It's from 2013! 8 years later 2021 the progress would be exponential

Of particular note to you in the article:

To confirm that that the 10-nm silicon-water reaction generates hydrogen with no byproducts that could interfere with applications, the researchers used the silicon-generated hydrogen to operate a fuel cell. The fuel cell performed very well, producing more current and voltage than the theoretical amount of pure hydrogen, which is due to the fact that the 10-nm particles generated more hydrogen than the theoretical 14 wt %.

The magic ingredient nano silicon is generating more energy than theoretically thought possible. 

14% was in 2013. Imagine EBH2 with scientists who devoted their lives studying Hydrogen how high they have gotten that number and how optimized the system and materials have become.
