RE: [geo] McDermott White Paper (2002) on accelerated carbonate weathering as a CCS approach

My chemistry is as or more rusty, but isn’t HCO3- in a second equilibrium, with CO2 and water? Does increasing the HCO3- concentration push CO2 out of the ocean? Peter Flynn Peter Flynn, P. Eng., Ph. D. Emeritus Professor and Poole Chair in Management for Engineers Department of Mechanical

Andrew cc list: 1. Thanks again for spotting an interesting paper. I will take a slight exception to a summary using the single sentence from the abstract that you gave (below). This is NOT a paper about geoengineering. Not even SRM. It is only about the sulfur compound approach. It has

Re: [geo] McDermott White Paper (2002) on accelerated carbonate weathering as a CCS approach

In response to numbered topics: 1) We think that a significant # of coast power plant CO2 could be mitigated for <$30/tonne CO2. Why hasn't this been pursued? - ask DOE who have declined every proposal we've offered. 2) Actually it could be used for CDR: biomass + O2 + heat --> energy + CO2 --->
