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.

Vermont-grown grasses are being used to heat the Biomass Building – a 4,200 square foot commercial building at Meach Cove Farms in Shelburne. Local residents, community leaders, and renewable energy enthusiasts are invited to visit Meach Cove Farms Friday, October 23 – Saturday, October 24 for an Open House to learn how grass pellets are generating heat in a biomass boiler – an emerging source of bioenergy in Vermont.
Meach Cove Farms is a 1,000-acre certified organic farm primarily growing soy beans, wheat, rye, and corn as well as wine grapes, woodlands, and switchgrass trial plots for use in grass energy production. The Open House will offer a complete demonstration of the Grass Pellet Heating Equipment Combustion Optimization project – the first project in New England to showcase grass test plots, densification equipment, and an EvoWorld biomass boiler that burns the grass.
Meach Cove Farms began collaborating with Dr. Sidney Bosworth of the University of Vermont College of Agriculture and Life Sciences and the Vermont Bioenergy Initiative in 2009 to assess the potential of different species of grass as solid biofuel for heating applications.
In September 2011 Meach Cove Farms was awarded an USDA Natural Resources Conservation Service Conservation Innovation Grant to research the feasibility of Vermont grown grass pellets and heating equipment potential as an emerging renewable energy source in Vermont. The biomass boiler being featured at the Open House was funded through a Conservation Innovation Grant (CIG) administered by the Natural Resources Conservation Services.
IF YOU GO:
Meach Cove Farms is located at 310 Beach Road in Shelburne (off Bostwick Road, 1.6 miles west of Rte 7). The Open House runs from 9 am – 12 noon both Friday and Saturday, October 23-24. There is no cost and both days are open to the public. More info at www.meachcovefarms.org, 802-985-9218.
On October 6th, Seventh Generation and the University of Vermont welcomed the 45th US Vice President, Al Gore at Ira Allen Chapel on the university’s campus. The highly anticipated speaking engagement entitled “The Climate Crisis and the Case for Hope,” which is part of an Energy Action Seminar Series facilitated by UVM Energy Alternatives, was truly an emotional roller coaster and had Gore left the stage at the halfway mark, all in attendance would have gone home rather depressed. “We are going to win this struggle” he stated, “the question is how quickly we will win,” Gore remarked before elaborating on the deep sinkhole humanity has fallen into.
The lecture followed a path most familiar with the former vice president’s advocacy would expect. The rising atmospheric greenhouse gas (GHG) levels that we are witnessing come from a variety of sources, but as Gore pointed out “the main problem is burning of fossil fuels, when we address this, the rest will fall into place.” The first part of the lecture really focused on the crisis. The audience watched in horror footage of major weather events, many have seen before, but taken in all at once really underline the major recent changes that we have seen in our global weather patterns. Gore noted that of the “14 of the hottest years on record have been in the last 15 years,” and that the average temperature at night during this time has increased, meaning that people and the planet, really can’t get a break from the heat.
Gore went on to talk about the cost of carbon, or as he tried to drive home, the lack of cost it represents to our economy. “We need to put a cost on carbon,” he noted “put a cost on denial” he then continued in reference to those who deny climate change. This statement was met by large applause by those who filled Ira Allen Chapel, hitting home for a crowd that will likely be talking a lot about carbon pricing in the upcoming legislative session. Political instability, floods and mudslides, wildfires, drought, storm damage, dying coral, infrastructure loss, species extinction, melting glaciers, famine water security, ecosystem loss, our way of life, infectious disease, and sea level rise all represent the cost of carbon we are already paying Gore noted on a slide with an animated cash register racking up the cost, concluding “there is a financial risk to using fossil fuels”
It’s worth noting, that this notion does not make Gore an outlier anymore. Just last week the Governor of the bank of England, Mark Carney echoed the same message when he spoke on the increase of major weather events and the related financial cost at meeting of leading insurers at Lloyd’s of London. Additionally, going back to last year, the department of defense listed climate change as an agitating factor in areas already experiencing political instability.
As was said earlier, if Gore had sent everyone home after the “The Climate Crisis” part of his lecture, without the “Case for Hope” portion, everyone there would have a pretty doomy and gloomy demeanor for weeks to come. Instead, the mood took a 360 change with Gore trumpeting the triumphs of the past year that have put humanity on a course towards beating climate change. Among these he gave Burlington credit for achieving 100% renewable energy. He went on the new power generated in 2014 three quarters of it was renewable energy, and reflecting on the fact that those who still deny climate change can agree, renewables just make economic sense.
To close, Gore instructed the audience, “always remember, that political will is a renewable resource.” As Vermont and the rest of the nation watch national and local campaigns for political office start up in which politicians’ attention, or potential lack of attention, can greatly shape our climates future, let’s hope that holds true. Leaving Ira Allen Chapel, one couldn’t help but feel a sense of optimism, and optimism is definitely a renewable resource.

