Deep-Tech Decarbonization: IIT Bombay Establishes Subsurface CO₂ Storage and Mineralization Testbed
In a pioneering technological milestone aligning with the nation's clean energy goals, India’s first Integrated Carbon Capture, Utilisation and Storage (CCUS) Field Laboratory Facility has been officially inaugurated at the Indian Institute of Technology (IIT) Bombay. Launched under the high-profile **Bharat Innovates 2026** framework, the installation marks a major transition from theoretical laboratory tracking to pilot-scale engineering implementation, validating indigenous methods designed to permanently neutralize carbon footprint indexes.
The Technical Architecture and Basalt Drilling Initiative
The newly operational facility bypasses standard single-tier air scrubbers to test a complete, multi-tiered circular emission loop under rigorous field constraints:
- The Mineralization Loop: The system utilizes industrial wastewater and non-potable water matrices to capture flue-gas carbon dioxide emissions. Instead of requiring energy-heavy chemical thermal stripping, it directly converts gaseous emissions into stable, value-added industrial-grade **carbonate and bicarbonate salts**, suitable for immediate manufacturing reuse.
- The Deccan Traps Drilling Initiative: Crucially, the complex houses India’s first pilot-scale **scientific drilling initiative**. This enables geologists to inject compressed carbon dioxide deep into the massive **Deccan Traps basalt rock formations**, tracking chemical interactions to evaluate the long-term potential of permanent mineral storage in trap basalt.
- Strategic Policy Linkages: By optimizing deep-well storage security indices, the project functions as a primary technical pillar supporting India’s **Panchamrit climate commitments** and long-term Net-Zero emission timelines.
For TNPSC and Civil Services Science & Tech aspirants, this technical installation is highly relevant under modules covering 'Applied Chemistry, Climate Change Mitigation Strategies, Industrial Decarbonization Models, and Green Technology Initiatives'.
