According to a recent study by the U.S. Department of Agriculture (USDA), using switchgrass pellets could be a cheaper source of energy, instead of fuel oil to heat homes and businesses in the Northeast. Agricultural Research Service (ARS) researcher Paul Adler led efforts on a lifecycle analysis that compared costs of energy generation from coal, natural gas, fuel oil, and switchgrass in the form of energy-dense cubes, briquettes, and pellets.
The researchers calculated the economic outlays associated with switchgrass production throughout the supply chain, as well as greenhouse gas emissions generated by switchgrass production, densification, and conversion to heat and power. This included the first lifecycle inventory of switchgrass seed production and greenhouse gas emissions associated with seed production.
The analysis indicated that 192 pounds of “carbon dioxide equivalent,” or CO2e, was emitted for every ton of switchgrass dry matter that was sown, harvested, and delivered to densification plants for processing into pellets. CO2e is a measurement used to compare the emissions from various greenhouse gases based upon their global warming potential.
The researchers calculated that using switchgrass pellets instead of petroleum fuel oil to generate one gigajoule of heat in residences would reduce greenhouse gas emissions by 146 pounds of CO2e. Totaling all costs associated with installing an appropriate residential heating system and fuel consumption, the team concluded that each gigajoule of heat produced using switchgrass pellets would cost $21.36. Using fuel oil to produce the same amount of heat would cost $28.22.
Adler is now working with Plainview Growers to determine how the carbon footprint differs between heating greenhouses with biomass and heating them with fuel oil. The results of the research were published in the journal, Environmental Science & Technology.
International company Abengoa has announced the creation of a new American subsidiary, Abengoa, US, which will be responsible for all its business in the country. The formation of the new subsidiary supports the company’s strong commitment to the U.S. market.
According to the company, Abengoa US has assets in excess of $5.8 billion, more than $1.7 billion in shareholders’ equity, and its revenues account for approximately 20 percent of the company’s total sales. Today, U.S. projects are coordinated from three offices located in Washington D.C., St. Louis and Denver with R&D+i centers in Denver and St. Louis. In addition, the company has projects completed or underway in 12 sates.
Currently,, Abengoa US is engaged in various landmark projects in the country, including Solana, the world’s largest solar plant using parabolic-trough solar-thermal technology based in the Arizona desert, which has up to six hours of electricity storage, and one of the first commercial second-generation bioethanol plants located in Hugoton, Kansas, which will come into operation at the end of this year.
With the 112th Congress unable to come to terms and pass a new Farm Bill, the current bill was extended for nine months while the 113th Congress works to pass a 2013 Farm Bill. Although the bill is extended as part of the American Taxpayer Relief of 2012, it was extended without energy title funding that includes programs such as the Rural Energy for America Program (REAP), Biomass Crop Assistance Program (BCAP) Biorefinery Assistance Program (BAP) and the Biobased Markets Program (Biopreffered). The news was not greeted with enthusiasm by the agricultural and renewable energy industries.
“We are deeply disappointed that Congress ignored the bipartisan bill drafted by House and Senate Ag Committee leaders,” said Lloyd Ritter, Ag Energy Coalition co-director. “By eliminating mandatory funding for energy title programs, the agreement cuts short vitally important job creation and economic growth in rural America.”
According to Ritter, these programs have helped to revitalize rural America, develop new agricultural markets, and reduce the need for direct payments to farmers. In addition, says Ritter, these programs have unlocked private capital for construction of the nation’s first cellulosic and advanced biofuel biorefineries. As part of this movement, more than 150,000 acres of underutilized, such as marginal land, in more than 150 countries.
Last year, the U.S. Senate passed a version of a five-year Farm Bill that set mandatory levels each year for renewable energy and energy efficiency programs. A slightly different version of a five-year Farm Bill was passed by the House Agriculture Committee that provided discretionary funding for these programs. Draft legislation for a one-year extension of the current Farm Bill agreed to by the House and Senate Ag Committee leaders and released at the end of December 2012 set mandatory funding levels for 2013. However, the extension did not pass with these funding levels included and will ultimately cause harm to the momentum of agriculture’s role in renewable energy.
