Competitive Electrolyzer Converters

Green hydrogen produced with clean electricity is seen as one of the critical enablers for the global transition to sustainable energy and net-zero emissions economies. Consequently, a significant increase in the utilization of electrolysis technologies is predicted.

Recently, several electrolyser projects in many countries have been announced and huge growth in the number of projects is expected. Additionally, the size of the projects is expected to grow significantly. With the increased size of the electrolysers, the power electronics used in them have become one of the key elements for affordable clean hydrogen production. With large plant sizes in the range of 100 MVA and up, the interconnection of the electrical power converter with the power grid becomes essential. Furthermore, power electronics enabling high efficiency and low capital cost (lower CAPEX) are required.

The main objectives of this project are:
- Power converters for electrolysers with improved efficiency, low cost, and provisions for grid services
- Power converters, which together with electrolyser stacks can provide improved system efficiency (lower OPEX)
- Targeting large scale converters of 5 MW+
- Using both a physical build and virtual concept to test the developed solutions
