- Hydrogen Electrolyzer Control System
Honeywell Protonium™ Hydrogen electrolyzer control system
Welcome to the future of green hydrogen production. Honeywell proudly introduces the Honeywell Protonium Hydrogen Electrolyzer Control System (HECS), a specialized automation system designed to enhance the efficiency and lifespan of various electrolyzer technologies, including Alkaline Electrolyzers, Proton Exchange Membrane (PEM), and Anion Exchange Membrane (AEM). HECS is a cyber secure platform, enabling flexible communication through open communication support, this ensures improved performance, faster project delivery and lower risk, while integrating seamlessly with subsystems.

Enhanced Electrolyzer Performance and Comprehensive Monitoring
HECS excels in monitoring electrolyzer degradation and extending their lifespan. By continuously tracking key performance indicators (KPIs) such as efficiency and degradation, the system enables timely maintenance and reduces unplanned downtime. HECS enables optimization of PEM, Alkaline, and AEM electrolyzers by streamlining power allocation to electrolyzer stacks, tighter control and performance monitoring.
Electrolyzer Technology Agnostic Control
HECS is designed to be technology agnostic, providing robust control and monitoring support for Alkaline, Proton Exchange Membrane (PEM), and Anion Exchange Membrane (AEM) electrolyzers. This flexibility ensures that regardless of the electrolyzer technology in use, HECS can seamlessly integrate and optimize performance. By offering a unified control platform, HECS simplifies the management of diverse electrolyzer systems, enabling operators to achieve consistent and efficient hydrogen production across different technologies.
Comprehensive Automation Solutions
Honeywell offers comprehensive automation solutions for Green H2 and its derivatives, covering a wide range of use cases across project design, plant operations, and plant maintenance. Our solutions address pressing pain points and deliver CAPEX and OPEX savings.
Seamless Integration
Furthermore, HECS is a cyber-secure and IIOT-ready platform with flexible communication options, making it easy to integrate with various subsystem. This seamless integration reduces project integration time and enhances overall control reliability, ensuring that hydrogen production remains uninterrupted and cost-effective. This streamlined approach not only accelerates project timelines but also minimizes potential delays and disruptions.
