High-temperature heat pumps: Fundamentals, modelling approaches and applications
In March 2023, the European Parliament and Council reached a consensus to increRCiase the binding renewable energy target (RES) to a minimum of 42.5% by 2030, effectively doubling the proportion of RES from the 2020 baseline. This significant development aligns the EU more closely with the objectives of the European Green Deal and the REPowerEU ...
