Hydrogen economy – opportunities and prospects

Prospects on Fuel Economy Improvements for Hydrogen Powered Vehicles

Fuel cell vehicles are the subject of extensive research and development because of their potential for high efficiency and low emissions. Because fuel cell vehicles remain expensive and the demand for hydrogen is therefore limited, very few fueling stations are being built. To try to accelerate the development of a hydrogen economy, some original equipment manufacturers (OEM) in the automotive...

Electrocatalysis for the Hydrogen Economy

This chapter deals with the concept of “hydrogen economy”, which was introduced by John O.M’ Bockris in 1972. We summarize the fundamental principles and the progress for the reactions relevant to the hydrogen economy, namely the hydrogen and oxygen evolution for water electrolyzers, and the hydrogen oxidation and oxygen reduction for fuel cells. The activity of each reaction can be correlated ...

Hydrogen Masers. I: Theory and Prospects

The discovery of the first naturally occurring high gain hydrogen recombination line (HRL) maser, in the millimeter and submillimeter spectrum of the emission line star MWC349, requires an expansion of current paradigms about HRLs. In this paper we re-examine in general the physics of non-LTE populations in recombining hydrogen and specify the conditions necessary for high-gain masing and lasin...

Integrating India With the World Economy: Progress, Problems and Prospects

India was largely insulated from the world trading system for more than four decades after independence in 1947. Pursuit of an inward-oriented development strategy, rationalized both by a wary, almost hostile, attitude towards foreign trade, technology and investment, and by pessimism about export markets, inevitably led to India becoming marginalized in world trade. During the period of rapid ...
