Greeley Tribune- In 1956, Greeley resident Charlie Odendhal started working with a Shell Oil and Gas metallurgical team that focused on preventing hydrogen embrittlement in the field. In the process of drilling for oil and gas, hydrogen would get into the drill bits, causing them to break. Shell would just cap the hydrogen vents and move on with the operation. Today, 61 years later, Odendhal — along with a small team of international scientists — is on a mission to drill and capture that hydrogen Shell so easily dismissed. The hydrogen would be used to create ammonia, which would then be used to make fertilizer for farming.
