Bengaluru: The Indian Institute of Science (IISc) on Tuesday stated a workforce of its researchers has developed an progressive know-how to supply hydrogen from biomass. The workforce was led by S Dasappa, professor, Centre for Sustainable Applied sciences, and chair, Interdisciplinary Centre for Power Analysis at IISc.
Stating that India makes use of almost 50-lakh-tonne of hydrogen in numerous sectors and estimating the hydrogen market to develop considerably, Dasappa stated: “However a lot of the hydrogen we presently use comes from fossil fuels by a course of known as steam methane reforming route. Now, we’ve got discovered a technique to extract inexperienced hydrogen from biomass, a renewable power supply.”
The method consists of two steps: First, biomass is transformed into syngas – a hydrogen-rich gas fuel combination – in a novel reactor utilizing oxygen and steam. Second, pure hydrogen is generated from syngas utilizing an indigenously developed low-pressure fuel separation unit.
“Each these applied sciences be sure that this course of is a extremely environment friendly methodology of producing inexperienced hydrogen. It produces 100g of hydrogen from 1kg of biomass though solely 60g of hydrogen are current in 1kg of biomass. It’s because on this course of, steam, which additionally accommodates hydrogen, participates in each homogeneous and heterogeneous reactions (in homogeneous reactions, reactants are in a single part whereas in heterogeneous reactions, the reactants are in two or extra phases),” an IISc assertion learn.
The manufacturing of inexperienced hydrogen utilizing this course of is environmentally pleasant for an additional motive, IISc stated: It’s carbon unfavourable. “The 2 carbon-based by-products are stable carbon, which serves as a carbon sink, and carbon dioxide, which can be utilized in different value-added merchandise,” IISc added.
