An Israeli startup has joined the fight against global warming by looking for a solution in the most distant regions of the Earth’s atmosphere, where the company hopes to send a bunch of balloons that will trap carbon dioxide and bring them back to Earth for recycling.
High Hopes Labs has developed a system that captures carbon in the atmospheric region where it almost solidifies, high above the Earth. “The beautiful thing is, capturing the gas is very easy when it’s close to freezing,” company CEO Nadav Mansdorf told Reuters.
Emissions of carbon dioxide, burning fossil fuels and industrial agriculture are the main causes of climate change. But removing CO2 from the atmosphere at standard temperatures requires a lot of energy and money and has been an underutilized solution by governments and businesses.
“Carbon freezes at a temperature of minus 80 degrees (Celsius), and the only place where we can find carbon at a temperature close to that is 15 kilometers above our heads”, says the executive.
The company has tested its system on a small scale, says Mansdorf, by launching balloons filled with gas with a box that serves as a carbon-capture device beneath those balloons.
Frozen carbon is separated from the air to be brought back to earth and can be recycled.
The company plans to build larger balloons within two years, each capable of removing a ton of carbon a day at a cost of less than $100, far short of the amount invested in onshore facilities that have the same mission, Mansdorf said.
