100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Under pacts signed on July 29 by India’s junior science minister Prithviraj Chavan and UK minister for science and universities David Willets in New Delhi, the two countries will invest £ 3 million (US$ 4.7 million or Indian rupees 218.06 million) each to promote partnerships between groups already working on fuel cells. The proposed initiative will address systems research programmes in fuel cell technologies including energy support through joint India-UK academic programmes. Sh. T. Ramasami, Secretary, Department of Science & Technology informed that Indo-UK joint workshop on fuel cell technology would be organized during September 15-17, 2010 at Centre for Fuel Cell Technology Chennai.
