Title:            An Experimental Study of Heating Recovery from Engines Exhaust based on
Hydrogen Storage System
Authors:       Minh Man Pham, Thi Hai Van Nguyen
Abstract:     In this research, a heating recovery is used for thermal energy storage from exhaust gas of the internal combustion engines for the purpose of storing hydrogen fuel. Inside the heat recovery, it is designed with multiple flaky layers that are arranged evenly with 60-degree angle to create the exhaust vortex flow as well as store the largest amount of heat for saving energy. The experiment is carried out with three different engine speeds through the corresponding load is the largest, smallest, medium mode and the flow rates of water heated in the fuel storage system are up to 2 LPM. After carrying out and analysis of the results obtained from the heat recovery, we found that the storage process is influenced significantly by the exhaust temperature as well as the motor speed and the rate of water flow; which also shows that the heat recovery served for heating and hydrogen fuel storage has high energy efficiency and good heat transfer capability of the entire system thanks to its special structure.
