A misconception I often read on YouTube, Reddit, HackerNews is that everyone equates batteries with lithium ion batteries. A battery is a chemical storage device for energy and there are already many different types.
1. There are also functioning batteries without lithium, for example with salt, which are now already being tested in Swiss and German households and bring some advantages compared to lithium batteries. Not least the price. One should always remember that the lower energy density is a problem for an electric vehicle, but it doesn't matter if we install a battery in a cellar. Here, the energy density plays a subordinate role because there is enough space.
2. Would it make more sense to talk about *energy storage* in general instead of just batteries (which are by definition chemical energy storage) Kinetic, chemical, thermal and so on. Lithium ion batteries should not be considered for back-up alone. We definitely need more choices and we have them, mostly with today's technology and definitely easier and faster to develop and install than any new nuclear reactor technology.
3. You need different types of batteries short term storage, medium term storage and long term storage. There are different concepts for each use. Batteries, compressed air storage, pumped storage, thermal storage as well as power-to-x systems are able to absorb the increasing summer power from solar, autumn wind, etc. and make the energy available again in the short term, medium term or seasonally shifted.

4.The best approach, however, is to build a decentralised grid, which is also intercontinently connected. This is the perfect way to compensate for any "dark lulls". There is research on this at some universities around the world that is already out of laboratory status.
- Maakuth 3y agoVery good points. I do think the grid battery capacity being added this year is going to be mostly li-ion.
- Ringz 3y agoThats (sadly) true! I think the transition to a diverse heat and electricity storage landscape will take time. Citing from "Handbook Energy Storage SCCER" https://doi.org/10.3929/ethz-b-000445597 https://doi.org/10.3929/ethz-b-000445597: "The SCCER has proven in numerous demonstra- tions that storage technologies are essentially available and usable. Now it is necessary, above all, for political decisions to be taken in the inter- ests of a coherent energy policy in order to re- duce the regulatory obstacles that currently im- pede or make impossible the economical use of energy storage. This can guide business models and investment decisions necessary to advance the technologies developed in the SCCER and bring them from the laboratory into the ultimate energy system of the Energy Strategy 2050."

However, sb. tried to access this url in Nov 2021, but it did not exist back then aswell: https://web.archive.org/web/20240216101723/https://tu-dresden.de/tu-dresden/newsportal/news/meilenstein-in-der-energy-transition-scientists-at-the-tu-dresden-build-unique-energy-storage https://web.archive.org/web/20240216101723/https://tu-dresde...
- Ringz 3y agoYes this one: https://tu-dresden.de/tu-dresden/newsportal/news/meilenstein-in-der-energiewende-wissenschaftler-innen-der-tu-dresden-bauen-einzigartigen-energiespeicher https://tu-dresden.de/tu-dresden/newsportal/news/meilenstein... Many of my texts and links are from the years 2019-2022 when I was researching for various publications on renewable energy. Most of them, unfortunately, without DOI links. I didn't check them before I uploaded them here. And I would have so much more that it would be enough for an entire book.
- RugnirViking 3y agoin industry here in europe I usually see it written as ESS/BESS (energy storage system or battery energy storage system). For new plants we usually simulate each of five or six technologies, however in a lot of cases yes lithium ion has many advantages.
