America has a new steel company, which is sort of a weird thing to write in 2025.

It’s called Hertha Metals, and it’s based in Houston. It’s also run by a woman named Laureen Meroueh, who is this week’s guest. As far as we can tell, Meroueh stands out as the first female to start and run a steel producer.

Meroueh grew up as something of a child prodigy in Florida and went on to earn a PhD in mechanical engineering from MIT. She then invented some of the processes that make Hertha different from traditional steel producers.

Hertha relies on natural gas and hydrogen instead of coal to make high-grade steel. Its process is potentially cleaner, simpler and cheaper than the approaches used by the traditional steelmakers that have been around for more than 150 years. The start-up is already producing one ton of steel per day and is now looking to prove that it can make much, much more and compete head-to-head against the major steel players.

In this episode, we get into how Hertha’s process works, the steel industry overall, why the U.S. needs this type of technology and how Meroueh ended up as a steel magnate.
