Basalt Fiber Instead of Carbon and There Is No Liner

A new technology from Oklahoma could shake up the already hard-charging American natural gas vehicles sector, as Tulsa startup CleanNG commences tests this week of a radical new compressed natural gas fuel cylinder.

Tulsa-based CleanNG’s MagmaCel brand CNG tanks feature a liner-less design and basalt fiber and, the company says, will be dramatically lighter than current products and cost-competitive with existing Type IIIs and Type IVs.

CleanNG’s liner-less design means more gas in a comparable exterior size, with basalt fiber instead of conventional carbon fiber. “We’ve made it all one complete structure,” says chief operations officer Michael Tate.

The firm is winding its first 10-by-40-inch tanks, which according to Tate will have an internal volume of 47.2 liters and will hold just shy of 4 gasoline gallon equivalents of CNG at 3,600 psi – while weighing less than 12 pounds. A 5,800-psi version holding 5.15 GGE – a 30% increase – will weigh just 15 pounds, he says.

CleanNG CEO and MagmaCel basalt fiber CNG cylinder inventor Matt Villarreal at work on an early 10-by-40-inch tank on Tuesday.

Four articles are being prepared this week to be sent to Authorized Testing, Inc. in Riverside, Calif. for certification trials, Tate told F&F.

Next up is a 24-by-60-inch version.

“We should have the two models DoT-tested by the end of this year,” he says.

CleanNG expects its selling price to be competitive with existing products. “We should be on a par with carbon fiber,” Tate says.
