Nigeria is the largest natural gas producer in Africa, yet more than half of its population still lacks stable electricity supply. With the growth of the economy, electricity demand is constantly increasing. Gas power generation has gradually become the core solution for Nigeria to address the issue of power shortage. Stable and secure liquefied natural gas (LNG) storage facilities are the foundation for ensuring stable power supply to power plants. Therefore, professional LNG storage tank solutions have also become an inevitable choice in the industry.
For different-sized and location-based power plants in Nigeria, the current mainstream LNG storage tank solutions have been adapted for local use: For large centralized power plants located near coastal LNG receiving stations, large-capacity full-capacity cryogenic storage tanks are mostly adopted. Each storage tank can have a capacity of 100,000 to 200,000 cubic meters. The storage tanks employ advanced double vacuum multi-layer insulation technology. The storage temperature of liquefied natural gas is -162℃, and its daily evaporation rate is less than 0.05%. This can minimize the loss of liquefied gas and ensure the stable and continuous supply of gas to the power plant. For small and medium-sized distributed power plants in remote northern areas, modular small-scale LNG storage tanks with flexible volume and short construction period are more popular.They can handle the local infrastructure deficiencies and project funding shortages with great ease.
Chinese low-temperature gas equipment enterprises have mature technologies and their services cover the entire industrial chain. Moreover,
in one region of Nigeria, they have already “accumulated” sufficient on-site experience.The largest LNG low-temperature storage tank project under construction in Africa was independently designed and constructed by the Chinese team. In response to the unique climatic conditions in Nigeria, such as high temperatures, high humidity, and a seven-month-long rainy season, the project team innovatively improved the treatment process of the mud in the tank foundation and the anti-corrosion process of the external tank body. They successfully developed intelligent lifting technology, achieving precise positioning of the tank dome at the millimeter level using tonnage-level tank lifting equipment. This not only successfully solved the ‘critical’ technical problems encountered in similar projects in Africa during construction, but also shortened the overall construction period by 12%. … It has set new benchmarks for technology and efficiency in the construction of large-scale liquefied natural gas tanks in Africa, as well as in the construction of a wide range of high-difficulty projects with special climates.
Nigeria’s power plant has chosen the LNG storage tank solution. There are three key points that cannot be overlooked:
First, it must be adapted to the local geological and climatic conditions. For instance, the soft soil foundation in the eastern coastal areas, combined with the continuous rainfall that lasted for several months in the southeast region, can be regarded as “extremely adverse weather conditions” in the industry. When designing, these factors must be fully taken into account, and other regions’ mature solutions should not be simply applied.
Secondly, it is also recommended to consider choosing suppliers who can provide services throughout the entire life cycle of the project.The insulation layer maintenance of LNG storage tanks and the inspection of core components all require professionals. A local service team can significantly reduce operational risks.
Thirdly, it is necessary to strike a balance between initial investment and long-term returns. Large storage tanks are suitable for large-scale projects with long-term operation, while small and medium-sized modular storage tanks are more suitable for distributed projects with limited investment. The matching should be based on the power generation scale and gas source conditions.
As Nigeria accelerates its energy structure adjustment and expands the proportion of local natural gas power generation, the demand for professional LNG storage tank solutions will continue to grow. Reliable storage infrastructure can not only improve the local power supply situation but also lay a solid foundation for Nigeria’s clean energy transition.
