The CDR potential and possible environmental
side effects are estimated for
various COA deployment scenarios, assuming olivine as the alkalinity source in ice ‐ free coastal waters (about 8.6 % of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH. Our results indicate that for a large ‐ enough olivine deployment of small ‐ enough grain sizes (10 µm), atmospheric CO2 could be
reduced by more than 800 GtC by the year 2100.
The main reason for these new low viscosity oils is fuel efficiency, the
side effect is engineers have changed the oiling systems on new cars in
various ways that do not tolerate high viscosity oils, but could assume you are correct about
reducing warm up time before oil flows to all internal parts in the engine.
