If the approval process continues as it currently does and solar installations do not slow down massivly, by the end of the term the approved renewbales projects should bring Gemany above 80% renewables. Practically speaking that would be the coal exit done. Maybe not fully, but they would not matter much.

As for the rest, the current plan for hydrogen power plants is currently being negotiated with the EU. The good news it looks like a deal has been reached and if the plans shown by the current government are implemented, that would basicly mean a full coal exit and the starategic storage question being answered.

Basicly the current German government has passed laws for an estimated 64% redcution of emissions by 2030 compared to 1990. The current target is 65%. So with a bit of luck it will work out.
