Electric fracking (or e-fracking) continues to displace traditional fracking in the Marcellus/Utica. What’s the difference between the two? Traditional fracking uses diesel-fueled engines to produce electricity to power pressure pumps for hydraulic fracturing operations. Electric fracking uses natural gas from the well pad to power turbines to create electricity. Electric fracking fleets are roughly half the size of traditional diesel fleets–and a whole lot quieter.
