Following the Fall Semester UVM bioenergy course Bioenergy: Biomass to Biofuels, the University of Vermont will be offering a new bioenergy course this spring entitled Waste to Energy: Community Development Application. The course will again be taught by Anju Dahiya, cofounder of General Systems Research, LLC (GSR), lead biofuels instructor at the University of Vermont’s Rubenstein School of Environment and Natural Resources, and a Vermont Bioenergy Initiative algae for biofuel grant recipient. This course is open to both degree and non-degree students from any background or department, as well as farmers, entrepreneurs, and teachers interested in developing curriculum, or projects at school or college levels. This course is also approved for graduate credit.
In a Vermont post Act 148, the universal recycling law for solid waste, food waste, dairy farm manure, municipal wastes, landfill waste, carbon exhaust, nutrient runoff and other materials not being converted into value products are all resources that hold potential energy that can be developed in a sustainable way to power a local economy. This class focusing on waste sourced bioenergy comes on the heels of a promising results and continued work by Dahiya’s company GSR on incorporating algae into Green Mountain Power’s anaerobic digester at Nordic Farms in Shelburne, Vermont. The product serves as a strong example in which excess nitrogen and phosphorus in cow manure would find its way off farmland and end affecting health of natural water bodies, but instead is harnessed to make electricity and biofuel. As listed in the course catalog “the mission of this program is to provide hands-on instruction in all possible Bioenergy areas, support generation of related skilled workforce and stimulate sustainable energy production.”
Lectures will be held every on campus every Friday during the UVM spring semester from 12:00 pm to 3:00 pm, with 5 additionally required off campus field trips. The course required textbook, Bioenergy: Biomass to Biofuels, was edited by Anju Dahiya less than a year ago and represents a compilation of work from an extensive list of well-respected university extension programs, such as The University of Vermont Research Extension, as well as numerous national organizations including the US Department of Energy’s National Renewable Energy Laboratories.

Vermont Bioenergy Initiative proves biofuel potential for state and concludes ten year project
By: Ellen Kahler
Vermont can produce more of its own biofuel energy and the environmental and potential economic benefits of local bioenergy have been proven by the Vermont Bioenergy Initiative – a program of the Vermont Sustainable Jobs Fund. Since 2005, the Vermont Bioenergy Initiative has invested more than $2.5 million in innovative bioenergy research, projects, and people so Vermont can locally produce more of the state’s energy needs – from a variety of agricultural and algal feedstocks.
US Senator Patrick Leahy made the investment at this scale possible through Congressionally Directed Awards from the US Department of Energy (US DOE). The funding concludes in early 2016, at which point a complete impact report will be released by the Vermont Sustainable Jobs Fund, who has served as the intermediary between the US DOE and 52 individual Vermont bioenergy projects over the past ten years.
Research, development, and early stage demonstration projects have included:
- Investing in 2 on-farm methane digesters;
- Building farm-scale infrastructure to turn oilseed crops such as sunflowers into biodiesel to run farm tractors;
- Growing switchgrass and densifying it into “pucks” that are burned in a high efficiency commercial boiler instead of propane;
- Identifying the most lipid producing strains of native Vermont algae which can feed off the excess nutrients from methane digesters and can eventually be harvested to make biodiesel or jet fuel;
- Developing two “Biomass to Biofuels” college level courses which run repeatedly at UVM and VT Tech to inspire and train the next generation of bioenergy experts and technicians;
- Exploring the logistics of bulk wood pellet delivery systems to Vermonters’ homes;
- Organizing a number of learning opportunities and conferences for oilseed, grass and algae researchers, farmers and entrepreneurs to attend;
- Providing agronomic and engineering support to oilseed and grass farmers;
- Educating the general public about why the local production for local use of energy crops from Vermont farms and forests makes good economic and ecological sense.
The Vermont Bioenergy Initiative is a unique effort and one that is gaining resonance in other parts of rural America. The initiative’s resource website, www.VermontBioenergy.com is utilized by biofuel producers, educators, and technical service providers from across the country.
The work conducted over the past ten years by the Vermont Bioenergy Initiative to conduct research, provide technical assistance, and develop infrastructure in emerging areas of bioenergy will continue with the initiative’s partners at UVM Extension and the Vermont Agency of Agriculture, Food & Markets. As Vermont moves forward – being innovative and increasingly focused on generating renewable energy from the land and forests – the research and infrastructure the Vermont Bioenergy Initiative has invested in over the past ten years will endure and spawn the next wave of bioenergy development in the state.