What do people in the Southeast think about biofuels? Do they support biofuel ventures? Who will grow the biomass? Will those in established industries fight against it? These are just a few of the questions researchers from the University of Georgia and the U.S. Forest Service are asking as part of studies in locations throughout the Southeast suited for biomass development.
The researchers will use a mix of ethnographic methods to help understand public opinion about bioenergy and also to provide policymakers and business owners with the information they need to make sustainable energy production viable throughout communities.
“We’re planning to work on the ground throughout the Southeast,” said Sarah Hitchner, a co-investigator and post-doctoral research associate at UGA’s Center for Integrative Conservation Research. “A lot of people talk about biofuels as being an obvious win-win, but it’s more complicated than that.”
Supported by a grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture, which funds research projects on sustainable bioenergy through its Agriculture and Food Research Initiative, the research team will begin in Soperton, Georgia-formerly home to Range Fuels and now the Freedom Pines Biorefinery owned by LanzaTech-and then moving on to other areas in Georgia, Alabama, Mississippi, Louisiana, Florida and North Carolina. While visiting local communities, the researchers will participate in the daily activities of community members and conduct in-depth interviews with a variety of stakeholders, such as landowners, industry representatives, potential employees and county commissioners.
“A big part of this kind of research is to listen to as many perspectives as possible,” said Peter Brosius, professor of anthropology in the Franklin College of Arts and Sciences, director of the Center for Integrative Conservation Research and co-investigator in the study. “From there you begin to see patterns emerge.” Continue reading
The United States Department of Agriculture (USDA) has awarded $10 million in research grants to help develop production of bioenergy and biobased products. Ag Secretary Tom Vilsack made the announcement while visiting Michigan State University, one of the grant winners.
While there, Vilsack mentioned the growth potential of biobased products as detailed in a recent study by Iowa State University (funded by USDA) that found that while biobased products in automobile manufacturing is increasing, there are still many parts that can be replaced with biobased materials.
“USDA and President Obama are committed to producing clean energy right here at home, to not only break our dependence on foreign oil, but also boost rural economies,” said Vilsack. “These projects will give us the scientific information needed to support biofuel production and create co-products that will enhance the overall value of a biobased economy. Today, with a strong and diversified U.S. agricultural sector, the American automobile industry has a greater incentive for expanding use of biobased products while supporting good-paying jobs here in the United States.”
USDA’s National Institute of Food and Agriculture (NIFA) awarded the grants through the Agriculture and Food Research Initiative (AFRI). AFRI’s sustainable bioenergy challenge area targets the development of regional systems for the sustainable production of bioenergy and biobased products that: contribute significantly to reducing dependence on foreign oil; have net positive social, environmental, and rural economic impacts; and are compatible with existing agricultural systems.
Projects were awarded in four areas: 1) policy options for and impacts on regional biofuels production systems, 2) impacts of regional bioenergy feedstock production systems on wildlife and pollinators, 3) socioeconomic impacts of biofuels on rural communities, and 4) environmental implications of direct and indirect land use change.

Bielfeld University Professor Dr. Olaf Kruse has a class he won’t forget. His biological research team has made what they consider to be a groundbreaking discovery – the green alga Chlamydomonas reinhardtii not only engages in photosynthesis, but is also able to draw energy from other plants. The team believes this could have a major impact on the future of bioenergy. Findings were released in the online journal, Nature Communications.
According to Kruse, it was believed that only worms, bacteria and fungi could digest vegetable cellulose and use it as a source of carbon for their growth and survival. In contrast, plants engage in photosynthesis of carbon dioxide, water and light. Yet through a series of experiments, Professor Dr. Olaf Kruse and his team cultivated the microscopically small green alga species in a low carbon dioxide environment and observed that when faced with such a shortage, these single-cell plants drew energy from neighboring vegetable cellulose instead.
