Within a decade, direct air capture technology that pulls what2 It disappeared from the atmosphere from extremely expensive to a bit expensive. Companies resembling Microsoft, which set the goal to eliminate emissions by 2030, will likely be joyful to pay more for the ball. But smaller firms still do not affect prices.
The startup may have an answer that has been inspired by batteries. Coal repair It develops a recent type of capturing carbon dioxide, which based on the company can reduce the costs from USD 70 to 80 for a metric ton of carbon. This is a much cheaper price than other approaches that experts estimate that it costs about USD 600 per metric ton.
Repair recently raised an extension of $ 15 million to series A, said only TechCrunch. The round was run by Extantia Capital and Taranis Carbon Ventures with the participation of Ormat Technologies and Repsol. The Israeli Office of Innovation also brought a subsidy of $ 3 million.
The potential cost advantage results from the way the repair uses electricity to capture coal. Most firms rely on the solvent to remove what2 This ought to be heated to release gas so that it may well be transported and stored. On the other hand, repair uses electricity to drive a chemical response.
The device is “more similar to the fuel cell, but works more like a battery,” said TechCrunch co -founder and general director of Amir Shiner.
Inside, two electrodes are separated by a membrane. When air or combustion gas is drawn into the response chamber, it encounters a nickel electrode over its electricity. There, the hydroxide is waiting for carbon dioxide attraction, transforming it into carbonate and seaweed ions with negative electrical charges. Then they go through the porous electrode and separator, drawn to the positive charge of the second electrode.
When the ions hit a positive electrode, they return to what2 and hydroxide. What2 Then it is taken for storage, while the hydroxide is built until enough for the reactor to be reversed and the process repeated in the other direction.
Compared to other technologies, carbon capture repair reversibility can provide him an advantage.
Other capture devices normally need time to heat the solvent to free what2The process is often called regeneration, and downtime requires more modules to capture a given amount of coal.
“We regenerate during work,” said Shiner.
Each of the repair response chamber is filled with many stacks of the anod-sesarizer combination, and the company can use different amounts of electricity to make sure they work at peak performance.
Shiner said that technology works on the capture of carbon from the atmosphere and exhaust streams from the power plants and the like. Currently, talks with programmers have been repaired so as to add your technology to gas turbines to assist eliminate carbon dioxide emissions from data centers.
“It’s early, but we are working on it and we have a lot of interest from this particular area,” he said.
