“…The process is benchmarked with state-of-the-art autothermal reforming (ATR). 45 A schematic diagram of the GSDR–MeOH process integration is shown in Figure 11 . The GSDR part consists of three stages (reduction, reforming, and oxidation), and the process starts with the reduction stage ( Figure 11 ) where the unconverted gas from a GTL process is utilized (recycled) to reduce NiO to the metallic state (Ni).…”

This further investigates the concept of gas switching dry reforming (GSDR) that efficiently converts the two major greenhouse gases (CO 2 and CH 4 ) into a valuable product (syngas) for gas-to-liquid (GTL) syntheses. The proposed GSDR is based on chemical looping technology but avoids external circulation of solids (metal oxides) by alternating the supply of reducing and oxidizing gas into a single fluidized bed reactor to achieve redox cycles. Each cycle consists of three steps where a metal oxide/catalyst is first reduced using GTL off-gases to produce CO 2 (and steam) that is supplied to the next reforming step to produce syngas for GTL processes. The metal oxide is then reoxidized in the third step associated with heat generation (through the exothermic oxidation reaction of the metal oxide and air) to provide the heat needed for the endothermic dry methane reforming step. Experimental demonstrations have shown that a syngas H 2 /CO molar ratio between 1 and 2 suitable for methanol production could be achieved. A further demonstration shows that pressure has negative effects on gas conversion. Following the successful experimental campaign, process simulations were completed using ASPEN to show how the GSDR process can be integrated into a methanol (MeOH) production plant.

“…H 2 can also be used as a promising solution for a multi-sectorial decarbonization as it allows to link between the green and blue H 2 production systems and the other energy sectors (industry, transport, and natural gas system) (Burandt et al, 2019;Helgeson and Peter, 2020;Tlili et al, 2020). The production of large-scale green and blue H 2 will more energy efficient and economical viable if integrated processes are applied (Gençer and Agrawal, 2017;Lee et al, 2019;Spallina et al, 2019;Mosca et al, 2020).…”

Low carbon hydrogen can be an excellent source of clean energy, which can combat global climate change and poor air quality. Hydrogen based economy can be a great opportunity for a country like Qatar to decarbonize its multiple sectors including transportation, shipping, global energy markets, and industrial sectors. However, there are still some barriers to the realization of a hydrogen-based economy, which includes large scale hydrogen production cost, infrastructure investments, bulk storage, transport & distribution, safety consideration, and matching supply-demand uncertainties. This paper highlights how the aforementioned challenges can be handled strategically through a multi-sector industrial-urban symbiosis for the hydrogen supply chain implementation. Such symbiosis can enhance the mutual relationship between diverse industries and urban planning by exploring varied scopes of multi-purpose hydrogen usage (i.e., clean energy source as a safer carrier, industrial feedstock and intermittent products, vehicle and shipping fuel, and international energy trading, etc.) both in local and international markets. It enables individual entities and businesses to participate in the physical exchange of materials, by-products, energy, and water, with strategic advantages for all participants. Besides, waste/by-product exchanges, several different kinds of synergies are also possible, such as the sharing of resources and shared facilities. The diversified economic base, regional proximity and the facilitation of rules, strategies and policies may be the key drivers that support the creation of a multi-sector hydrogen supply chain in Qatar.

“…The ammonia production cost estimated was ~5% less than the reference plant with negative CO2 avoidance cost (-5 $/tonCO2). A similar setup of three dynamically operated packed-bed reactors was also used for methanol production by Spallina et al [154]. In this process, the reactors were operated at a pressure above 25 bar.…”

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 looping configurations, introducing significant complexities related to system design, operation and scale-up. Understanding the effects of pressurization on chemical looping systems is therefore important for realizing the expected cost reduction of CO2 capture and speed up the industrial deployment of this promising class of technologies.This paper reviews studies that investigated three key aspects associated with pressurized operation of chemical looping processes. First, the effect of pressure on the kinetics of the various reactions involved in these processes was discussed. Second, the different reactor configurations proposed for chemical looping were discussed in detail, focusing on their suitability for pressurized operation and highlighting potential technical challenges that may hinder successful operation and scale-up. Third, techno-economic assessment studies for these systems were reviewed, identifying the process configuration and integration options that maximize the energy efficiency and minimize the costs of CO2 avoidance.Prominent conclusions from the review include the following. First, the frequently reported negative effect of pressure on reaction kinetics appears to be overstated, implying that pressurization is an effective way to intensify chemical looping processes. Second, no clear winner could be identified from the six pressurized chemical looping reactor configurations
