When I ran the costs of the entire cycle, I obtained a total cost
which is about twice that for the creaton of and deep burial of
biochar. That is about the same as for olivine mineralization of the
carbon dioxide. The advantages of using olivine are two-fold: (i)
absolutely permanent removal of the carbon from the carbon cycle; (ii)
potentially costs dropping to around a third of the starting figure.
