Since June 2020, I am working at TU Braunschweig, Germany, as a PhD student within the EU's Horizon 2020 project ALPHEUS. My involvement is twofold. On the one hand I am designing a lab test setup, planning its construction and defining the data acquisition system for testing newly designed pump/turbines. On the other hand, I am performing a stakeholder analysis. My research interest are hydraulics, hydropower, energy generation and distribution, stakeholder analysis and project management.

- Pursuing a PhD degree within the ALPHEUS project funded by the EU's Horizon 2020 program. My role is twofold, on the one hand I am involved in the design and planning of the construction of a laboratory test. We will use this for performing test to the newly design counter rotating reversible pump turbines. Data adquisition will follow. On the other hand, I am performing a stakeholder analysis.

The pan‐European power grid is experiencing an increasing penetration of Variable Renewable Energy (VRE). The fluctuating and non‐dispatchable nature of VRE hinders them in providing the Ancillary Service (AS) needed for the reliability and stability of the grid. Therefore, Energy Storage Systems (ESS) are needed along the VRE. Among the different...
The energy transition requires large-scale storage to provide long-term supply and short-term grid stability. Though pumped hydro storage is widely used for this purpose, regions without natural topography do not have the potential for traditional high-head pumped hydro storage. To address this, multiple projects for low-head and seawater pumped hy...
The pan-European power grid is experiencing an increasing penetration of Variable Renewable Energy (VRE). The fluctuating and non-dispatchable nature of VRE hinders them in providing the Ancillary Service (AS) needed for the reliability and stability of the grid. Today’s grid is reliant on synchronous generators. In case of sudden frequency deviati...
ALPHEUS Augmenting grid stability through Low-head Pumped Hydro Energy Utilization & Storage With a growing share of intermittent renewable energy sources grid stability can be maintained, and flexibility enhanced, by applying pumped hydropower energy storage. ALPHEUS will improve reversible pump/turbine (RPT) technology and adjacent civil structures needed to make pumped hydro storage economically viable in shallow seas and coastal environments with flat topography. Three promising technologies will be considered: ● Shaft-driven variable-speed contra-rotating propeller RPT – avoiding guide vanes in a two-way device improves overall efficiency; ● Rim-driven variable-speed contra-rotating propeller RPT – rim driven configuration avoids the complexity of a shaft assembly, decreasing noise, vibrations, switching time, and maintenance costs; ● Positive displacement RPT – fish friendly and seawater-robust, low cost technology. ALPHEUS plans stepwise development, starting by validating current assumptions in the lab and optimizing efficiency with numerical simulations. Based on results, two of these technologies will be chosen and functionality will be demonstrated for working models under realistic circumstances. Finally, a reasoned and quantified assessment of these two technologies will be delivered for further development into full scale prototype. Combining current state-of-the-art and expertise of the partners ALPHEUS expects to reach round-trip RPT efficiency of 0.7 to 0.8. Fatigue resistance of mechanical and civil installations will be addressed, which occur with switching between pumping and turbining modes within 90-120 seconds. ALPHEUS will address environmental aspects, including fish friendliness, scenery and land use, juxtaposed with the ability of decentralized pumped hydro storage to stabilize the grid over a range of timescales and therefore allow higher penetration of intermittent renewable energy supplies. This will result in a methodology for assessing potential sites for pumped low-head and ultra-low head energy storage.
