The world's first direct electrolytic hydrogen production technology and system equipment project without desalination of 110Nm³/h seawater is launched
Recently, the world's first direct electrolytic hydrogen production technology and system equipment project without desalination of 110Nm³/h seawater has been officially launched, marking a major technological breakthrough in the field of hydrogen energy. The project is led by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences and jointly promoted by many companies and scientific research institutions. It aims to solve the technical bottlenecks of high cost and high energy consumption in traditional seawater, and provide a new path for the global green energy development.
1. Technical background and breakthroughs
Traditional seawater hydrogen production requires desalination and then hydrogen production through electrolyzing water, which is complex and expensive. This project adopts "direct electrolysis without desalination" technology, using new catalysts and membrane materials to achieve efficient decomposition of seawater and reduce energy consumption by more than 30%. The following are the technical comparison data:
| Technical Indicators | Traditional hydrogen production in seawater | New Direct Electrolysis Technology |
|---|---|---|
| Energy consumption (kWh/Nm³ H₂) | 5.2-5.8 | 3.6-4.0 |
| Equipment cost (10,000 yuan/Nm³) | 12-15 | 8-10 |
| Hydrogen purity | 99.97% | 99.99% |
2. Project planning and expected results
The project is planned to be implemented in three stages, the demonstration project will be completed by 2025, and large-scale application will be achieved by 2030. The following are the key nodes:
| stage | time | Target |
|---|---|---|
| Technical verification | 2023-2024 | Complete 1000 hours of continuous running test |
| Demonstration project | 2024-2025 | Build a demonstration base of 500kg of hydrogen per day |
| Commercial promotion | 2026-2030 | Production capacity increased to 10Nm³/h level |
3. Relationship between industry influence and hot spots
Combined with global hotspots in the past 10 days, this project is highly consistent with the following trends:
| Hot Topics | Correlation analysis |
|---|---|
| EU carbon tariffs come into effect | Clean hydrogen energy can help companies reduce carbon costs |
| Japan's Fukushima nuclear sewage discharge dispute | Seawater hydrogen production technology needs to meet complex water quality challenges |
| Tesla's energy storage factory landed in Shanghai | Hydrogen energy and lithium batteries form complementary energy storage system |
4. Expert views and future prospects
Li Can, an academician of the Chinese Academy of Engineering, said: "This technology will change the global hydrogen energy industry pattern and is particularly suitable for areas with scarce freshwater resources such as islands and coastal areas." The International Energy Agency (IEA) report shows that by 2050, seawater hydrogen production may account for 15%-20% of global hydrogen energy production.
As the project advances, it is expected to drive the development of related industrial chains, including special materials, electrolytic cell manufacturing, hydrogen storage and transportation and other fields. The following are market forecast data:
| field | Market size in 2025 (billion yuan) | Annual growth rate |
|---|---|---|
| Seawater electrolysis equipment | 80-120 | 45% |
| Corrosion-resistant materials | 30-50 | 60% |
| Hydrogen energy application | 200-300 | 50% |
The launch of this project not only means technological breakthroughs, but will also accelerate the transformation of the global energy structure and provide important support for the carbon neutrality goal.
