Thats (sadly) true! I think the transition to a diverse heat and electricity storage landscape will take time. Citing from "Handbook Energy Storage SCCER" https://doi.org/10.3929/ethz-b-000445597:
"The SCCER has proven in numerous demonstra-
tions that storage technologies are essentially
available and usable. Now it is necessary, above
all, for political decisions to be taken in the inter-
ests of a coherent energy policy in order to re-
duce the regulatory obstacles that currently im-
pede or make impossible the economical use of
energy storage. This can guide business models
and investment decisions necessary to advance
the technologies developed in the SCCER and
bring them from the laboratory into the ultimate
energy system of the Energy Strategy 2050."
