Global warming has become a challenge to the world; the challenge can be separated into two different perspectives: the feasibility of limiting warming to 1.5 °C and how we can adapt to its consequences. This low feasibility of limiting the temperature is an effect of several problems. The main problem is GHG, such as CO2 emissions, which increased to 40.8 Gt of CO2eq in 2021. Temperature increases and higher air pollutants are an effect of global warming. Energy transition into a non-carbon fuel becomes a promising solution. One of the solutions is hydrogen energy. The reason behind this is that hydrogen has a higher energy density. Hydrogen production is highly needed to serve its energy demand. TRCL technology has become the most brilliant idea for the hydrogen production process. This processes can produce hydrogen, thermal energy from fuel combustion, and carbon capture of high CO2 purity. These three parameters can be obtained simultaneously in the circulating mechanism, without NOx, that becomes a emmision. Also, metal oxide circulation plays a significant role in those productions. In this research, the main objective is to design the hydrodynamic analysis of oxygen carrier solid circulation in TRCL. Based on research that has already been conducted, the solid circulation rate is achieved in several configurations for Three Reactor Chemical Looping with a heat capacity of 50 kWth. The SCR value of 58.33 g/s is satisfied in module 1 for diameter size and bed inventory variations at the specific volume flow rate, configurations must exceed 90 LPM for an inventory of 1000 grams. There are two out of three configurations that satisfied this number for module 2, with a side aeration of 5 LPM at the recycle chamber 13 LPM. The looping system experiment validates these result values in a modular system.
