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

A recent scientific study indicates that hydrogen gas is seeping from within the Earth in places where historically no one had expected it before.

Scientists have now identified thousands of sites in the European part of Russia where natural hydrogen gas may be found seeping out of shallow depressions. In research paper, published in Natural Resources Research , scientists have examined many of these subcircular, shallow surface depressions seeping hydrogen gas, ranging in size from a hundred meters to several kilometers in diameter. These have been identified throughout a region extending from the Moscow region to Kazakhstan.
Using portable gas detectors, researchers found the concentration of molecular hydrogen gas in the soil of these structures was very high, up to 1.25% at 1.2 m deep.
