About Hystar
Hystar is a forward-thinking company that specializes in the development and production of PEM (Proton Exchange Membrane) electrolysers, which are used to generate green hydrogen through water electrolysis. Green hydrogen is a clean energy source that can significantly reduce greenhouse gas emissions, making it a crucial component in the global transition to sustainable energy.
Hystar emerged as a spin-off from SINTEF, one of the largest independent research organizations, which underscores its strong foundation in research and innovation. The company operates in the green energy market, focusing on providing solutions that make the production of hydrogen from renewable electricity more efficient and cost-effective.
Hystar offers two main product lines of PEM electrolyser systems. These systems are designed with a modular approach, allowing for easy and flexible implementation across a broad range of applications. This flexibility makes Hystar's products suitable for various clients, including industries looking to reduce their carbon footprint, energy companies seeking sustainable alternatives, and governments aiming to meet environmental regulations.
The company's business model revolves around the development, manufacturing, and sale of these advanced electrolyser systems. Hystar generates revenue by selling these systems to clients who are looking to produce green hydrogen efficiently. Additionally, the company may offer maintenance and support services, ensuring that their clients can maximize the performance and longevity of their electrolysers.
Hystar is well-financed and growth-oriented, with a diverse and passionate team dedicated to advancing green technology. The company prides itself on its ethical approach, transparency, and commitment to delivering on its promises. By making green hydrogen production more affordable and accessible, Hystar is playing a pivotal role in the global effort to combat climate change.
