Optimize your electrolyzer power supply through a powerful and scalable power rectifier UNIREC H2.

We are now at the start of the age of hydrogen. Produced using renewable resources,

this versatile element could well prove to be the key to meeting the most important

challenge of our time – the decarbonization of our economy.

ABB is already today deploying technology and solutions to support the new hydrogen

value chain as we transition to a cleaner energy future.

Benefiting for more than 100 years of experience in the development of

DC rectifiers for power generation industry with thousands of equipment in operation worldwide,

ABB has designed a powerful power rectifier UNIREC H2.

Based on a proven full-wave thyristor converter and ABB latest control technology,

UNIREC H2 supply the necessary electric current to dissociate water molecule and produce hydrogen.

Designed for projects with high requirements in terms of performances and capacities,

ABB UNIREC H2 is based on high-end control technologies and advanced regulation and protection

functions.