Ellen Kahler is executive director of the Vermont Sustainable Jobs Fund (VSJF), a non-profit organization created by the State of Vermont to help develop Vermont’s sustainable agriculture, renewable energy, and forest product businesses. Since 2005, the Vermont Bioenergy Initiative has been a VSJF program that connects diversified agriculture and local renewable energy production for on-farm and community use by supporting research, technical assistance, and infrastructure development in emerging areas of bioenergy including biodiesel production and distribution for heating and transportation, oil crops for on-farm biodiesel and feed, grass for heating, and algae production for biofuels and wastewater management. Learn more at www.VermontBioenergy.com.
Algae for biofuel has been a long time component of the local biofuel production for local use model pioneered by the Vermont Bioenergy Initiative. At the forefront of these efforts has been Anju Dahyia, a VBI grantee, lead biofuels instructor at the University of Vermont, and president of General Systems Research (GSR) Solutions. When the Vermont Fuel Dealers Association received a USDA Rural Business Enterprise Grant to utilize waste materials from Vermont farms to produce sustainable distillate fuel, Anju and GRS Solutions were already in a prime positon to conduct the necessary research.
GSR is developing a method of producing algae biofuel to replace traditional fossil fuels in motor vehicles, heavy farm equipment, and even airplanes at Charlotte’s Nordic Dairy Farm as a second tier to the already operational anaerobic digesters contributing to Vermont’s distributed energy generation grid. The process to produce algal biofuel has the potential to prevent nutrients such as phosphorus and nitrogen from making their way into local lakes and waterways. Nordic Dairy Farm’s owner, Clark Hinsdale, explained at a recent press event on his farm: “the best way to capture excess nutrients on farms is to never let them get beyond the boundaries of the farmstead.”
The current anaerobic digestion system “Cow Power,” utilized by Green Mountain Power, functions by using the methane byproduct harvested from constantly produced cow manure to make electricity that then is sold to Green Mountain Power customers. The research done by GSR focuses on another byproduct of digestion – the nutrient dense liquid waste, previously left unused for power purposes.
The oleaginous algae strains that Anju Dahyia has been working with since 2008 thrive on this dense waste and after the algae has consumed the available nutrients, the creation of the distillate fuel can begin. The result makes the process a closed loop system, and means that dairy farmers like Nordic Dairy (whose cows produce up to a ton of manure a day) would be able to sell algae derived biofuel to local fuel dealers and create granular organic fertilizer. According to Dahyia, Hinsdale’s 300 cows alone have the potential to produce anywhere between 20,000 to 30,000 gallons of biofuel each year.
The cost of production is estimated at $20 dollars per gallon, but Dahyia thinks that with increased scale will come a decreased price. At the recent press conference at the Nordic Dairy Farm site early in September, Mary Powell of Green Mountain Power outlined how the company is working with GSR Solutions to help increase scale and add more small refineries that mimic this operation. She went on to note the resiliency a community-sized digester refinery can add to a microgrid.
Speaking to ABC local 22 News, Matt Cota, Director of the Vermont Fuel Dealers Association added, “We know that bio-heat, renewable blended fuel, combined with heating oil works in customers tanks and burners, so if we can source that locally, it would be a great thing for Vermont’s economy, for Vermont famers, Vermont fuel dealers and consumers all across Vermont.”
Richard Altman of the non-profit Commercial Aviation Fuels Initiative was also in attendance and trumpeted that “community-scale digester-refineries in the region might be feasible by 2020,” noting that this project is just a start.
Also on the horizon, GRS Solutions is already working to go further with this technology by incorporating food waste into this digester system. While this system may be in its early stages, one thing is for sure, Vermont energy stakeholders are lining up to show their support and contribute to this more than viable option for local energy production.

David Marchant and Jane Sorensen of River Berry Farm—an organic vegetable and fruit producer in Fairfax—were early adopters of biomass heating when they installed a corn and pellet furnace in one of their greenhouses in 2008. The furnace required manual lighting and was snuffed out often when strong winds blew, and did not produce reasonable heat. “I kept thinking, there has got to be a better option,” recalls David, “It was a real labor burden, and you couldn’t count on it.”
