“…Beginning with heat production, we observe conflict between an electricity-and a gas-based trajectory of transition in district heating and in local supply. Current decarbonization strategies for heat generation in the European Union and in Germany either focus on electrification (via heat pumps; Abbasi et al, 2021;Kicherer et al, 2021) or green gases (Jensen et al, 2020;Ruhnau et al, 2019). Since both options are associated with conflicting business interests, different networks of actors try to advance their favored technological trajectory, which has substantial implications for the distribution of benefits and burdens.…”

Urban Heat Transition in Berlin: Corporate Strategies, Political Conflicts, and Just Solutions

In the field of urban climate policy, heat production and demand are key sectors for achieving a sustainable city. Heat production has to shift from fossil to renewable energies, and the heat demand of most buildings has to be reduced significantly via building retrofits. However, analyses of heat transition still lack its contextualization within entangled urban politico-economic processes and materialities and require critical socio-theoretical examination. Asking about the embeddedness of heat transition within social relations and its implications for social justice issues, this article discusses the challenges and opportunities of heat transition, taking Berlin as an example. It uses an urban political ecology perspective to analyze the materialities of Berlin’s heating-housing nexus, its politico-economic context, implications for relations of inequality and power, and its contested strategies. The empirical analysis identifies major disputes about the future trajectory of heat production and about the distribution of retrofit costs. Using our conceptual approach, we discuss these empirical findings against the idea of a more just heat transition. For this purpose, we discuss three policy proposals regarding cost distribution, urban heat planning, and remunicipalization of heat utilities. We argue that this conceptual approach provides huge benefits for debates around heat transition and, more generally, energy justice and just transitions.

“…Next, while some studies describe phasing out oil or ICEs in the transport sector as a substitution exercise, others frame this as part of a broader signalling strategy aimed at catalysing the transformation of the entire automaking industry (Meckling and Nahm 2019). Meanwhile, in the illustrative case of district heating in Hamburg in Germany, the phase-out of fossil fuels is framed as the lynchpin of a 'transformation path' towards so-called 'fourth-generation' systems, which rely on renewables, lower temperatures and smart controls (Kicherer et al 2021).…”

‘Phase-out’ is increasingly mobilised in research and policymaking as an approach to catalyse the gradual decline of technologies, substances and practices that compromise environmental sustainability objectives. This trend is particularly pronounced in the context of climate change, demonstrated by the accumulation of a vast body of scholarship over multiple decades. Our work provides the first systematic review of the state of this knowledge, mapping out how phase-out is studied and employed as a policy tool for mitigating climate change. We systematically review over 400 publications, spanning three decades (1990-2021) and diverse scientific fields. Our review asks: How has scholarly work discussed phase-out as an approach to mitigate climate change, and how has this changed over time? We tackle this question from five perspectives: (i) elements targeted by phase-outs, (ii) policy instruments, (iii) affected industries, (iv) geographic context, and (v) benefits besides climate change mitigation. Results reveal that phase-out has widely proliferated as a decarbonisation approach, developing into a bridging concept that links diverse communities of contemporary science and practice. This is reflected by engagement with manifold phase-out targets – stretching well beyond the usual suspects related to fossil fuels and end-use technologies – as well as discussion of a growing diversity of industries, policy instruments and geographies in the literature. This global proliferation of phase-outs is propelled by expectations of diverse co-benefits. Aside from gains for the environment, economy, society and health, we find widespread acknowledgment that phase-out can drive innovation and systemic change beyond mere substitution. Our study also identifies several underdeveloped and underrepresented directions meriting further study. These notably include phase-out activity beyond Europe, North America and China, hard-to-abate industry sectors and non-fossil fuel targets. We conclude by carving out broader implications for scholars and practitioners to inform future research directions and climate mitigation efforts.

“…Existing research showed that a high quality heat atlas, which contains the geospatial representation of heating and cooling demand and potential supply, is an essential prerequisite for DH planning [14]. The lacking of such a high quality heat atlas was shown to be the bottleneck for the development of some technologies and for local strategic heat plannings [15,16]. In the present work, practical information will be provided as a first step towards the establishment of such a heat atlas.…”

Optimal Planning of Future District Heating Systems—A Review

2022

View full text Add to dashboard Cite

This article provides the state-of-the-art on the optimal planning and design of future district heating (DH) systems. The purpose is to provide practical information of first-step actions for countries with a low DH market share for heating and cooling supply. Previous research showed that for those countries, establishing a heat atlas with accurate geographical data is an essential prerequisite to promote the development of DH systems. In this review, essential techniques for building a high-quality heat atlas are elaborated. This includes a review of methodologies for district thermal energy demand prediction and the status of the integration of sustainable resources in DH systems. In the meanwhile, technical barriers for the implementation of various sustainable heat sources are identified. Furthermore, technologies for the optimal planning of DH systems are discussed. This includes the review of current approaches for the optimal planning of DH systems, discussions on various novel configurations which have been actively investigated recently, and common upgrading measures for existing DH systems.
