The Eur77-94 figure is a simulated average whole grid cost of electricity for a hypothetical grid built around renewables and storage only when including some of this type of storage, not the cost of this type of storage. They estimate LCOS for this storage at Eur309-366/MWh according to the article in Joule which is linked. I couldn't immediately see their estimates for cost of wind/solar and other types of storage which feed into the whole grid cost.
