[ cover story ] for green hydrogen , Hystar is fully aware that quenching the thirst for hydrogen of industrial customers will require an electrolyser solution that can be easily scalable from 20 MW to 1 GW and beyond . Named Orion and described as a constellation of either Vega or Mira stacks ( or a combination of the two ), Hystar ’ s modular electrolyser concept provides exactly that .
“ Unlike containerised electrolysers , which are standardised , ‘ plug-and-play ’ products , so to speak , large-scale plants typically require customised solutions ,” explains Jan . “ To avoid having to design every plant from scratch , we are busy developing a scalable electrolyser concept based on modules that can be multiplied to create a large green hydrogen plant of virtually any capacity . In an ideal world , we would be able to build large-scale electrolysers just like any Lego structure , so adding a given number of standardised building blocks , or modules , to reach the desired plant capacity and specifications . This is the idea behind the Orion concept : building large facilities using multiple stack modules and just one balance of plant . By achieving this , we will be able to reduce production costs , improve the quality of the product and shorten lead times because there will be no need to re-engineer again and again .”
Sustainability
Along with efficiency and scalability , sustainability is at the heart of Hystar ’ s endeavours , playing a key role not only in supplier management , but also process development . Committed to a circular economy and aware of the scarcity of catalytic materials used in PEM electrolysers , the company is determined to facilitate their reuse in every
What ’ s in the name and logo ?
The company name – Hystar – is inspired by the abundance of hydrogen in the universe . With the lightest of all elements being the main constituent of stars , the future of green hydrogen is seen by Hystar as being written in the stars . The shape of the logo is inspired by a hydrogen density plot that represents how the electron of a hydrogen atom moves in orbit , capturing the dynamic and vibrant character of Hystar . Additionally , the logo has strong references to water , as the thin lines add a dynamic feeling , giving associations to water ripples , and each ‘ petal ’ ( orbital ) resembles the shape of a water droplet . The logo can also be seen as an ‘ H ’ for Hystar , or even as a clover leaf , representing sustainability .

possible way they can . Jan elaborates : “ Everything we do is done with sustainability in mind . As part of the Autostack project , for example , we are looking at how to design and build our stack in such a way that after the end of the product ’ s lifetime , all its recyclable parts can be recycled as easily as possible . In addition , we are exploring different options to reacquire end-of-life products from our customers as well as engaging with industry partners about the best recycling routes .”
“ Reaching for the stars , we believe in a bright future – for Hystar and our planet ,” concludes Jan .
