Using offshore wind and solar power, China achieves 99,999% purity in green hydrogen production, eliminating desalination and reducing costs with innovative technology for offshore platforms.
In an initiative that combines cutting-edge technology and sustainability, the CenerTech refinery has announced an innovative project that uses electrolysis to produce hydrogen directly from seawater, all with renewable energy.
With an impressive purity of 99,999%, the hydrogen produced by this pilot plant represents a milestone for the global energy transition. But how did they achieve this? Let's understand the details behind this green revolution.
China's technological advancement in hydrogen production
Electrolysis is the process of splitting water molecules into hydrogen and oxygen using electricity. In the case of seawater, this technique requires more sophisticated equipment due to the complex chemical composition of the marine resource. To overcome challenges such as unwanted side reactions, CenerTech has developed a system that performs the process without the need for desalination, reducing costs and increasing efficiency.

Seawater, which is abundant and accessible, has enormous potential for hydrogen production. However, the presence of salts and other compounds can degrade catalysts and hinder the process. With advanced equipment and a focus on stability, CenerTech has managed to overcome these barriers, ensuring long-term production and reducing environmental impact.
The role of offshore wind and solar energy
To power this innovative technology, CenerTech uses offshore wind and solar energy. These energy sources are ideal because they are clean and renewable, but they also present challenges of intermittency. With green hydrogen, these variations are overcome, as the gas can be stored and transported efficiently, ensuring continuous use.
Green hydrogen is seen as the next big bet to reduce dependence on fossil fuels. In addition to not emitting carbon during its use, it offers versatility: can be used as fuel in vehicles, for energy generation and even as a raw material in industry. For the economy, it opens doors to new markets and sustainable technologies.
Efficient and portable production for offshore platforms
One of CenerTech’s greatest innovations was to develop a compact system that integrates the entire hydrogen production operation into just five containers. This makes it perfect for use on offshore platforms, expanding the possibilities for local generation in remote areas.
By eliminating the desalination step, the company not only saved resources but also ensured that the process was faster and more efficient. This approach combines technological innovation with economic sustainability, an essential balance for emerging technologies.
Expansion into remote maritime areas
The combination of direct electrolysis and renewable energy makes it possible to use this technology in areas previously considered unviable. Imagine transforming isolated maritime regions into clean energy hubs! This is the future that CenerTech envisions.
With initiatives like this, green hydrogen is getting closer and closer to becoming the world’s predominant fuel. Not only does it represent a sustainable alternative, but it could also revolutionize transportation, industry and even everyday life.
China is leading a true revolution in the clean energy sector with its hydrogen production technology from seawater. Projects like CenerTech's show that it is possible to combine sustainability, efficiency and innovation to create solutions that benefit the environment and the economy.
After I learned about the hydrogen reactor to extract it from water, I always imagined a version of it that could extract it from seawater, but now reading the article I saw that it was more complex to do it from seawater, but they finally managed to come up with this idea of extracting hydrogen from seawater, which I had already thought about a few years ago. Congratulations to them. They achieved a great feat.
