The linked company appears to be able to handle this. Although there aren't that many installations of their system. (Which is probably due to the system not yet reaching break even soon if at all, because energy is still quite cheap.)
As soon as an ammonia fuel cell is available as mature tech, ammonia will probably be the storage of choice for large scale systems.
But for residential storage hydrogen has the advantage that an electrolyser is comparatively simple mature tech, while ammonia synthesis probably won't be soon if ever.
- Schroedingersat 4y agoI can't find any price or performance numbers on their site so I'm sceptical. I did find some alibaba listings for pressure tanks. The cheapest believable ones were about $100 for a 50L 300bar tank. This works out to about $3k for a MWh of storage. You'd have to fill and empty it a couple of times a year for 20 years to break even vs nuclear just on the storage cost. It might beat retail in some areas though, and you'd need 50 or so of them to over winter in cold areas. Sounds like medium term storage (weeks) is solved if $100/tank (or even $1000/tank) is doable though.
