3. Energy storage-as-infrastructure - creating an asset class for the 'workhorse' of the grid
We’ve heard all about energy storage as-a-service, primarily in the commercial space, where batteries are used to help business customers cut their running costs, or to enable more renewable energy use onsite.
For the really big stuff, it doesn’t make sense to work on merchant opportunities, or multiple contracted revenues: echoing the thoughts of many that we heard from at the Solar & Storage Live show in Birmingham, England last week, better recognition of the role energy storage could play as an infrastructure asset could be key to unlocking not just the whole benefit and usefulness of energy storage, but also unlock investment in the technology as an asset class.
Andy Tang at Wartsila told Energy-Storage.news at the Salt lake City show that the key to doing that in the US is to encourage and enable more and more utilities to consider energy storage in their long-term resource planning. That’s already starting to happen, but as we heard on a panel hosted by NREL, transparency, quality of data and proactive planning to capitalise on the benefits of distributed energy resources (DER) are also vital assistance that the industry can bring to the table.
Longer-term planning also potentially means more long-duration energy storage projects could be invested in. Proponents of vanadium flow batteries, for example, would argue that without degradation in the battery stack after even decades of use, it will be easier for investments to be justified to ratepayers and financiers alike, while the show was awash with numerous long-duration storage providers. In terms of which chemistries folks pointed out as promising, most said just one word: zinc.
