Germany could deploy 10 million heat pumps by 2030
The study demonstrates that a strategic, cost-effective expansion of decentralized heat pumps in Germany relies heavily on integrating photovoltaic (PV) generation and buffer heat storage. By modeling various rollout scenarios, researchers concluded that investing in solar capacity alongside heat pumps not only supports the transition to renewable heating but also yields significant annual savings by reducing reliance on expensive natural gas. The analysis confirms that flexible heat pump systems, paired with appropriate storage, offer a least-cost pathway for decarbonizing the heating sector while stabilizing the electricity grid. Relevance to open data lies in the methodological transparency provided by the study’s foundation. The researchers utilized the open-source TEASER model to simulate hourly variability in renewable generation and heat demand, accounting for complex factors like electric vehicle loads and green hydrogen production. This use of open-source tools allows other scientists and policymakers to replicate the scenarios, verify the findings, and adapt the model for different regions or conditions, thereby fostering a collaborative and transparent approach to energy planning. The implications suggest that policy decisions regarding the speed of heat pump adoption directly impact infrastructure needs and economic outcomes. A faster rollout significantly increases the need for PV capacity but generates substantial savings, whereas incorporating heat storage reduces the required investment in both solar and battery storage. These insights highlight the critical importance of flexible heating solutions in managing the interdependencies between the power and heating sectors, offering a data-driven framework for optimizing future energy investments.
