Current status of the H2 project is normal. Normal as for the last year. My technician/data guy is in hospital now, nothing to do with Covid but nevertheless 'out of the game' for a long while. I'm rebuilding the lab, switching over from a focus on process chemistry to analytical chemistry, and re-decorating re-arranging the physical layout too, but I'm working on my own currently as skilled technicians are a sellers market.
The reason for the shift in focus is that the process stuff is now established as solid. The quest now it working on the conversion of the 'technical grade' aluminium hydroxide (TGA) produced at 99.5/99.7 purity to 99.95+ purity, so-called High Purity Alumina, (HPA) for the hydroxide my process produces is sodium - free, which is a better starting point than Bayer-process hydroxide which contains high levels of residual Na as well as other impurities.
HPA is worth anything from 10 to 30 times as much as TGA and the market is predicted to grow by over 1200% by the end of this decade.
