INSUBCONTINENT EXCLUSIVE:
In the span of a decade, direct air capture technology that draws CO2 out of the atmosphere has gone from wildly expensive to somewhat
Companies like Microsoft, which set a target to eliminate its emissions by 2030, are happy to pay more to get the ball rolling
RepAir Carbon is developing a new form of carbon capture the company says could drive the cost down as low as $70 to $80 per metric ton of
$15 million extension to its Series A, the company exclusively told A Technology NewsRoom
The round was led by Extantia Capital and Taranis Carbon Ventures with participation from Ormat Technologies and Repsol
The Israeli Innovation Authority also contributed a $3 million grant.The potential cost advantage comes from the way RepAir uses electricity
Most companies rely on a solvent to remove CO2 that must be heated to release the gas so it can be transported and stored
As air or flue gas is drawn into the reaction chamber, it encounters a nickel-based electrode with a current running through it
There, hydroxide is waiting to attract carbon dioxide, converting it into carbonate and bicarbonate ions with negative electrical charges
positive electrode, they revert back to CO2 and hydroxide
Other capture devices typically need time to heat the solvent to release CO2, a process known as regeneration, and that downtime requires
more modules to capture a given amount of carbon
capture carbon from the atmosphere and from exhaust streams from power plants and the like
RepAir is currently in talks with developers to add its technology to gas turbines to help eliminate carbon emissions from data centers
