If we look at the battery storage projects highlighted in today's daily report and in the Exhibit below and then read some of the raw material inflationary concerns around batteries, we conclude that batteries will likely not end up dominating the power storage market. Both hydrogen and hydraulic-based storage are likely to be competitive if the battery costs do not come down. Note that storage batteries can afford to compromise on technology as they do not need leading-edge density – weight is not an issue for something that is not going to move. Even so, with battery demand expected to grow rapidly for EVs, it is not hard to see a scenario where other means of fixed location energy storage are more attractive.
