Kampen, May 25, 2018 – Elestor operates first HBr flow battery at commercial operation.

KAMPEN – With the official activation of Elestor’s hydrogen bromide flow battery, ITMGroup has taken its first steps to expand its smart grid in Kampen with a sustainable and cost-effective electricity storage technology. It enables the machine builder to take an important step in fully self-generating the electricity the company needs.

The installation at ITMGroup is intended to demonstrate on a limited scale, that the HBr flow battery, developed in-house by Elestor, is cost-effective for companies. The technology can thus contribute to reducing CO2 emissions and achieving climate targets.

The installation at ITMGroup is the first commercial placement that Elestor makes. From 2019 onwards, the storage capacity at ITMGroup will be expanded. This allows ITMGroup to be self-sufficient in energy needs, even when its own smart grid does not generate sufficient electricity, for a long period of time.

An HBr flow battery makes energy storage more economical and environmentally friendly, compared to existing technologies such as lithium-ion batteries. The economic yield of, for example, solar panels and windmills, is much higher due to the storage capacity. This makes it more attractive for more companies to invest in sustainable energy generation and storage.

Because ITMGroup has a smart grid with, among other things, 1,700 solar panels, two heat pumps and a wood chip boiler, the Kamper company offers Elestor perfect conditions for applying its innovative energy storage technology. Hester Kuypers, board member of ITMGroup: “Worldwide we are faced with an enormous task when it comes to the energy transition. By only installing more solar panels and windmills, we will not make the switch to sustainable energy. Making electricity storage affordable is therefore a necessity and Elestor’s technology brings it within reach. We think, it is important that we, as an international company, can demonstrate that it works!”

Guido Dalessi, director of Elestor: “We are very pleased with the cooperation of ITMGroup. Everyone is willing to buy the fiftieth installation of a proven technique; but the first sales are often much more difficult. ITMGroup fulfils a pioneering role in scaling up our technology. In addition, ITMGroup has plenty of technical experts who want to share their knowledge with us. They think along with us to further optimize this innovative way of storing electricity. ”

As a family business, ITMGroup strives to minimize its ecological footprint. In addition to investing in sustainable energy, it supply’s electric bikes and cars for daily traffic of employees, and it is keeping bees on the company premises. Kuypers: “As a global player, we want all our sites to operate as energy-neutral as possible, in ten different countries and we are happy to support our approximately 1,200 employees in realizing sustainable solutions. In this way we not only leave a beautiful company to future generations, but hopefully also a world as beautiful as possible.”

Based on this vision, the collaboration with Elestor has come about smoothly. Since 2014, the company has been working on the further development of cost-effective storage for electricity.

IPKW - Poortgebouw

Elestor moves to ‘Industry Park Kleefse Waard’ (IPKW)

In the first week of January 2018, Elestor will move to its new premises on ‘Industry Park Kleefse Waard’ (IPKW) in the city of Arnhem. “The direct motivation for this move was our growing need for more laboratory space”, says Guido Dalessi, Elestor’s CEO. “The choice for IPKW was almost too obvious, and then I am not only referring to the building itself, but also to the (personal) support of IPKW and the proactive attitude in thinking along with us in order to create the required conditions for a longer period of time.”







Battery cluster 

Kevin Rijke, Managing Director of IPKW: “Already during the past years we noted an increase of activities around storage. This initially took off with several startups, who have now entered the scale up phase, to eventually become mature companies. We are ready to invest in the present cluster of companies, because we believe that storage, together with hydrogen technology, is one of the spearheads putting Arnhem clearly on the map. These technologies offer solutions for the most important energy issue we will have to deal with in the near future.”

IPKW already has a lot of in-house knowledge and works closely together with Han University of Applied Sciences (HAN), amongst others in the field of clean mobility. As such the Clean Mobility Center had been established with a group of companies and educational institutes. Rijke: “It is a logical next step to create a large project around the subject of storage, and this is why we interconnect parties as well as physically bring these parties together on our industry park. Companies located all over Arnhem and on the industry park are very enthusiastic about forming such cluster, with a central hub under one roof. A party like Elestor, already located in Arnhem and who we consider the flagship in its field, specifically chose for this cluster at IPKW.”

