Carbfix wants to turn carbon into rock

Source: Bloomberg

Icelandic startup Carbfix is building the Coda Terminal, a hub which will receive carbon dioxide transported to Iceland in specially designed ships. The hub will turn the CO2 in underground rock using a technique that imitates and accelerates the natural process of mineralizing carbon, providing a permanent storage solution. The CO2 is turned into stone in less than two years, after this no monitoring is needed. The service will be accessible for businesses in Northern Europe starting in 2025. The storage will be cheap, costing less than €20 per metric ton.

These balloons can capture CO2 from the air

Capturing CO2 with balloons? On April 16 the startup High Hopes launched their first balloon in the air and watched as it ascended. It was carrying new technology designed to capture CO2 from the atmosphere at a height of 16km. High Hopes’ product is less expensive to run compared to existing direct-air-capture tech. Instead of pulling in the air near the ground, they use machines at high altitudes, where temperatures can dip to minus 70 degrees Celsius. At minus 80 degrees Celsius, carbon dioxide freezes and with relatively little energy, the air can be cooled enough to freeze the carbon out of the air and capture it. Each balloon will float upwards for 8 to 10 hours to capture the CO2. The first facility will start with 100 balloons, capturing around 30,000 metric tons of CO2 each year.
