In order to compensate for the volatility of the feed-in of electricity due to the increasing share of renewable energy sources in the electrical grid, the capacity and duration of energy storage need to be increased by orders of magnitude. Among the different options, storage in the form of chemical energy has the advantage of high density and capacity. In this context, along with hydrogen and hydrocarbons, ammonia is attracting increasing interest as a possible energy vector. Its thermodynamic properties are close to those of propane. In the liquid state under close to environmental conditions, it has a higher energy density than hydrogen, and it is usable as a fuel in combustion engines and gas turbines. Currently, nearly all ammonia is produced by the Haber–Bosch-process optimized for continuous mass production; however, optimization for dynamic production seems to be not out of reach. At the laboratory scale, different potentially highly flexible electrochemical routes for ammonia synthesis and conversion to electricity are currently under investigation. This chapter reviews different options for ammonia synthesis and energy recovery under the premise of its use as a storage medium in a renewable energy system.
