 which gives us hydrogen, and we pull nitrogen from the air that we combine together to form anhydrous ammonia, which is the same nitrogen fertilizer that farmers use across the Midwest. There are other opportunities to further process that into urea by capturing CO2 from, for example, from corn fermentation from ethanol plants, and so that's another piece of it that's attracted to farmers. Where do you see this type of fertilizer production going in the future?
