Kinston, NC - Many homes in Eastern North Carolina may now be powered by an alternative source of energy that uses a mixture of natural gas and swine-derived biogas.

A switch thrown last week by Duke Energy infused methane captured from Duplin County hog lagoons into a natural gas pipeline.

Optima KV is the project developer and has partnered with Duke Energy to supply the energy and Smithfield Foods to donate the land for a facility to collect the hog methane. Once collected, the gas is cleaned and injected into the natural gas pipeline to serve two Duke Energy plants in Eastern North Carolina.

The project is expected to generate about 11,000 megawatts-hours of renewable energy annually, enough to power about 880 homes for a year, according to the N.C. Pork Council. | For the full story, CLICK HERE.

Marin County, Calif. - On one organic dairy farm, the feed truck runs on cow power.

"I was able to put together a fully electric truck to feed the cows that's powered by the cow's waste. We claim that's the first one in the world to do that," says Albert Straus, CEO of Straus Family Creamery in Marin County, California.

When cow manure breaks down, it releases methane, a potent global warming gas. But that methane can be captured and used to make electricity. Using technology called a methane digester, Strauss has been converting his cow's manure into energy for the last 14 years. The process produces enough electricity to power the whole farm. And now, that energy is also being used to charge his electric truck. | For the full story, CLICK HERE

Farm manure could be a viable source of renewable energy to help reduce greenhouse gas emissions that cause global warming.

Researchers at the University of Waterloo are developing technology to produce renewable natural gas from manure so it can be added to the existing energy supply system for heating homes and powering industries. That would eliminate particularly harmful gases released by naturally decomposing manure when it is spread on farm fields as fertilizer and partially replace fossil natural gas, a significant contributor to global warming.

"There are multiple ways we can benefit from this single approach," said David Simakov, a professor of chemical engineering at Waterloo. "The potential is huge."

Simakov said the technology could be viable with several kinds of manure, particularly cow and pig manure, as well as at landfill sites.

In addition to being used by industries and in homes, renewable natural gas could replace diesel fuel for trucks in the transportation sector, a major source of greenhouse gas emissions.

To test the concept, researchers built a computer model of an actual 2,000-head dairy farm in Ontario that collects manure and converts it into biogas in anaerobic digesters. Some of that biogas is already used to produce electricity by burning it in generators, reducing the environmental impact of manure while also yielding about 30 to 40 percent of its energy potential.

Researchers want to take those benefits a significant step further by upgrading, or converting, biogas from manure into renewable natural gas. That would involve mixing it with hydrogen, then running it through a catalytic converter. A chemical reaction in the converter would produce methane from carbon dioxide in the biogas.

Known as methanation, the process would require electricity to produce hydrogen, but that power could be generated on-site by renewable wind or solar systems, or taken from the electrical grid at times of low demand. The net result would be renewable natural gas that yields almost all of manure's energy potential and also efficiently stores electricity, but has only a fraction of the greenhouse gas impact of manure used as fertilizer.

"This is how we can make the transition from fossil-based energy to renewable energy using existing infrastructure, which is a tremendous advantage," said Simakov, who collaborates with fellow chemical engineering professor Michael Fowler.

The modelling study showed that a $5-million investment in a methanation system at the Ontario farm would, with government price subsidies for renewable natural gas, have about a five-year payback period.

A paper on modelling of a renewable natural gas generation facility at the Ontario farm, which also involved a post-doctoral researcher and several Waterloo students, was recently published in the International Journal of Energy Research.

March 2, 2018, Wooster, OH — A rural community in northcentral Ohio is divided over plans to build a 10 million gallon waste lagoon on a farm north of Wooster.

Quasar Energy, which operates the anaerobic digester on the campus of the Ohio Agricultural Research and Development Center in Wooster, plans to construct the storage pond. The earthen-lined lagoon would hold both anaerobically digested biosolids and up to 300,000 gallons of hog manure annually from the landowner’s hog farm, according to the permit application.

Supporters say it will provide a source of organic fertilizer. Opponents fear it could lead to issues with groundwater contamination, odor and traffic. READ MORE

February 8, 2018, Sacramento, CA – Renewable Dairy Fuels (RDF), a business unit of Amp Americas, recently announced that construction is underway on the country’s largest on-farm anaerobic digester-to- vehicle fuel operation.

Located in Fair Oaks, Indiana, the dairy project will be the company’s second biogas facility producing renewable natural gas from dairy waste for transportation fuel.

Amp Americas received the first dairy waste-to-vehicle fuel pathway certified by California's Air Resources Board (CARB) for its first RNG project at Fair Oaks Farms in northwest Indiana. The project was also awarded a Carbon Intensity (CI) score of -254.94 gCO2e/MJ, the lowest ever issued by CARB.

