It's that time again on a Friday when Update At Noon presents another Update From The Coal-Face with Martin Creamer, publishing editor of Engineering News and Mining Weekly.

1. South Africa's Mintek this week shot ahead of the world by using hydrogen to process ferromanganese.

2. Bulgaria this week reached out to South Africa to collaboratively perfect the generation of green hydrogen.

3. Storing hydrogen is the best way to store energy, a top German research company pointed out this week. 

Martin Creamer will be back at the Coal-Face at the same time next Friday.
