Description
TDA Research of Golden, Colorado, with GE Research, reports final results under award DE-FE0032261 for a direct air capture system. Gokhan O. Alptekin led the project, with Ambalavanan Jayaraman and Bill Gerstler. The work ran from September 2023 to August 2025. Its aim was to pull carbon dioxide straight from open air at lower cost, using structured parts coated with a heat-stable sorbent that grabs the gas.
The team paired that sorbent with store-bought tube-in-plate heat exchangers. An early cost study put capture at 255 dollars per metric ton, not counting transport and storage, before design tuning. An early life cycle count found 0.057 kilograms of carbon dioxide released for each kilogram captured. The team also made 4 liters of finished sorbent in batch runs and passed early project milestones.
