermochemical processing is that most systems can work with a variety of biomass feedstocks. Often the feedstock is lignocellulosic biomass, such as corn stover, switchgrass, miscanthus, wood, etc. But thermochemical processing can also use lipid-rich biomass such as distillers dried grains and algae as well as mixed wastes from commercial and municipal sources.

There are two basic types of thermochemical processing, indirect and direct liquefaction. Indirect liquefaction includes gasification, where the solid biomass is heated to create synthesis gas, or syngas, that is subsequently upgraded to liquid fuels. Various catalysts are then used to convert the gas into alcohols or hydrocarbons. The advantages of gasification is that the process produces a uniform product and it is commercially proven. Gasification, however, requires technologies to clean the gases, which are still under development, and the capital costs can be high.

Direct liquefaction uses heat and pressure to convert the biomass into liquids which can then be further upgraded into finished products. Direct liquefaction includes pyrolysis and solvent liquefaction. In the case of pyrolysis, biomass is heated in the absence of oxygen. The process yields bio-oil, syngas, and a solid product known as biochar. The bio-oil can be upgraded to drop-in fuels. Pyrolysis can be performed at relatively small scales, allowing it to take place close to the source of biomass rather than moving biomass to one large, centralized processing facility. One of the major problems with pyrolysis is that the bio-oil is unstable, complicating its conversion into fuels.

Iowa State University researchers discuss a new pyrolysis pilot plant during its construction. The plant is now up and running and is used to research the multi-stage fractionation of bio-oil, a process that promises a way to economically convert biomass into many value-added products.

Iowa State University researchers discuss a new pyrolysis pilot plant during its construction. The plant is now up and running and is used to research the multi-stage fractionation of bio-oil, a process that promises a way to economically convert biomass into many value-added products.

At Iowa State University, we have invented a process to condense the pyrolysis gases in fractions, resulting in better, more stable products. The economics of fast pyrolysis are promising. In addition to producing fuels and chemicals from the bio-oil, the biochar may also have economic value. Consisting mostly of carbon, biochar can be used a soil amendment, helping retain moisture and nutrients. There is also research underway to use biochar as a filter medium for purifying water.

Solvent liquefaction, or solvolysis, is similar to pyrolysis except that it is performed in a solvent at elevated pressure. Though the fundamental chemistry of solvolysis is not well understood, the technology has promising economics. The process can upgrade bio-oil in a way similar to oil refining, and it can create sugars which can be further upgraded without expensive enzymes.

In addition to extensive research into thermochemical technologies, there are also many efforts underway to commercialize these technologies. Like all start-ups, these efforts have met with various degrees of success. There are, however, several pilot-scale systems being tested and commercial plants being built.

Bioenergy is a complex topic. There are many pathways from raw material to finished product. What’s more, bioenergy technology must be viewed in context of larger energy issues and policies. You can learn more in a book written for the general public, “Why are We Producing Biofuels,” by Robert C. Brown and Tristan R. Brown. The book is available on Amazon.

Rural Hospital’s Future Is Bright Thanks to Biomass

Biomass, as a sustainable fuel, does more than just help the environment—it saves lives. Many rural hospitals have antiquated boiler systems that burn oil for fuel during the cold winter months. This is not a sustainable heat source, and the cost is putting many of them in the red. These hospitals often are the only close access to medical care in low income communities.

Biomass Hospital

Piedmont Geriatric State Hospital in Burkeville, Virginia, is using biomass to keep its buildings warm during those long winters. The hospital burns around 3,000 tons of native warm season grasses (NWSG) as biofuel, supplied by FDC Enterprises, from November to May. The hospital saves, on average, more than $1,300 per day during those seven months.

On an energy basis, biomass is roughly one-third the cost of fuel, which quickly adds up. Glenn Farris stated, “For many rural hospitals, being able to save over $200,000 per year is the difference between staying open or closing their doors. It can also be the way to bring that next important lifesaving machine or a new doctor to their facility. It can’t help but make you feel good to know you work for a company and in an industry that can make great things like this happen.”

By using biomass energy, hospitals can save money normally used to heat the building and instead better serve the community. Biomass is a win for rural hospitals, the communities they serve and the environment. To learn more about AGCO Biomass solutions, please visit: http://bit.ly/AGCOBiomass.

The King of Collection

Little known to our dealers and for many of our employees is the fact that our large square baler, the 2170XD and now the 2270XD, is recognized as the “King of Collection” for the baling of corn stover and wheat straw for the fledgling cellulosic ethanol industry. For over 5 years, AGCO has been working with both leading industry and university associates to develop an economical biomass feedstock supply chain. Now our balers are the centerpiece of the supply chain critical to the success of the first 3 major projects for the industry. These three projects are Abengoa’s Hugoton, KS project; Dupont’s Nevada, IA project; and POET/DSM’s project in Emmetsburg, IA. Each one is making ethanol from corn stover. Taken together these projects will require over 1,000,000 dry tons of material or roughly 1.8 million bales of which over 1.5 million will be large squares. With the corn harvest lasting only 6-8 weeks, to say there is intense activity for the baling of corn stover is a huge understatement.

Whether collecting this material for his or her self or having a professional harvester do it, this is a source of additional income for our farmers. Data has also shown an additional benefit resulting from this undertaking of residue management. With corn yields continually increasing, our farmers are producing rising amounts of corn stover as well. In fact so much residue is available after harvest that leaving it all on the field is not providing the same benefit it has in the past. The evidence is clear that removing some of the stover results in better yields in a corn on corn rotation. Uniformity of seed placement and depth, faster soil warming, less nitrogen fixing and less disease all help increase yields from 5-10%; this with the added benefit of less tilling.

Last year, during the 2013 corn harvest we had over 100 of our 2170’s and 2170XD’s at work making over 1,000,000 bales of corn stover for the ethanol industry. This amounted to over 90% of the large square balers working in this market. AGCO is working through product development to continue to improve our large square baler to support this dynamic new industry and our farmers. Better densities; data acquisition, management and evaluation; all helping to improve the operators of our equipment; and producing the most reliable and efficient large square baler in the market. This makes it easy to understand why our large square baler is considered the “King of Collection”.
