Indian Researchers Develop a Method to Extract Green Hydrogen from Biomass

In News 
  • A team of researchers from the Indian Institute of Science (IISc.) has developed an innovative technology to produce hydrogen from biomass, a renewable energy source.
Details 
  • This indigenous technology is a step toward achieving the goal of Atmanirbhar Bharat, the National Hydrogen Energy Roadmap, an initiative of the Government of India that aims to promote the use of hydrogen as a fuel and reduce dependence on fossil fuels.
  • The Ministry of New and Renewable Energy and the Department of Science and Technology of the Government of India supported the project.
  • Biomass is first converted into syngas – a hydrogen-rich fuel gas mixture – in a novel reactor using oxygen and steam.
  • In the second step, pure hydrogen is generated from syngas using an indigenously developed low-pressure gas separation unit.  
  • Both these technologies ensure that this process is a highly efficient method of generating green hydrogen; it produces 100 g of hydrogen from 1 kg of biomass even though only 60 g of hydrogen are present in 1 kg of biomass.
  • This is because in this process, steam, which also contains hydrogen, participates in both homogeneous and heterogeneous reactions.
