IIT Guwahati (IIT-G) Leads the Way in Sustainable Energy Research

The School of Energy Science and Engineering and the departments of Chemical Engineering and Bioscience and Bioengineering at IIT-G are actively working to contribute to a sustainable future.

Bullet Point Summary:

  • Microalgae-based biorefinery model integrates wastewater treatment and biofuel production
  • Efficient strategy for transforming residual microalgae into energy fuel and chemicals
  • Advanced microalgal biorefinery process developed with collaboration from national and international organizations
  • Lab-scale technology for producing bio-alcohols from invasive weeds
  • Pilot scale technology demonstrated for producing liquid hydrocarbon oil as transportation fuel

The School of Energy Science and Engineering, department of Chemical Engineering, and department of Bioscience and Bioengineering at the Indian Institute of Technology Guwahati (IIT-G) are actively working to make a major contribution to building a sustainable future. Under the Microalgae Biorefinery Model, multiple research projects are underway to develop a sustainable energy model.

Prof Parameswar K Iyer, the officiating director of IIT-G, highlighted the need for research on sustainable development and said, “Alternate fuel production is the need of the hour. IIT-G is working for the last 25 years in this domain where various researchers have contributed significantly in developing a microalgae-based biorefinery model under which waste treatment, as well as fuel production, can be carried out simultaneously. Efforts to utilize the rich biomass of NE reason for bioethanol/methanol/butanol production as an alternative to fossil fuels.”

Prof Vaibhav V Goud, head of the School of Energy Science and Engineering at IIT-G, and his research team have formulated an efficient strategy for transforming residual microalgae/biomass into energy fuel and chemicals. By implementing specific alteration strategies, such as inhibiting steps, researchers have diverted the process cycle to recover the product of choice (H2, biogas, and chemicals). Their findings showed that the combined use of residual microalgae with biomass (rice straw) enhanced energy recovery and provided a sustainable approach for developing a biomass/microalgae-based biorefinery.

Prof Kaustubha Mohanty, Adjunct Faculty at the School of Energy Science and Engineering, and his research team have developed an advanced microalgal biorefinery model that integrates wastewater treatment and high-value biofuel production via hydrothermal liquefaction (HTL) where domestic sewage sludge and microalgal biomass are used as co-feedstock. The process resulted in 40% biocrude yield and properties comparable to petroleum crude. The developed biorefinery process suggests that one million domestic sewage wastewater will deliver 2,500 kg biomass feedstock and result in 980 Kg biocrude followed by 5,000 kg CO2 sequestration.
