Direct fired applications for DCC https://stockhouse.com/news/press-releases/2024/06/20/hydrogen-technologies-primed-for-expansion-beyond-steam
This looks really interesting. It appears their newest patented DCC burner can be used beyond the steam boiler for zero emission direct fire industrial uses. I am not sure how big the market opportunity is, but seems massive... steel, glass, cement, chemicals and lots more.
If they can license that burner tech out, could be huge. Check out the website of their partner Selas.com. They look very legit in the industry.
