So, when we talk about energy, we're considering every aspect of this intricate process.

The Climeworks Technology: How it Works

Climeworks utilizes a fascinating process to capture CO2. Basically, large fans draw in ambient air, which then passes through a filter coated with a special chemical absorbent. This absorbent selectively grabs onto the CO2 molecules. Once the filter is saturated, the plant uses heat and energy to release the captured CO2. This concentrated CO2 is then mixed with water and injected deep underground, where it reacts with the basaltic rock, eventually turning into stone. This entire process, from capturing the air to storing the CO2, requires energy. The core technology involves the use of specialized filter materials that efficiently capture CO2. These filters are designed to maximize the capture efficiency while minimizing the energy required. Heat is then used to release the CO2 from the filters. This heat source can come from various sources, including renewable energy, to reduce the overall carbon footprint of the process. The captured CO2 undergoes a series of steps to prepare it for storage. This might involve compression and transportation to the storage site. The final step is the underground storage, where the CO2 reacts with the basaltic rock through mineralization. This turns the CO2 into stable minerals, permanently removing it from the atmosphere. Understanding each step in this process helps us appreciate where energy is used and how Climeworks is working to optimize its energy consumption.
