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

The proceedings from the Department of Energy (DOE) Hydrogen and Fuel Cells Program and Vehicle Technologies Program Annual Merit Review and Peer Evaluation Meeting on May 14–18 in Arlington, Virginia showed encouraging progress and even recognition from the DOE secretary that his perception of the role of hydrogen has not been based on the latest developments

Principal investigators presented the status and results of their hydrogen and fuel cell projects at the 2012 Annual Merit Review meeting: links to their presentations and posters are provided below. Presentations and posters are grouped by topic and subtopic where applicable and appear in the order in which they were presented within those categories. The proceedings can be downloaded at the DOE website.
