BPT Simulator Benchmarked Towards Stargate Hydrogen Alkaline Electrolyser Stack

Stargate Hydrogen and Billington Process Technology AS (BPT) have in collaboration performed a benchmarking activity for green Hydrogen production.

BPT received information about the physical dimensions of the Stargate Hydrogen electrolyzer as well as a performance curve of the expected over potential as a function of the current. BPT introduced this information in the BPT-ECX simulator unit operation application and compared the results with the data received from Stargate. Based on the benchmarking results, the BPT-ECX is well fitted to be used in high-performance steady state and dynamic simulation models when accuracy is of importance.

"We are happy to collaborate with BPT, leveraging their simulation expertise and unique simulator add-ons to process simulators. Seeing that our revolutionary technology can be replicated digitally for Hydrogen systems but also as part of potentially bigger power to X systems like ammonia, methanol and e-fuel plants brings great hope for the future," expresses Rainer Küngas, CTO at Stargate.

“Our unique simulation technology that works seamlessly inside process simulators provides not just the opportunity to do basic design but also deliver high fidelity operator training simulators, perform control system checkout and deliver real-time digital twins based on actual vendor data.”, states Knut Erik Spilling, CEO at BPT. “We are very pleased with the collaboration with Stargate Hydrogen and excited about their efficient and competitive electrolysis systems.”

UniSim Design was used as the basis for the benchmarking, with BPT-SimApps seamlessly integrated with UniSim. This included a fit-for-purpose model of electrolysis (BPT-ECX). In addition, BPT-EXT Excel-add-in was used for easy comparison of simulation results.
