Recent directions of world hydrogen production

Hydrogen can be produced on a large scale through economically favorable raw materials and processes. Utilization of water as an exhaustible supply of hydrogen is well known. This is very much an area open to research, so that traditional methods can be considered, as well as non-traditional approaches. This paper examines the present status and looks at different approaches for technological advances. The paper reports on some of the new developments in the progress of the recent directions of world hydrogen production, with emphasis on photolytical hydrogen processes. The aim of this article is to inform the reader of new research on hydrogen production. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
