When waves surge over the deep sea, steel islands are quietly transforming. The offshore platforms that relied on fossil fuels in the past are now attempting to transform the roaring sea breeze and scorching sunlight into the cleanest hydrogen fuel on site. A silent energy revolution has begun on a blue land.

Recently, CNOOC's CNOOC subsidiary, CNOOC Engineering, has independently developed a specialized PEM electrolysis water hydrogen production device for offshore use, and completed a floating platform oscillation environment test, achieving new progress in the development of the hydrogen energy industry.

National Strategy for Hydrogen Energy Rise

Hydrogen energy is the core track for enterprises to transform into comprehensive energy service providers in the development plan of CNOOC1566, and the enterprise is laying out the research and development of hydrogen energy production, storage, and transportation technology throughout the entire chain.

In the early years, the development of hydrogen energy was slow due to high costs, and the strategic position of domestic hydrogen energy continued to rise under the background of dual carbon. Multiple national level plans and energy regulations have clearly defined the positioning of the hydrogen energy industry, with a target of 2 million tons of renewable energy hydrogen production by 2030. At present, 66 countries around the world have introduced hydrogen energy plans, and the growth rate of domestic green hydrogen production capacity is leading the world.

Breakthrough in diversified hydrogen production technology

The technology of various links in hydrogen energy still needs to be improved to reduce costs, and CNOOC has achieved key results in multiple hydrogen production routes.

Megawatt level PEM hydrogen production equipment: self-developed low precious metal catalyst, reducing consumables by 30%; Integrated photovoltaic hydrogen production system to achieve green electricity and green hydrogen recycling.

Offshore dedicated PEM hydrogen production equipment: suitable for offshore shaking and high salt spray environments, can withstand typhoons of level 17, has lower hydrogen production energy consumption than traditional equipment, and is suitable for offshore wind power hydrogen production.

Megawatt level desalination free seawater hydrogen production equipment: the world's first complete set of equipment that directly electrolyzes without seawater desalination, producing high-purity hydrogen gas. Its modular design is suitable for offshore platforms.

Small scale sled mounted natural gas hydrogen production equipment: highly integrated small devices that can flexibly supply hydrogen to various scenarios nearby.

Synchronized tackling of storage and transportation applications

Storage and transportation are the main bottlenecks in the hydrogen energy industry chain, and enterprises are simultaneously tackling the core technologies of hydrogen storage and power generation equipment.

Organic hydrogen storage: Achieve ton level mass production of dehydrogenation catalysts, solve the problem of performance degradation in mass production, and adapt to ocean storage and transportation.

Ten thousand cubic meter liquid hydrogen storage tank: relying on LNG low-temperature technology for independent research and development, certified by the classification society, to achieve large-scale hydrogen storage.

Megawatt level SOFC fuel cell: selected as a national hydrogen energy pilot, with better power generation efficiency than traditional units and a wide range of fuel adaptability. It can be used for combined heat and power supply on offshore platforms and LNG stations, and the team is actively researching high-power models.

From the catalyst formula in the laboratory to the steel equipment that can withstand rough waves, CNOOC is breaking through the two veins of green hydrogen at sea. With the gradual breakthrough of storage and transportation bottlenecks, this blueprint covering the entire industry chain of hydrogen production, energy storage, and power generation will write the toughest footnote for the energy self-sufficiency of the Far East Sea.Editor/Gong Ziwei
