FuseBlox System for Robotically-Assisted Cryogenic Applications

SpaceWorks proposes FuseBlox CryoFlow, a modular cryogenic fluid interface designed for in-space refueling and ground infrastructure applications, addressing NASA’s identified Capability Gap for Moon-2-Mars objectives. CryoFlow integrates fluid transfer, power, and data pass-through in a compact form factor, leveraging proven FuseBlox platform technologies. IGNITE Phase 2 funding will support the development and testing of a ground-rated prototype. By serving multiple market verticals with a scalable platform, CryoFlow is poised to enable next-generation cryogenic flight platforms across the space industry.

The FuseBlox CryoFlow system directly addresses NASA’s identified Capability Gap for low-leak cryogenic couplers, as outlined in Topic H102.24: Leak-Free Cryogenic Valves and Quick Disconnects. CryoFlow is an end-to-end platform designed to enable reliable, autonomous transfer of cryogenic fluids, such as liquid hydrogen (LH2) and liquid oxygen (LOX), between spacecraft or ground systems. Unlike traditional one-off, bespoke interfaces, CryoFlow offers a modular, plug-and-play solution that is scalable, cost-efficient, and tailored to meet the demands of emerging space servicing markets. CryoFlow’s applications span critical NASA mission architectures, including in-space refueling, lunar surface operations, and interplanetary transport. Cryogenic propellants are essential for long-duration exploration and deep-space propulsion due to their superior performance, but their management is challenging due to extreme temperatures and boil-off risks. CryoFlow’s robust, repeatable, and safe transfer interfaces mitigate these challenges, enabling spacecraft to be refueled on orbit or on the Moon and Mars. This capability unlocks mission architectures constrained by launch mass and tank sizing, supporting reusable upper stages, in-space depots, and interplanetary transport vehicles. FuseBlox CryoFlow has significant potential beyond NASA, addressing critical needs in commercial, military, and international space markets. Its modular, scalable design makes it ideal for supporting emerging NewSpace industries, including satellite servicing, in-space logistics, and orbital refueling. Large private/commercial entities are actively developing refuellable upper stages and orbital platforms, which require reliable cryogenic fluid transfer systems. CryoFlow’s ability to minimize leakage, ensure structural robustness, and enable quick emergency demating positions it as a key enabler for these applications. Beyond space, CryoFlow’s technology has terrestrial applications in industries such as precision manufacturing, energy generation, and machine servicing. Its ability to handle cryogenic fluids with high reliability and minimal spillage makes it suitable for advanced robotics, industrial cooling systems, and clean energy solutions. These non-NASA applications highlight CryoFlow’s versatility and its potential to drive innovation across multiple sectors.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
