Alkaline electrolyzers. Another step forward in global decarbonization.
Our goal is to unlock the potential of remote sites with exceptional renewable energy capacity factors for the production of green hydrogen, a sustainable energy vector obtained from the electrolysis of water, using renewable energy, like wind.
After production, green hydrogen can be stored and transported to be used to decarbonize hard-to-abate sectors, such as aviation, maritime or steel industries, driving the green energy transition forward. The demand for hydrogen is projected to experience a remarkable surge of approximately 700 percent in the next three decades. The electrolyzer is a key component in the production of green hydrogen.
To achieve the target of net zero by 2050, the majority of energy will need to come from clean sources.
Hydrogen is expected to play a major role in the energy transition. As an energy vector, it can be used to produce other molecules, such as ammonia or e-fuels, thereby contributing to the decarbonization of hard-to-abate sectors, such as aviation and maritime transport, or fertilizer production.
MW‑scale electrolyzer, delivering 50 kg of hydrogen per hour at a nominal power of 2.5 MW.
This new pressurized alkaline electrolyzer sets a new benchmark for efficient, scalable, and reliable green hydrogen production - optimized for variable renewable energy and advancing global decarbonization.
Nordex electrolyzers for green energy production are specifically designed to work under fluctuating conditions of renewable power generation.
Our pressurized alkaline technology is engineered to deliver exceptional operational flexibility, allowing seamless integration with variable energy inputs without sacrificing efficiency or equipment longevity. Nordex electrolyzers are built for robustness and reliability, simplifying daily operations while optimizing your upfront investment. Designed with maintenance in mind, our systems minimize service requirements and operating costs, ensuring safe, cost-effective performance throughout the entire lifecycle.

High flexibility
Specifically designed to work under the fluctuating conditions of renewable power generation. Our deep understanding of this variability enables us to support our customers in making informed decisions about their energy generation strategies. Our products operate with variable partial load, overload, load range and ON/OFF conditions, while taking into account system response time. - Low energy consumption
The mechanical design of the stack provides high voltage efficiency and the basis of our product strategy.
Nordex Electrolyzers S.L. aims to reduce energy consumption, at stack level, to below 50 kWh/kg. Fluid-dynamic optimization, efficient cell design limiting shunt currents and electrodes especially suited for work with renewable energies allow these objectives to be achieved. - Reduced size
Even though our hydrogen production systems have been designed for environments in which space is not constrained, we aim to reduce the footprint of our alkaline electrolyzers by half, compared to conventional electrolysis systems that operate at 250-350 mA/cm2, by operating the system at 600 mA/cm2 density. -
Long lifetime
Typical degradation rates of 1-3 µV/h provide Nordex alkaline electrolyzers with a service life of up to 80,000 hours in the stack and 20 years in the balance of plant. Our engineers have carefully selected the materials and optimized the design of the stack to maximize its lifetime under renewable energy conditions. One of the key advantages of Nordex Electrolyzer technology is the long durability of the electrodes.
5000 kW and 10000 kW modules will be available for delivery starting in Q1 2027.
