Hog Waste Is Becoming A Streamlined Fuel Source
buy canada goose jacket cheap In late March, a project in eastern North Carolina revealed the potential to turn every hog farm canada goose premium outlet in the state into canada goose outlet 2015 a source of renewable natural gas, or what’s known as swine biogas. buy canada goose jacket cheap
canada goose factory sale Biogas typically refers to methane created by the canada goose outlet vancouver breakdown of organic matter. It can be made from food scraps, decomposing plants and animal waste. Swine biogas is methane that comes from hog waste. canada goose factory sale
canada goose uk outlet Most people think the purpose of biogas canada goose womens outlet is to create green canada goose factory outlet vancouver fuel, but that’s actually the byproduct. The main purpose of creating biogas is to destroy methane and earn valuable carbon offset credits methane is a greenhouse gas that is 25 times more potent than carbon dioxide. canada goose uk outlet
The Optima KV Project has the potential to do both destroy methane and create enough renewable natural gas to power the equivalent of 1,000 homes for a year.

The canada goose outlet store near me Optima KV Project does for swine biogas what Henry Ford did for the auto industry. It streamlines production by getting rid of individual microturbines at each farm. Instead, it funnels the biogas from five Duplin County hog farms into a pipeline that feeds into a nearby Duke Energy power plant. This is what’s known in the industry as “directed biogas.”
Canada Goose Parka “I just think that makes a lot more sense,” said Randy Wheeless, a spokesman for Duke Energy. “That’s because the process of turning the gas into electricity will happen at a major power plant with higher efficiency and better emission controls.” Canada Goose Parka
Canada canada goose jacket outlet sale Goose online Duke Energy is purchasing the Optima project’s swine biogas to meet a state required mandate that 0.2 percent of energy canada goose parka outlet uk come from hog waste by 2023. This project is getting canada goose outlet in chicago the state close to meeting that mandate for the first time. Canada Goose online
canadian goose jacket Another biowaste production facility, the Carbon Cycle Project, was slated to come online this summer, but people familiar with the company say it’s been delayed. The Denver based company, Carbon Cycle Energy, expects its project in Duplin County will produce canada goose outlet england enough electricity to power 32,000 homes annually. About a quarter of that energy will come from swine waste. canadian goose jacket

canada goose coats A 2013 Duke University study found the directed biogas approach could lower the cost of swine biogas to as little as 5 cents a kilowatt hour, which is roughly the same price as solar power. canada goose coats
canada goose uk black friday And there’s a reason Duke University is interested canada goose stockists uk in lowering the price of renewable natural gas. It canada goose outlet in vancouver has a goal of bringing all its emissions to zero buy canada goose uk by 2024. And while solar and wind energy can get Duke most of the way there, it’s not enough. canada goose uk black friday
canada goose clearance The university still needs a combustible fuel source to turn water into steam in its massive boiler plant. That steam creates heat for buildings on campus year round. The plan is to convert the boilers from burning natural gas to burning swine biogas. canada goose clearance
Canada Goose sale “That means we would be able to run the campus on a renewable energy source,” said Tanja Vujic, director of biogas strategy at Duke University. “And we would get credit for destroying methane that’s coming off those lagoons.” Canada Goose sale
uk canada goose In 2010, Duke University partnered with Google to pilot a system for turning hog excrement into electricity. This system https://www.canadagoosesale.info is still running at Loyd Ray Farm in Yadkinville, hundreds of miles west of where most of the state’s hogs live. uk canada goose
cheap canada goose uk The purpose of the system was for Duke and Google to earn carbon credits to canada goose outlet black friday sale offset their carbon footprint as they transition to more renewable energy sources. The two could have gotten credits for capturing the methane and burning it (known as flaring), but Duke saw potential for swine biogas in a state with roughly 9 million hogs each producing 10 times as much waste as a human. cheap canada goose uk
Canada Goose Outlet Turning Pig Poop Into Green Energy Canada Goose Outlet
Canada Goose Coats On Sale Creating biogas from hog waste is a relatively simple concept. On any hog farm, water is used to flush waste out of the barns into a lagoon. Bacteria eats that poop and creates methane. Instead of letting that methane bubble into the atmosphere and add to climate change, you can capture it by covering the lagoon with what looks like canada goose outlet winnipeg a giant pool cover.

uk canada goose outlet “A big storage balloon is what it amounts to,” said Marvin Cavanaugh, owner of the Winston Salem based engineering firm Cavanaugh. Duke hired the firm to develop the pilot project at Loyd Ray and test the potential for scaling swine biogas to an industrial level. uk canada goose outlet
At Loyd Ray, Cavanaugh also uses a giant pump at the bottom of the lagoon to circulate the liquid waste. This ensures air, bacteria and pig poop are all maintained at the canada goose outlet edmonton right balance.
canada goose black friday sale “It’s pretty similar to a compost pile,” Cavanaugh said. “You have to maintain the right mix and temperature.” canada goose black friday sale
canada goose uk shop The resulting methane is then cleaned and turned into pressurized natural gas that can be turned into electricity. This fuel Canada Goose Outlet is highly versatile and can be used in myriad ways. Some farmers use it to run diesel generators. canada goose uk shop
cheap Canada Goose There hasn’t been much demand for canada goose outlet woodbury the fuel because gasoline is a cheaper option for cars and natural gas is a cheaper option for buildings. But as canada goose outlet new york more companies and countries move away from fossil fuels and make zero emission pledges, this renewable natural gas is starting to become a lot more attractive. cheap Canada Goose
Canada Goose Jackets “We had two teams from China come. I asked what they were gonna do with it,” Cavanaugh said. “He said ‘We’re gonna bottle it and burn it in canada goose outlet seattle our cars.’ I said ‘It’s not cost effective.’ He said, ‘Maybe not for you, what you pay for gas. But what we pay for gas, it’s very effective.’” canada goose parka outlet Canada Goose Jackets
Canada Goose Online Over the past seven years, the project at Loyd Ray Farms has taught Cavanaugh and Duke University how to scale the production process and squeeze more gas from each hog farm, as they eye the vast untapped canada goose outlet mall waste lagoons in the eastern part of the state.

canada goose Moving forward, Duke researchers are hoping the university’s role as a large, stable purchaser of biogas will be the catalyst for creating a stable market for the green fuel. They estimate it canada goose outlet montreal could drive as many as 300 hog farmers into producing biogas by creating steady demand for the fuel canada goose.
