“…Integrated systems show promising alternatives in effective carbon capture by recovering possible waste streams into useful products such as heat, cooling, and hydrogen. The chemical looping hydrogen production system developed by Zhang et al succeeded to reach an overall efficiency of 59.8% with zero emissions which is significantly higher than 40% reported by McGlashan .…”

“…Wolf and Jan proposed a novel CLC configuration for heat, power, and hydrogen production. A comprehensive thermodynamic analysis of CLC conducted by McGlashan showed that integrated with fuel cells, a CLC plant can reach efficiencies above 40%. A three‐stage Rankine cycle with zero emissions is proposed by Chen et al , where a CLC and SOFC are combined.…”

This paper focuses on clean energy solutions in order to achieve better sustainability, and hence discusses opportunities and challenges from various dimensions, including social, economic, energetic and environmental aspects. It also evaluates the current and potential states and applications of possible clean-energy systems. In the first part of this study, renewable and nuclear energy sources are comparatively assessed and ranked based on their outputs. By ranking energy sources based on technical, economic, and environmental performance criteria, it is aimed to identify the improvement potential for each option considered. The results show that in power generation, nuclear has the highest (7.06/10) and solar photovoltaic (PV) has the lowest (2.30/10). When nonair pollution criteria, such as land use, water contamination, and waste issues are considered, the power generation ranking changes, and geothermal has the best (7.23/10) and biomass has the lowest performance (3.72/10). When heating and cooling modes are considered as useful outputs, geothermal and biomass have approximately the same technical, environmental, and cost performances (as 4.9/10), and solar has the lowest ranking (2/10). Among hydrogen production energy sources, nuclear gives the highest (6.5/10) and biomass provides the lowest (3.6/10) in ranking. In the second part of the present study, multigeneration systems are introduced, and their potential benefits are discussed along with the recent studies in the literature. It is shown that numerous advantages are offered by renewable energy-based integrated systems with multiple outputs, especially in reducing overall energy demand, system cost and emissions while significantly improving overall efficiencies and hence output generation rates.

“…The production of H 2 is important for many reasons, some of which are longer-term, such as introducing the H 2 economy, possibly with the use of fuel cells and encompassing the transportation industry (McGlashan, 2010;Scott, 2008) rather than just stationary power sources or industrial processes as are the bulk of examples considered in this chapter. However, H 2 itself is an important chemical produced in large amounts (on the order of 50 Mt/a (USDOE, 2013b)) and is of profound interest to some national economies, such as in Canada for oil sands upgrading, where current needs are around 1 Mt/a but have been predicted to rise to 7.7 Mt/a by 2030 (Larsen et al, 2004;National Energy Board, 2014).…”

“…Hydrogen is crucial in the so-called hydrogen economy [3]-in which many applications of this chemical have been found in important industry branches. Besides using it directly as a fuel-either in fuel [7,8] combustion [9], hydrogen is the key ingredient of ammonia synthesis [10] or important from the environmental protection point of view hydrogenation reactions [11][12][13], including CO 2 hydrogenation [14].…”

We present the analysis of the stability of the (TiO2)n nanoclusters, where n = 2–4, supported on the Fe3O3-hematite (100) surface. The analysis is focused on the size and geometry of the nanocluster, which defines the contact with the supporting hematite surface. The aim of the work is to explore the role of the interaction within the nanocluster as well as between the nanocluster and the surface in the structure of the composite system. We have used an in-house developed variant of the solids docking procedure to determine the most stable initial configurations of the nanoclusters with respect to the surface. Subsequently, we have carried out molecular dynamics simulations to enable finding a more stable configurations by the systems. The results show the three possible binding modes for the (TiO2)2 systems, but many more such modes for the larger clusters. Additionally, we have found that the partial dissociation of the nanocluster takes place upon the contact with the surface.
