Turboden waste heat-to-power plant in operation at an O&G facility in Canada (click for larger version)
Tallgrass Energy is the majority owner of the Rockies East Express (REX) pipeline — a 1,712-mile pipeline that runs from Colorado and Wyoming to Ohio. REX was built to bring then-abundant natural gas from the West to markets in the Midwest (such as Chicago) and the East via connections to other pipelines. Then, the Marcellus and Utica happened, forever changing the natural gas landscape in the United States. Nobody in the Midwest and East wanted Western gas anymore. So in 2015, Tallgrass reversed the flow for a portion of REX, from Monroe County, OH to Mexico, MO (see 1.8 Bcf/d of Marcellus/Utica Gas Heads West on REX Starting Aug 1). Three of the compressor stations along REX's eastern Zone 3 (that flow Marcellus/Utica molecules) will be fitted with technology to turn waste heat into electricity.
