Thanks for linking the real article. It's an interesting read, especially that the Gibb's Free Energy for formate-bicarbonate is so low. Ammonia is about 20-40x higher!

Looks like they're using Pd/Pt for the best catalyzers... that's definitely not going to be scalable. Though there should be effective alternatives, but it's surprising how unsophisticated much of the research in this field can be.
