Matheson Tri-Gas wins oxygen contract for Texas DAC project
Matheson Tri-Gas, the US operating subsidiary of Japan’s Nippon Sanso Holdings, said July 20 it had won a gas supply agreement with Occidental’s 1PointFive to provide oxygen to 1PointFive’s direct air capture (DAC) facility under construction in Texas.
Matheson will establish an air separation unit to supply the oxygen to the facility, which has been named Stratos by 1PointFive. The oxygen is used in the DAC process to produce a pure stream of CO2 for later sequestration.
Stratos is expected to begin operations in mid-2025, capturing up to 500,000 tonnes/year of CO2 using technology developed by Canada’s Carbon Engineering that captures CO2 from the air using a potassium hydroxide solution.
