Review of pressurized chemical looping processes for power generation and chemical production with integrated CO2 capture
Chemical looping has great potential for reducing the energy penalty and associated costs of CO2 capture from fossil fuel-based power and chemical production while maintaining high efficiency. However, pressurized operation is a prerequisite for maximizing energy efficiency in most proposed chemical...
Finding synergy between renewables and coal: Flexible power and hydrogen production from advanced IGCC plants with integrated CO2 capture
Variable renewable energy (VRE) has seen rapid growth in recent years. However, VRE deployment requires a fleet of dispatchable power plants to supply electricity during periods with limited wind and sunlight. These plants will operate at reduced utilization rates that pose serious economic...

CFD Simulations of an Additional H2 Combustor for Improving Efficiency in Chemical Looping Combustion Power Plants
Experimental demonstration of pressurized chemical looping combustion in an internally circulating reactor for power production with integrated CO2 capture
This study presents an experimental demonstration of pressurized chemical looping combustion (CLC) in an internally circulating reactor (ICR). The ICR concept is a novel alternative to the conventional interconnected fluidized bed CLC configuration as it eliminates all cyclones, loop seals and...
Demonstration of the novel swing adsorption reactor cluster concept in a multistage fluidized bed with heat-transfer surfaces for postcombustion CO2 capture
Efficient Production of Clean Power and Hydrogen Through Synergistic Integration of Chemical Looping Combustion and Reforming
Chemical looping combustion (CLC) technology generates power while capturing CO2 inherently with no direct energy penalty. However, previous studies have shown significant energy penalties due to low turbine inlet temperature (TIT) relative to a standard natural gas combined cycle plant. The low TIT...
Integration of chemical looping combustion for cost-effective CO2 capture from state-of-the-art natural gas combined cycles
On capital utilization in the hydrogen economy: The quest to minimize idle capacity in renewables-rich energy systems
The hydrogen economy is currently experiencing a surge in attention, partly due to the possibility of absorbing variable renewable energy (VRE) production peaks through electrolysis. A fundamental challenge with this approach is low utilization rates of various parts of the integrated electricity...
