Kurzfassung

Das Konzept Buoyant Energy (BE) – eine Art schwimmendes Pumpspeicherkraftwerken (PSW) – wurde von Forschern der UIBK entwickelt (Patent angemeldet) und bietet die Möglichkeit, elektrische Energie direkt auf dem Wasser z.B. nahe an Offshore Windkraftanlagen zu speichern. Damit kann ein wichtiger Beitrag zum dezentralen Ausgleich von Stromangebot und -nachfrage und zur Integration volatiler, erneuerbarer Energien (EE) geleistet werden. Das grundlegende Konzept ist zwar einfach und skalierbar, jedoch erfordert die konkrete Realisierung des Stromspeichersystems noch umfassende Entwicklungsarbeiten. Diese sind: Ermittlung der optimalen Einsatzgebiete und Anwendungs-felder, Schwimmkörperdesign, Untersuchung maschinentechnischer Ausstattungen und Kombinationsmöglichkeiten von BE mit schwimmender Infrastruktur. Ziel der Sondierung ist es zu zeigen, dass das BE Konzept technisch und wirtschaftlich grundsätzlich zukunftsfähig ist, Entwicklungsziele mit besten Erfolgsaussichten zu definieren und damit Industriepartner für die Entfaltung des grünen Stromspeicher Know-hows im zukünftigen Umfeld regenerativ dominierter Stromnetze zu gewinnen.

Project abstract

In line with the work programme the project aims to develop a novel, very effective, highly available, very durable, sustainable and safe solution for distributed energy storage. Buoyant Energy is an offshore concept, which is based on the pumped hydro storage power technology. This technology will be transferred from mountainous regions to the sea.

The solution offers outstanding advantages compared to other emerging energy storage technologies. Those characteristics are very much linked to pumped hydro storage power systems. In contrast to those plants with an upper and a lower reservoir “Buoyant Energy” uses a smaller reservoir (buoyant platform) located within a larger reservoir (the sea). Due to the mass of the floating structure there is a water level difference. Water is moved from one reservoir to the other by means of pumps and turbines: to store energy, water from the smaller reservoir is pumped into the larger reservoir (the platform raises); to release energy, the structure is lowered and the inflow into the smaller reservoir powers a turbine. On top there are important synergies with other offshore activities to expect (e.g. facilitating the access and the operation for offshore wind farms).

Buoyant Energy owns the potential to contribute significantly to the cost-efficient integration of distributed and variable renewable energy sources. The lifetime of the floating platforms is expected to be much longer than 50 years. There is no reduction of the efficiency over time or any harmful environmental impact to expect. Anyhow, the energy density is relatively low and a lot of construction works are required. The challenges of the technology are the technical adaption system to the offshore conditions and a straight cost optimization mainly by adapting suitable construction methods and pump/turbine systems. Potentially Buoyant Energy could turn out to become the Break-Through-Technology in renewable offshore energy integration.
