For shorter periods, this can be mitigated by local heat storage. You can store 3 days worth of heat in two large insulated pallet tanks filled with water and a heat exchanger. This will also allow owners of heat pumps to draw power when it is cheaper.
The source is unfortunately both pay-walled and in Danish, but this engineer has built a cheap system that is on the way to getting commercialized. I'm definitely going to invest in it for my heat pump, as he claims it pays for itself in just 3-5 years: https://ing.dk/artikel/genbrugsplast-viden-vand-ingenioer-paa-vej-med-billig-loesning-varmelager-264208 https://ing.dk/artikel/genbrugsplast-viden-vand-ingenioer-pa...

- eternityforest 4y agoSmaller spaces will need less. And very small spaces might need a low enough amount that you can afford phase change material and save even more space.
