SKYRE develops and manufactures innovative products based on a proprietary, low-cost large format electrochemical platform. Developed for NASA, our H2RENEW solid state device efficiently separates and compresses hydrogen for industrial H₂ recycling, H₂ energy storage and fueling applications.

Develop a system to make propellant from permanently frozen water located at the Moon’s poles.

This includes processes to separate the hydrogen and oxygen, keep the product extremely cold and use hydrogen as a refrigerant to liquefy oxygen.

We’re delivering bifunctional regenerative electrochemical air transformation for human environments (BREATHE)

In the closed-loop Space Station Environmental Control and Life Support System (ECLSS), metabolically-generated carbon dioxide is collected and concentrated. The CO2 is reduced with hydrogen, produced by a hydrogen/oxygen generator or electrolyzer, in a Sabatier reaction, forming methane and water. This results in the recovery of < 50% of the oxygen from the water formed in the Sabatier, requiring resupply missions compensate for the remaining oxygen.

As NASA looks forward to more extended manned-exploration missions, the feasibility of resupply diminishes, necessitating closing the ECLSS life support loop for greater oxygen recovery. SKYRE has teamed with the University of Connecticut (UCONN) to develop an electrochemical hydrogen separator to recover hydrogen from the Plasma Pyrolysis Assembly (PPA) effluent and return it to the Sabatier reaction to form more water, and thus more oxygen, driving further closure of the air revitalization system.  The ultimate goal is recovery of all of the oxygen needed for crew consumption.

SKYRE and UCONN have identified the following performance targets for the program:

We’re developing critical hydrogen fueling infrastructure on the moon.

A leader in the development of electrochemical systems for government and commercial customers, SKYRE is working with Eta Space – an expert for in-space cryogenic fluid management technologies – to develop the first hydrogen fueling plant on the Moon. With imperatives of sustainability and efficiency, it will produce “green” (a near zero-emissions process), paving the way for the infrastructure needed here on Earth for emerging hydrogen economies.

“Sustainability is partially enabled by the ability to generate hydrogen fuel right on the moon’s surface with almost non-existent resources, as opposed to having it delivered from Earth.” Says SKYRE CEO, Dr. Trent Molter. “One resource available for use is ice in the permanently-shadowed craters of the Polar regions. Based on a proprietary electrochemical platform, SKYRE will electrolyze the ice water into its hydrogen and oxygen components and our H2RENEW™ will then compress and liquefy the hydrogen for use as fuel.”

Critical to this process is having a robust refrigeration system to liquefy the hydrogen, which in turn, requires a compressor to pressurize it for use as a fuel. “Typically, it’s very hard to compress a small molecule like hydrogen, making traditional mechanical compressors very inefficient and unreliable for the task and ultimately, not able to produce green hydrogen.” Says Eta Space CTO, Dr. William Notardonato. “The H2RENEW is a solid-state system that requires little or no dependency on logistics to operate efficiently and has no moving parts which results in greater reliability and increased cost-efficiencies. It hits on all marks, making it the ideal fit for the demands of lunar liquefaction.

Status Comment / Notes

As of 2024, focus is on terrestrial systems, but some space projects.
