Help us inspire more people to remove carbon dioxide from the air

  • Hi, Climeworks is being hunted! Help us inspire more people to remove carbon dioxide from the air and check us out on
    ProductHunt where we launched today:
    We want to inspire 1bln people to become climate positive. Product Hunt can help us gain feedback and visibility. Happy to hear your thoughts and feedback!

  • Wow, I didn't know about that! Cool!

  • @ldeddens upvoted! Congrats on the launch.

    Perhaps you can tell the community here a bit more about what Climeworks does and how they do it?

  • @Eric-Vanular Thanks Eric!

    Our CO₂ collectors capture carbon dioxide in a two-step process. First, air is drawn into the collector with a fan. Carbon dioxide is captured on the surface of a highly selective filter material that sits inside the collectors.
    Second, after the filter material is full with carbon dioxide, the collector is closed. We increase the temperature to between 80 and 100 °C - this releases the carbon dioxide.

    Finally, we can collect this high-purity, high-concentration carbon dioxide. The air-captured carbon dioxide can either be recycled and used as a raw material, or completely removed from the air by safely storing it.

    We mainly store it with the Icelandic company Carbfix. Carbfix mixes the carbon dioxide with water and pumps it deep underground. Through natural mineralization, the carbon dioxide reacts with the basalt rock and turns into stone within a few years.

    The carbon dioxide is thus removed from the air and returned to earth, permanently and safely. With our machine-based solution, we can exactly measure how much carbon dioxide has been removed and turned into stone.

    Hope that helps?!

  • @ldeddens Awesome technology and well done on the launch! It looks like your approach is to offer a monthly subscription with a certain amount of CO₂ mitigated.

    Is there a limit to how much carbon dioxide can be safely pumped into the ground?

  • @Hannah-Smith Thanks for asking! Carbon mineralization in basaltic rocks offers a global storage potential that exceeds anthropogenic emissions. This article in science direct states the Icelandic Rift System has a capacity of 50 million tons of carbon dioxide per year and an overall global capacity of 30 trillion tons of carbon dioxide. Hope that helps?