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.”

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!

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.

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.

The Summit on Creating Prosperity and Opportunity Confronting Climate Change brought together over 400 innovative business, non‐profit, and community leaders, elected officials, public policy advocates, students, and interested residents to begin to frame policy and investment strategies to advance the development of the Vermont Climate Economy. Summit participants developed a list of key practical actions to serve as a launching point for the Vermont Climate Change Economy Council (VCCEC), a group charged with a one year mission to develop a structured plan with practical actions to reduce carbon emissions and stimulate green economic development in Vermont. The Council will build a set of public/private strategies designed to promote economic opportunity, innovative business development, investment, and job creation in Vermont.
Over the course of 2015, VCCEC will evaluate findings, key ideas and suggested action steps derived from the Summit, lead regional public forums, evaluate and summarize research findings, interview key stakeholder groups, and consider model economic development strategies from other state and countries. During 2015, the group will develop a strategic platform of recommendations for action, and report to the Vermont legislature, the Governor of Vermont and the public in January 2016. The Vermont Council on Rural Development (VCRD) will provide support to their work and then help promote the platform of action that comes from its deliberants. Goals of the Vermont Climate Change Economy Council are to:
- Identify opportunities created by climate change to strengthen Vermont’s economy through strategies advancing key business clusters and economic sectors.
- Build an increased sense of unity in Vermont around policies to confront and mitigate the impact of climate change and to advance economic opportunities and solutions that respond to climate change.
- Build a public information campaign to celebrate innovation and Vermont’s green business leadership; internally and externally marketing to build the Vermont brand as an economic/environmental problem solver.
- Expand Vermont’s economic brand around climate change solutions to retain and attract youth and creative entrepreneurs to locate throughout the state.
Vermont businesses and nonprofits are addressing climate change – both its challenges and opportunities. Their creative solutions are a growing part of our state’s economy. What are your experiences? Do you have ideas about how Vermont can grow jobs and nurture innovative business development in sectors ranging from clean energy, to recycling, transportation systems, and thermal efficiency?

Mark Mordasky, owner of Rainbow Valley Farm in Orwell, Vermont has been growing soybeans as a cash crop and for on-farm biodiesel and animal feed since 2008. When fuel prices began to climb, Mark took initiative and started searching for an innovative and more cost efficient way to meet his farm’s energy demands. The Vermont Sustainable Jobs Fund was able to help Mark take his first steps towards sustainable biofuel production. Mark is able to press these soybeans after harvesting and make two distinct products, oil and meal. The meal is an instantly marketable product and can be sold as feedstock or organic fertilizer; the oil will be further processed into biodiesel.
Soybeans crops are well suited for biodiesel production in Vermont and perform best in heavy soil like those found in Addison County, as University of Vermont Extension Agronomist, Heather Darby explains. Soybeans don’t always do well in in light, well drained soils, and as with any crop the best way to understand the demands of any crops is to contact your University Extension and have your soil tested. Additionally, because soybeans are a legume, they produce nitrogen in association with bacteria, meaning that these crops don’t require the application of additional nitrogen to produce a high yield. These low input, high yield crops are fairly easy to grow, are well suited to the Vermont climate, and afford farmers flexible planting dates. Heather and the rest of the UVM Extension team have seen yields ranging from 35 bushels per acre to up to 85 bushels per acre with varying practices.
In the below video, Mike Mordasky shares his experience and knowledge of soybean production from planting through harvesting harvest and beyond to storage and the creation of the final products. In addition, Heather Darby shares here insights into maturity groupings, variety selection, and best growing practices.
