“…Alternatively, liquid organic hydrogen carriers (LOHCs), hydrogen-rich materials such as formic acid, aqueous formate salts, methylcyclohexane, perhydrocarbazole, and perhydro dibenzyl toluene, with a volumetric hydrogen density of 30–60 kg H 2 /m, − are a potential solution, as long as they are reversible, nontoxic, thermally stable for extended periods of time, and can compete economically with incumbent technology . An LOHC system requires a storage medium (preferably a liquid H 2 carrier) and an efficient catalyst to release H 2 from the carrier at rates sufficient to meet the power demand of a particular use case (Scheme ).…”

In this work, we describe the benefits and challenges of a green approach to seasonal energy storage using ethanol as a liquid organic hydrogen carrier (LOHC). We evaluate the cycling efficiency of hydrogen release from ethanol (EtOH) to form ethyl acetate (EtOAc) as the spent LOHC and the subsequent regeneration of EtOH from EtOAc catalyzed by a single molecular catalyst, Ru-MACHO, at a moderate pressure of H 2 , mild reaction temperature, and high selectivity. From experimental and computational studies, we were able to minimize catalyst deactivation, regenerate the active catalyst post reactions, and establish the energy profile of the deactivation pathway relative to the on-cycle pathway catalyzed by Ru-MACHO. Based upon these findings, we performed a reactor design analysis to determine the footprint of an EtOH-based storage system to provide 85 MWh of energy by storing 5 metric tons (MT) of H 2 . We conclude that the heating and cooling required to maintain H 2 partial pressure present a significant engineering challenge for widespread deployment of this system.

“…On the other hand, from the MG structure point of view, most studies have tended to focus on battery energy storage systems (BESSs) to back up the variable renewable energy supplies [20]. Although BESSs are widely envisioned for long-term (seasonal) energy storage applications in an implicit fashion (since usually no provision is made to avoid the long-term storage of energy), most types of them are ineffective for seasonal energy storage due to their high self-discharge rates, especially if they are placed under high stresses [21]. In addition, the types of BESSs that are associated with lower self-discharge rates (typically lead-acid (LA) batteries) are, indeed, not as clean as they are often conceived.…”

“…The technical facilities and technologies used at the Johann Gregor Mendel Station and the main components of the energy system were reported in detail in [11]. A distribution model of a hybrid energy system for the power network of Syowa Station and the use of an exhaust heat pump to maintain the load factor of the engine generator at a high level during periods of green energy fluctuations were proposed [12][13][14]. Wasa Station developed a system of 48 solar panels to meet most of its operational power needs of [15].…”

A large number of research stations have been established to provide members of Antarctic expeditions with logistical support. A previous study confirmed that the wind and solar energy resources of the Chinese Zhongshan Station, a coastal station located in an area of Lassmann Hills in East Antarctica, are highly synergetic and complementary. Considering the demand for a renewable energy power supply in Zhongshan Station, this paper introduces a hybrid energy system with wind–solar–diesel–battery co-generation used as a power supply scheme. Based on the 2015 climate data for Zhongshan Station, the wind–solar resources, conventional energy system, and annual diesel consumption of the station area were analyzed. The annual electrical load demand of each building in the station area was quantitatively expounded. Compared with the original power supply system, and combined with the analysis results of the thermal load and electrical load demands of the station, an objective function based on the requirements of economy, reliability, and environmental protection was presented. According to the constraint conditions of the heat energy and electrical energy load balance in the station area, a multi-objective scheduling strategy for the system was designed. Finally, the effects of this scheduling strategy were analyzed under three different application scenarios. The results indicated that the annual load demand was significantly lower than before the scheduling, and that a 50% reduction in diesel consumption could be achieved, demonstrating that the multi-objective scheduling strategy proposed in this paper could achieve optimal energy scheduling and management of the renewable hybrid energy system.
