NEW AGE OF LIQUID HYDROGEN
Alpha(α) Series
Alpha series hydrogen liquefiers provide flexible LH2 production capacity up to 100 kg per day with Plug-N-Go convenience for small LH2 quantity users. A unique multi-cryocooler-driven design offers extreme portability and easy operation while maintaining the highest efficiency of 30 kWh per 1 kg of LH2 in its class.
The system can be easily mounted on ISO containers and trucks and deployed on project sites with minimum installation time. The automated hydrogen recirculation loop provides efficient direct hydrogen liquefaction and zero hydrogen loss for unlimited storage time.
For all the alpha series, multiple safety devices and emergency shut-down come as standard safety features. LN2 precooler and ortho-para hydrogen converter are optional to increase liquefaction and storage performance.
Alpha series are perfect all-in-one LH2 solution for your LH2 projects included, but not limited to,
- Lab scale LH2 production facility for R&D projects
- A small fleet of LH2 powered drone refueling
- Integration with On-site hydrogen production and LH2 storage system
- Mobile LH2 refueling station
Beta(β) Series
MetaVista has accumulated extensive experience on various hydrogen liquefaction plant designs for decades. Recently, MetaVista has successfully developed a noble reverse-Brayton helium refrigeration cycle which doesn’t require any LN2 or LNG precooler for hydrogen liquefaction plant. The so-called “Dry” hydrogen liquefier design significantly reduces system complexity, CAPEX and OPEX compared to conventional hydrogen liquefaction plants while demonstrating the same or higher efficiency as traditional LN2/LNG precooled LH2 plant.
Beta series hydrogen liquefaction plant employs the innovative “Dry” LH2 plant design that can provide LH2 production capacity of 0.1~ 1 ton per day at high efficiency. Hydrogen feed gas is separated from the helium refrigeration loop to accept lower purity hydrogen feed gas. It also provides a dedicated cooling loop for long-term zero-boil-off LH2 storage (IRaS) in large-scale ground storage tanks.
In Q3 2021, we have proudly delivered a complete design and engineering package for the optimized 1 TPD “Dry” LH2 plant to one of the fastest-growing hydrogen infrastructure solution providers in the world, GenH2 Corp., USA.
Employing the 1 TPD Dry LH2 plant, GenH2’s on-site hydrogen production, liquefaction, and refueling station - HyLife would be a game-changer in the hydrogen infrastructure industry in the upcoming years.
Beta Series has many unique features including, but not limited to,
- The world 1st precooler-free, “Dry” hydrogen liquefier – No LN2/LNG required at the operation site
- Modular, deployable, stackable skid design
- Easy transport / installation / maintenance cryostat design
- Optimized ballast/recovery gas management system
- Optimized impurity adsorbers for easy and low maintenance
- Fully automated PLC control and monitoring system
- Optional Ortho-Para hydrogen converters
Applications
- Stationary / Mobile Hydrogen Refueling Station for cars, trucks, and rails
- On-site hydrogen production and LH2 storage (ESS)
- LH2 bunkering for ships and boats
- LH2 refueling station for drones, air taxi and Urban Aerial Mobility
Gamma(γ) Series
MetaVista is the leading LH2 value chain solution company with decades of R&D experience in hydrogen liquefaction plant design. The Gamma Series hydrogen liquefaction plant has been re-optimized for LH2 production capacity of 5 ~ 30 TPD systems.
This modified Claude hydrogen liquefaction cycle demonstrates high efficiency of 9.5 kWh per 1 kg of liquid hydrogen. The system consists of reciprocating hydrogen compressors, expansion turbines, heat exchangers with LN2 precooling, expansion valves, and ortho-para hydrogen converters as major components. Hydrogen feed gas is purified and combined with the hydrogen of the refrigeration process.
The Gamma Series provides a separate cooling loop to control boil-off gas in large capacity ground storage tanks (zero-boil-off) as a standard feature.
Applications
- Regional LH2 production plant and LH2 tank lorry distribution
- Large Hydrogen Refueling Station (HRS)
- Large scale LH2 storage for ESS
- Fuel Cell power generation plant
- Liquid hydrogen bunkering
