CO2 Capture

Carbon Capture

Large-scale Carbon Capture System First of Its Kind

Air Products operates a large-scale system to capture carbon dioxide (CO₂) from our two steam methane reformers located within the Valero Refinery in Port Arthur, Texas. The recovered and purified CO₂ is delivered by pipeline for use in enhanced oil recovery operations.

Described by the Department of Energy as a milestone in its Industrial Carbon Capture and Storage program, this unprecedented achievement, which uses an Air Products innovative technology, was the first-of-its-kind operating at such a large scale.

World’s Largest Carbon Capture for Sequestration Facility

Air Products will invest $4.5B to build-own-operate the world’s largest blue hydrogen production facility, producing over 750 MMSCFD of blue hydrogen in Louisiana, USA. A portion of the blue hydrogen will be compressed and supplied to customers by our U.S. Gulf Coast pipeline network; the balance will be used to make blue ammonia that will be transported around the world and converted back to blue hydrogen for transportation and other markets.

The megaproject will also capture over five million metric tons per year of CO₂, making it the largest carbon capture for sequestration facility in the world. Louisiana’s geology is seen as some of the best in the world for permanent geologic sequestration.

The project is expected to be operational in 2026. 

Sequestration Facts

Permanent Sequestration

Carbon sequestration is permanent and is an environmentally sound disposition of CO₂ that does not fracture rock.

Stable Pore Space

More than 400 million metric tons of CO₂ have already been injected in stable pore space over 50 years worldwide.


During sequestration, continuous measurement, monitoring, verification, and reporting are conducted.

Canada Net-zero Hydrogen Energy Complex to Capture >95 Percent CO₂ 

Air Products and its subsidiary Air Products Canada Ltd., in conjunction with the Government of Canada and the Province of Alberta, is building a landmark new net-zero hydrogen energy complex.

The project will begin with a transformative $1.6 billion (CAD) net-zero hydrogen production and liquefaction facility expected onstream in 2024. Air Products will deploy advanced hydrogen technology and innovative design to deliver net-zero emissions. The new facility will capture over 95 percent of the carbon dioxide (CO₂) from the feedstock natural gas and store it safely back underground. Hydrogen-fueled electricity will offset the remaining five percent of emissions.

The clean energy complex will help refining and petrochemical customers served by the Air Products Heartland Hydrogen Pipeline to reduce their carbon intensity. The complex also marks a first in the wider use of hydrogen in Alberta, enabling the production of liquid hydrogen to be an emissions-free fuel in the transportation sector, and to generate clean electricity. This is expected to have a positive impact in lowering Alberta’s carbon emissions.

Paving the Way to Net Zero in Canada

Multi-billion dollar landmark new net-zero hydrogen energy complex will make Edmonton, Alberta the center of western Canada’s hydrogen economy and set the stage for Air Products to operate the most competitive and lowest-carbon-intensity hydrogen network in the world. .
