MATHESON Signs Oxygen Supply Contract for 1PointFive's DAC Plant

~DAC potential for carbon neutrality~

IRVING, Texas--(BUSINESS WIRE)--Nippon Sanso Holdings Corporation (“NSHD”, President CEO: Toshihiko Hamada) hereby announces that Matheson Tri-Gas, Inc. ("MATHESON", headquartered in Texas, U.S.), NSHD’s U.S. operating company entered into a gas supply agreement with 1PointFive to provide oxygen for the carbon capture, utilization and sequestration company’s first Direct Air Capture (DAC^*) plant in Texas.

MATHESON will invest in and establish an Air Separation Unit to supply Oxygen to “Stratos”, 1PointFive’s DAC plant under construction in Ector County, Texas. The Oxygen is used in the DAC process to produce a pure stream of CO₂ which is then securely sequestered in geologic reservoirs.

Stratos is expected to commence operations in mid-2025 and capture up to 500,000 tons of CO₂ per year when fully operational, making it the world’s largest DAC plant. The Oxygen solution was developed by MATHESON’s onsite business unit in collaboration with our leading technology and engineering partners. The solution targets flexibility and reliable plant operations.

This initiative demonstrates MATHESON’s commitment to significant growth through gases supply for highly strategic, commercially sound projects and represents an additional dimension for its onsite footprint. This will strengthen its presence in the growth segment within the Southern United States.

NSHD Group, in its effort to foster a carbon neutral society, is pursuing multiple business and program initiatives to select customers for carefully selected projects. We are committed to continue to explore opportunities to realize growth and a carbon-neutral society by expanding this business on a global scale.
