Thermochemical energy storage and transport system utilizing zeolite steam adsorption and desorption cycle is one of the methods to resolve the mismatch between industrial surplus heat and heat demands. To generate 60°C hot water utilizing zeolite 13X, zeolite boiler employing moving bed and indirect heat exchanger was developed. Pressurized water is heated up and flash steam is injected into the zeolite bed for adsorption. A quasi - 2D model solving heat and mass conservation equations was developed, leading to a performance characterization of this zeolite boiler. The developed simulation model was used to predict performance of a heat charging device employing moving bed as well. Based on this calculation, a case study, heat transporting between a local steel works and a hotel was examined and all corresponding cost were fixed. The Levelized Cost of Energy (LCOE) results in around 60 €/MWh which is comparable cost against conventional pellet boiler. Sensitivity analysis showed both of cheaper transportation cost and larger zeolite capacity on the one trailer give a comparable impact on the LCOE.
