Geological CO2 Storage Optimization

Detailed overview of innovation with sample startups and prominent university research


What it is

Geological CO2 storage optimization refers to the development and implementation of technologies and strategies that enhance the efficiency, safety, and capacity of storing captured CO2 in geological formations. This involves identifying and characterizing suitable storage sites, optimizing injection processes, monitoring storage integrity, and minimizing environmental risks.
