Fullcryo supported CNOOC in successfully completing the world’s longest marine transportation and terminal utilization test for liquid hydrogen

It was learned from CNOOC (China National Offshore Oil Corporation) that the world’s longest marine transportation demonstration project for liquid hydrogen, carried out by CNOOC's Gas and Power Group, successfully completed its first transoceanic journey with a tonnage-level shipment. The vessel, loaded at the Port of Rotterdam in Europe on September 4 (local time), traversed the Atlantic Ocean, the Cape of Good Hope, and the Malacca Strait, arriving smoothly at Shenzhen's Yantian Port on October 21. Subsequently, the liquid hydrogen was transported overland to the Fullcryo Zhongshan Delta Gas Complex for terminal utilization testing. Following a process of vaporization and refilling, the first shipment of high-purity hydrogen gas produced from this transoceanic transportation project was dispatched to a hydrogen refueling station on October 23. This milestone signifies the successful completion of terminal utilization testing for the first international long-distance transoceanic liquid hydrogen demonstration project, in which Fullcryo has participated. The project’s implementation positions China as a pioneer in the emerging field of long-distance transoceanic hydrogen transport and utilization.

The transition to clean energy has become a global consensus, with hydrogen recognized as a clean, efficient energy carrier and a vital component of future national energy systems, essential to China’s green, low-carbon transformation. This cross-ocean transportation and terminal utilization test for liquid hydrogen has established an innovative technology chain for the global development of the hydrogen industry, demonstrating the substantial potential of liquid hydrogen technology for large-scale, long-distance hydrogen transport. With high energy density and transport efficiency, liquid hydrogen is set to be key for future large-scale hydrogen applications. In fuel cell applications specifically, liquid hydrogen can significantly extend cell life, allowing for low-temperature storage and precise multi-condition supply, showcasing high technological and application value.

As a participant in this demonstration project, Fullcryo leveraged its expertise in liquid hydrogen technology development, engineering management, and operations to collaborate with CNOOC’s Gas and Power Group in developing a research and testing platform for liquid hydrogen. Fullcryo provided technical support at critical demonstration points, including on-site commissioning of liquid hydrogen ISO tank containers, vaporization and refilling, and hydrogenation applications. Drawing on the core technological achievements of the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences, Fullcryo has achieved independent R&D and integration capabilities for large-scale hydrogen liquefaction equipment, offering customers a comprehensive hydrogen energy solution covering production, purification, liquefaction, storage, transportation, and application. Fullcryo’s 1.5-ton-per-day hydrogen liquefaction plant, with independently developed intellectual property, has passed expert technical evaluation, achieving energy efficiency on par with similar international equipment and successfully applied in overseas projects. The first domestically produced 5-ton-per-day large hydrogen liquefaction unit, jointly developed by Fullcryo and the Institute of Physical and Chemical Technology, has successfully produced liquid hydrogen with a 98.66% parahydrogen content and a liquefaction system efficiency of 12.98 kW·h/kg of liquid hydrogen (including nitrogen loss), reaching internationally advanced standards in overall performance.

With the robust growth of the hydrogen industry, Fullcryo, as a proponent of green, low-carbon development, is committed to delivering independently controlled, green, efficient, safe, and reliable cryogenic and gas products. The company strives to realize large-scale hydrogen applications and enhance carbon neutrality and cost efficiency, aiming for sustainable development from cryogenics to green energy. According to forecasts from the International Renewable Energy Agency, hydrogen is expected to account for over 30% of international trade by 2050. As a global leader in hydrogen production, China’s annual production is projected to reach 40 million tons. Against the backdrop of global energy structure transformation and the gradual improvement of domestic hydrogen export regulations and systems, liquid hydrogen is expected to become an important energy export commodity, contributing to the advancement of global clean energy and supporting the realization of global emission reduction goals.
