A Danish convenience store covered 100% of its heating demand from refrigeration waste heat — through the coldest winter in over a decade, and exported the surplus to the city grid.
This issue looks at what happens after the refrigerant decision is made: how CO₂ systems perform once installed, and how much of their potential as an energy hub holds up in real operation.
