Join us to design, optimize, and scale hydrogen production processes

Are you passionate about technology for a greener world? You might be our new Senior Process Engineer.

Green hydrogen plays a central role in shaping a sustainable energy future. At Hystar, we believe the full potential of renewables can only be realized through large-scale energy storage and the use of hydrogen in heavy-duty transportation and industry.

Based on a new and unique patented PEM electrolyser concept, Hystar is developing the next-generation of PEM electrolyser to accelerate the deployment of large-scale green hydrogen production. Hystar is an innovative, fast growing, high-tech company, based at Høvik, just outside Oslo, Norway.
