HOT|COOL NO. 2/2023 "AI & Digitalization"

1.3 The boundary conditions of DH companies 2050 The countries studied in the project are at different levels of maturity where; both Denmark and Sweden

the upcoming years. Therefore, the project team en- gaged in several validation sessions with DH practi- tioners and mixed groups to gain feedback on iden- tified results.

5. Circular economy and, as a result of circulari- ty, coupled sectors Assumption: it is standard to work with circular flows to reduce the waste of any resource. As a consequence of circularity being the domi- nant driver in the economy. 6. Investors in energy are diverse Assumption: energy is a sector that has experi- enced a considerable transition period for sev- eral decades (2020ies-2030ies-2040ies). The in- vestments have been forced to be sustainable (economic-environmental-social), which has become standard. The transition has fostered entrepreneurship and many possible invest- ment projects attracting a diverse set of inves- tors. 7. A high level of digitalization is standard Assumption: Significant progress is expected. Using available data, algorithms, and integra- tion across systems will support energy effi- ciency, improved flexibility and control, and stronger and automated consumer activation.

1. The heat demand is at similar levels as in 2020 on an overall EU level, and cooling demand is higher than in 2020 Assumption: adding the energy efficiency and the densification, the heat demand is assumed to be at similar levels as in 2020 2. Heat supply is completely decarbonized, and it is standard to recover waste heat of both high and low temperature Assumption: it is foreseen that the combustion of fossil fuels is no longer possible. Combined with increased circularity, the volumes of waste for incineration are lower. This means that oth- er heat sources are needed where waste heat is important. 3. Heat supply is decentralized and combined with storage solutions Assumption: the focus on large, centralized production and distribution has been replaced by an emphasis on using available heat sources (of varying sizes). Heat is provided on demand when the customer wants it. Therefore, the ability to store heat is increasingly essential. 4. Heat planning is mandatory at a municipal level Assumption: it is standard for municipalities to have energy plans per sector where heating and cooling is one.
