    I’m sure batteries will play an important role in the future, but it’s not significant today and I don’t see any indication of this changing rapidly in a meaningful way. I’d love to be wrong though.

    Regarding the issues with nuclear power, the ecological impact is far better than hydro and health impact/deaths is also significantly better. I’m not trying to badmouth hydro here, but I think it’s important to be fair and acknowledge that on those two issues (ecological impact, human health) nuclear has a better track record.

      Even in US, $100/kwh retail battery price points with bms, 48v, exist. Utility scale in rest of world is much cheaper. China is $51/kwh for a containerized full battery solution with (4 hour) inverter. At 7% ROI (to pay for full 30 year mortgage on LFP batteries as that is their life expectancy at slow charge/discharge rates) means just 1c/kwh discharge profit is required to pay for $55/kwh batteries. Similar calculation for just 4 sun hours/day. $600/kw installation costs at 7% ROI, means 3c/kwh daytime electricity rates.

      There’s not just exponential growth as @Hellgruen@lemmy.zip pointed out, it is dumb to do anything else.

        Ok man good luck with that. Since the economy is so overwhelmingly in your favor, we should see battery capacity outpace energy need growth any time now.

          Not sure if you are actually pretending its out of reach. China’s battery additions including EVs is 39% of massive electricity production increases. Rate of growth in battery sales about double while energy growth is 5-8% range. That is much easier for any country that isn’t the absolute global manufacturing nexus.

          For context, that’s growth, not total capacity. And after covid one would suspect ppl would understand exponential growth and to understand what that means for a business Modell $$$

          Also we don’t need capacity for the whole output of a year.

            For even more context, the annual growth in electricity output is about 5x the addition of battery capacity.

              That doesn’t change the fact that battery storage is a business case with exponential growth and is just taking off while nuclear power is expensive, takes long time to plan and build and all the new fancy stuff is still hypothetical and it’s not certain it will ever take off in regard of recent bankruptcy’s in the smr field

        Yes, like those. Your three examples show how benign nuclear power is, factoting in the absolute worst of circumstances and most ridiculous levels of incompetence.

            Maybe you should do your own homework before linking Wikipedia at me. Nuclear is safer than hydro in terms of human casualties per energy produced as well as per land mass destroyed, and if you want to make a counter-argument or add any other variable the burden of proof is on you.
