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.
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 (On-site 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.
| Parameter | Value / Range |
| Effective storage volume | 200 m³ – 3,000 m³ (customizable on request) |
| Insulation type | High‑vacuum multilayer insulation (HVMLI) or vacuum powder insulation |
| Design code | ASME, or applicable enterprise standard |
| Operating medium | Liquid hydrogen (LH₂) |
| Construction method | On‑site field erection, tailor‑made for client site |
| BOG evaporation rate | Ultra‑low, optimized based on volume and insulation design |
| Control system | Integrated intelligent control system for centralized monitoring and automated operation |
*All products are manufactured under a strictly controlled quality management system, ensuring safety, traceability, and global acceptance.
