Carbon capture storage safety: How our engineers make it happen
When Dr. Ganesh Dasari was a doctoral candidate at Cambridge University, he didn’t know that his passion for civil engineering would steer him toward becoming a leading expert in carbon storage technologies.
Today, he is part of a team of geoscientists and engineers at ExxonMobil who are finding new ways to safely store carbon underground. The technologies they’re developing today could shape the future of large-scale carbon storage projects around the world.
Dr. Dasari and the team are busy finding safe and secure geologic locations to store CO2 in US, Europe, and Asia. The projects include CCS hubs in Houston, Louisiana Pecan Island, Malaysia and Indonesia. The team is developing a safe process to inject CO2 thousands of feet under the earth’s surface into carefully selected geological formations where it can be permanently stored. Once underground, the CO2 is initially held in place by a thick seal rock and it gradually transforms into solid minerals.
ExxonMobil and other companies believe a large-scale development of CCS in Houston could store up to 50 million metric tons per year of CO2 by 2030 and double that amount by 2040.
Energy Factor spoke with Dr. Dasari to better understand how CO2 storage sites are carefully and rigorously selected. As a leader in locating potential CO2 storage sites for our carbon capture and storage projects, Dr. Dasari is an authority on safety considerations in carbon storage planning.
