GreenRoc has commissioned a graphite pilot plant in Hørsholm, Denmark, focusing on the production of battery-grade active anode material. The facility currently operates a mechanical shaping circuit to convert natural flake graphite into spherical particles, a critical step for lithium-ion battery efficiency. To avoid the environmental and safety risks associated with hydrofluoric acid, the project is developing a sodium hydroxide purification route. This approach aims to meet EU sustainability standards while reducing the reliance on Asian supply chains for critical battery minerals.

GreenRoc is setting up a pilot plant in Denmark to turn graphite into battery anodes. They are trying to move processing to Europe to avoid relying on China for the whole supply chain. It is a small scale operation for now, but the goal is to prove they can make battery-grade material locally.

100kg per day is a tiny footprint. It is fine for a lab, but the jump from this to commercial scale is where most of these projects fail. I wonder what the actual power requirements for the full scale plant will be and if the local grid in Hørsholm can handle that kind of industrial load.

The move to sodium hydroxide instead of hydrofluoric acid is the real story here. EU chemical regulations make HF a nightmare for permitting. If they can actually hit 99.95 percent purity without it, they solve a massive regulatory hurdle for scaling in Europe.

NaOH is safer, but is it as cheap? Usually, these alternative chemistries come with higher operational costs or longer processing times. I would like to see the cost per tonne compared to the standard Chinese HF process before calling this a win.
