Mobility (transport of people and goods) is a socio-economic reality and need for which is bound to grow in the coming years. Modes of transport should be safe, economic and reasonably environmental friendly. Hydrogen could be ideal as a syn the tic energy carrier for transport sector as its gravietric energy density is very high,a bundantly available in combined form on the earth and its oxidation product (water)does not contribute to green house gas emissions. However, its sustainable production from renewable resourcese conomically, on-board storage to provide desirable driving range, usage in durable energy conversion device sand development of in frastructure for its delivery remain significant challenges. In this article, recent developments in the field of production, storage, transport and delivery of hydrogen along with environmental and safety aspects of its use as an energy carrier are presented. Almost anyenergy source can be used toproduce hydrogen. Presently, non-renewable sources dominate hydrogen production processes but the need of the hour is to develop and promote the share of renew ablesources for hydrogen production to make it completely sustainable. Hydrogen may be used as fuel for almostany application, where fossil fuels are used presently and would offer immediate benefits over the convention al fuels, if produced from renewable sources. For a chieving a successful" hydrogen economy" in the near future, the technical and economic challenges as sociated with hydrogen must be addressed quickly. Finding feasible solution stodifferent challenges may take some time but techno- logical break through by wayofon-going efforts do promise hydrogen as the ultimate solution for meeting our futureen ergyneeds for the transport sector.
