Energy storage strategy analysis based on the Choquet multi-criteria preference aggregation model: The Portuguese case

With the increase in renewable energy generation and its problems related to output instability, storage systems must be implemented in parallel to account for this effect. Therefore, it is valuable to deepen the study of these technologies’ performances in their several application tiers, thus understanding the potential of each alternative, both per tier and as a whole. For this reason, a collaborative multi-criteria decision-aiding framework is proposed to rank the various available options in several layers of the energy storage market, constructed alongside experts and policy-makers from each tier that serve as actors of the decision-making process and using Portugal as a case study. Based on the Choquet multi-criteria preference aggregation model, to the best of the authors’ knowledge, this framework is an unprecedented application in the energy sector. Beyond a critical review of the results, a scenario analysis was performed to explore interesting future possibilities that may aid governments to make decisions in the search for an energy sustainable development. Chemical storage solutions, such as Hydrogen and Methane, as well as several electrochemical batteries, especially Lithium- and Nickel-based ones, were the standout energy storage solutions. Chemical storage was shown to have the desired characteristics for the Long-term grid tier. Meanwhile, batteries, including Redox Flow in the first case, have overperformed in the Microgrid and Mobility tiers. No standout solutions appeared in the Short-term grid tier. Unsurprisingly, the aforementioned chemical storage systems, batteries, and Hot Water have presented themselves as the most politically interesting technologies, due to their multipurpose uses and intrinsic characteristics.     

碳中和背景下基于企业转型的氢储能经济分析

为了探寻解决可再生能源弃能问题和实现企业碳中和的有效途径，构建风电、光伏-氢储能混合系统。在碳中和目标下，提出基于碳中和目标下的成本-效益模型，从寿命周期成本/效益、年度平均成本/效益和平准化能源成本/效益6个角度出发，研究氢储能的经济性。结果表明，风电、光伏-氢储能系统的年度平均效益和平准化能源效益较好，系统建设方案可行，可为后续的企业能源结构调整提供可行方案。