Based on their early experiences and bolstered by a commitment to long-term sustainability and reduced fossil fuel dependence, River Berry Farm opted to host a biomass heating demonstration project. This time, they opted for a higher-rated boiler rather than a furnace. Boilers produce hot water, rather than hot air, which allows more options for distributing the heat. The new system also had an automated propane ignition system.
The biomass heating demonstration was part of a UVM Extension project aimed at trialing several furnaces in agricultural heating applications with funding support provided by the High Meadows Fund. According to Chris Callahan, Ag Engineer with UVM Extension Agricultural Engineering Program who assisted with some of the design and performance assessment, “The main lessons learned from these early installations were to buy high quality fuel, seek improved automatic ignition controls, invest in a good chimney and install it well, and know the actual heat output rating of the unit.”
Modern biomass heating appliances generally include a fuel storage bin, an auger for feeding fuel to the appliance, the appliance itself (boiler or furnace) with an ignition system, a combustion chamber, a heat exchanger, and a heat distribution system. They also incorporate some means of controlling combustion, fuel feed rate, and air flow and often include emissions control measures and automated ash removal.
The selected boiler was a Central Boiler Maxim 250 with a 250,000 BTU/hr input rating, efficiency of 87.8%, and EPA Phase II Hydronic Heater qualification. “The boiler makes hot water which we can use in multiple greenhouses by plumbing it to them in insulated PEX piping. Once in the greenhouse, we convert to hot air with a hot water fan coil, put it in the ground for root-zone heating or on the benches in our mat-heating system for starts,” says Marchant. “I like it. I keep trying to find something wrong with it, but I can’t. The payback period is a bit longer due to higher initial costs, but you have to expect that.”
The basic system cost was approximately $13,000 for the boiler, bin, pad, and plumbing to a hot water fan coil. The other heat distribution systems included in-ground PEX, heat exchange, and plumbing for a bench heat system and added approximately another $5,000. The system is more automated and reliable than the earlier furnace was, but the higher initial costs and the fact that the system is only used 3 months out of the year do prolong the payback period to about 12 years when compared with a propane furnace. If the system was used for 6 (space heating) or even 12 months (wash water, pasteurization) of the year the payback would be halved or quartered, respectively.
“In addition to the financial payback, the carbon emissions avoidance is also of interest to many people,” says Callahan, “In River Berry Farm’s case, the Maxim is helping them avoid 5,910 pounds of net CO2 emissions per year which is about equivalent to 5,000 miles car travel or the CO2 sequestered by half an acre of pine forest.”

Vermont Farmer Helps Others Produce Biofuel
The Vermont Bioenergy Initiative, a program of the Vermont Sustainable Jobs Fund, aims to foster the sustainable bioenergy through a local production for local use model, proven to work for Vermont. Since 2003 the program has allowed Vermont farms to ease their resilience on inconsistently priced, foreign fossil fuels and other agricultural inputs. This is accomplished by focusing on biodiesel production and distribution for heating and transportation, oil crops for on-farm biodiesel and feed, grass energy for heating, and algae production for biofuels and waste management.
Vermont Bioenergy Initiative grantees have shown just how much the addition of biomass feedstock can contribute to sustainable agriculture. As one of these grantees, John Williamson of Stateline Farm would put it, “100 years ago everyone produced their own fuel; we are just doing that now in a different way.” This is really a novel way to look of what he is doing on his North Bennington farm. John was featured in a recent story in Daily Yonder which outlined his work and how he has begun helping his Vermont neighbors find their path to this form of sustainable, renewable energy.
For more about John Williamson’s on-farm biodiesel production, watch this video of John in self-designed Biobarn. He and Chris Callahan of University of Vermont Extension show us how they can grow oil crops, make biodiesel, feed animals, and save money!

Weekly Energy Action Seminars at UVM
Beginning Monday the 14th of September, and reoccurring each week thereafter, an Energy Action Seminar Series aims to explore energy transitions in Vermont, the United States and the rest of the World. Sponsored by the University of Vermont’s Clean Energy Fund, Community Development & Applied Economic program, and the Environmental Program this series will be held from 4:00-05:20 pm in Lafayette Hall Room 108* at the University of Vermont. This series featuring world-class speakers on policy options, political controversy, costs and benefits, activism, and jobs is free and open to the public.