In addition to generating renewable American energy, on-farm anaerobic digester operations improve sustainability, environmental stewardship and energy independence.

The new facility will be 50 percent larger than RDF’s operation at Fair Oaks Farms and will be operational this summer. The site is located in Jasper County, IN, just a few miles from Fair Oaks Farms.

Every day, three digesters located at three dairy farms will convert 950 tons of dairy waste from 16,000 head of milking cows into 100 percent renewable transportation fuel. The RNG will then be injected into the NIPSCO pipeline.

Each of the digesters is a DVO, Inc. designed and built Mixed Plug Flow digester.

“Transportation is now the largest source of greenhouse gases in the U.S., and a major source of smog-causing pollution,” said Grant Zimmerman, CEO at Amp Americas. “It is more important than ever to drive further adoption of clean and efficient domestic RNG within the trucking industry. There isn’t enough RNG being produced to meet customer demand. Our new project will help make strong headway toward closing the supply gap.”

Amp Americas continues to expand its national footprint and to invest heavily in dairy RNG projects by partnering with dairy farmers across the country to bring more ultra-low CI gas to market. The company plans to more than double its dairy gas output by mid-2018, and aims to deliver Amp Renew, its 100 percent RNG product, to all 20 of its fueling stations as it brings on future projects.

January 23, 2018, Portland, OR – Climate Trust Capital, a U.S.-based private investment fund, has closed on a carbon investment in the biogas sector –the Carlos Echeverria and Sons Dairy (CE&S) biogas project.

Approximately $1.12 million of Climate Trust Capital’s Fund I was invested in a covered lagoon digester that will destroy methane and produce carbon offsets under California’s cap and trade system.

The investment is based on the anticipated 10-year value of carbon credits from a livestock digester project located at the Carlos Echeverria and Sons Dairy, a large farm in California’s Central Valley. Project partner, California Bioenergy LLC (CalBio), has built three other dairy digester projects, including California’s largest, with three additional projects currently coming on line and many more scheduled for development. This project investment is expected to begin generating carbon offsets in January 2018 with initial cash flow from the sale of these offsets in 2019.

“Generating revenue from the sale of offsets through California’s cap and trade program is a complex process requiring a great deal of regulatory oversight to ensure the credits are real, additional, and permanent,” said Andrew Craig, director of greenhouse gas reduction initiatives for California Bioenergy. “We’re thankful to have partnered with some of the leading experts in the dairy digester industry, including The Climate Trust, who has been an invaluable asset to us and our dairy farmer partners.”

“The need for capital when building a livestock digester project is in strong alignment with Climate Trust Capital’s investment thesis of providing an early-stage investment to catalyze projects,” said Kristen Kleiman, director of investments for The Climate Trust. “Digesters improve the economic and environmental performance of dairies, provide clean energy, improve soil nutrient management, improve local air quality, and so much more. Quality digester projects will make up a sizeable portion of our investment portfolio, enabling the trust to keep an eye toward ensuring the best possible premiums from the sale of generated credits.”

The CE&S digester will treat the manure by covering manure lagoons with a flexible, high-density polyethylene cover. Captured methane will be stored and then combusted in a high-efficiency generator that delivers renewable electricity to Pacific Gas and Electric. In addition, the digester will be double lined and enhance ground-water protection. Effluent from the digester will be used to irrigate fields.

December 20, 2017, San Francisco, CA – The California Public Utilities Commission (CPUC) recently established a new program to reduce emissions of methane, a potent short-lived climate pollutant, from manure generated at dairies.

The pilot program will incentivize at least five projects where dairy digesters capture and process the biomethane gas from manure to produce renewable natural gas.

The program was adopted pursuant to Senate Bill (SB) 1383 (Lara, 2016) which authorizes funding of the dairy biomethane pilot projects to demonstrate interconnection to the gas pipeline system. The pipeline infrastructure is needed to inject renewable natural gas (after a conditioning process) into the utilities’ natural gas distribution system, where it may be sold to customers. SB 1383 established a goal of 40 percent reduction of methane emissions statewide by 2030. Emissions from manure represent approximately 26 percent of California’s methane emissions.

“This program helps turn a waste product into renewable energy,” said Commissioner Clifford Rechtschaffen. “In addition to reducing emissions of methane, the pilot projects will help improve air and water quality in the Central Valley and other regions. Strong interagency coordination has allowed us to implement this in a very short timeframe.”

Under the proposal, an interagency committee that includes the CPUC, the California Air Resources Board, and the California Department of Food and Agriculture will select the pilot projects. The committee will choose projects based on an evaluation of the proposed business model, likely greenhouse gas reductions realized and cost effectiveness of achieving these reductions, environmental benefits, disadvantaged community benefits, and project readiness.
