CO2 + Carbon Capture and Sequestration

Carbon capture and sequestration (CCS) is broadly recognized as an important tool for far-reaching and enduring decarbonization, an impressive leap from 1972, which marked the first large-scale project to inject carbon dioxide (CO2) into underground formations. Today, there is broad consensus among experts, engineers, and geologists that it is safe to permanently store CO2 on a large scale. Given the variety of industries that can be re-tooled for CO2 capture, CCS is poised to take another significant step forward.

Tallgrass is advancing a project to convert its Trailblazer natural gas pipeline to a CO2 transportation service, establishing an approximately 400-mile CO2 pipeline to serve as the backbone of a regional CO2 transportation system. This project will allow us to capture, transport and permanently sequester over 10 million tons of CO2 per year from industries in Nebraska, Colorado, and Wyoming. In support of this investment, Tallgrass is developing a commercial-scale CO2 sequestration hub in southeastern Wyoming, partially funded by a grant from the Wyoming Energy Authority.

As part of its overall work in CCS, Tallgrass was awarded funding from the U.S. Department of Energy to study and design commercial-scale carbon capture from a hydrogen-producing facility utilizing a novel autothermal reforming technology. Tallgrass is also pursuing investments in quality vetted carbon offsets for CO2 emissions from both its business administration functions and pipeline operations.
