Toward the Realization of One of the World’s Largest DAC Plants

In April 2025, a cutting-edge MATHESON air separation unit (ASU) facility called Penwell began operations in Penwell, Texas. The Penwell ASU is designed to provide vital oxygen and clean dry air (CDA) to a world-first direct air capture (DAC) facility developed by 1PointFive. This DAC facility will capture and remove CO2 directly from the atmosphere and safely store it underground nearby, contributing to the achievement of the international target of keeping the global rise in temperature to within 1.5℃. The ASU’s oxygen supply is critical to efficient chemical reactions in the DAC system, enabling the pull of CO2 from the air and storing it forever. The DAC facility and the ASU will be powered by 100% renewable energy from a large, nearby solar panel field. When this technology is proven successful, 1PointFive and others will aim to build DAC hubs consisting of multiple units around the world, allowing MATHESON to grow and create opportunities for us to construct more ASUs.
