Early investigations seem to indicate that massive storage of carbon dioxide is possible and most of the potential lies within deep saline aquifers which are geographically widespread. Though pore space in depleted reservoirs can also be available but it is of limited capacity. Our materials research and development platform has developed a low cost, non-toxic, safe, and environmentally friendly chemistry for ensuring the long-term storage of carbon dioxide in reservoirs. Beauty of this chemistry is that it is simple and provides a one universal solution for variety of sub-surface formations. This chemistry for carbon sequestration can also be fine-tuned if needed.