While there is already an extensive line-up of speakers, the most high profile speaker to stand out on the list is former Vice President Al Gore. Gore will draw on his years of climate advocacy for his discourse entitled “The Climate Crisis and The Case for Hope.” When delivering this discourse, Gore aims to address three big questions on the climate crisis: Do we need to change? Can we? And will we? The resounding answer to first two questions of course is a loud YES, but third one most likely cannot be answered in certain terms, and hopefully this where Gore can leave us all with “a case for hope.” NOTE: There is a slight deviation of schedule; this seminar will be on Tuesday, October 6th at 10:15 AM in Ira Allen Chapel.
In addition to Al Gore, numerous other leaders from near and afar will attend and speak during the duration of this series. One such visitor on September 21st, Professor Miranda Schreurs of Free University of Berlin and Director of their Environmental Policy Cente,r stands to bring a plethora of insight from her experience in Germany’s renewable energy revolution. In her time with the Environmental Policy Research Center, Professor Schreurs was on the frontlines of the interdisciplinary collaboration of university researchers necessary for Germany to meet it’s ambitious goal of running almost their entire economy on renewable energy by the year 2050. Germany’s goal is very similar to Vermont’s 2050 goal, and the potential for collaboration and to learn from one another through this event are boundless.
Another great guest speaker will come from Washington, all the way across the US,. Yoram Bauman, more commonly known “Stand-Up Economist,” uses a unique combination of witty comedic talent along with his PhD in Environmental Economics to help an audience explore climate change in an economic context. Yoram’s seminar exploring carbon taxing on October 10th will fall just a couple of days after he serves as the keynote speaker and sits on a carbon pricing panel at the 15th Annual Renewable Energy Conference & Expo in Burlignton, VT. His fresh and recent insight into Vermont’s existing carbon pricing discussion mixed with his existing expertise, and sense of humor will make this event worth not missing.
Additionally, many Vermont energy leaders will be speaking at theses weekly seminars including Representative Tony Klein Chair of House Energy and Natural Resources, Asa Hopkins Director of Planning for the Department of Public Service, Gabrielle Stebbins Director of Renewable Energy Vermont, and Mary Powell of Green Mountain Power. Each of these speakers, as well as the entities they represent, have proven themselves leaders in the Vermont energy landscape through their involvement in recent energy legislation, advocacy, and innovation.

Efficiency Vermont, Renewable Energy Resource Center, Renewable Energy Vermont and Clean Energy Development Fund combine efforts to bring up to $5,500 in rebates to Vermonters who heat local
Through a generous opportunity, Vermonters now have a short-time frame before the new year to capitalize on a fantastic incentive offering that helps them save money, while supporting Vermont jobs and sustainable forests, while making sure they stay warm this winter.
Vermonters can get up to $5,500 to help switch from fossil fuel to local wood heating. Cash incentives are available from the Clean Energy Development Fund and Efficiency Vermont. Renewable Energy Vermont and the Renewable Energy Resource Center have partnered to help promote the incentives.
“We’ve been very happy with our decision to switch to a wood pellet boiler. Not only do we save money every year on our fuel bill, but we also love the fact that we’re helping to keep forests intact and logging jobs going,” says Mark Bushnell of Middlesex.
Vermonters who make the switch to wood pellet fuel typically save $1,500 annually when compared to oil and propane fuel heating options. And for those who are used to whole-home heating through their traditional boiler, the wood pellet boiler keeps it simple and complete. Advanced wood pellet boilers are fully automatic, so there’s no work for the home or business owner.
“I heated my home for years with a standard wood stove, but I’m happier with my wood pellet boiler. The new boiler is much more efficient and better for the environment because it is cleaner burning. And it feels great to be off fossil fuels,” says Susan Clark of Middlesex.
Wood pellet boilers, though not well known in the United States, are the primary way of heating in some parts of the world, including Upper Austria where more than 40,000 homes and businesses heat with wood from their background in an easy, seamless way. In fact, the State of Vermont and Upper Austria are involved in a Sister Statehood Agreement to help learning across both sides of the Atlantic to increase the uptake of this sustainable, local heating option.
“For many years, Vermont has been a national leader in the use of modern wood heating systems in large buildings like schools, office buildings, and apartment buildings. With pellets now available in bulk using specialized delivery trucks that conveniently blow pellets into a fuel bin and heating systems that are fully-automated, many homeowners and small businesses are also making the switch from oil and propane,” said Adam Sherman of the Biomass Energy Resource Center.

Vermont’s solar industry is lauding Governor Peter Shumlin’s proclamation of the third Saturday in June as “Celebrate Solar Day” in Vermont.
