Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

This is for Australia. Similar studies for Europe exist. The picture is very similar: combine wind and solar to match the annual load cycle and partly cancel synoptic variability; several-hours storage for part of solar to make it usable for night hours also; and build a modest overcapacity.

The only thing different in the Heide plan is the use of hydrogen storage (rather than biofuels/biogas) for synoptic time scale backup. Other storage options studied in Germany are syngas (methane) from spilled electricity which could be stored straight into the existing natural-gas infrastructure. Existing capacity would be several months!
