Olivine can reverse climate change and ocean acidificaiton
It is rare to come across a solution to lowering the amount of CO2 in the atmosphere that is simple, yet plausible, and which can be started right away with…
Because we don't have time to wait
Climitigation is a science-based, politically neutral think tank dedicated to mitigating climate change. There are many organizations, governments and people working on stopping or slowing the release of CO2 in the atmosphere, but there is not enough of a focus on reversing the existing damage.
We want to put a focus on the mitigating or reversing of climate change, by highlighting the technologies, ideas, companies, and people that are less discussed or on the vanguard, but that could make a significant impact on the problem.
Project Vesta is a project to sequester carbon by accelerating the weathering of a specific type of rock called olivine. When olivine interacts with water and CO2, it creates a bicarbonate and alkaline solution that eventually sequesters the carbon as rock in the sea floor and deacidifies the ocean.
While this rock is abundant and cheap, all of the unweathered sources of it are underground. The plan is to mine it, grind it, and spread it on beaches to harness the free energy of wave motion to further tumble the rocks and accelerate the weathering process. We will be creating a global network of green sand beaches to end global warming.
1 ton of olivine sequesters 1.25 tons of carbon. A volume of 7km^3 spread over the world's 2% most tidally active areas would off-set all of humanity's yearly CO2 output.
Olivine (Mg2SiO4) + 4 CO2 + 4 H2O −→ 2 Mg^2+ + 4HCO3^- + H4SiO4
CO2 is consumed, and Mg2+, Fe2+, H4SiO4 and HCO3^- are produced
Climitigation seeks to highlight the technologies and ideas that have the potential to radically shift the current equation on climate change back to neutral or in even in our favor. We seek to put a spotlight on those technologies and ideas that we think will be most impactful, so they can reach their full potential.
