It seems like at $94/ton CO2, we're still a long way from where this becomes viable.
At that price, to offset humanity's annual 36 Gt CO2 emissions (36 billion tons) we'd need to spend about $3.2 trillion. Per year.
Surely the cost of reducing CO2 emissions - the cost of upgrading emissions sources to alternative, lower-carbon technologies - is much less than $94/ton. And that's where we should be focusing our efforts and funding for the foreseeable future.
