Sequestering CO2

Sequestering carbon dioxide, aka carbon capture and sequestration (CCS) is an important topic in today’s world of  climate change mitigation.

Here’s an article, submitted by 2GreenEnergy supporter Cameron Atwood, that promotes the concept of pumping CO2 into rock formations and allowing the gas to be transformed into solids (carbonates) that are more likely to “stay put” than simply pumping the gas itself underground and hoping it doesn’t leak to the surface.

Incidentally, this is a phenomenon that occurs naturally in our ocean biomes, where high concentrations of CO2 enable shellfish to flourish.  Upon the death of these animals, their carbon-rich shells sink to the bottom, where they are sequestered for hundreds of millions of years, as they are subducted under tectonic plates.  Talk about “staying put.”
