Is there any storage mechanism whose costs don't increase in the same way?
- the8472 7y agoAnything that involves volumes and abundant resources. E.g. storing hydrogen or compressed air in a salt dome decouples the power rating of your storage (MW) from the storage capacity (MWh). Similarly hydroelectric dams contain water by volume but you only need to dam a cross-section of the valley.
- jhayward 7y agoWouldn't the above description also fit flow batteries?
- the8472 7y agoIt's a little less clear-cut since you still need to pay a linear cost for the electrolyte, but it should be much lower than the same amount of Li-ion storage, at least in raw material costs.
- SECProto 7y ago> Similarly hydroelectric dams contain water by volume but you only need to dam a cross-section of the valley. I would caution that the cost of a dam does not increase linearly, either (and that most resources that are profitably dammable at utility scale have already been dammed)
