Honeywell UOP technologies have been selected to capture and sequester up to 1.65 million tonnes of carbon dioxide (CO2) annually and produce clean hydrogen energy from a repurposed gasification plant in West Terre Haute, Indiana.

Wabash Valley Resources selected the technology for the project which is expected to be one of largest carbon sequestration initiatives in the US to date.

Under the contact, UOP will provide technology licenses, basic engineering, and specialty equipment including a modular MOLSIV™ molecular sieve dehydration unit, modular Ortloff CO2 Fractionation unit, and Polybed™ pressure swing adsorption (PSA) unit to sequester CO2 and process synthesis gas from the gasification unit.

The Ortloff CO2 Fractionation technology will produce a high-purity liquid CO2 stream while separating a hydrogen-rich stream that will be purified by the PSA unit. The CO2 stream will be sent for permanent geological storage, while the hydrogen stream can fuel a hydrogen turbine to generate electrical power. The hydrogen stream can also be used in chemical synthesis or marketed as a clean transportation fuel.

Dan Williams, Managing Director of Wabash Valley Resources, said, “By implementing Honeywell UOP’s proven technologies for the capture of CO2 and hydrogen purification, we will significantly reduce greenhouse gas emissions.”

“This project will allow for market access to clean hydrogen, as well as support the domestic growth of the hydrogen economy.”

Laura Leonard, Vice-President and General Manager, UOP Process Technologies, said, “Adding carbon capture and storage to hydrogen production is an economical solution for many companies looking to make significant progress on their sustainability goals.”

“Hydrogen is a versatile energy carrier that can provide a low-carbon solution across almost every industry—petrochemical and refining, buildings, commercial, transportation and power generation. Customers like Wabash trust Honeywell UOP to provide optimized technology solutions to meet project requirements.”
