Putting Rocks to the Test for Reliable Carbon Storage

Putting Rocks to the Test for Reliable Carbon Storage
What's a key element of reliable carbon storage? Understanding the Earth's rock. Learn from Science Rob how we test rock mechanical properties in the lab.

In carbon capture and storage (CCS) projects, as CO2 is injected into the reservoir, pressure naturally increases over time. Ensuring that this pressure remains within safe limits is paramount to prevent the caprock from fracturing, which could compromise containment. So how do rocks perform under pressure?

In Science Rob's latest experiment, kitchen science meets geomechanics: Learn from Rob about fundamental geomechanical concepts like Young's modulus and Poisson's ratio, as he tests how different foods (representative of a rock formation) respond to stress. This and other subsurface insights plays a crucial role in evaluating carbon storage sites for appraisal. Learn more about carbon storage evaluation measurements and how they are an early, critical step in any carbon sequestration project.