So how does this work? Kruse explains that the alga secretes enzymes (so-called cellulose enzymes) that ‘digest’ the cellulose, breaking it down into smaller sugar components. These are then transported into the cells and transformed into a source of energy and abracadabra – the alga can continue to grow.
“This is the first time that such a behaviour has been confirmed in a vegetable organism,” noted Professor Kruse. ‘That algae can digest cellulose contradicts every previous textbook. To a certain extent, what we are seeing is plants eating plants.”
So does this trick happen with also forms of alga? Kruse says preliminary findings indicate this is in fact the case. And based on this hypothesis, this unique property of algae, the presence of celulose enzymes could be of interest for bioenergy production. There would no longer be a need for organic materials to feed the fungi that are currently used to extract the enzymes needed to break down the cellulose.
The INEOS New Planet BioEnergy (INPB) biorefinery is now producing renewable power using its bioenergy technology. The electricity produced is being used to power the facility and the excess power is being added to the grid. At full production, the Center is expected to produce 8 million gallons of advanced cellulosic bioethanol and six megawatts (gross) of renewable power using renewable biomass.
Here is how the process works. Biomass feedstock, including yard, vegetative and agricultural, waste goes through a gasification process, and syngas is created. Heat is then recovered from the hot syngas and fed into a steam turbine and used to generate electricity. The electricity then powers the Center and the excess does onto the grid to help power homes in the local Vero Beach, Florida community.
“The production of renewable power is a significant benefit of our technology. The power generated improves the energy efficiency and greenhouse gas savings of the facility while contributing to the base load of renewable electricity for the local community,” said Peter Williams, CEO of INEOS Bio and Chairman of INPB. “We look forward to rapidly rolling out this technology globally to provide the benefits of bioethanol and renewable power from waste to local communities.”
INPB’s facility was the first large-scale project in the U.S. to receive registration from the EPA using vegetative waste materials as the primary feedstock.
Biodico has signed an agreement with the U.S. Navy for the development and evaluation of advanced biofuels and bioenergy. The goal is to jointly develop renewable fuel and energy technologies that are appropriate for use at U.S. Naval and Department Of Defense (DOD) facilities worldwide. The co-project is supported, in part, by grants from the California Energy Commission.
The collaboration between the Navy and Biodico will optimize the operation of sustainable biorefineries producing renewable petroleum diesel equivalent liquid fuels, bio-based products and energy using renewable resources. The goal is to lower the per gallon cost of production of the alternative energy source and also to push the advanced technology into the marketplace for commercial scale production.
Biodico’s President and Founder, Russell Teall, said, “As part of this agreement we are building a sustainable biorefinery at Naval Base Ventura County that will produce biofuel and bioenergy at prices competitive with unsubsidized conventional fuel and power. The facility is privately funded, with some of the innovations supported by grants from the California Energy Commission. Sen. Pavley’s landmark initiatives have helped make this project possible.”
Through on-site production of liquid biofuels, biobased products and alternative energy, the Navy can get closer to reaching its goal of reducing its dependence on petroleum by 50 percent by 2020. This, in turn, will provide the Navy access to secure forms of energy. Work under the new contract will include a range of technologies including but not limited to transesterification, gasification, gas to liquids, hydrogenation, anaerobic digestion, catalysis, and the production and processing of feedstocks and co-products.
“This announcement is an exciting outcome of the collaboration between Biodico, the Navy and the California Energy Commission,” said California State Senator Fran Pavley (D-Agoura Hills). “This work is a direct result of California’s commitment to reduce our dependence on foreign oil. The collaboration between Biodico, the Navy and the California Energy Commission will enhance our national security, provide new jobs and improve the environment. It will demonstrate and commercialize advanced biofuel and bioenergy technologies that will be utilized throughout the world. The integration of sustainable agriculture with renewable combined heat and power produced on-site will produce inexpensive advanced biofuels.”
