海南首个万吨级“海风—绿氢—绿色甲醇”示范项目落子儋州洋浦Hainan's first 10,000-ton-level 'Offshore Wind–Green Hydrogen–Green Methanol' demonstration project lands in Yangpu, Danzhou

Recently, at the Danzhou special event of Shenzhen's "Dual Carbon" practice themed "Strengthening through Green", Hainan Shenergy New Energy Co., Ltd. disclosed a clear green energy chain: offshore wind power generates green electricity, green electricity produces green hydrogen, green hydrogen coupled with carbon dioxide synthesizes green methanol, and finally it is supplied to international navigation vessels at Yangpu Port. This means that Yangpu in Danzhou is turning "a gust of wind" into a green liquid fuel that can be stored, transported, traded, and exported.

Supporting this chain is the 1.2 million kilowatt offshore wind power project built by Shenergy Group in Hainan. Among them, the first phase of 603 MW will be fully connected to the grid by 2025, and the second phase of 576 MW is planned to be put into operation by the end of 2026. Once fully completed, the annual power generation will exceed 3.8 billion kilowatt-hours. With the increase in power generation, utilization becomes the core issue. The company's solution is "local conversion," with the construction of Hainan's first green hydrogen-based energy full industrial chain demonstration project based on offshore wind power, deeply linking the CZ2 offshore wind power with hydrogen production and methanol production projects: the wind farm generates green electricity, the hydrogen production project consumes electricity locally, and then it is further used to produce green methanol and plan for green ammonia downstream.

The challenge lies in 'the wind may fluctuate, but chemical processes must remain stable.' Offshore wind power varies with the weather, while hydrogen and alcohol production require continuous operation. The company addresses this through 'coordination': matching electrolyzers with different characteristics to balance output, using hydrogen storage facilities for short-term buffering, relying on the public power grid for extreme backup, and employing intelligent scheduling based on wind forecasting, thereby converting fluctuating offshore wind into stable production capacity.

The project is implemented in the Yangpu Green Petrochemical Functional Area, using green hydrogen and biomass-derived carbon dioxide to synthesize green methanol in one step. Renewable electricity accounts for over 97%, meeting ISCC international green certification. The project has completed registration, land bidding will be completed in September this year, construction will start within the year, and by the end of 2027, infrastructure and commissioning are planned to be completed, achieving large-scale production and forming a continuous production capacity of tens of thousands of tons of green methanol. This is also the first tens-of-thousands-of-tons green hydrogen-to-methanol project truly implemented in Hainan.

The more critical underlying factor is international shipping demand. The IMO Net Zero Regulations and the EU carbon market are pushing the shipping industry onto a decarbonization path; the industry expects that by 2030, global demand for green methanol will be about 12 million tons, with around 450 methanol-powered ships. According to reports, the demand for refueling on international routes alone reaches 40,000 to 50,000 tons, with EU routes being the main battlefield. It is reported that on September 15, the company completed continuous refueling of 11,000 tons in its 100,000-ton-class green methanol project in Shanghai.

Why Danzhou Yangpu? Hainan plans to add 12.3 million kilowatts of offshore wind power by 2030, and the free trade port's 'zero tariff' on the import of large equipment can lower construction costs; Yangpu is located at the shipping hub of the Western Land-Sea New Corridor, with the potential to refuel green fuel on a million-ton scale. Shengneng Group also plans to use the demonstration project to build Hainan's green fuel innovation testing platform, reserve general interfaces, verify offshore wind hydrogen adaptability, the integrated operation of electricity, hydrogen, and methanol, as well as multi-stage coordination with the power grid, to establish standards and accumulate data for 100,000-ton and million-ton projects.

According to the company's planning concept, once the "wind power-to-hydrogen — methanol synthesis — international certification — global refueling" model is successfully implemented, the experience will be replicated in ports such as Qingdao, Shanghai, Ningbo, and Shenzhen. The fluctuating sea winds are being transformed into stable energy assets in Yangpu, Danzhou, also paving a replicable new path for large-scale renewable energy consumption in Hainan.
