We make

what’s in our name?

At Hystar, we believe that the future of green hydrogen is “written in the stars.” This is because the stars themselves – and in fact, nearly the entire universe, if you add up all the atoms – are made up of mostly hydrogen

products

Hystar's market-leading PEM stacks have the world's highest efficiency and are made in Høvik, Norway. We sell Vega - containerized 5 MW solutions, Orion - large-scale 20 MW clusters and Eos - 0.55 MW stacks.

Our mission is to significantly reduce the cost of green hydrogen
