- IIT Jodhpur’s innovative technology uses algae-assisted fuel cells to capture carbon dioxide, treat wastewater and generate power.
- Compared to the conventional method of bubbling flue gases into algal ponds, their indirect biochemical route proves more efficient.
- It converts CO2 into carbonates, enhancing the solubility of inorganic carbon in water, thereby fostering increased carbon retention in the water.
- The use of closed systems like PBRs is highlighted as preferable to open ponds.
- They prevent decomposition of bicarbonates into CO2 and maintain pH levels.
- Additionally, the technology utilizes wastewater, utilizing a thermo-tolerant algal strain (Chlorella vulgaris) capable of thriving in such conditions.
