Project Description

Linde Inc., in coordination with Linde Engineering Americas, Linde Engineering Dresden, and Svante Inc., will complete an initial engineering design of a commercial-scale carbon capture plant using the Svante VeloxoTherm™ solid adsorbent carbon dioxide (CO2) capture technology to be installed at an existing Linde-owned steam methane reforming (SMR) hydrogen (H2) production plant in Port Arthur, Texas. The overall system will be designed to capture approximately 1,000,000 tonnes/year net CO2 with at least 90% carbon capture efficiency while producing “blue” H2 with 99.97% purity from natural gas. The engineering design will comprise of the core technology; process units inside the battery limits (ISBL) of the CO2 capture unit, such as flue gas conditioning and CO2 product purification; and balance of plant components outside the battery limits (OSBL) of the capture plant. The project team will perform a techno-economic analysis to estimate the cost of capture in $/tonne net CO2 captured from the H2 plant and the levelized cost of hydrogen.

Project Benefits

Advancing the integration of carbon capture, utilization, and storage (CCUS) into steam methane reforming (SMR) processes is critical to achieving net-zero or negative carbon emissions in the production of high-purity hydrogen from natural gas. The Carbon Capture Program aims to leverage past research in materials and systems development in carbon capture technologies for application to the conditions and process requirements of SMR plants to reduce the impact on the levelized cost of hydrogen while decreasing the carbon intensity. The completion of an initial design of a commercial-scale advanced CCUS system that separates, stores, and utilizes more than 100,000 tonnes/year net carbon dioxide (CO2) with 90%+ carbon capture efficiency—from an SMR facility producing hydrogen with 99.97% purity from natural gas—will provide the basis for subsequent deployment of CCUS projects.
