This implies 3 main problems:
- 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.
- 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?
- 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.
