Abstract: Widespread adoption of renewable energy sources such as solar and wind power to reduce greenhouse gas emissions calls for supplementary green technologies for stabilizing a grid because of their intermittent nature. Pumped hydro storage (PHS) systems are a proven and reliable technology that can be used for this purpose. Traditionally hydro power systems require high head and so the potential installation sites are limited. A low head PHS system is very desirable for flat geographies where high head reservoirs are not possible. ALPHEUS project funded by the European Union’s Horizon 2020 program aims at developing a low head seawater PHS system for augmenting grid stability. To meet the requirements, a shaft driven contra-rotating reversible pump turbine is designed using inverse 3D blade design approach. Computational fluid dynamic analysis is performed in both pump and turbine modes of operation to assess the performance across a range of conditions. An optimization is carried out in the model scale using a Design of Experiments approach to maximize the performance. A laboratory model test will be carried out for the optimized design to validate the performance.
