[11] Despite the cost of coal dropping in the 1990s, Consol's long-term contracts and investments in longwall mining techniques allowed the company to remain competitive.

Due to uncertainty surrounding demand for coal in the early 2000s, Consol began to place a greater emphasis on diversification, primarily into natural gas.

Consol's first major natural gas investment was through the acquisition of MCN Energy Group Inc.'s methane reserves in southwestern Virginia for $160 million.

Consol also acquired all of the remaining publicly owned shares of CNX Gas for a cash payment of $991 million.

The first, an agreement with Noble Energy was to jointly develop the company's 663,350 Marcellus Shale acres in Pennsylvania and West Virginia.

Officially announced on November 29, 2017, this move marked the start of Consol Energy Inc. operating as an independent, publicly traded company.
