Berlin-based climate research institute Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study indicating that, in the last decade, the cost of solar power has dropped by 87 percent, and the cost of battery storage by 85 percent.

Solar power and storage prices have dropped almost 90%::undefined

    Maybe raw battery cost has reduced but installed storage is 30% more expensive than it was a couple of years ago, and it was too expensive then…

      probably when using carbon cathodes instead of cobalt, the energy density drops from 300wh/kg to just 150wh/kg, so u would need extra anode/electrolyte mass to store the same amount of energy.i bet that those prices hikes are a result of diversion from rare earth metal mining…but just a guess
