Trona: Wyoming's Buried Treasure

Beneath southwest Wyoming lies the largest trona deposit on Earth. What is this mineral, how did an ancient lake create it, and why does it matter for both soda ash and hydrogen?

The Colors of Hydrogen

Hydrogen is colorless — but you will hear it called green, blue, grey, and more. The colors are a shorthand for how it is made, and they decide whether it actually helps the climate.

Will It Hold? The Geomechanics of Keeping a Cavern Stable

An underground cavern is a hole in rock that is squeezed, flows, and slowly closes. A visual look at the stress, creep, pressure limits, and subsidence that decide whether storage stays safe.

Anatomy of a Storage Cavern

What is actually down there? A guided tour of an operating hydrogen cavern — wellhead to sump — and the cushion gas, working gas, and pressure window that keep it running.

Solution Mining: Carving a Cavern from Rock

You cannot dig a cavern a kilometre underground — you dissolve one. A visual look at how water, circulation, and a clever floating blanket sculpt a storage cavern out of solid salt or trona.

Trona or Salt? Choosing the Rock That Holds Our Hydrogen

Salt caverns are the proven home for underground hydrogen — but Wyoming sits on something different. A visual tour of how trona stacks up against salt as host rock.
