The overwhelming majority of utility scale storage will not be in batteries, so battery technology does not matter.
The sun does, in fact, shine far, far more than enough.
- TheSpiceIsLife 4y agoOk, I'll bite. What type of utility scale storage isn't a battery? The answer is, of course: any energy storage setup is a battery[1]. A more generous interpretation of your comment is that you meant won't be chemical batteries. In which case, I'll bite: what then? 1. Energy storage is the capture of energy produced at one time for use at a later time[1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. https://en.m.wikipedia.org/wiki/Energy_storage https://en.m.wikipedia.org/wiki/Energy_storage
- Gwypaas 4y agoSweden generates 40% of the current power generation from hydro. Adapt that to be more flexible than baseload and Sweden has amazing capabilities to run an entire renewable grid mainly based on wind with a minimal amount of chemical short-term storage. There are few countries with better opportunities for renewables than Sweden.
- sandos 4y agoWe are in a good place, but our hydro is basically maxed out and can not support a future (with higher consumption) no-wind scenario during winter since it does not have enough power for that alone. Nuclear power is a good idea, but so is wind for Sweden. We already have a lot of wind but high pressure areas with little wind do exist, even in winter. Nuclear looks kind of good from that point of view, but I strongly feel that Sweden is way too small of an actor to buy reactors on her own, and should actually co-order reactors with other countries, getting the costs down (maybe not even costs, but risks. There have been a lots of bankrupted players in nuclear lately).
- heartbreak 4y agoIn the US we have utility scale pumped storage hydro power which is a non-chemical battery (assuming you’re referring to chemicals other than water).
- TheSpiceIsLife 4y agoPumped hydro only works in certain locations, almost all of which are already used, and any that remain are at the whim of environmental approval.
- tored 4y agoHydrogen. However electrolysis is still an immature technology and has massive energy losses in every step of the procedure. You can negate that somewhat if produce and store at the same location of the intended use, like providing electricity to a building with hydrogen tank, hydrogen that is generated by solar panels. However this is of course not enough to run industries with high electricity demand, what people tend to forget is that one factory (like melting of aluminum) can consume more electricity in one day than an entire city in a year. For that you need nuclear power or hydro.
- ncmncm 4y agoHydrolysis has had high losses until recently, but efficiency is now well over 90%. The remaining problem is building factories for electrolysis equipment. Building factories takes an appallingly long time. But the problem is only of time, not technical maturity.
- beefield 4y agoAs we are talking about Sweden, a relatively cold country, a big chunk of energy consumption is about heating. And heat is a form of energy that is much easier to storage than electricity. I very much assume that even seasonal storage of heat is becoming a big thing in coming years, dwarfing any chemical battery capacity whatsoever. After all, for that, in the most basic form, you need a big enough pool of water connected to electric grid with a resistor and to district heating system with a heat exchanger.
- doikor 4y ago> The sun does, in fact, shine far, far more than enough. Not in northern Europe. For example at the southern most point of Finland there is 3 months in the year when solar produces less than 1% of its name plate capacity. It does get slightly better in the southern part of Sweden but still not that great. Around Mediterranean is where solar starts to get really good though the Africa side of it is even better.
