The integration of renewable energy with latent thermal energy storage systems (LHTESS) using phase change materials (PCMs) provides an effective solution to climate change challenges and fossil fuel limitations. This work provides a numerical analysis of PCM performance in LHTESS equipped with innovative fin configurations. The melting process is modeled using finite volume method combined with the enthalpy-porosity approach with RT35 as PCM, and water as heat transfer fluid. Various Y-shaped fin configurations are examined by altering the branch angles, trunk lengths, and number of fins, while maintaining total fin material volume under 2 % of the overall PCM volume. Findings show that the optimal Y-fin configuration features a 2 mm trunk length and 60° branch angle. Increasing fin numbers reduces charging time but increases fin material usage. While Case 15 achieves the highest charging power and fastest charging time, it offers minimal material savings. Conversely, Case 12 represents a well-balanced design, achieving a significant 23 % reduction in material usage, notable power storage of 74 W, and over 20 % savings in charging time. The study provides meaningful understanding into improving LHTESS thermal performance while optimizing material usage. These findings contribute to developing advanced LHTES designs that deliver higher efficiency and support sustainable energy solutions.
