Competition in Building Heating—The Techno-Economic Case for Decentralized Heat Pumps in Germany up to 2045

Şirin Alibaş, Songmin Yu, Stella Oberle, Anna Billerbeck et autres

Decarbonizing the German building sector by 2045 requires a rapid transformation of the heating technology stock, in which decentralized heat pumps (HPs) compete with district heating (DH) and green-gas-based solutions. Yet, the existing literature has not sufficiently resolved which segments of the …

Exploring the tabular foundation model TabPFN for performance map prediction of variable-speed heat pumps and compressors

Sahil Vishram Vadadkar, Beatrice Rodenbücher, Michael Kropp, Katharina Morawietz et autres

Conventional approaches to accurate modelling of heat pumps and compressors are predicated on the availability of high-fidelity, data-intensive models for each component. Statistical and machine learning (ML)-based approaches are often-used, well-performing simplification pathways for purely physics-based modelling. TabPFN, a prior-data-fitted tabular foundation …

Quantifying the impact of improved heat pumps in Germany's residential sector: A simulation-based scenario analysis

Karim Yassin, Sahil Vishram Vadadkar, Beatrice Rodenbücher, Hannes Fugmann et autres

The electrification of residential heating through heat pumps is a central pillar of energy transition strategies. While numerous studies assess the system-level implications of large-scale heat pump deployment, heat pump performance is typically represented using static or averaged current efficiency assumptions. At …

Quantifying battery stress factors: An intuitive generic model for calendar and cycle aging simulation using time series analysis

Samira Kiefer, Maximilian Bruch, Hans‐Martin Henning, Magdalena Graczyk‐Zając et autres

This study introduces a comprehensive and generic aging model that disentangles and quantifies the isolated effects of individual stress factors on lithium-ion battery degradation. Unlike traditional empirical or semi-empirical models, which often combine stress factors into aggregate predictions, the proposed framework leverages …

Direct and indirect electrification in the German industry from a sector-coupled energy system modeling perspective

Markus Kaiser, Charlotte Senkpiel, Hans‐Martin Henning, Christoph Kost

To achieve greenhouse gas (GHG) neutrality, a shift from fossil fuels to GHG-neutral energy sources is essential in the industrial sector. Direct and indirect electrification are the primary strategies for this fuel switch. This study uses four normative target scenarios to derive …

Closing the ambition gap: Germany's energy transition in line with a 1.5ˆC carbon budget

Patrick Jürgens, Markus Kaiser, Charlotte Senkpiel, Connor Thelen et autres

To limit global warming to 1.5∘C, rapid and significant reductions in greenhouse gas emissions are essential. However, there is a lack of analyses considering transition pathways using sector-coupled energy system models that limit national emissions to a 1.5∘C per capita carbon budget. …

Enhancing heat pump performance for domestic hot water preparation: A comparative analysis in existing multi-family houses

Michael Kropp, Manuel Lämmle, Sebastian Herkel, Hans‐Martin Henning et autres

The building sector is accountable for roughly one third of global energy- and process-related greenhouse gas emissions. Besides space heating, domestic hot water (DHW) heating contributes substantially to energy consumption and related greenhouse gas emissions in the building sector. Depending on the …

Increasing spatial resolution of a sector-coupled long-term energy system model: The case of the German states

Julian Brandes, Patrick Jürgens, Markus Kaiser, Christoph Kost et autres

A current challenge in energy system modelling is integrating high temporal and spatial resolution with a detailed representation of technologies and sector coupling within a single model. This paper presents a pioneering sectoral optimisation approach for transformation pathways in the German federal …
