Gas-to-liquids (GTL) systems developer Greyrock Energy last month announced the performance results of the testing of the company’s ultrapremium, zero-sulphur diesel fuel.

Greyrock’s fuels are produced from natural gas, natural gas liquids, flare gas and other waste gases using the company’s patented direct fuel production (DFP) systems.

The tests confirmed that Greyrock’s diesel fuel meets existing American Society for Testing and Materials standards, but also has premium properties, including zero sulphur, no aromatics, high cetane and excellent lubricity. Greyrock diesel can also be used as a blendstock to upgrade the quality of petroleum-based diesel fuels.

“When the Greyrock fuel is used in new diesel engines with advanced control systems, reductions in particulates, carbon monoxide, hydrocarbons and nitrogen oxide emissions can be achieved,” says Greyrock CTO Dr Dennis Schuetzle.

“These pollutants can be reduced further when the Greyrock fuel is used in older light-duty and heavy-duty diesel vehicles with less efficient emission control systems, in off-road diesel vehicles, such as tractors and bulldozers, in stationary diesel generators and in diesel-powered vessels.”

In addition, use of Greyrock’s diesel fuels can reduce greenhouse-gas (GHG) emissions. Greyrock’s diesel engine emissions studies have shown that carbon dioxide and methane emissions, both GHGs, are reduced in new diesel vehicles by up to 3.5% and 9%, respectively, compared with petroleum-based diesel fuels.

About Greyrock Energy
Greyrock Energy enables natural gas producers and midstream companies to take full advantage of the industry’s unprecedented levels of shale gas production by transforming natural gas potential worldwide with commercially available, small-scale GTL systems.

Greyrock partners can profit by transforming abundant, low-cost natural gas into higher-value transportation fuels without the costly, large-scale processes larger operators must support using traditional GTL solutions. This revolutionary technology permits more flexible deployment of small-scale GTL processing systems. Founded in 2006 and headquartered in Sacramento, California, in the US, Greyrock Energy’s ground-breaking GTL process converts natural gas into pump-ready transportation fuels.
