Hydrogen Storage Will Solid State Hydrogen Storage Bring the Breakthrough for the Energy of the Future?
Hydrogen - a colourless, odourless gas is increasingly gaining attention as a future source of energy free from environmental pollution. Its new use has been found in the automobile and power generation sector. But the storage of hydrogen has always been a problem due to its small molecular size – now solid state hydrogen storage technology could bring a breakthrough...
The biggest advantage with hydrogen is that it has the highest energy content per unit mass among known fuels and it burns to produce water as a by-product. It is, therefore, not only an efficient energy carrier but also an environmentally benign fuel as well. In fact, India's Ministry of New and Renewable Energy (MNRE) have been supporting a broad based research, development and demonstration (RD&D) programme on different aspects of hydrogen energy for over two decades.
National Hydrogen Energy Road Map for India
Consequently, a National Hydrogen Energy Road Map was prepared in 2005 which provides for various pathways for development of hydrogen energy i.e., production, storage, transport, safety, delivery and applications. However, the current technologies for use of hydrogen are yet to be optimised and commercialised but efforts for the same have already started.
96 Percent of Hydrogen Production From Hydrocarbons
Hydrogen is found only in combined state on earth, and therefore its production involves the process of its isolation from its compounds, a process that itself requires energy. Globally, about 96 percent of hydrogen
is produced presently using hydrocarbons.
About four per cent hydrogen is produced through electrolysis of water. Refineries and fertilizer plants are major in-situ producers and consumers of hydrogen in India. It is also produced as a by-product in chloro-alkali industry.
