Linde Says Early Results from LNG/Diesel Generators Promising
Drilling rigs for shale gas use a lot of electricity to power the equipment—so much electricity each drill site uses enough generators to power an entire town. Drillers make their own electricity rather than draw from the local power grid. Almost all electrical generators at well sites are powered by diesel engines. But a few enterprising companies are offering alternatives to diesel. Hey, why not use natural gas to power those engines, since you’re drilling for natural gas!
Linde North America is one of those enterprising companies. CONSOL Energy’s gas division is experimenting with a dual-fuel technology that combines liquefied natural gas (LNG) with diesel, blending them together, a technology being pioneered by Linde. CONSOL is currently testing it with three generators in the Marcellus, and according to Linde and CONSOL, the early results are promising.

The Obama EPA has bungled a lot—chief among their bungles was their attempt to prove a connection between fracking and water contamination in Pavillion, Wyoming. The EPA hoped that Pavillion would be the smoking gun—the single, solitary case (any case!) they could use as an excuse to (illegally) start regulating oil and gas drilling through the back door of the federal Safe Drinking Water Act. But something happened on the way to the “we’ll take over regulating fracking from the states” ball: The wells the EPA used for their data in Pavillion were drilled by the EPA and the high levels of chemicals in the wells may have come from their own botched drilling job. Oops—maybe they ought to leave drilling to the experts. Lots of backpedaling ensued (
