    The CaO/Ca(OH)2 system can be the basis for cost-efficient long-term energy storage, as the chemically stored energy is not affected by heat losses, and the raw material is cheap and abundantly available. While the hydration (thermal discharge) has already been addressed by several studies, for the dehydration (thermal charge) at low partial steam pressures, there is a lack of numerical studies validated at different conditions and operation modes. However, the operation at low steam pressures is important, as it decreases the dehydration temperature, which can enable the use of waste heat. Even if higher charging temperatures are available, for example by incorporating electrical energy, the reaction rate can be increased by lowering the steam pressure. At low pressures and temperatures, the limiting steps in a reactor might change compared to previous studies. In particular, the reaction kinetics might become limiting due to a decreased reaction rate at lower temperatures, or the reduced steam density at low pressures could result in high velocities, causing a gas transport limitation. Therefore, we conducted new measurements with a thermogravimetric analyzer only for the specific steam partial pressure range between 0.8 and 5.5 kPa. Based on these measurements, we derived a new mathematical fit for the reaction rate for the temperature range between 375 and 440 °C. Additionally, we performed experiments in an indirectly heated fixed bed reactor with two different operation modes in a pressure range between 2.8 and 4.8 kPa and set up a numerical model. The numerical results show that the model appropriately describes the reactor behavior and is validated within the measurement uncertainty. Moreover, our study revealed an important impact of the operation condition itself: the permeability of the reactive bulk is significantly increased if the dehydration is initiated by a rapid pressure reduction compared to an isobaric dehydration by a temperature increase. We conclude that the pressure reduction leads to structural changes in the bulk, such as channeling, which enhances the gas transport. This finding could reduce the complexity of future reactor designs. Finally, the presented model can assist the design of thermochemical reactors in the validated pressure and temperature range.

    Abstract

    The calcium oxide/water/calcium hydroxide system is a promising material system for thermochemical energy storage (TCES). Its high reactivity under various experimental conditions during the cyclic operation of heat storage‐and‐release is a key challenge for practical applications. In this study, we developed a new type of highly durable TCES medium with hydration reactivity enhancement. The composite materials were prepared by heat treatment of a mixture of calcium carbonate and additives, consisting of tetraethoxysilane (TEOS) and a silane coupling agent, bis(3‐triehoxysilylpropyl) pertetrasulfide (SCA). The kinetic performances of the composites and CaO were compared. It was observed that the additives promoted hydration reactivity at 450°C and 70 kPa, and 0.6 wt% composite exhibited the highest thermal output. Furthermore, it was found that the enhancement in hydration reactivity was affected by the experimental conditions as significant enhancements were observed when the experimental conditions were closer to equilibrium, while almost no enhancement was observed when the conditions were far from equilibrium or at a high vapor partial pressure. Sample characterization via X‐ray diffractometry and scanning electron microscopy revealed that the agglomeration of CaO particle grains was alleviated by pinning effects, and the component that enhanced the hydration reactivity was identified as Ca2SiO4 nanoparticles.

    Abstract

    Thermochemical energy storage using a calcium oxide/calcium hydroxide/water (CaO/Ca(OH) 2 /H 2 O) reaction system is a promising technology for thermal energy storage at high‐temperatures (400°C‐600°C). The purpose of this study is to develop a practical composite material by enhancing heat transfer through the reaction bed and mitigating problems of pure CaO/Ca(OH) 2 materials, such as formation of centimeter‐scale agglomerates and change in the bulk volume during repetitive reactions. The present study focused on a novel composite material using a silicon carbide/silicon (SiC/Si) foam. In the literature, performance of thermochemical energy storage of the composite using the ceramic foam remains unclear. In this study, we evaluated the performance of the composite material (~63 g) by a 100‐W‐scale packed bed reactor. The volumetric heat output rate (for the first 5 minutes, under maximum hydration pressure) of the composite was 1.3 kW L‐bed −1 , which was 1.4 times higher than that previously reported for a bed of pure Ca(OH) 2 pellets. The composite material, in which the CaO/Ca(OH) 2 samples were subdivided inside pores with a mean diameter of 400 μm, retained high reactivity during cycle reactions, and maintained its bulk volume. Therefore, the composite material developed in this study shows promising application for high‐temperature thermochemical energy storage.

    Abstract

    Thermochemical energy storage (TCES) using reversible gas‐solid reactions is a promising technology owing to the high energy density and capability of long‐term storage. TCES using a calcium oxide/calcium hydroxide/water (CaO/Ca(OH)2/H2O) reaction system has attracted considerable attention because of the low material cost and environmental friendliness of the reactants. Previous experimental studies have focused on the TCES performances of packed beds of calcium oxide/calcium hydroxide powder. However, pelleted materials can be more favorable than powdered materials from a practical viewpoint. The aim of this study is to evaluate the performance of TCES of a packed bed of calcium oxide/calcium hydroxide pellets. In this work, a total of 60 g of calcium hydroxide pellets (diameter of 1.9 mm and length of 2‐10 mm) was evaluated using a 100‐W scale packed bed reactor. The heat storage density of the bed was 1.0 MJ L‐bed−1, and an average heat output rate of 0.71 kW L‐bed−1 was observed for the first 10 minutes under a hydration pressure of 84.6 kPa. The stability of the reaction conversion of the bed was demonstrated during 17 cycles of experiments.

    太陽光、風力などの再生可能エネルギー(再エネ)は出力変動が多く、需要との不一致の際に出力抑制が発生しており、再エネ利用の妨げになっている。今後の再エネの大幅な導入には蓄エネルギー(蓄エネ)の強化が必要である。電池が候補であるが、より低コストな蓄エネ方法としてP2H2P(Power-to-Heat-to-Power、電力蓄熱発電)に可能性がある。P2H2Pのポイントは高効率な蓄熱である。化学蓄熱は従来の潜熱、顕熱蓄熱を越えた高密度、長期蓄熱が可能である。そこで、化学蓄熱性能を有したケミカルヒートポンプ(CHP)を開発する。酸化カルシウム/水系CHPの課題は材料の耐久性と高熱伝導度化であったが、本研究では繰り返し耐久性と高伝熱性を備えた複合材料を開発した。この材料により、従来困難であった500°Cの熱源を蓄熱し、600°Cに昇温できるCHPの実証を行う。P2H2Pの効率向上と普及に貢献できると期待できる。
