High Hopes plans to extract atmospheric CO2 with hot air balloons

German and Israeli start-ups choose Earth Day to announce bold launch plans Carbon capture Plan with balloons. Big hope We believe that the proposed solution will make it easier and cheaper to extract large amounts of CO2 from the air. So far, the company has only launched a few trial missions to test the theory, but it is well encouraged to publish its ideas.

Carbon dioxide freezes at minus 78 degrees Celsius (-109 degrees Fahrenheit) to make dry ice. This requires a lot of energy. High Hopes founder Eran Oren says that if you let nature do most of the work, you can create smarter, less energy-consuming ways.

At certain altitudes, temperatures plummet, like the tropopause, the boundary between the tropopause and the stratosphere.The· The average temperature there is said to drop to an average of -60 degrees Fahrenheit (-76 degrees Fahrenheit).

In Oren’s view, a few more degrees of cooling of CO2 will make it solid. The solid CO2 is then supplied to the pressure vessel (returns to gas when warmed) and returned to the ground.

These pressure vessels can be stored or passed to companies that use CO2 in processes such as agriculture and agriculture. Chemical producer.. Hell, you can even sell it to a dry ice company, but it has no effect on the project’s climate impact.

So far, the company has developed a smaller version of the aerial compressor and sent it into the air. We used balloons in these first experiments, but we hope that eventually a custom High Hopes balloon will appear in the air.

Oren aims for a system that can emit 1 metric ton of CO2 per balloon per day at a cost that enables the sale of carbon credits. Given that the Earth currently emits more than 117 million tonnes of CO2 daily, the High Hopes will need a lot of balloons like hell.
