Hem... It's of course "cool" but... At scale of supermarkets fridges not lab specimens, especially in not-so-cold climate the needed energy to keep food cool off grid it's MASSIVE. Of course the future of a grid with most customers with local storage at least for 24h, local p.v. and negotiated charge from the grid (to help keeping the frequency, consume where there are more renewable than demand etc) is a probable one, but honestly a small refrigerated micro-fridge can't be compared, so the first part and the second part of the article are totally disconnected. The device itself might have some interesting applications but in terms of environmental limits, price, reliability I doubt it can became spread much.
