Summary: Chemical looping steam reforming (CLSR) using oxygen carriers (OCs) has been demonstrated as an efficient technology for hydrogen production. In this study, NiO/MgAl2O4 OCs were employed for hydrogen production via CLSR with and without CaO sorbent for in-situ CO2 removal (SE-CLSR). The optimal temperature for hydrogen production was found to be 650°C, and the 1g 20NiO/MgAl2O4 catalysts showed high hydrogen selectivity and minimal 'dead time'. High purity hydrogen was successfully obtained via CLSR coupled with CaO sorbent, and stable hydrogen production was achieved with modified stability SE-CLSR experiments.

Summary: This study conducts a comparative techno-economic analysis of adding CO2 capture technologies to existing oil shale power plants in Estonia. The results show that oxy-fuel combustion capture performs better than post-combustion capture, but it leads to a reduction in power plant efficiency. The feasibility of CO2 capture in Estonian oil shale power plants depends on long-term trends in the electricity market and CO2 emissions trading system, and it may require state aid, which could reduce the overall competitiveness of the Estonian economy.

Summary: In this study, an effective approach for converting CO2 using the electrified combined reforming reactor (E-CRM) was developed. The process was simulated and assessed using Aspen Plus software, and the results showed that electrification significantly improved the overall efficiency of the process. Key factors such as hydrogen demand, net electricity consumption, thermal efficiency, and methanol production were all improved. Additionally, a life cycle assessment (LCA) was conducted using openLCA software, and the results demonstrated that the E-CRM with 90% recycling of unreacted gases was the most environmentally attractive option, with the lowest greenhouse gas emissions, when the carbon intensity of the electricity was equal to or lower than the average value in Canada.

Summary: The use of ammonia as a hydrogen carrier can be improved with the use of a membrane reactor, which allows for ammonia decomposition and hydrogen separation in one device, providing efficiency and compactness advantages. Ceramic-supported double-skinned Pd-Ag membranes have shown excellent performance for hydrogen separation but suffer from sealing and mechanical stability issues. To overcome these limitations, metallic supported Pd-based membranes are suggested. In this study, a Pd-Ag membrane was prepared on a low-cost metallic support and tested for ammonia decomposition in a membrane reactor, achieving high NH3 conversion and H2 recovery rates. These results indicate potential as a substitute for ceramic-supported alternatives.

Integration of the dynamic system formed by the reactor and the power plant is investigated for decarbonization of energy production and storage of renewable energy. Different case studies are assessed, and gas turbines in various power plant architectures are investigated. The use of biogas during the energy charge stage is found to be advantageous, leading to negative CO2 emissions.

Summary: This study investigates heat and mass transfer phenomena in a packed bed (membrane) reactor for the direct conversion of CO2 to DME. Intra-particle diffusion limitations and concentration polarization were found to affect the reactor performance. Correlations were developed to account for these phenomena and showed high accuracy in predicting the reaction performance. Other phenomena such as intra-particle heat transfer, particle-fluid mass and heat transfer, and axial dispersion had negligible effects on the reactor behavior. The study proposes reactor optimization strategies based on the observed transfer phenomena.

Summary: The spatial profile of a gliding arc reactor for NO(x) synthesis was analyzed using AC pulsed mode operation. Tests with a duty cycle of 40% or 60% achieved the lowest energy consumption of 6.95 MJ/mol, showing a 15% improvement compared to continuous operation. The reactor was divided into five zones along the arc propagation, with the first and last zones having higher energy consumption and the middle parts showing lower consumption. The analysis of plasma properties indicated nonuniformity, which corresponds to the NO(x) production performance across the reactor. This research provides insights for understanding and optimizing gliding arc reactors for efficient nitrogen fixation.
