Total installed battery storage capacity in Germany has now reached 10Gwh. Nearly 1 milion homes have battery storage systems installed.

  2. for scale

    * Germany consumed roughly 550 Twh of electricity in 2022,which is 1.5 Twh( 1500Gwh) a day
    * given that a day has 1440 minutes, all battery storage capacity in Germany can cover the **entire consumption of the country for roughly 10 minutes per day,if charged/discharged every day**

    more significant is however the battery capacity of electric cars curently in use in Germany

    at 1.2 million EVs on the road in July 2023, and asuming 50kwh battery capacity per EV, we get 60 Gwh of battery capacity

    **All passenger electric cars curently on the road in Germany have enough battery capacity to power the entire country for 1 hour**

    this is why i think electric cars have a huge potential to act as part-time grid storage ,with the right incentives

    ex: charging your car in the afternoon at work,while sun is shinning,and then using it to power your house at night,when sun is not shining

    or charging your car when electricity is cheap,and then selling some electricity back to the grid when electricity prices are very high

  5. Are electric car batteries counted as “home storage” here?

  6. it looks nice but when you think about how much it is its laughable

  7. It’s perhaps worth noting that batteries have rather high production emissions ([~200-250 gCO2eq/kWh](https://onlinelibrary.wiley.com/doi/10.1111/jiec.13344) over the entire lifecycle for residential batteries) and as such, cannot really be described as low carbon (it’s about twice better than a traditional fossil gas plant and ~on the same level as an optimized modern combined cycle gas plant).

    Improvements are needed in the manufacturing process and some are underway but it’s hard to see batteries as climate friendly.

  8. How many batteries can be produced and disposed of in a environmently friendly way? If the goal is to replace all fossil fuels with batteries, the world is going to need a metric shitton more.

    To put things in perspective; 1 liter diesel contains 10 kWh of energy (although a great deal of this is wasted in regular combustion engines).

  9. that’s great, expect that you burn coal to load them 😀

  11. What kind of batteries are those? Here in Portugal there’s a massive market for solar panels but battery packs aren’t really very widely available and really not worth the price.

    Tesla?

  12. I like exponential graphs. They always end in something big

  13. Now let’s do the Large-Scale next which was requested for a decade but never invested by state or country

  14. Wow that graph is totally insane….

    I’m starting to get more hope about the green revolution guys, it kind of the only dot of light in our tunnel, and it’s getting brighter.

    We might convince the rest of the world to get on the same track, we’ll reduce dependence on shitty countries and make sure they don’t earn anymore.

    Totally loving it
