Elestor's energy storage solution supplying clean and reliable power to drive industrial operations



Industrial scale partnership

Elestor has partnered with Royal Vopak, the world’s leading independent tank storage company, which specializes in chemicals and gas storage. The two have entered a Joint Development Agreement (JDA), under which they are jointly bringing the Elestor technology up to 10s of MW and 100s of MWh, and ultimately to industrial and commercial scale.

European projects

Elestor designed container-sized electricity storage systems under a number of regional, national and European Union programs. Elestor is currently completing these projects, which first started in 2018, as part of preparations for the commercial launch of the technology.

For one of the installations, which takes place under the GIFT (Geographical Islands Flexibility) project, an Elestor flow battery has been designed for a Norwegian island near the arctic circle.

Real-world pilots - finalized

Elestor successfully carried out a handful of field pilots, working under real-world conditions. The Elestor flow battery was connected to renewable energy sources and the grid, though with limited powers and capacities. Due to its working principle, there are no fundamental differences between a limited scale and a full-size system. The latter merely requires more of the same. Consequently, the field tests results were representative for large systems.

The primary purpose of these pilots was to demonstrate proper functioning under real world circumstances. Their secondary purpose was to investigate and obtain formal approval from the notified bodies to install Elestor’s innovative technology. The pilots were launched from November 2016. Each pilot ran for six to 12 months and they have all been finalized.

FleXtore II – finalized

The goal of this project was to arrange the basis for a scalable energy storage system based on the Hydrogen Bromine Flow Battery principles together with an external control and energy management system on a pilot location. The concept set out to enable more sustainable energy systems to be incorporated in the build environment, such as in houses or neighbourhoods.

This project received funding from the Netherlands Enterprise Agency RVO under the TKI Urban Energy program with grant number TEUE116904

Cleantech Energy Crossing (CEC) – finalized

The CEC project consisted of several work-packages. Elestor was active in work package (WP) 3, micro-grid storage. Other work packages were sustainable heating & cooling and batteries at homes. Withinthe micro-grid storage package, Elestor provided a Hydrogen Bromine Flow Battery to work together with decentralised energy sources, smart energy management systems and a charging infrastructure for electromobility. The project included a guarantee of energy origin. Within this environment the battery was tested and validated.

Project partners within WP3: • KiEMT • GWI Essen • (EMS company) • Dr. Ten • GPX Octrooi • Saxion Hogeschool • Zuyd Hogeschool • (Energy Management Company)

This project received funding from the INTERREG-program Deutschland-Nederland with grant number 153098 and with support from the European Union, het Nederlandse ministerie van Economische Zaken en Klimaat, provincie Gelderland, provincie Noord-Brabant, provincie Limburg en het “Ministerium für Wirtschaft, Innovation, Digitalisierung und Energie van Nordrhein-Westfalen”

Hydrous - finalized

The goal of this project is to develop, test and validate a decentralised storage system that consists of a hybrid arrangement between the Hydrogen Bromine Flow Battery and another type of energy storage, which on this occasion was a lithium-ion battery system. A proprietary energy management system optimises the hybrid cooperation between the two storage systems. The HBr battery targets 50kW/250kWh.

GIFT - finalized

GIFT is an innovative project that aims to decarbonise the energy mix of European islands. European islands have to abide by the laws of their respective countries, which push for a greener energy mix that complies with European and international agreements. GIFT aims to develop innovative systems that allow islands to integrate vast amount of renewables. The systems include virtual power systems, energy management systems, systems that better predict supply and demand, and systems that visualise those data through a GIS platform).

FlowCamp - finalized

FlowCamp is a research and training project from eight different countries, which will recruit 15 PhD students for the project. The project aims to improve materials for high-performance, low-cost next-generation redox-flow batteries. Renewable energy sources such as wind turbines require large-scale, stationary energy storage systems to balance out fluctuations in energy generation. Redox-flow batteries are considered to be one of the most promising solutions. The recruited fellows develop materials such as membranes, electrodes, electrolytes, catalysts, sealing materials, as well as macrohomogeneous models for three next generation RFBs (hydrogen-bromine, organic and zinc-air systems). They then upscale the new systems to prototype level, and validate them using the cutting-edge battery testing facilities available for the prestigious German-funded RedoxWind project at Fraunhofer ICT.

Project partners: • Amer-Sil SA • Bar Ilan University • CNRS-LEPMI • CNRS-LRP • MTA-TTK • JenaBatteries GmbH • Johnson Matthey • University of Chemistry and Technology Prague • University of Stuttgart Institute of Machine Components (IMA) • Zurich University of Applied Sciences (ZHAW), Institute of Computational Physics (ICP)

This project receives funding from the EU Research Executive Agency Marie Sklodowska-Curie Innovative Training Networks under grant number 765289
