An electrolysis stack is the heart of a system for hydrogen production. The electrolysis stack, named Stellar 100, is manufactured in Europe and has a production capacity of up to 100 Nm3/h, which means that every hour it produces enough energy to power a car for 1000 km.
Its patented design was developed by Stargate in cooperation with leading European suppliers and tested by ZSW, a renowned German research institute.
Thomas Ottitsch, Manager of the Electrolysis test field (ElyLab) at ZSW said: "It was a pleasure working together with Stargate Hydrogen's team to test their stack technology at our test facility in Stuttgart (Germany). Our independence and scientific approach ensures that the test results compare to other tests with high confidence. We measured the average cell voltage in the stack to be lower than 1.85 V (at 0.5 A/cm², 15 barg, 70°C), corresponding to a stack-level efficiency of 80% (HHV)."
The new product is available to the market with the first two stacks earmarked for a 1 MW project in Estonia, followed by a 1 MW delivery to a project in Germany.
