How does this compare to olivine weathering, a much cheaper technology that seems rather similar, and is already being used in many projects? Is it more effecti

  It sounds like the advantage is that can repeat the process storing CO2 underground. It sounds like a weird way to store CO2, like they are trying to do the same thing as direct capture. When storing underground was one of the big flaws with direct capture. But I would think it would be an advantage to dump the crushed olivine in the ocean where it would be sequestered for a long time. It isn't like trees where have to worry about the CO2 being released from fire or decay.