The solar proclamation, announced at the Whitcomb Farm in Essex, coincides with this June 20th, when solar projects in communities throughout Vermont will be open for public tours. June 20 is the weekend of the Summer Solstice.
Like open sugarhouse weekend in the spring and open art studio weekend in the fall, the inaugural summertime tours will give Vermonters the opportunity to get an up-close view of solar systems to learn about the technology, solar economics, and the benefits of solar to our community. Solar customers, host farmers, and owners will be on-hand to speak with the public.
More than 50 systems across all regions of the state will be participating in Celebrate Solar Tours and a map of open tours can be found here. Many participating sites will host refreshments, music, or other entertainment. Other planned solar events include community walking tours of residential solar installations, miniature golf, a self-guided bike tour, and on-site yoga.
The Governor’s proclamation notes that “solar energy represented 99% of new electrical capacity in the state in 2014 and more than 5,000 Vermont customers have installed solar” through Vermont’s net metering program.
Further, it cites that the Vermont clean energy industries employ over 15,000 Vermonters, with solar providing “a broad spectrum of employment opportunities, helping retain and attract Vermonters working in manufacturing, installation, and sales, among other careers.”
The Whitcomb family is host to a 2.2 Megawatt solar farm that provides energy for Vermont’s SPEED program.
Among the solar sites open to tour June 20: iconic and sweet Vermont attractions like Cold Hollow Cider and Morse Farm Maple Sugarworks, high-tech attractions like Draker and Small Dog Electronics, agricultural farms like Champlain Orchards, shared community solar arrays, and some of Vermont’s highest producing solar farms.
At the announcement of the solar tours, Paul Brown, owner of Cold Hollow Cider in Waterbury Center, which has a 150kW system powering its operations, said of the event, “Folks know us and visit us for our cider and donuts. But we are thrilled to open up the field behind our cidery to share the benefits of solar technology to our business and our community. We’ll of course also be serving up some sweet treats for those who come by.”
About Celebrate Solar Tours – June 20
The first annual Celebrate Solar Tours on June 20 will feature public tours of more than 50 solar systems of varying size throughout the state. The public will have the opportunity to get an up-close understanding of the technology, economics and benefits to the community. Open systems will be designated with roadway signage and many will feature music, refreshments or other entertainment.

Grass Energy in Vermont
In 2008, the Vermont Bioenergy Initiative began to explore the potential for grasses energy grown in Vermont to meet a portion of the state’s heating demand and reduce the consumption of non-renewable fossil fuels. The Grass Energy in Vermont and the Northeast report was initiated by the Vermont Sustainable Jobs Fund, and carried out by its program the Vermont Bioenergy Initiative, to aid in strategic planning for future grass energy program directives.
Grass Energy in Vermont and the Northeast summarizes current research on the agronomy and usage potential of grass as a biofuel, and points to next steps for the region to fully commercialize this opportunity. The keys to commercializing grass for energy are improving fuel supply with high-yielding crops, establishing best practices for production and use, developing appropriate, high-efficiency combustion technology, and building markets for grass fuel.
Perennial grasses, while serving as a biomass feedstock for heating fuel, also have numerous other benefits to farmers. The grass energy benefits reviewed in the report include retaining energy dollars in the local community, reducing greenhouse gas emissions from heating systems, improving energy security, providing a use for marginal farmland, and reducing pollution in soil and run-off from farms.
Regional and closed loop processing were two models recommended by the report, both involving farmers growing and harvesting grass, but differing in where the grass is processed into fuel and where it is used. The regional processing model calls for aggregating grass from a 50-mile radius at a central processing facility, where the grass is made into and used as fuel, or sold to local users. The closed loop model suggests farmers growing and processing grass on-site for on-farm or community use. Other models, like mobile on-farm processing and processing fuel for the consumer pellet market have significant hurdles to overcome if they are to be successful in Vermont.
In the below video a Vermont agronomist explains switchgrass production followed by entrepreneurs turning bales of grass into briquette fuel. This grass biofuel feedstock can be grown alongside food production on marginal agricultural lands and abandoned pastures, and in conserved open spaces. The harvested grass can be baled and used as-is in straw bale combustion systems, or it can be compressed into several useable forms for pellet fuel combustion systems.
For more information on grass biofuel feedstocks and to read the full Grass Energy in Vermont and the Northeast report visit the grass energy section of the Vermont Bioenergy website.
