Een Nederlands bedrijf uit Zwolle levert de koppeling tussen de grootste fabriek voor groene waterstofproductie in Scandinavië en de duurzame energiebron. Hiermee levert het een belangrijke bijdrage aan de uitbreiding van de groene waterstofeconomie in Europa.

VONK ontwerpt en levert innovatieve elektrotechnische installaties, waaronder ook oplossingen voor conversiesystemen voor electrolysers. Electrolysers worden gebruikt om water met behulp van elektriciteit te splitsen in waterstof en zuurstof. Wanneer dit met duurzame energie gebeurt, zoals zon, wind of waterkracht, dan wordt gesproken over groene waterstof.

Om een electrolyser aan te sluiten op het elektriciteitsnet is een conversiesysteem nodig dat de hoogspanning van het wisselstroomnet omzet in gelijkspanning die geschikt is voor de electrolyser. Daarbij geldt dat de karakteristieken voor elke electrolyser verschillend zijn en dat beheerders van elektriciteitsnetten (zoals TenneT) andere eisen stellen aan het elektrische gedrag van het conversiesysteem. Dit zorgt ervoor dat specifieke kennis vereist is om dergelijke oplossingen op een grote schaal te maken. Wereldwijd is slechts een beperkt aantal bedrijven hiertoe in staat en VONK is er hier één van.

Het zogenaamde P2X project waarvoor VONK het elektrische conversiesysteem levert, wordt gerealiseerd in Harjavalta in Finland. De elektriciteit voor dit project wordt gegenereerd door een waterkrachtcentrale. VONK werkt voor het P2X project samen met het Duitse Sunfire, dat de electrolyser levert. Met een grootte van 20 megawatt is dit project even groot als de grootste electrolyser die momenteel in Europa in bedrijf is. De eindklant P2X Solutions kondigt aan in de komende tien jaar nog 1000 megawatt extra aan capaciteit te bouwen.

Ook bij andere bedrijven wordt de komende jaren een enorme groei verwacht in de elektrolyse capaciteit. Daarmee wordt ook de impact van de electrolysers op het elektriciteitsnet steeds groter, waarmee de expertise van bedrijven als VONK steeds belangrijker wordt om dergelijke projecten te kunnen realiseren. VONK verwacht daarom de komende jaren forse groei.

Vonk and DutchVentus have recently signed an agreement to cooperate as partners for the design and delivery of Hybrid Power Systems (HPS) in which the wind turbines of DutchVentus are integrated in the Hybrid Power System of Vonk. Such systems are smart combinations of renewable power generation based on solar and/or wind, energy storage and energy distribution, all controlled by a smart Power Management System.

These green power solutions have already been successfully applied offshore, on O&G platforms in operation or lighthouse mode, and onshore, to provide different power consumers, equipment and industrial processes with green energy, if needed backed up by an emergency diesel generator.

The addition of the 10kW venturi type wind turbines of DutchVentus to Vonk’s Hybrid Power Systems brings real added value and will help decarbonize your business even further.

On 24 March 2022 VONK received an award from Orano during their Supplier Award Ceremony in Paris, in the category ‘Competitiveness’.

Merijn van Mourik (MD) and @Thomas Andre (Site Team Lead) received the award from Mr. Edouard Blondel (Supply Chain Director) and Mr. Jacques PEYTHIEU (Business Director of the chemical enrichment unit).

Orano were especially impressed by VONK’s performance in the Energy Saving project. By re-engineering the electrical power drives, the Energy Saving Project will allow for a large reduction in power consumption in Orano’s uranium enrichment plants.

The power consumption savings are expected to be the equivalent of the yearly average energy usage of about 2,500 households.

As VONK we feel proud and appreciated and will continue supporting Orano in making their production more efficient and even greener.

As VONK we are proud to have been granted an order from NOBIAN Industrial Chemicals for the engineering, fabrication, outfitting and testing of five prefabricated substations for the electricity supply for five  new salt production wells in Haaksbergen, the Netherlands.

Before delivery to the salt wellhead locations in Haaksbergen, the pre-fabricated substations will be 100% functionally tested in order to reduce the commissioning period in the field as much as possible.

The five prefabricated substations will be delivered in four  batches in the third quarter of 2022.

The prefabricated substations will contain the following equipment:

  1. 10 kV Ring Main Unit/Switchgear;
  2. 10/0.4 kV transformer;
  3. Low voltage switchgear;
  4. UPS system;
  5. Airco unit;
  6. Distribution Boards.

In 2023 NOBIAN Industrial Chemicals will start salt production in Haaksbergen. Due to the thick salt layer in this area  it is possible to guarantee the long term  salt production in a safe manner, with a limited number of new wells to be drilled. In the years after the area will be further developed following a “step-by-step” approach, until 2055.

From the salt wellhead locations the “brine” (salt water) will be transported through a pump station to a treatment plant in the town of Hengelo.

More than a decade ago we supplied our advanced medium frequency drive systems to our French customer, who is active in uranium enrichment. Since then we have been doing the level 1-4 maintenance on these drive systems as well. Because the electronics in the drive systems are getting older now, we have recently set up a more pro-active approach for these drives. Within this pro-active Risk Based Asset Management approach, we have developed the so-called VONK Life Cycle Management (LCM) programme, for which we were recently granted a six years contract by our French customer.

The VONK LCM programme comprises of the following main components, each with their specific added value for the customer:

Obsolescence management – by continuously monitoring the potential obsolescence, the customer will know at an early stage which components will become obsolete and whether they can be replaced by an alternative or need to be re-designed,

Knowledge retainment – we will make sure that the necessary knowledge will stay available at the right level and within sufficient resources,

Keeping Technical Product Documentation (TPD) up-to-date,

Maintenance of customer-specific electronics test facilities,

Managing all security sensitive data and documentation storage, including security screening of employees.

Are you interested in the possibilities of Life Cycle Management for your power and electronics related installed base as well, please contact us to find out together how we can create value for you.
