The Mission

We envision a future where we are not only treating wastewater but also producing renewable energy at the same time, offsetting the energy costs of industrial anaerobic wastewater treatment processes.

The Challenge 

Climate change and global energy crisis requires the use of sustainable methods of energy generation rather than from fossil fuels. So, it is vital to develop efficient energy harvesting techniques. The major driving force is the huge release of waste energy (like exhaust gasses) by industries. What if it was possible to generate energy out of the flow of gasses? That is precisely the concept of a theoretical bubble column power generator (BCPG).

The Solution

The BCPG is a novel concept that uses multiphase flow phenomena and Faraday’s law to generate electricity. Magnetic nanofluids are used, containing dispersed magnetic nanoparticles (MNPs). When placed under an external magnetic field, the MNPs align themselves to this field. Therefore, when a stream of bubbles is made to pass through, it disturbs the MNP alignment and according to Faraday’s law, emf is induced. So, this can be converted into a technology to gain energy out of unavoidable movement of gasses. There has not been much research into this domain or successful implementation due to its complexity, making it unique.
