Presentation Title: Hydrogen: A Green Fuel for 21st Century
Generation of hydrogen from water via electrolysis is a well-known and established technology. There are two main types of electrolyser [Alkaline and Proton Exchange Membrane (PEM)] and both are well proven and long-lived. Electrolysis has been traditionally based on an alkaline technology, but Proton Exchange Membrane (PEM) electrolysers are now coming to the forefront. However, due to the high cost of both electricity and material, only a small proportion (4 -5%) of the worldwide hydrogen production comes from electrolysis. Yet electrolyser costs are expected to drop within the few years as a consequence of standardization, mass-production, and a greater competitiveness. The demand for clean-produced hydrogen and its storage potential spell enormous possibilities for renewable electrolysis in the future. Even non-renewable electrolysis is bound to play an important role in the short-term as a source of moderate amounts of hydrogen for small fuelling stations and domestic applications. In future low-carbon economics, electrolyser technology could provide a central solution to meeting both the power management needs of the electricity sector and the needs of the transport and industrial sectors for low/zero carbon fuels. Electrolytic hydrogen could thereby displace large proportions of non-electricity fuel consumption. Hence, the new market potential for electrolyser dwarfs the existing market potential and on a global scale it is truly vast. In this talk some of the important and recent developments in the electrochemical alternatives with newer materials for hydrogen generation are discussed. The talk also covers hydrogen based technologies developed at CSIR-CECRI.
