A new power facility is expected to open in southwest Phoenix in December. It will collect methane from cow manure and use biogas as a renewable fuel Reuse of natural fuels. Stakeholders at Facility
told the Arizona Republic that the process will capture harmful gases that would otherwise escape into the atmosphere and exacerbate climate change.
The project is a partnership between Avolta, a renewable energy company in West Virginia, and Butterfield Dairy Farm in Buckeye.
Southwest Gas Holdings Inc. will help transport natural gas to other outlets.
Some renewable natural gas facilities have sprung up in the Southwest in recent months, including Arizona and California. The Avolta facility
is one of at least five renewable natural gas plants in or about to enter Arizona. According to the “Repubblica” report, others are expected to open in Tucson, Girabend and Maricopa.
Unlike the Arizona power company, the Arizona power company must obtain 15% of its energy from renewable sources by 2025. According to the report, Southwest Natural Gas does not have such a required standard.
Despite this, the natural gas utility still cooperates with five facilities in Arizona and California. The spokesperson told the Republic that the utility company is committed to cooperating with more renewable natural gas developers. The five partners of
Southwest Gas will generate approximately 10 million calories of energy, while Butterfield Dairy LLC will generate 3 million calories.
energy will represent a small portion of the total energy produced in the state. According to The Republic,
Southwest Gas generated 800 million heat last year.
Avolta officials stated that Butterfield Dairy’s emissions reductions are equivalent to reducing 3,500 cars on the road each year. Together with the upcoming Maricopa facility, the emissions reduction will be equivalent to reducing the number of cars on the road by 8,000.
Approximately 10 million gallons (38 million liters) of cow manure will be stored in a sealed underground container at the Avolta base for approximately 22 days while undergoing an “anaerobic digestion” process to produce biogas.
According to the Environmental Protection Agency, the process takes place in a container without oxygen and bacteria break down the waste into reusable products. The excrement of 4,444 Butterfield dairy cows will be turned into biogas, composed primarily of methane and carbon dioxide, and digested, the remaining manure from which most of the methane and carbon dioxide have been removed.
This container is about the size of 10 Olympic-size swimming pools, larger than two football fields, and will handle 55,000 tons (50 million kilograms) of manure each year. Republic
stated that the biogas at the end of the process will be “regulated and upgraded” to renewable natural gas by a natural gas technology company in West Virginia.
