From laboratory-scale cryostats to the Space Shuttle external tank, our engineers have experience in your cryogenic propellant storage and distribution needs, including LOX, LNG, and LH2. 

Store more propellant in your vehicle tanks by cooling it close to the triple point,  or even as slush. Densified propellants have a greater total impulse, longer storage duration, and additional cooling  capacities. Eta Space is the industry leader in analysis, design, and operation of LOX and LH2 densification units, including IRAS, ejector, and vacuum  pumping systems.

The transition from carbon-based fuels to a hydrogen economy is limited by the energy requirements for production and liquefaction. Eta Space is on the forefront of clean energy solutions with a series of advanced hydrogen liquefiers that reduce hardware requirements and maximize energy efficiency. From 15 liters per day, to one ton per day, Eta Space has solutions to fit your liquid hydrogen needs. 

In-space propellant resupply is a critical enabling technology for sustainable space exploration. Eta Space is developing  propellant depots for orbital and lunar polar locations, with sizing for a variety of mission architectures. From Aerogel to Zero Boil Off,  we develop and deploy advanced cryogenic systems critical to the future of space.

When every milliwatt is precious, Eta Space is ready to optimize your systems for maximum efficiency. Our engineers are experts in both active and passive thermal  management for applications of minimizing heat leak and managing heat flow.

Integrated Refrigeration and Storage of cryogenic propellants eliminates storage and transfer losses and enables complete control of the fluid state anywhere on the saturation curve. Eta Space engineers pioneered the IRAS technology, now being added to the worlds largest LH2 storage tank at KSC LC-39B.
