About
DACLab is a Palo Alto-based climate-tech startup developing a modular solid-sorbent direct air capture system branded “Kelvin,” using a patent-pending Temperature Vacuum Swing Adsorption (TVSA) cycle that regenerates at ~70Β°C and below 1,800 kWh/ton. The company emerged from stealth in September 2025 with a $3M seed round led by Peter Relan, and has run over 2,000 hours of pilot testing across two 100-ton/year pilots. Klaus Lackner serves as a technical advisor.
