High-intensity electrical catalyst heating was proved to be considerably more efficient compared to electrical heating with lower power and a longer heating period. Fuel injection was also found to be beneficial to reduce the NO x emissions when the DOC''s temperature was higher than 250 °C, as the tested DOC was able to oxidise most of the …

1 Introduction. Thermal energy storage (TES) in the form of chemical energy, also called termochemical TES, represents a valid alternative to the traditional sensible and latent TES due to higher storage density, longer storage time with lower thermal dissipation [ 1 ]. Thermochemical TES is realized performing a reversible …
