And the sea urchins helped.
“Experts at Newcastle University, UK, have discovered that in the presence of a Nickel catalyst, CO2 can be converted rapidly and cheaply into the harmless, solid mineral, calcium or magnesium carbonate. This discovery, which is published today in the academic journal Catalysis Science & Technology, has the potential to revolutionise the way we capture and store carbon enabling us to significantly reduce CO2 emissions – the key greenhouse gas responsible for climate change.” [EurekAlert]
A chemistry lesson for the ‘Experts at Newcastle University’: Water absorbs CO2. If the pH is above 6.4 then bicarbonate is formed faster than you can *think* ‘catalyst*. If calcium or magnesium are present, then the carbonate will form immediately. No catalyst required.
Catalytic hard water scale deposition. One assumes they had the cations in solution. No mention where they are going to get the Ca and Mg for chalkifying all man made CO2.
Pray explain where the calcium or magnesium required for this process comes from?
