INNOMOTICS LARGE DRIVES AND MOTORS LIMITED

ENGINEERED POWER SUPPLY SOLUTION FOR GREEN HYDROGEN RESEARCH

ELECTRIC MOTORS AND LARGE drive systems specialist Innomotics has received an order from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, Colorado, to provide a rectifier power supply system for an electrolyser testing facility for green hydrogen electrolysers.

Hydrogen is considered a key technology driver for the future when it comes to reducing CO2 emissions and transitioning to renewable energy. Therefore, the demand for technologies like the Innomotics PR150, that help produce hydrogen safely and cost effectively, is expected to increase.

With a 60-year history of engineering, installing and supporting high power rectifier-based solutions for a wide range of industrial applications, such as electrowinning, Innomotics tailored the design of the PR150 specifically to green hydrogen production. With its high efficiency and scalability, the product is suitable for both low-voltage and medium voltage applications and is specifically designed to power hydrogen electrolysers with a power range of 5 to 16 MW.

As part of the order, three Innomotics PR150 units will be produced in Germany and delivered to the U.S. for installation in a 40ft packaged control room together with the balance of the rectifier control and circuit protection equipment. The complete system will be installed at NREL’s Flatirons campus with a planned start-up in Q2 2026.
