For the First Time Ever, the Sea Has Been ‘Absorbed’ for Endless Energy

Seawater makes up about 97% of all water on Earth. Now, imagine if we could harness this vast, untapped resource to produce clean, green hydrogen fuel.

That future can now be a reality, thanks to a collaboration between researchers at Shenzhen University and Sichuan University in China.

Led by the visionary Academician Xie Heping, this team has developed a pioneering technology that couples offshore wind power with direct seawater electrolysis, eliminating the need for costly desalination processes.1

This breakthrough marks a significant step forward in the quest for sustainable hydrogen production, offering a potential solution to the challenges posed by the global freshwater shortage and the urgent need to reduce carbon emissions.

Successful Sea Trials

In a major milestone, the researchers conducted rigorous offshore pilot demonstrations in Fujian, China. The integrated seawater direct hydrogen production plant, powered by offshore wind, achieved an impressive 240 hours of continuous stable operation.

Third-party testing confirmed a hydrogen purity exceeding 99.9%, with an electrolysis energy consumption of just 5 kWh/Nm3 H2. This success marks the first time that such a system has been reliably demonstrated in a real marine environment.

The sea trial involved three sets of principle prototypes (0.4 Nm3/set) operating in parallel to establish an equipment system capable of producing 1.2 Nm3 H2/h. The success of this trial serves as direct verification for the future realization of large-scale seawater direct hydrogen production, with capacities ranging from 10 to 100 Nm3/h.

Cost-Competitive & Eco-Friendly

One of the most exciting aspects of this technology is its cost-effectiveness. By eliminating the need for seawater desalination, transportation, and post-treatment, the cost of hydrogen production is estimated to be only 15.89-21.49 Yuan/kg H2.

As offshore wind power continues to advance and feed-in tariffs decrease, this cost is expected to become even more competitive with traditional fossil fuel-based hydrogen production methods.

Moreover, this technology offers significant environmental benefits. By harnessing the abundant renewable energy of offshore wind and the virtually unlimited supply of seawater, it provides a sustainable and eco-friendly alternative to carbon-intensive hydrogen production processes.

Scaling Up for Global Impact

The success of this sea trial paves the way for large-scale seawater direct hydrogen production, with the potential to reach capacities ranging from 10 to 100 Nm3/h. The research team, in collaboration with Dongfang Electric Corporation, is now focusing on developing second-generation core technology and equipment with even higher efficiency, compatibility, and stability.

Their ultimate goal is to establish a global benchmark in the field of offshore renewable energy direct seawater hydrogen production. By forging an industrialization alliance with global enterprises, they aim to bring about a new era of clean energy, creating a comprehensive zero-carbon hydrogen energy development pathway that encompasses fundamental principles, disruptive technologies, localized equipment, and distinctive electrolysis hydrogen production industrial models.

A Brighter, Cleaner Future

The successful demonstration of offshore wind-powered seawater electrolysis for hydrogen production marks a significant step forward in the quest for a sustainable, low-carbon future. By harnessing the power of the oceans and the wind, this technology has the potential to revolutionize the global energy landscape, providing a clean, abundant, and cost-effective source of hydrogen fuel.

As the world continues to grapple with the urgent need to combat climate change and reduce greenhouse gas emissions, innovations like this offer a glimmer of hope. With continued research, development, and investment, we can look forward to a brighter, cleaner future powered by the inexhaustible resources of our planet’s oceans and renewable energy sources.
