Why Don’t We Do That Yet? (Use Olivine for CO2 Reduction)

Here’s an interview with Prof. Olaf Schuiling, one of the main proponents of using olivine:

I found this on the “SmartStones” Foundation website, which is a new foundation set up recently to spread the word about this way to solve global warming.

It’s in Dutch language, which means I can understand about 70 percent. I did understand that he said to the journalist who did the interview: “The first question is always ‘Why don’t we do that yet?'”

So that was her first question.

It’s a good question. His answer was that maybe this proposal is not “sexy” enough. It is very simple. Nature has disposed of CO2 by exactly this process since the beginning of time. There is no exciting new technology involved. You just find yourself some greensand and put it on a beach, or on a field.

My answer would be: We don’t do it yet because there is no legal obligation for people emitting CO2 to capture and dispose safely of an equivalent amount. If there was, this process would probably one of the cheapest options around.

And it follows from my answer that it would be desirable to have such a legal obligation, maybe phased in over a couple of decades. Start out with requiring offsetting only 10 percent of emissions, and gradually increase that percentage over the years.

  1. Numbers! Where are the numbers.
    How many acres, how much money, and how many pounds of ‘minerals’ would
    be required to ameliorate CO2 growth?

  2. Forgot to check “Notify of followups” and “Notify of new posts”

    CO2 amelioration requires explanation of cost,
    would y’all say?

  3. Usually i’m against the idea of Geoengineering, and I hope this doesnt sound ignorant, but I don’t understand why we (as a species) don’t use the earth’s vast ocean “desserts” to either increase albedo by spreading thousands of square miles of thin floating white mats over the water or use mats covered with those tiny plants that make the stones near the beach slippery to soak up CO2
