Battolyser integrates electricity storage and hydrogen production

Battolyser integrates electricity storage and hydrogen production

door C.N. Rood

The electricity grid is under great pressure. We face the challenge of providing affordable and clean energy that is always available. Smart solutions are needed to keep up with growing energy demand and to cope with increasing intermittency of renewable energy sources. These smart solutions must provide additional capacity and storage to keep the grid stable. The technology of Battolyser© is such a technology. Battolyser Systems is currently working on a multi MW system that can both store electricity and produce green hydrogen. Thanks to the storage capacity the system can have electricity even when the sun is not shining or the wind is not blowing; and thanks to the hydrogen it is also possible to decarbonize sectors that can’t easily electrify. We spoke with Rene de Milliano (project manager at Battolyser) about his company and the cooperation with CN Rood.

New possibilities for battery of Thomas Edison

The Battolyser system is based on the nickel-iron battery invented by Thomas Edison.
Rene de Milliano: “This nickel-iron battery had in the time of Thomas Edison the undesirable quirk of producing hydrogen once it reached a certain state of charge. In 2013 Prof. Dr. Fokko Mulder and his research group at Delft University of Technology saw the combined use as battery and electrolyser as an advantage. He and his team invented an efficient integrated battery and electrolyser - the Battolyser®. The Battolyser® can store and supply electricity as a battery. When fully charged it automatically starts splitting water into hydrogen and oxygen as an electrolyser with an efficiency of up to 90%. The system only uses Nickel and Iron electrodes, which are widely available at low cost, and have proven track record of 20+ years lifetime. The novel and ground breaking integration of these technologies remarkably improves performance, lowers cost and increases uptime. The system provides great flexibility, being able to follow the load profile of an renewable power source. It can turn power into hydrogen when electricity prices are low and deliver electricity back to the grid when electricity prices are high. The battery is used for short term storage of energy, the hydrogen is used for industry, transport or long term storage.”

From start-up to scale up

To further develop and commercialise the idea of TU Delft, Battolyser was established as a company in 2018. Rene de Milliano: "We started with the development of a first pilot with a 15kW/kWh capacity, to be deployed at the Magnum power plant in Eemshaven In 2020, Koolen Industries invested in the company to further commercialise the technology. After that the developments went fast. A new CEO was appointed and the organisation started to grow rapidly to already 40 people. We are now in the process of developing multiple commercial 1MW(h) systems which will be ready in 2023."

Looking for reliable and flexible partners

The technology of the Battolyser is still under development, so things can change quickly. Rene: "We are really looking for partners who want to go along with us. CN Rood is such a partner. They have a lot of knowledge and are also very flexible too. CN Rood supplies us with Delta Elektronika power supplies. We have been very satisfied with the quality of these power supplies for years. If we are in doubt about which power supply we need, we can count on advice of CN Rood, but it also happens that we try different types to see which one best meets our needs.”

Degelijk.  Betrouwbaar. Kennispartner.

De CN Rood groep is koploper in kennis en oplossingen op het gebied van test- en meetapparatuur. We onderscheiden ons met een persoonlijke en klantgerichte aanpak. Onze klanten zoeken vaak niet een product, maar een oplossing en wij hebben allemaal de gedrevenheid om mee te werken aan die oplossing. Wat wij het liefste doen: continu bezig zijn met de nieuwste ontwikkelingen op het gebied van test- en meetapparatuur. Nu, en in de toekomst. Want daar ligt nu eenmaal onze passie: het precies willen weten. Zo kunnen we onze klanten optimaal verder helpen.

Wij denken mee, adviseren en begeleiden onze klanten in het maken van de juiste keuze in hun test- en meetapparatuur. Mensen in verschillende sectoren vertrouwen op onze expertise en ons advies. We werken voor overheid, wetenschap, onderwijs, lucht- en ruimtevaart- en auto-industrie in Noord-Europa en de Benelux. Daaronder bevinden zich vele prestigieuze en vooraanstaande organisaties. Vanuit locaties in Zweden, Nederland en België werken meer dan zestig toegewijde professionals aan oplossingen variërend van communicatie-testapparatuur en algemene test- en meetinstrumenten tot apparatuur voor data-acquisitie, logistieke automatisering, aangevuld met consultancy, training en turnkeyoplossingen.

We hebben een historie die teruggaat tot 1938. Onze oprichter, Cornelis Nicolaas Rood, was destijds een pionier in moderne elektronica. Onze mensen bevinden zich ook anno nu graag in de frontlinie van technologische ontwikkelingen. Op onze eigen manier leveren we zo een bijdrage aan belangrijke maatschappelijke vraagstukken. Bijvoorbeeld in energietransitie, quantum computing, medische technologie, de zelfrijdende auto, de auto op zonne-energie, de energie transitie en alle andere deeptech die bijdraagt aan de schonere en betere wereld van morgen.

Daarom letten we ook op onze eigen impact op het milieu en klimaat. Aangezien wij vooral een adviserende functie hebben is onze eigen milieu-footprint gering. Vanzelfsprekend zien we wel toe op een zo duurzaam mogelijke productie van de apparatuur die wij verkopen en zorgen we voor een maatschappelijk verantwoorde bedrijfsvoering. Al onze producten kopen we uitsluitend in bij gecertificeerde fabrikanten die werken met herleidbare en verantwoorde grondstoffen. Gebruikte apparatuur wordt kosteloos opgehaald en gerecycled.

Het zijn maar een paar voorbeelden om duidelijk te maken dat we hechten aan een langetermijnvisie op de wereld om ons heen. Want juist met een geschiedenis van meer dan tachtig jaar kun je goed vooruitkijken. Daarom blijven we ook vooroplopen. Onze brede en diepe technische kennis van test- en meetapparatuur, in combinatie met onze persoonlijke connectie met onze klanten, maken ons uniek in de markt. De CN Rood groep is uw degelijke en betrouwbare kennispartner voor test- en meetapparatuur!
