‘Complete System to Capture, Store, Transport and Utilize,’
Bio-ANG for Powering NGVs Remains ‘A Work in Progress’
Cenergy Solutions is offering its ANG/adsorbent natural gas as a way “to help farms, communities and businesses around the world store and use their biogas, reducing venting and flaring methane.”
ANG technology allows natural gas to be stored at far lower pressures than those necessary for CNG/compressed natural gas, lowering the cost of containers and allowing for non-cylindrical fuel tanks.
Cenergy is now offering to help pare the global waste of methane-rich biogas with “a complete ANG system to capture, store, transport and utilize biomethane worldwide.”
Putting Local Wasted Energy to Work
The company cites estimates that a trillion cubic meters of natural gas and 1.6 trillion cubic meters of biogas from oil wells and biogas digesters are vented or burned worldwide each year, not including the biogas that goes uncaptured.
“Methane, thought to be 25 times more harmful to the atmosphere than carbon dioxide, is being released at an alarming rate because it is too expensive to compress to high pressures for storage and transport,” the company says.
“Cenergy Solutions’ low-pressure adsorbent natural gas and biogas technology can economically capture, store, transport and utilize this wasted energy in vehicles, for cooking, heating and to power manufacturing and power plants.”
Cenergy is offering a package with a Canadian Standards Association/CSA-certified compressor and DoT-compliant Type 1 tanks to store and distribute biomethane. An optional buffer tank can hold excess biomethane for later use.
“With this unique system you can fill multiple ANG tanks at the same time exchanging the full tanks with empty tanks as needed with Cenergy’s quick connect nozzle and coupler,” the company says. “The low-pressure system “makes it easy, safe and economical to store and distribute biomethane around the world.”
“Throughout the world most countries rely heavily on LPG (propane, aka propane autogas) to supply their citizens the energy they need to cook, heat and fuel generators,” Cenergy COO Gary Fanger said in a release.
A First Licensee in India
Now countries have the option to supply their population with biomethane that is made on their farms, landfills and wastewater treatment plants,” he said.
Cenergy says it’s signed a first licensing agreement with operators of a biogas plant in India. The facility which currently produces more than two tons of methane per day and is increasing fivefold. “Using ANG tanks filled with biomethane will be a significant savings for the biogas plant and the customers they serve.”
Carbon Dioxide Removal Pending
Regarding purity, “We have several systems that remove hydrogen sulfide and moisture,” Fanger told F&F by email yesterday. Removing carbon dioxide to make the gas suitable for vehicles use “is harder and more expensive.
“A work in progress,” he says.
