A Series electrolysers are based on our proven 2.2 MW modular A485 design. With a power consumption at the stack of 4.5 kWh/Nm3 of hydrogen gas produced, they are the world’s most energy efficient electrolyser. Utilizing this core technology, customers are able to build complete hydrogen plants at scale, reaching into the hundreds of MW and even the GW levels.
Features
- Unprecedented Efficiency: At the stack level, the A Series boasts a remarkable cell stack power consumption as low as 4.5 kWh/Nm³ and sets a new standard for energy efficiency in hydrogen production.
- Scalability Redefined: A485 electrolyser stacks can be combined to meet any production capacity requirements.
- Unmatched Safety Standards: A485 stacks operating at atmospheric pressureand ensure an exceptionally safe environment.
- Complete Solution Package: Nel provides a process and safety control system for the atmospheric part of your hydrogen generation system.