Dalessi: “The concentration of parties, all active in storage and/or hydrogen, creates a clear synergistic effect on technology developments and places the ‘storage technology flag’ on IPKW in Arnhem. With our move, our mission to contribute to the energy transition will be realized by building large scale hydrogen flow batteries on IPKW, as the first in Europe.”

Mutual goal
The cluster does not limit itself to the boundaries of IPKW and several connections exist with companies like DNV GL and DEKRA. These kinds of cooperation are necessary, as Rijke emphasizes. “Different parties work on different technologies, but the essence is the same for all: How do we accomplish sustainable and efficient energy storage ? With this mutual goal, we also hope that test and certification companies will join us in Arnhem. Only together we can make huge progress and develop this cluster into an Energy Storage Expertise Center.”

International research network “FlowCamp” aims to revolutionize energy storage by developing the next generation of redox-flow batteries

Partners in the FlowCamp network at the project kick-off meeting in September 2017: Fraunhofer ICT (DE), Elestor BV (NL), Bar Ilan University (IL), Hungarian Academy of Science (HU), CNRS (FR), JenaBatteries GmbH (DE), Amer-Sil S.A. (LU), Zürcher Hochschule für Angewandte Wissenschaft (CH), University of Chemistry and Technology, Prague (CZ), University of Stuttgart (DE)
Pfinztal, 22.09.2017 (PresseBox) – Renewable energy sources like wind turbines and photovoltaics need large-scale energy storage systems to balance out fluctuations in energy generation. One of the most promising solutions is redox-flow batteries. These systems store energy electrochemically, within liquid electrolytes that can be kept in tanks until the energy is required.

Redox-flow batteries are efficient (>75%), safe, and have a longer service life than conventional batteries such as lithium ion. Different combinations of electrolytes offer a range of advantages in terms of higher power or capacity and environmental compatibility. However, to fully exploit the possibilities, research is needed into materials (membranes, electrodes, electrolytes, catalysts and sealing materials) for the new battery systems.

Coordinated by the Fraunhofer Institute for Chemical Technology, and funded by the European Union’s Marie-Sklodowska-Curie programme, in the research network “FlowCamp” (MSCA-ITN-2017- 765289), 15 PhD students will develop materials for three next-generation redox-flow battery systems: hydrogen-bromine, aqueous organic and zinc-air flow battery systems. The team will also carry out simulation and modelling to guide the development and increase power output. Prototypes developed in the project will be tested using the cutting-edge facilities of the German-funded (19 million €) RedoxWind campus at Fraunhofer ICT.

Besides advancing the development of the new systems, FlowCamp will fulfil another important role: the combination of multiple disciplines (including electrochemistry, material science and engineering / system design) is essential to develop optimal battery systems, but at present few researchers have the necessary overview. The 15 PhD students in FlowCamp, who will start work in mid-2018, will gain a unique skill set through theoretical and practical work covering every aspect of system development, as well as training in transferable skills such as project management, which will prepare them for their future careers in the expanding field of energy storage.

The network offers the chance for outstanding graduates with the appropriate qualifications to participate in an international project with industrial and academic partners from Germany, the Netherlands, Israel, Hungary, France, Luxembourg, Switzerland and the Czech Republic. For more information about the project and the open PhD positions, please contact the project coordinators at the Fraunhofer Institute for Chemical Technology (ICT), Germany.

The jury was formed by Jonas Deitschun MSc (Fraunhofer IFAM), Dr. Fanny Barde (Toyota Motor Europe), and Dr. Giuseppe Antonio Elia (TU Berlin), commenting: “This company is betting on a utility-scale stationary storage system that does not require a hydrogen compressor, thereby enabling lower LCoS than its competition.





Official start of Elestor’s HBr technology pilot at Witteveen+Bos, Deventer

On Monday, November 7, 2016, the first pilot of Elestor’s Hydrogen Bromine Flow Battery (HBFB), operating under real life conditions has been officially started in Deventer, the Netherlands. The consortium, consisting of Elestor, Witteveen+Bos, Energy research Centre of the Netherlands (ECN) and the HAN University of Applied Sciences (HAN), investigates with this pilot the optimal way of applying this storage technology on a large scale. The pilot is a first in Europa.

