@8606bdb4 I beg your pardon. I scanned the linked story 

https://www.soest.hawaii.edu/soestwp/announce/news/4m-for-marine-carbon-removal-nopp/ 

Which mentioned using quicklime and olivine among other things- completely missed the “Electrochemical” in  the oceanacidification.noaa link, which is weird being electrochemical is kind of my day job.

OK I looked at the EbbCarbon website. If I could change my question to “what do you do with all the HCl?”

Thanks. 

 @8606bdb4 um, where are you getting the quicklime from? 

 @02870194 @30ce86c6 hey @063edef8 know about this?
