Recent studies have indicated the potential of a contra-rotating pump-turbine (CRPT) as a low-head design that enables pumped hydro storage in regions with flat topography. However, the effects of cavitation have scarcely been investigated for the CRPT. The current paper utilises computational fluid dynamics simulations to study a model scale CRPT subjected to cavitating […]

NEW PUBLICATION: Design of shaft- and rim-driven contra-rotating reversible pump-turbine to optimize novel low-head pumped hydro energy storages
According to the European-Green-Deal, the share of renewable energy sources (RES) in electricity generation is increased by e.g. solar/wind. This requires the deployment of effective energy storage solutions to compensate the fluctuating network supply of RES. A well-developed storage technology is pumped hydro energy storage (PHES), but especially in lowland countries, e.g. Denmark, typical […]
New Publication: Axial Flux PMSM Power Take-Off a Rim-Driven Contra-Rotating Pump-Turbine
Pumped hydropower storage (PHS) is a costeffective and mature energy storage technology. However, it has inherently been limited to locations with suitable topographies. Therefore, the ALPHEUS project aims to implement PHS for shallow seas and coastal environments with the goal to support grid stability. To ensure optimal efficiency and fast switching times in these low-head […]
