Closed Loop Thermochemical Energy Storage System Using Ammonia - Australian National University
"A fixed amount of reactants (ammonia, nitrogen and hydrogen) are contained in a closed loop, and pass alternately between energy storing and energy releasing reactors with provision for storage of reactants in between. Because the solar energy is stored in a chemical form at ambient temperature, there are zero energy losses in the store regardless of the length of time that the reactants remain in storage. The reactors are packed with standard commercial catalyst materials to promote both reactions. Counter-flow heat exchangers transfer heat between in-going and out-going reactants at each reactor to use the energy most effectively."
