GREEN HYDROGEN HAS MANY USES
Green hydrogen (H2) is a versatile energy carrier that can be applied to decarbonize a wide range of sectors. It can be used directly or in the form of its derivatives like methanol, ammonia, or eFuels to replace fossil fuels like coal or gas.
Only around 30% of global carbon dioxide (CO2) emissions originate from power generation which can be decarbonized via electrification.
The other 70% of CO2 emissions originate from transport, industry, buildings, and others.
Hydrogen Production Using PEM Electrolysis and Hybrid Turbines
Hydrogen, touted as a key player in the transition to a sustainable energy future, can be produced through Proton Exchange Membrane (PEM) electrolysis. This process involves splitting water into hydrogen and oxygen using electricity. When paired with seawater as a source, the water must first undergo desalination to remove salts and impurities, ensuring the purity required for efficient PEM operation.
Water and Energy Demands for Hydrogen Production
Producing hydrogen via PEM electrolysis is energy-intensive, requiring substantial amounts of both water and electricity. To produce 1 kilogram of hydrogen, approximately 9 liters of pure water and significant electrical input are needed. Meeting these requirements sustainably is critical, especially when using seawater as the source.

Combining hybrid turbine technology with PEM electrolysis and seawater desalination represents a robust pathway for hydrogen production. This integrated approach not only addresses water and energy demands but also paves the way for hydrogen to serve as a clean energy carrier for transportation, industrial applications, and power generation. Investing in this infrastructure today can ensure a sustainable and resilient energy future for tomorrow.
Dual Benefits of Desalination: Supporting Hydrogen Production and Community Needs
Desalination, the process of converting seawater into fresh water, is essential for producing hydrogen through Proton Exchange Membrane (PEM) electrolysis. However, the benefits of desalination extend beyond hydrogen production. The purified water created through this process can be utilized for essential community and agricultural purposes, such as providing clean drinking water or supporting farmers during droughts.
Pure Water for Drinking and Agriculture
Drinking Water:
- The desalination process produces high-quality, purified water. This water, after minimal additional treatment, can be directed into drinking water supplies, alleviating water scarcity issues in arid or drought-prone regions.

Agricultural Support:
- Fresh water from desalination can be diverted to support irrigation systems, helping farmers sustain crops during dry seasons or in areas with naturally saline groundwater.
- With agriculture being heavily impacted by climate change, desalinated water offers a reliable resource for maintaining food production and supporting livestock.
Integration with Hydrogen Production
By co-locating desalination plants with PEM hydrogen production facilities:
- Shared Resources: The fresh water generated can serve dual purposes, powering the electrolyzers for hydrogen production while also being allocated to drinking water supplies and farming needs.
- Efficient Use of Infrastructure: Shared pipelines and storage systems reduce costs, making the desalination process more economically viable.
- Environmental Benefits: Reusing the desalinated water for multiple purposes minimizes waste, ensuring a sustainable approach to managing both water and energy resources.
Addressing Water Scarcity with Hydrogen Technology
In areas facing critical water shortages, the integration of desalination and PEM technology presents a game-changing opportunity. As nations push toward hydrogen as a clean energy carrier, the parallel benefit of increasing freshwater availability could improve millions of lives:
- Improved Livelihoods: Farmers would have access to reliable water sources, reducing dependency on unpredictable rainfall.
- Enhanced Resilience: Communities would be better equipped to handle water crises caused by climate change, ensuring access to safe drinking water even in the driest conditions.
Investing in desalination not only supports clean energy initiatives but also strengthens water security, creating a win-win scenario for sustainable development and community well-being.
