Published at Chemical Engineering Journal – Thermodynamic modeling of countercurrent chemical looping reverse water gas shift process for redox material screening

Abstract: The reverse water gas shift (RWGS) reaction is a key pathway for CO2 utilization, particularly within Power-to-X process chains aimed at sustainable fuel and chemical production. Countercurrent chemical looping (CL-RWGS) using non-stoichiometric oxides can overcome equilibrium limitations of conventional RWGS reactors, enabling significantly higher CO2 conversions. However, modeling the limiting performance of such systems …

Published at Applied Thermal Engineering – A technology review of pumped thermal energy storage based on CO2 cycles

Abstract: Pumped thermal energy storage (PTES) is an innovative physical energy storage technology that converts surplus electricity into heat, stores it in thermal reservoirs, and reconverts it into electricity when needed. When CO2 is employed as the working fluid, PTES can offer advantages of potentially high round-trip efficiency, compact system equipment, and good operational flexibility …
