Ammonia (NH 3 ) could become an alternative solution to allow the required hydrogen to be stored and transported with ease. In comparison to hydrogen, liquefied ammonia makes it easier to transport large volumes to wherever it is needed. It can be converted into hydrogen right at the filling station using decentralized plants.

The basic concept of power-to-gas (or e-Gas, as Audi calls it), is to “store” excess renewable electricity by producing hydrogen, which can then either be converted to methane; injected into the gas distribution grid directly; or used as a vehicle fuel. Scientific partners will participate in the operational phase.

When a voltage is applied across the electrodes of a conventional cell, a current flows and water is converted to oxygen gas at one electrode (the anode) and hydrogen gas at the other electrode (the cathode).
