    This implies 3 main problems:

    1. They’re using the captured carbon for extracting more oil, which is self-defeating. That’s not surprising considering who’s been behind this kind of technology.
    2. It means allocating geothermal energy to something else. Is there a dislocation of energy supply here? Are other energy users in Iceland using fossil fuels because they can’t access geothermal due to the Climeworks?
    3. Places with geothermal are rare, thus it’s an exceptional example, not one that can be repeated easily. Having that device be powered by fossil fuels would be, again, self-defeating.
