| Sumario: | This project explores the feasibility of using hydrogen in an Energy Storage System (ESS) in conjunction with Renewable Electricity Sources (RES) systems for small-scale households or communities. It aims to study the economic potential of a hydrogen energy storage system (HESS) as a replacement for the Battery Energy Storage System (BESS). The latest developments in hydrogen technologies and battery packs are demonstrated and discussed. Key differences are compared from recent literature. The electrolysers, compressors, hydrogen tanks, and fuel cells in the hydrogen system are discussed individually. The choice of battery type is the main discussion for the battery system. A simple mathematical method is thus established to compare the costs of applying hydrogen and batteries in ESS of different scales. Both capital costs (CAPEX) and operational costs (OPEX) are considered, and the lifetime difference is also taken into consideration. The ESS is assumed to be set for a building(s) or a small community with renewable energy sources (RES) and aims to help the system be more efficient. Another process is carried out to forecast prices for 2025, 2030, and 2050. It shows the costs of the HESS and the BESS for the same purpose and scale in the future. This is to assess the economic competitiveness in the future market and evaluate the feasibility of HESS installation. The result of the first part shows that the HESS is not very competitive on regular demand occasions. However, in an extreme ratio of C/P demand, the HESS may be more economical than the BESS. The result of the second part shows that the HESS is more affordable than the BESS in the future. This trend is expected to start in 2025 and continue until at least 2050. The lead of the HESS is not very significant, so the BESS is still competitive in the market. This study provides insight into the feasibility of HESS, both currently and in the future. It is recommended that people install HESS in their residential buildings. It is predicted that hydrogen will become increasingly common, and everyone will have the opportunity to profit from it by installing a hydrogen system and becoming a prosumer. |
