direct air capture

CarbonCapture Inc. develops modular, scalable direct air capture (DAC) systems designed for mass production, capturing CO2 from the atmosphere and permanently storing it underground. The company sells DAC-based carbon removal credits and was named a 2023 Technology Pioneer by the World Economic Forum. Its subsidiary True North Carbon is launching the Tamarack direct air capture deployment in Canada.

Carbon Collect is a technology company developing the MechanicalTree™, a patented Passive Direct Air Capture (PDAC) system that captures CO₂ from ambient air using natural airflow rather than energy-intensive fans. The company holds exclusive global rights to ASU–Lackner patents and has deployed Gen-I (2022) and Gen-II (2025) systems, with Gen-III and Gen-IV 'Smart DAC' development underway.

Decarbontek provides a modular industrial carbon capture platform that runs on a facility's own waste heat rather than the grid. It replaces toxic liquid amines and energy-intensive steam with proprietary solid-fiber MOFs and solid adsorbents, targeting up to 90% carbon removal and lower operating costs. The company is based in Woburn, MA, and was founded by Dr. Yong Ding.
