What Is Green Hydrogen and Why Is It Key to Siemens Energy’s Investment?
Green hydrogen is hydrogen produced through water electrolysis powered exclusively by renewable electricity, resulting in zero carbon emissions. This sustainable fuel acts as an energy carrier and storage medium, enabling long-duration balancing of solar and wind power while displacing fossil‐based hydrogen in industrial processes. For Siemens Energy, green hydrogen underpins efforts to decarbonize hard-to-abate sectors, integrate renewable generation, and drive profitable growth through advanced electrolyzer systems like Silyzer and Elyzer.
Understanding production methods explains how this clean energy vector will scale up at gigawatt levels, setting the stage for examining the electrolysis process in detail.
How Is Green Hydrogen Produced Using Electrolysis?
Green hydrogen production relies on splitting water into hydrogen and oxygen via an electric current. This process takes place in an electrolyzer stack, where water flows through an anode and cathode separated by an ion‐conducting membrane or alkaline medium.
Key steps in the electrolysis process include:
- Supplying renewable electricity to generate an electric field across electrodes
- Oxidizing water at the anode to release oxygen gas and protons
- Conducting protons through the membrane to the cathode side
- Reducing protons at the cathode to form hydrogen gas
- Collecting pure hydrogen for storage or distribution
This step-by-step mechanism highlights the role of specialized electrolyzer technology and leads into why PEM systems are central to high-efficiency green hydrogen plants.
What Makes PEM Electrolyzer Technology Central to Siemens Energy’s Approach?
Proton Exchange Membrane (PEM) electrolyzers use a solid polymer membrane to conduct protons while separating gas streams, offering high current density, rapid dynamic response, and compact footprint. This enables fast ramp-up to match variable renewable power and modular scaling across multiple units.
Core benefits of PEM electrolyzers:
- High Efficiency: Low voltage losses and high purity output
- Dynamic Operation: Rapid load-following capability under fluctuating generation
- Compact Design: Reduced balance-of-plant size and simpler maintenance
These advantages drive Siemens Energy’s selection of Silyzer and Elyzer PEM stacks for global facilities, seamlessly integrating renewable power and enabling grid-friendly operation.
How Does Renewable Energy Power Green Hydrogen Production?
Green hydrogen facilities harness electricity from solar arrays and wind farms to sustain electrolyzer operations. By aligning power purchase agreements (PPAs) with renewable generators, operators secure low-carbon electricity at predictable prices, ensuring consistent hydrogen output without grid emissions.
These renewable inputs reduce hydrogen production costs over time while reinforcing the integration of electrolyzers as virtual power plants, laying the groundwork for Siemens Energy’s next generation of green hydrogen projects.
