Exclusive: DACLab says it can remove CO2 using less electricity than many competitors
Summary
Removing one metric ton of CO using direct air capture is expected to require around 2,000 kWh of energy when the technology is sorted and scaled up.One startup called DACLab says its already doing it for less, though. The round was led by early Discord investor Peter Relan with participation from Silver Lake co-founder Dave Roux, WovenEarth Ventures founder Jane Woodward, and others.In most direct air capture schemes, air is blown over a solid material capable of absorbing carbon dioxide. The heat is relatively low for a solid sorbent, around 70\xb0C, Bhandari said.The bifurcated setup is typically found at industrial sites, which have more concentrated exhaust streams. )DACLabs technology comes from TU Wien in Austria, where a partnership with Shell had produced a point-source carbon capture unit that ran for nearly three years. Hopefully we can reboot this much needed industry, because it is filled with a lot of, I would say, empty promises.Correction: Experts estimate DAC will require around 2,000 kWh of total energy (heat and electricity).
