O.2.2.1 Hybrid heat pumps minimize emissions and minimize overall costs

Heat pumps are more attractive than (many) conventional heating methods mainly due to their efficiency. A lot of research has been devoted to this merit. This paper describes the impact of heat pumps on the energy chain, not only in residential homes but specifically also on infrastructure and emissions.
Hybrid heat pumps offer specific advantages in a sense that the carrier can be varied depending on specific circumstances, thereby improving efficiency and reducing emissions with only limited impact on energy infrastructure costs. This is achieved through the following operations: Switching to gas where heat pump efficiency is poor reduces energy bills and also reduces electric peak load (reducing electricity infrastructure costs). At times when emission factors of electricity are poor, a switch can be made to gas as energy carrier. Switching to electricity during periods of abundant availability of clean electricity also reduces emissions. Switching to gas at very low outside temperatures avoids installing low-temperature radiators in existing homes and thereby reduces costs.
This research has been conducted by Gasunie in cooperation with partners.
