Reducing emissions with safe and effective underground carbon storage


GTI International Deepens Capabilities in Sub-Surface Technologies with the Acquisition of Projeo Corporation

Geologic sequestration of carbon dioxide (CO2), energy storage, and geothermal resources are vital in the transition to low-carbon energy. Storing CO2 below the earth’s surface helps utilities and power producers integrate more renewables, maintain grid stability, minimize the impacts of climate change, and spur the hydrogen economy.

Projeo delivers geotechnical capacity and operational/management services for oil, gas, geothermal, and CO2 storage projects. Each project—and each client—has unique requirements in the nascent field of geologic storage of CO2.

The company has a history of government-funded project leadership, and a growing client list including federal government and commercial contracts with ADM, CarbonSafe, Illinois State Geological Survey (ISGS) at the University of Illinois at Urbana-Champaign, and others. They leverage vast experience and a wide network of industry experts to deliver client‐specific solutions in every facet of the geotechnical value chain for private and public projects.

Projeo is based out of Champaign, Illinois, and is supporting projects in the Illinois Basin and other locations

  • CO2 storage
  • Gas storage
  • Oil and gas production
  • Waste disposal
  • Groundwater resources


Executing first-of-a-kind large-scale CO2 injection into a saline formation in the Illinois Basin‒Decatur Project

Over a decade ago, members of the Projeo team played an important role working with the Illinois State Geological Survey (ISGS) at the University of Illinois at Urbana-Champaign and Archer Daniels Midland (ADM) Company in supporting the Illinois Basin‒Decatur Project (IBDP). Led by the Midwest Geological Sequestration Consortium (MGSC) with funding from the U.S. Department of Energy’s Office of Fossil Energy (DOE-FE), the IBDP project confirmed the ability of the Mt. Simon Sandstone to accept and store one million metric tons of carbon dioxide over a period of three years—the equivalent of annual emissions from about 1.2 million passenger cars according to EPA calculations.

The project well was originally regulated through an Illinois Environmental Protection Agency (EPA) permit as a CO2 injection well for long-term underground CO2 storage, and was later moved to the federal regulatory framework for a Class VI CO2 injection well. The project is the only completed large-scale injection into a saline formation permitted to operate with the U.S. EPA Class VI injection well permit, which creates a pathway for Mt. Simon Sandstone to be used for commercial CO2 storage.

Supporting the ongoing operations of U.S. EPA Class VI CO2 injection wells in the U.S.

Building on the success of the IBDP project, ADM continues to operate the Illinois Industrial Carbon Capture and Storage (ICCS) project through a DOE-FE grant. This long-term project is demonstrating an integrated system of capturing and processing industrial CO2, then transporting it from an ethanol plant in Decatur, Illinois to the Mt. Simon Sandstone formation for permanent geologic storage in deep sandstone.

The project has showcased CO2 compression technology, explored long-term CO2 utilization options, and gathered crucial scientific and engineering data to increase the understanding of large-scale CO2 storage in saline formations. It has also illustrated the economic viability of implementing CCS at biofuels production facilities. Learnings from this project have been applied to ongoing CCS work to drive successful ongoing outcomes.

Since its inception in 2017, Projeo has played an active role in supporting the safe execution of the ICCS project, providing assistance with regulatory modeling, simulation, groundwater monitoring operations, well maintenance, and seismic studies.

Developing CarbonSAFE geologic CO2 storage complexes

Partnering with ISGS and others, Projeo is working on multiple DOE-NETL Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiatives to ensure safe, secure, efficient, and cost-effective CO2 containment in diverse geologic formations throughout the Illinois Basin—including the Illinois East Sub-Basin, the Macon County project, the Wabash Valley Resources project, and the Illinois Storage Corridor project.

Assessments have identified sites and established feasibility of their capability to store more than 50 million metric tons of carbon dioxide (CO2) from industrial sources that can be used for commercial-scale CO2 geological storage as permitted U.S. EPA Class VI CO2 injection well sites.

High-level technical evaluations are providing detailed subsurface characterization and identifying risks. Datasets of formation parameters have been developed and are being used in modeling to examine site performance and long-term security.

The initiatives have demonstrated storage (CCS) technology at real-world, commercial-scale facilities for ammonia production, ethanol production, and coal-fired power generation. Efforts support NETL’s mission to develop and advance CCS technologies for widespread commercial deployment in the 2025 to 2035 timeframe.

Assessing feasibility of subsurface heat storage to generate flexible electricity

A project on geothermal energy furthered the understanding of the feasibility of utilizing abandoned oil and gas wells as geothermal heat storage wells. This DOE-funded project addressed the challenges of energy supply intermittency by storing energy from renewable resources in the subsurface to harvest it at a later time during at-peak energy demand, enhancing grid resilience and reliability. Members of the Projeo team worked through a prestigious Small Business Technology Transfer (STTR) grant and participated in the Energy I-Corps training program to work towards the advancement and commercialization of this novel approach.

In this project, Projeo and its research partners assessed the heat storage and hydrogeological characteristics of subsurface reservoirs to determine the temperature profile and used the baseline data for modeling and simulation to determine other well locations.
