We make the World’s
Most Effiicient Electrolysers
Founded in 2020 and headquartered in Høvik, Norway, our mission is to accelerate the transition to a sustainable energy system by making green hydrogen production more efficient, accessible and cost-competitive.
We develop and manufacture the world’s most efficient PEM electrolysers that use renewable electricity and water to produce hydrogen.
Our technology is built on more than a decade of research at SINTEF and has progressed from advanced materials science to real-world hydrogen production systems.
With over 40,000 hours of testing and operational experience in the field, we are now scaling globally.
Green hydrogen plays a critical role in decarbonising industries that are difficult to electrify directly, such as heavy industry, maritime transport, aviation fuels and fertiliser production.
As demand for clean energy solutions grows, efficient hydrogen production will become increasingly important to achieving global climate goals.
Our technology is designed to help project developers, industrial operators and energy companies produce hydrogen more efficiently and at a lower cost.
Currently, Hystar has an annual production
capacity of 100 MW in our existing facilities.
We are ramping the capacity with our
upcoming 4.5 GW automated factory.

At Hystar, we are dedicated to maintaining the highest standards of quality, safety and environmental responsibility across our operations. Our ISO 14001 and ISO 9001 certifications reflect our commitment to robust processes, continuous improvement and responsible business practices.
These internationally recognised standards provide our customers, partners and suppliers with confidence that we have the systems, governance and expertise in place to consistently deliver safe, reliable and high-quality products and services.
The stars run on hydrogen.
As the most abundant element in the universe, hydrogen powers the stars and has shaped our world since the beginning of time. At Hystar, we believe it can also help power a more sustainable future on Earth.
Our name reflects both the fundamental importance of hydrogen and our ambition to unlock its full potential through innovative electrolysis technology.
By making green hydrogen more efficient, scalable and accessible, we’re helping turn one of nature’s most abundant elements into a practical solution for the energy transition.
Hystar is a Norwegian cleantech company that develops and manufactures high-efficiency Proton Exchange Membrane (PEM) electrolysers for green hydrogen production.
We focus on accelerating the global transition to sustainable energy by improving the efficiency, safety, and cost of hydrogen production.
Hystar was founded in 2020 and is built on more than a decade of research and development in PEM electrolysis technology.
Hystar is headquartered in Høvik, Norway (outside Oslo).
Hystar’s mission is to make green hydrogen production more efficient, safe, accessible, and cost-competitive, enabling faster adoption of hydrogen as a key energy carrier in the global energy transition.
Hystar’s PEM electrolysers are designed for industries that require large-scale hydrogen production, such as:
Green hydrogen enables decarbonisation of sectors that are difficult to electrify directly. When produced using renewable electricity, hydrogen can replace fossil fuels in industrial processes and transport applications, reducing carbon emissions and supporting global net-zero targets.
Green hydrogen is expected to play a key role in decarbonising sectors that cannot be easily electrified. To enable this transition at scale, hydrogen production must become more efficient, safe, and cost-competitive.
Hystar’s technology is developed to support this shift by improving the performance and deployability of PEM electrolysers.
