The effect of heat released during CaO adsorption on sorption-enhanced steam methane reforming for hydrogen production is insufficiently understood. On this basis, Aspen Plus is used to study the effect of steam methane reforming on hydrogen production without/with CaO. At 700 °C and an O 2 inflow of 7 mol/h, the molar flow and molar percentages of H 2 are 20.62 and 67.35%. After adding CaO, at 700 °C with 4.5 mol/h of CaO, the heat release of CaO adsorption is 1.32 MJ/h, and the O 2 inflow reduces to 4.3 mol/h. The molar flow and molar percentage of H 2 are 22.80 mol/h and 85.94%. When 1.2 mol/h CH 4 is combusted for CaCO 3 decomposition in the calciner, regenerated CaO is transferred to the reforming reactor for calcium cycling, which consumes 2.4 mol/h of O 2 . For the entire cycle, 6.7 mol/h of O 2 .

“…Another use for sorption systems is the new, efficient method of generating hydrogen from biomass gasification and decarbonisation, as described by Zhang et al [25]. The method improves the hydrogen generation efficiency by 17.4% compared to conventional methods.…”

“…Heat and cold storage capabilities by salt or metal sorption have a high potential in theory, but due to the lower actual ability to fix water, their applicability is limited. The papers [20,[23][24][25][26] discuss methods for reducing this issue under certain specific conditions, such as a particular reaction environment, the addition of a new component, or a changed place where they are applied. Sorption systems provide an important potential for heat and cold storage at high volumes and high power, which has found practical application in industry.…”

This paper presents a detailed analysis of the research into modern thermal energy storage systems dedicated to autonomous buildings. The paper systematises the current state of knowledge concerning thermal energy storage systems and their use of either phase change materials or sorption systems; it notes their benefits, drawbacks, application options, and potential directions for future development. The rapid proliferation of studies on installation systems, new composites, and phase change materials requires a systematisation of the subject related to short- and long-term thermal energy storage in building structures. This paper focuses on assessing the validity of the current improved thermal energy storage solutions for buildings with very high energy efficiency standards and buildings that are energy-independent. The paper presents the current results of the energy and economic analyses of the use of heat storage systems in buildings. This paper shows the optimal heat storage systems for autonomous buildings. Moreover, it also shows other potential ways to develop systems and composites capable of storing heat in autonomous buildings.

“…One of the most emerging and developing techniques to separate CO2 from post-combustion flue gases is a second-generation calcium looping (CaL) technique, derived from chemical looping combustion technology [22], based on reversible CaO carbonation/regeneration [23,24]. In addition to CO2 adsorption, CaL has already been exerted for the biomass and methane reforming process, H2 production, and thermochemical energy storage [25][26][27]. Moreover, this process has been demonstrated as the most energyefficient and affordable technology for industrial decarbonization, among other developing CO2 capture processes.…”
