Characterization studies on surface activation of phosphor bronze wire mesh via different chemical means for water distillation applicationsBy Rupsha Bhattacharyya, Dibyendu Bandyopadhyay, Hemant R Patel, Ravindranath Rakate, Seemita Banerjee, Asheesh Kumar
Abstract: Surface activation of phosphor bronze structured packing modules is an important step in the manufacturing of high efficiency water distillation columns as it ensures excellent mass transfer behaviour and overall process intensification. These packed columns are used in the nuclear industry for heavy water production and purification. Activation is generally achieved through a treatment involving aqueous NaOH solution with bubbling of oxygen gas through it. This leads to the development …

Diversification of the Indian Nuclear Industry via Nuclear Cogeneration: Some InsightsBy Rupsha Bhattacharyya
Abstract: The Indian nuclear industry provides 2% of the electricity generated in India today. Other than its growing importance as a source of clean base load electricity in the clean energy transition as a complement to growing shares of variable renewables in India’s energy mix, it can continue to remain relevant and play a vital role in India in the years to come by suitably re-inventing itself to provide a variety …

Design Calculations and Parametric Analysis of a Membrane Permeator for Hydrogen-Helium SeparationBy Rupsha Bhattacharyya
Abstract: Palladium or palladium alloy-based membrane permeators have been proposed to be used for the separation of hydrogen isotopes from helium in fusion energy plants on account of the very high selectivity for hydrogen exhibited by these membranes. In this work, the preliminary design and parametric analysis of a single stage membrane permeator having different flow patterns have been carried out and the effect of various parameters on the membrane area …

Assessment of a Wind Energy Conversion System for Sustainable Hydrogen Production by Alkaline Water Electrolysis in India: Effect of Geographical Location and Wind Turbine TypeBy Rupsha Bhattacharyya
Abstract: The use of wind energy for electricity generation and use of this electricity for hydrogen production by alkaline water electrolysis promises to be a truly sustainable scheme for the postulated hydrogen economy. This work addresses the feasibility assessment of a standalone wind energy based turbine generator system that meets the energy requirements of the electrolysis process at several locations in India. Energy requirement for electrolysis depends on the hydrogen production …

Hydrogen from Alkaline Water Electrolysis: A Case Study on Process Economics of Decentralized Production in the Present Indian ScenarioBy Rupsha Bhattacharyya, Sandeep K.C., Sachin Kamath, Krunal Mistry
Abstract: Distributed or decentralized hydrogen production by alkaline water electrolysis and use of renewable energy resources to obtain at least a part of the electricity necessary for it can be a truly sustainable scheme that will enable several categories of hydrogen users to reduce their carbon footprint significantly in the near future. The process economics of producing hydrogen through electrolysis, with focus on the production cost per unit of hydrogen in …
