A Renewable Energy network consists of many parts, and this diagram gives a short overview over what the individual parts can do well, and what they cannot do.

~~“Batteries” is a rather broad category.
Are we talking hydroelectric batteries? Other potential or kinetic batteries? Chemical batteries (and what subcategory)? Or maybe hydrogen-based power storages?
Since there’s a dam on the list, I’d imagine “batteries” to be electrolytic power stores or hydrogen fuel cells, but the visualization remains lazy and perhaps borderline misinformative (depending on how nit-picky you are).
EDIT: The illustration might also use a simplified definition of a battery (to store, excluding conversion between kinds of power) instead of the different battery technologies which exist or the full definition, which could have one argue that batteries aren’t renewable by definition.
Though, that might be reading too much into it.~~
Actually, never mind, I’m probably too tired to go out on an adventure about the technicalities of the definition of “battery” to make any real amount of sense and not fall into edge cases.
I think you’re reading into it correctly. It’s an inaccurate depiction. The hydro line is what makes it fuzzy. A dam is a source but has no storage. A reservoir is not a source but has storage. They are separate devices meaning this needs two separate lines for hydro.
I imagine biomass is exactly the same situation, but I have no idea what OP is trying to use. Maybe I’m just uneducated, but it doesn’t sound like common knowledge. Still my assumption would be that there’s a source system to grow/maintain biomass and a separate system to extract that energy.
If those two items stayed as-is, then I can strap a battery directly to wind or solar and give them green check marks in both categories.
My idea is that most Hydro-Power plants can be used as reservoirs with little modification.
And biomass can be burned at whatever moment you like (provided you have the plants to do so), so it is “on-demand power” in some sense.
A fuel cell isn’t a battery, the process has more in common with a combustion engine than anything else.
