LNG for Rocks – and Rock Trucks?

Quarries Like Omya’s in Vermont Could Boost Demand

Quarries and sand pits need fuel for their dryer furnaces, and a switch from diesel fuel oil to liquefied natural gas for them could ease the way for the same operations to fuel their hard-working trucks with LNG too. That’s the word from Houston this week, where Zeus Development is hosting the World LNG Fuels through Wednesday noon. Michael Laurent of Switzerland-based Omya explained how his company is modifying its furnaces in Vermont for marble drying for natural gas dual fuel operation, and is interested in the cheaper cleaner fuel for its trucks as well.

Omya plans to install eight 15,000-gallon LNG storage tanks at its facility in Florence, Vt. as part of a $7 million to $10 million project to shift its furnaces to LNG-diesel dual fuels. LNG could support the firm’s 20 heavy duty trucks in Vermont too.

Zeus Development chief Bob Nimocks said that facilities like Omya’s consume some 60 million gallons of fuel per day in the U.S. “This is conceivably a very large market,” he said.

“We consume more than 3 million gallons of fuel oil a year for our drying operations,” Laurent said.

Omya said last year that it would begin the process of using LNG fuel, installing eight 15,000-gallon LNG storage tanks at its facility in Florence, Vt. as part of a $7 million to $10 million project. “We have determined that natural gas is the optimal fuel source for our needs and will replace our current use of No. 2 Fuel Oil,” the company said.

Wanted in Vermont: LNG

Omya is in the final month of detailed design work, Laurent said in Houston. The company expects to start using natural gas later this year.

By changing over to LNG dual fuel, “We’re looking at approximately 50% savings,” he said. Dual fuel allows a fall-back if LNG is not available. “We’re 24/7,” Laurent said. “We can’t run out of fuel.”

Laurent said too that a source of supply has yet to be determined. The import terminal at Everett, Mass. is a leading candidate.

Omya’s 20 heavy duty trucks serving its three Vermont quarries log about 6,000 miles per day. The mixed fleet, uses about 300,000 gallons per year, Laurent said in Houston. He’d like to run the trucks on natural gas too. The current fleet is mostly Mack, with some Kenworth and Western Star units, all pre-2007 with approximately 450- horsepower, he told F&F.

“We are exploring both new and retrofit options with multiple suppliers,” he says.
