Large-Capacity LH₂ Storage Solution

Engineered for massive liquid hydrogen storage with on-site construction, ultra-low BOG, and optimized total cost of ownership.

1.Product Overview:

Designed specifically for the burgeoning hydrogen economy, our high-performance fixed-facility spherical pressure vessels adopt advanced high-vacuum multilayer insulation (HVMLI) or vacuum powder insulation technology. They deliver exceptional cryogenic insulation performance and long-term operational stability. Available in capacities from 200 m³ up to 3,000 m³, the series complies with international standards (ASME or enterprise standards) and is field-erected to overcome transport limitations.

The on‑site construction approach enables truly large‑diameter spheres, significantly reducing the number of storage units needed, minimizing land occupation, and lowering both capital expenditure (CAPEX) and operational expenditure (OPEX). With its unparalleled large-capacity, high-efficiency storage, the CIMC ENRIC liquid hydrogen spherical tank is the core infrastructure for large‑scale LH₂ storage and continuous supply – serving liquid hydrogen plants, large LH₂ storage hubs, space launch centers, and providing reliable support for energy, chemical synthesis, metallurgy and other industries.

As a landmark breakthrough, CIMC ENRIC has successfully developed China’s first domestic high‑vacuum multilayer insulated liquid hydrogen spherical tank, marking a historic milestone for the hydrogen value chain and demonstrating a leap forward in efficient large‑scale LH₂ storage technology.

2.Why Choose the LH₂ Spherical Tank? – Key Advantages

In large‑scale storage scenarios such as liquid hydrogen plants, conventional LH₂ bullet tanks or vertical vessels are constrained by transport dimensions, making it difficult to meet large volume requirements with a single vessel. Using multiple units in parallel leads to excessive footprint, higher system redundancy, and increased construction plus long‑term maintenance costs.

The LH₂ Spherical Tank (field‑erected) solves these challenges perfectly:

Feature	LH₂ Spherical Tank (Onsite Construction)	Conventional LH₂ Tanks (Multiple Parallel Units)
Single‑unit capacity	Large (customizable, no transport limitation)	Limited (strictly constrained by shipping size)
Large‑volume Storage solution	Single or very few spheres needed	Many tanks required in parallel
Specific CAPEX (per m³)	Lower (less materials, simpler system)	Higher (more materials, complex system)
Footprint	Small	Large
BOG evaporation loss	Very low (lower surface‑to‑volume ratio, minimal heat leak)	Relatively higher
Application	LH₂ plants, large LH₂ hubs, spaceports	Small/medium refueling stations, distributed storage

Additional operational benefits:

Integrated intelligent control system enables centralized monitoring and automated operation, ensuring stable conditions and significantly lowering lifecycle OPEX.
Excellent insulation performance – advanced high‑vacuum multilayer design keeps boil‑off gas (BOG) to an absolute minimum, improving overall hydrogen efficiency.
Proven reliability – engineered and built to rigorous standards (ASME or enterprise code), with long‑term stability demanded by critical industries.
