Our technology uses hydrogen as a refrigerant combined with proprietary, patent pending, nanostructured heat sinks to provide highly efficient, direct-to-chip cooling. Hydrogen gas has the highest thermal conductivity of all known gases (10x better than air) which makes it an ideal choice for high efficiency cooling. We estimate that a hydrogen system could enable a cooling power usage effectiveness (PUE ) of 1.05.
A direct-to-chip hydrogen cooling system reduces cooling noise by up to 95%, can be used with zero water setups including atmospheric heat rejection, and offers a smaller footprint than liquid direct-to-chip and other cooling technologies. Our system also offers a lower risk to asset damage over existing high efficiency cooling technologies such as direct-to-chip liquid or immersion cooling.
62 Cool is actively seeking a TUV certification for our system. Our technology deploys hydrogen at lower pressures than other hydrogen applications, and it includes numerous built in safety features. Furthermore, our system uses small quantities of hydrogen gas relative to the data center environment making our system inherently safe.

Safety is top of mind for the 62 Cool team. To that effect, we are pursuing TUV certifications for our product suite to provide tangible, industry-backed safety guarantees. We will also be working closed with the National Fire Protection Association (NFPA) to ensure we operate within their criteria for hydrogen (NFPA-2) and their criteria for electronics (NFPA-70, NFPA-496).
In addition to future TUV certification, our system has several features which make it inherently safe. Our hydrogen closed-loop system operates at low pressures relative to other hydrogen applications. Furthermore, the total amount of hydrogen located inside the system is limited. Even in the event of a total release, the total hydrogen is well below the 4% total room volume limit. Our system also includes a number of check valves and flame arrestors which make the risk of total release essentially impossible.
Water-based cooling introduces leaks that can destroy electronics, requires massive piping and pumps that fail under pressure, and creates slip, flood, and corrosion hazards. Hydrogen, by contrast, is contained in small-diameter, high-integrity tubing with no liquid present. Any leak is a gas that rises and dissipates rapidly, and the flame arrestor technology ensures that even a worst-case ignition event is confined and extinguished instantly. The net result is dramatically lower operational risk, lower insurance premiums, faster project approvals, and greater peace of mind. Internally, we summarize the risk profile with the simple, powerful statement that the system is "safer than water".
