Who We Are

Defiant Renewables Pvt. Ltd is advancing research in the area of hydrogen energy focusing efforts on developing novel hydrogen production technologies i.e. reforming technologies from renewable fuels like biogas and biodiesel. Besides, reforming technology the company is researching development of new materials for solid oxide fuel cell anodes. The integration of reforming technology and IC engines and fuel cell is an important goal of the company.

Defiant Renewables is also investing on building and operating bio gas plants together with local municipal corporations. The company is already researching on innovative technologies for  producing  non-food sugar from variable mixed solid waste for high value chemical products.  On successful completion of the project Defiant Renewables will set up plants for scaling up the projects. The company is developing low cost solutions for treating waste water, generating energy and bio fertilizer for rural applications.  Developing innovative products from wastes for various applications like water purification, soil remediation and proving suitable energy source is one of the unique ability of the company.
