The energy sector is responsible for more than 75% of the EU’s greenhouse gas emissions. Increasing the share of renewable energy or avoiding wasting heat across the different sectors of the economy is therefore a key building block to reaching the goal of reducing the EU net greenhouse gas emissions by at least 55% by 2030 and becoming a climate-neutral continent by 2050. The revised Renewable Energy Directive EU/2023/2413 raises the EU’s binding renewable target for 2030 to a minimum of 42.5%, up from the previous 32% target, with the aspiration to reach 45%. Under these circumstances, the Heat Pump Technologies are considered a valuable solution to provide at the same time low primary energy consumption and large usage of renewable energy in all sectors: residential, commercial and industrial, including the use as heat source of waste heat coming for example as an undesired consequence of Industrial Processes or Data Centers heat rejection in atmosphere. Waste heat, instead of being discharged in atmosphere, can be efficiently used as a heat source by large industrial heat pumps, implementing new generations of heat recovery systems, such as those obtainable through the now mature HTHP (High Temperature Heat Pumps) & VHTHP (Very High Temperature Heat Pumps) applied to thermal waste to capture the so-called waste heat generated in industrial processes in favour of a large re-use in the industry or even more frequently re-used for heat contributions to the District Heating & Cooling networks for collective housing, cities and communities.
