2026 Helium Shortage: Why Recovery Will Take Years, Not Weeks

Roughly one-third of global helium supply is offline after March 2026 missile and drone strikes destroyed key production trains at Qatar’s Ras Laffan facility.1 Even when the situation in the Strait of Hormuz fully resolves, the supply damage will take years to repair. U.S. distributors are rationing supply and spot prices have skyrocketed. What’s Happening …

Helium Alternatives: Where They Work and Where They Don’t

Helium has viable substitutes for some applications (welding blends, gas chromatography) with manageable trade-offs, but no real alternative exists for MRI cooling, leak detection, semiconductor production, and a handful of specialty welding and purging jobs. The helium market is one of the most volatile in industrial gas, with prices and availability swinging hard on supply …

Solid vs. Liquid Rocket Propellants: What’s the Difference?

The main difference between solid and liquid rocket propellants is controllability. Solid propellants burn from ignition until depletion without the ability to throttle or stop, while liquid propellants offer precise thrust control through variable fuel and oxidizer flow rates. This fundamental distinction shapes everything from rocket design to mission capability, affecting storage requirements, performance characteristics, …

What Gases Power NASA’s Artemis Rockets?

NASA’s Artemis rockets run primarily on liquid hydrogen (LH₂) and liquid oxygen (LOX), the same propellant combination that powered the Space Shuttle. But propellant is only part of the picture. Helium pressurizes the fuel tanks and purges the lines. Nitrogen keeps ground systems safe and inert. Together, these four gases make every Artemis launch possible. …

How Hot Does Acetylene Burn?

Acetylene burns at approximately 3,480°C (6,300°F) when combined with pure oxygen, producing the hottest flame of any commonly used fuel gas. This extreme temperature makes acetylene the go-to choice for welding, cutting, and metalworking applications where you need serious heat concentrated in a precise location. The flame temperature drops to around 2,400°C (4,350°F) when acetylene …

Is Neon a Noble Gas?

Yes, neon is a noble gas. Why Is Neon a Noble Gas? Neon is a noble gas because its outer electron shell is completely full, giving it zero chemical motivation to bond with other elements. Its electron configuration is 1s²2s²2p⁶, meaning all 10 electrons are locked into stable, filled orbitals. This is what chemists call …

What Is Ethylene Used For?

Ethylene (C₂H₄) is used for plastics and packaging production, commercial fruit ripening, medical device sterilization (as ethylene oxide), antifreeze and coolants, PVC manufacturing, detergents and surfactants, polyester fibers, low-temperature refrigeration, and welding fuel gas, among other industrial applications. WestAir supplies ethylene across California and Arizona. Why Is Ethylene Such a Big Deal? Global ethylene production …

Why Are Noble Gases Unreactive?

Noble gases are unreactive because their electron shells are completely full, so they have no reason to bond with other atoms. Every chemical reaction happens because atoms want to achieve a stable electron configuration, but noble gases already have it. Think of electrons like seats on a bus. Most elements have empty seats or too …

What CO₂ Level Is Dangerous?

CO₂ is considered dangerous at 5,000 ppm (0.5%), which is OSHA’s 8-hour exposure limit and the point where safety alarms are set to trigger. But there’s more to the story. Continue reading to learn all about CO2 levels – and how to stay safe. What Makes 5,000 ppm the Magic Number? OSHA picked 5,000 ppm …

How to Choose an Industrial Gas Supplier

The wrong industrial gas supplier will cost you thousands (or more!) in runouts, hidden cylinder charges, and production delays. You should evaluate suppliers on delivery capabilities, cylinder tracking systems, service quality, and specialized needs rather than price alone. Avoid Running Out of Gas (and Get Fast Delivery if You Do!) To maintain continuous access to …

Does Nitrogen Displace Oxygen?

Yes, nitrogen displaces oxygen. In confined spaces, oxygen can drop from safe levels to deadly levels in minutes. In this article, you will learn: How Does Nitrogen Displace Oxygen in Confined Spaces? Nitrogen displaces oxygen by accumulating in confined spaces where poor ventilation prevents normal air mixing, creating pockets with dangerously low oxygen levels. Nitrogen …

Can You Weld with Nitrogen?

No, you cannot weld carbon steel, aluminum, or stainless steel with pure nitrogen because it causes severe porosity, arc instability, and brittle welds. The only exception is copper and certain copper alloys, where nitrogen provides adequate shielding. While nitrogen fails as a primary shielding gas, it has specific uses in welding operations including back purging …
