Explainer: Making the most of ammonia and urea as a green fuel

We've talked a lot about fuel on the show recently, including alternative options like hydrogen, and today we're going to look at ammonia and urea. It's primarily used here as a fertiliser, to increase crop yields and boost pasture growth for sheep and dairy, however there's also demand for it as a green fuel. The bulk of our ammonia and urea supplies come from the Middle East, but one Kiwi company is hoping to change that. Liquium is a new company spun out of Wellington University that is aiming to boost domestic production efficiency and unlock new ammonia export markets. Chief Executive Paul Geraghty joins Jesse.
