Los Alamos National Laboratory offers GetterGauge hydrogen-getter technology for licensing

Los Alamos National Laboratory is offering its GetterGauge hydrogen-getter technology for commercial licensing, rather than soliciting a purchase of products or services. - Opportunity: Exclusive and non-exclusive licensing agreements are available through the Department of Energy technology licensing program. - Technology: GetterGauge changes color to indicate remaining hydrogen-capture capacity without opening or damaging a sealed device. - Capabilities: It can store up to 1,200 cubic centimeters of hydrogen per gram, captures hydrogen at very low pressures without activation, and can selectively capture hydrogen in the presence of helium, nitrogen, argon, and methane. Its capture rate can be adjusted through catalyst loading, and the material can be incorporated into plastics and polymers. - Potential applications: Nuclear systems, microelectronics and semiconductor packaging, aerospace and satellites, medical implants, imaging equipment, and vacuum-insulated products. - Readiness and intellectual property: Technology Readiness Level (TRL) 4; a U.S. patent is pending. - Procurement details: No purchase quantity, product part number, vendor, or procurement requirement is identified.

Description

A Capacity Indicator for Hydrogen Getters

Imagine a hydrogen getter that tells you how much protective life it has left, simply by changing color, so engineers can read remaining capacity at a glance without ever opening the sealed device it guards. GetterGauge pairs that built-in gauge with a level of selectivity most getters cannot match, pulling hydrogen out of a sealed space while ignoring the helium, nitrogen, argon and methane around it and continuing to work. even at pressures a thousand times below atmospheric. Underpinning the color-change readout is a material that holds up to roughly three times more hydrogen than fielded products, works from below freezing to well above the boiling point of water, and needs no activation step before use. Because the material is friendly to plastics and polymers, it can be shaped to fit the device rather than forcing the device to fit the getter, opening the door to smaller, longer-lived and lower-cost sealed systems across electronics, medicine, aerospace and energy.

Challenges

Sealed and vacuum systems fail early when hydrogen accumulates inside them, because hydrogen corrodes metals, embrittles structural parts and can build toward a dangerous release. Getters exist to prevent that outcome, yet the versions on the market carry a stubborn set of limitations: The best ones store only about 350 cubic centimeters of hydrogen per gram, perform within a narrow temperature window, generally demand a separate activation step, lack selectivity against background gases and cost more than product designers would like. A second, quieter problem compounds the first: Once a getter is sealed inside a satellite, implant or waste container, there has been no non-destructive way to learn how much hydrogen it has already taken up. Engineers are left to guess at remaining protection, which forces a hard trade between replacing parts early on a cautious schedule and risking a silent loss of protection, and both choices add cost and uncertainty to equipment that is expensive to build and hard to reach.

Problems Solved

This new getter family answers the capacity and performance limits directly. Storage rises to as much as 1200 cubic centimeters per gram. The operating range widens to span below 0 through above 100 degrees Celsius. The materials capture hydrogen at very low pressures, thousands of times lower than the atmosphere pressure, without the customary activation step. Hydrogen is taken up selectively, even when helium, nitrogen, argon or methane is present and while allowing the uptake rate to be dialed in through catalyst loading. The feature that sets these getters apart, however, speaks straight to the inspection gap: A colorimetric response turns the material itself into a gauge, changing color or brightening as it absorbs hydrogen so that remaining capacity can be read visually and without destroying the part. A getter that reports its own remaining life converts the old guessing game into a simple visual check, letting operators retire a part when it is genuinely spent rather than on a conservative calendar.

Advantages

Reports its own remaining capacity through a simple, non-destructive color change, with no need to open or sacrifice the sealed part Turns replacement from a cautious calendar guess into a visual check, so parts are retired only when genuinely spent Delivers strong core performance in one package; up to roughly three times the hydrogen of conventional getters, a wide temperature range and no activation Captures hydrogen selectively at pressures far below atmospheric, ignoring helium, nitrogen, argon and methane Allows designers to tune the capture rate by adjusting catalyst loading to match the application Blends into plastics and polymers for flexible shapes and smaller footprints