Witteveen+Bos facilitates the pilot: The storage system is installed at one of their office buildings in Deventer and is connected to a set of innovative solar panels. These panels have been developed by ECN, based on their Back Contact (BC)-technology. In contrary to conventional solar panels, these BC modules are only interconnected on the rear side, resulting in less shadow effects, a more efficient use of active area, lower production costs (higher yields) and a much more aesthetic design. HAN University has taken care of system integration and power electronics subjects of the project.
Furthermore, Witteveen+Bos, being a specialist in this field, has taken the lead in the definition of safety procedures and in obtaining formal approvals from the Dutch authorities.

During the ceremony on November 7th, Karin Sluis, Managing Director of Witteveen+Bos, emphasized on the importance of the joined effort as made by all consortium partners: “In our projects, we apply 6 sustainable design principles, based on the by the United Nations defined ‘Sustainable Development Targets’ “says Karin Sluis. “This Flow Battery pilot is a beautiful example of how we can jointly accomplish these targets”. After an introduction of the working principles and features of the Flow Battery by Wiebrand Kout, CTO of Elestor, and a lecture about the innovative Back Contact technology by Nico Dekker, Senior Advisor at ECN, alderman Frits Rorink of the city of Deventer underlined the importance of this pilot for the city.
At the end of the presentations, the pilot was started symbolically with a joint push on the start button, illuminated by an nice firework act.

Elestor enters participation agreement with Enfuro Ventures and KIC InnoEnergy

Just before the end of 2015, the closing of the Shareholder and Participation Agreement with Enfuro Ventures and KIC InnoEnergy took place. The agreement forms a very important milestone in the development of Elestor BV, and covers the scale-up of the company during the next years.

In the words of Wiebrand Kout, founder and CTO of Elestor BV: “We were delighted to experience such a great deal of interest from the industry and financial markets. Our storage technology and business proposition received a lot of attention, from several, also international, parties. It therefore turned out that identifying funding opportunities was not our most challenging task. Instead, finding investors, not only capable of funding but also sharing and supporting Elestor’s philosophy and business strategy, indeed was.

Apart from providing the financial means to develop Elestor, we considered of equal importance that our investors themselves have a track-record as entrepreneurs, and as such act as our sparring partners and sounding board. In this respect, both Enfuro Ventures and KIC InnoEnergy are the perfect partners for realizing the anticipated growth of Elestor BV”.

In the same financial closing, Guido Dalessi, CEO of Elestor BV, joined the group of investors.

KIC InnoEnergy’s mission is to build a sustainable long-lasting operational framework amongst the three actors of the knowledge triangle in the energy sector: Industry, Research and higher education, and ensure that this integration of the three is more efficient and has a higher impact on innovation (talent, technology, companies) than the three standing alone.

Elestor BV forms DOAblE Consortium

Elestor BV forms DOAblE Consortium to investigate maximum economic value of electrochemical storage

‘Decentralized Storage of Alternative Energy’

(Dutch : ‘Decentrale Opslag van Alternatieve Energie – DOAblE)’

The ability to store electrical energy has become a precondition to maximize the generation of renewable energy. The technology to generate the various forms of renewable energy is widely available, however, the economics for integrating storage technology in order to maximize its added value is a very complex topic. The DOAblE project offers a unique opportunity to combine the knowledge and experience of top-level industry partners and knowledge institutes to create a scientifically underpinned picture of the highest potential options for electrochemical storage of electricity.

Early 2015, Elestor formed a consortium referred to by the name ‘DOAblE’ (a creative acronym for the Dutch translation of ‘Decentralized Storage of Alternative Energy’). The consortium partners Elestor, DNV GL, Alliander and TU/e (Group: Electrical Energy Systems), have entered a cooperation, which is funded by RVO under the ‘TKI System Integration’ program, for a period of 2.5 years. The program started in March 2015.

The 4 partners all hold an own unique knowledge position in the Netherlands, having extensive experience with model-based analysis of the electricity supply, with electrochemical storage, as well as with knowledge of the interfaces between storage and electricity networks.

The main challenge of the consortium is to investigate the value creation by integrating electrochemical electricity storage in the electrical energy systems. In other words, the question to be answered is where exactly in the value chain, electrochemical storage will create maximum economic value, and how this can physically be integrated into the value chain.

The individual knowledge and expertise of each consortium partner have shown to be highly complementary, though in overall fragmented.

The resulting reports offer guidelines for developers, legislators, investors and users, who are or will be in any form involved in electricity storage technology. These guidelines will describe how to optimize the application of electrochemical storage systems and how to realize a profitable business case by combining revenue streams.
