New Delhi may be called a green city not only because by planting more trees in every nook and corner of the city, but by replacing diesel powered automobiles and transport vehicles with CNG. This is only the beginning of a long process toward an eco-friendly, carbon neutral fuel system, finally switching over to Hydrogen as the ultimate energy carrier.

Production of H₂ via electrolysis is the royal way, but at present it is nearly four times expensive than when it is derived from fossil fuel resources. A sudden leap from fossil fuel to non conventional sources is costlier and faces consumers' resistance. In this paper, technologies for hydrogen production, storage and related features have been examined and the best energy options presented as post-Kyoto 2012 strategies for future. Renewable energy sources like bioethanol fro corn and sugar cane and bio diesel from Zetropha have also been examined in the light of vast agricultural and forest lands available in many tropical and sub-tropical countries. Photovoltaics and concentrated solar energy, wind power are also discussed, which can be harnessed from desert regions. Appropriate technological road maps have been suggested for a more cleaner, more sustainable, more affordable, and more secure energy scenarios in the Indian context.
