Hystar offers two product lines of PEM electrolyser systems: Vega™ and Mira™. For larger systems, we have Orion - a constellation of either Vega or Mira... or a combination of the two!
Vega is Hystar’s efficiency queen and is the obvious choice for systems where the cost of energy constitutes a large share of the total costs, such as in large industrial applications. Hystar’s innovative and patented designs provide a step-change in terms of electrolyser stack performance, opening new PEM electrolysis opportunities. Compared to conventional PEM electrolysers, Vega has a 10% lower energy usage, yet still provides the same broad flexibility and partial load opportunities as other PEM electrolysers.
Mira is designed to provide optimized performance for systems powered by intermittent energy sources, such as wind, solar (PV), or unregulated hydro. Mira is also ideal for applications with a variable hydrogen production rate, or where the demand for hydrogen is variable. Mira provides broad flexibility in terms of production rates and can reduce capital investment costs compared to conventional PEM electrolysers.
Orion is our large plant, modular solution, and will likely be the optimal product choice for you if you are looking to build a large hydrogen factory. Orion is a constellation of either Vega or Mira stacks (or a combination of the two), packed together in a very space-efficient manner, enabling a very small plant footprint. Orion can therefore be designed to provide an optimized performance for either high efficiency or high production rates.
There are large differences in how hydrogen will be used, produced, and operated. Thus, we offer different product categories to meet the specific needs of your particular application.
