The future of renewable energy storage at sea

Offshore wind farms do not supply a constant amount of energy, which means we need a flexible energy system. A possible way to achieve this is storing energy at sea. For this purpose, the ALPHEUS project is looking into the possibilities of hydroelectric power stations.

On 14 March 2024, the partners in the ALPHEUS project are organising the webinar "Exploring the Future of Renewable Energy Storage in the Seas". During this webinar you will receive more information about the potential of pumped hydropower for energy storage from a panel of international experts.


The following topics will be addressed during the webinar:

  • Pump turbine test setups
    Videos ideos showcasing new test setups incorporating main data results
  • Conceptual design of dike and powerhouse
    The technology’s offshore placement – innovative low-head pumped hydro energy storage designs
  • Costs and revenues
    Life cycle assessment (LCA) of the low-head pumped hydro storage system designed by ALPHEUS


  • Stuart Reigeluth (REVOLVE);
  • Peter Hoffman (HoPe Energy Consulting); 
  • Jeremy Bricker (Delft Technical University); 
  • Ann Overmeire (Blue Cluster); 
  • Bettina Geisseler (Geisseler Law); and 
  • Anton J. Schleiss (Hydropower Europe).

Practical information

The webinar 'Exploring the Future of Renewable Energy Storage in the Seas' takes place on 14 March 2024 from 2 pm onwards and is broadcast via Zoom. The event is in English.

This event is open to members and non-members of Blue Cluster. Participation is free of charge. Prior registration is required.

About the ALPHEUS project

The ALPHEUS project (Augmenting grid stability through Low-Pumped Hydro Energy Utilization and Storage) strives to improve grid stability by converting energy into hydropower. The project partners specifically focus on low-head pumped hydro storage.

The project receives funding from the European Union within the scope of the Horizon 2020 programme and has a € 5 million budget. Blue Cluster is a member of the project's external advisory board
