"The world's countries may have pledged to cut its carbon pollution, but with global emissions reaching an all-time high last year they've fallen far short. Digging out of that hole is going to require removing carbon straight from the atmosphere. But it comes with a hefty price tag, mostly because of the energy required. Removing one metric ton of CO 2 using direct air capture is expected to require around 2,000 kWh of electricity when the technology is sorted and scaled up."
"One startup called DACLab says it's already doing it for less, though. "We have data that I can share with you at 1,500 kilowatt hours per [metric] ton," said Aditya Bhandari, co-founder and CEO of DACLab, told TechCrunch. DACLab, which has been operating stealthily for the last four years, emerged today with $3 million in seed funding, the company exclusively told TechCrunch."
Global emissions reached record highs, creating a need for direct removal of CO2 from the atmosphere. Direct air capture typically requires roughly 2,000 kWh of electricity per metric ton when scaled. DACLab reports data indicating capture at about 1,500 kWh per metric ton and has secured $3 million in seed funding. Traditional DAC often combines capture and release in one unit and uses high-temperature heat (80°C–120°C) to regenerate sorbents. DACLab separates capture and release, repurposing industrial split designs, and reports a relatively low regeneration temperature for a solid sorbent around 70°C.
