Cost-Efficient DAC Systems

A new enterprise named DACLab has publicly introduced its inaugural commercial product — a modular DAC system (also known as a Direct Air Capture system). The company has secured $3 million in initial funding from a group of private investors with backgrounds in technology and climate-focused ventures. Simply dubbed Kelvin, the core innovation of this DAC system is a patented process that utilizes a low-temperature vacuum swing adsorption (TVSA) cycle, which the company states reduces energy consumption by approximately half compared to existing DAC technologies. This design operates at temperatures as low as 70 degrees Celsius, which enables it to leverage low-grade waste heat from industrial sources. DACLab's system is engineered to be mass-manufacturable and modular. It is intended for deployment in projects involving synthetic fuel production or geological carbon sequestration. DACLab asserts its current cost is $500 per ton of captured CO₂ at a small scale, with a projected path to reduce that figure to $250 per ton at larger operational volumes, independent of government subsidies.
