Hydro pump isn’t sci-fi. It’s been around for quite some years and has been proven to be quite successful.
Or maybe politicians and permitting agencies.
Long term storage is not needed. 8 hrs is more than enough. If you need power after 8 hrs then bring Emergency Gas Turbines online. They are cheap to build but expensive to run. But an emergency is an emergency.
The main problem with long duration storage is that once you have a battery, you would want to use it as often as possible. If you have the option of running a 1MWh storage twice a day (intra-day) or twice a year (from season to season), the long duration option would have to be 365 times more profitable per MWh for you to choose that option.
You would have to have to type of storage where additional capacity capex is insignificant compared to power capex.
Yes it is a problem. The article lacks solutions.
The classic paper is the Rocky Mountain Institute storage value chains. With energy storage, you have to pay for the charging energy. So you want to acquire that at a very low price out of market with a PPA. The most valuable is ancillary services, especially frequency response. But Wood MacKenzie has said that market saturates early. We don’t yet pay for inertia.
A big variable is how far in advance we can forecast wind generation and how dependent your resource mix is on wind. Predicting wind a week or three in advance can help long term energy storage – storage would know when to buy energy to store. But long term storage will have the same challenge of how many long term hours it is called for in a year, or in its lifetime.
Our current markets, even RTO/ISO Lite in the SE, are short term – real time/15 minutes ahead, and day-ahead/extended day-ahead. That gives an advantage to wind, because wind can always bid into the real time 15 minute market and it has low operating cost. Capacity markets are a very crude tool and the capacity fees are low.

That’s an old ass pic they’re using.
There are elections today vote accordingly.
