How can Germany go ahead with price caps on gas if the EU hasn't agreed to join in?

When the consumer price is capped the price that consumers pay doesn't have a direct relationship with the prices that distributors pay to the producers and importers. In the UK and Norway the state negotiates a deal with the producers and distributors to subsidise the price to consumers. I imagine that something similar is happening in Germany.

Maybe Germany has figured a way out of this global system of greed.
