According to the company, the further development aims to reduce the complexity of hydrogen projects and enable repeatable implementation on an industrial scale. As project size increases, issues such as integration, installation, commissioning, and maintainability become more significant, according to Vonk.
Low harmonic distortion and power factor over 0.99
Neya 3.0 is designed for a maximum DC voltage of 1,000 VDC and a maximum DC current of around 15 kA. According to the manufacturer, the output per unit reaches up to 7 MW. The platform uses an Active Front End architecture and aims to achieve a power factor of more than 0.99 and a total harmonic distortion in current (THDi) of less than 2 percent. With this, Vonk intends to ensure the grid compliance of the systems.
The systems are designed for both indoor and outdoor use and cover protection classes from IP20 to IP65. They are rated for corrosion exposure according to categories C4 to C5M. Communication is via Profinet, and functional safety reaches levels SIL2 and SIL3.
References from Finland and Belgium
According to the company, the development of Neya 3.0 incorporated experiences from operational hydrogen projects in Finland and Belgium. Insights from engineering, logistics, commissioning, and operation were directly integrated into the architecture of the new generation. Vonk cites, among others, a 20 MW project in Harjavalta, Finland, which is already operational, and a 25 MW project in Zeebrugge, Belgium, which has been delivered, as references.
According to the manufacturer, the development goals include a standardized architecture, defined interfaces, simplified integration, faster installation, and improved maintainability. This is intended to increase repeatability in project implementation.
Vonk claims to have already delivered power conversion solutions for projects with electrolyser manufacturers such as Sunfire, John Cockerill, Nel, and Plug Power, as well as with Fest. The company also points to experience from the oil and gas industry and uranium enrichment.
Vonk is based in Zwolle, Netherlands, and develops power conversion solutions for industrial applications. With the Neya platform, the company addresses the integration of power conversion systems for large-scale electrolysis projects.
