Reaching net-zero GHG emission targets will require transitions in all socio-technical systems, including electricity, mobility, heating, and agri-food. While most research focuses on single it is essential to also investigate multi-system interactions since innovations like electric vehicles, heat pumps, or circular economy initiatives between multiple systems. Although extant acknowledges this topic some extent, offers limited understandings of the causal processes underpinning interaction. Building sustainability literature, paper therefore aims develop a first inventory transitions, focused technological, actor, institutional dimensions. To elaborate substantiate contribution, applies narrative review methodology identify six based integration insights from relevant social science theories with dynamics approach Multi-level Perspective. We illustrate examples transition articulate their implications for speed change.

Multi-system interactions in hydrogen-based sector coupling projects: System entanglers as key actors

Energy Research & Social Science, Год журнала: 2023, Номер 105, С. 103282 - 103282

In advanced transition processes sector coupling becomes key to reach net zero objectives. The literature on multi-system interactions addresses the of different systems by analysing how technologies, institutions, and actors connect. Our contribution zooms in better understanding concrete activities characteristics who work integrate systems. It is crucial understand realise integration sectors as represents a major bottleneck accelerating processes. To identify their activities, we build recently established concept work, which adapts institutional framework for use analysis link it 'system entanglers'. System entanglers are connect Empirically, apply our conceptual three qualitative case studies hydrogen-based projects within mobility, heating, industry Germany. We find that system cross-sectoral competencies learning, well fostering between-system links, further discuss sectoral context, constellation projects, self-perception respective matter.

The role of material resources for rapid technology diffusion in net-zero transitions: Insights from EV lithium-ion battery Technological Innovation System in China

Technological Forecasting and Social Change, Год журнала: 2023, Номер 200, С. 123141 - 123141

Опубликована: Дек. 30, 2023

A key challenge to achieving a net-zero transition by mid-century is rapid diffusion of several low-carbon technologies which requires massive upscaling production capacity including vast use material resources. However, both theory and main studies frameworks pay insufficient attention the role To better understand relationships between diffusion, production, in technology transitions, we conceptually elaborate resources value chain perspective on Technological Innovation Systems (TIS). We account for how scarcity appears it influences TIS structural functional dynamics with particular actors along respond. Our study China's Electric Vehicle lithium-ion battery shows that shortage critical materials occurred due tensions sectoral regimes influenced within across sectors. The contributes new insights circular chains, growth phase unfolds, urgency geopolitics influence diffusion.

(Un)usual advocacy coalitions in a multi-system setting: the case of hydrogen in Germany

Policy Sciences, Год журнала: 2024, Номер 57(3), С. 567 - 597

Опубликована: Авг. 12, 2024

Abstract Grand sustainability challenges span multiple sectors and fields of policymaking. Novel technologies that respond to these may trigger the emergence new policy subsystems at intersection established sectors. We develop a framework addresses complexities ‘multi-system settings.’ Empirically, we explore belief coalition formation in nascent subsystem around hydrogen Germany, which emerges electricity, transport, heating, industry is characterised by broad range actors from different sectoral backgrounds. find two coalitions: rather unusual industry, NGOs, research institutes as well an expectable gas heat sector actors. Actors disagree over production, application, import standards for hydrogen. However, there widespread support strong role state across almost all explain our findings combining insights advocacy politics transitions: Belief are influenced backgrounds actors, technology characteristics, trust former contacts. Our study contributes better understanding early stages multi-system setting.

Carboxylic Acid Enhanced Nano Zero-Valent Iron for Electrocatalytic Nitrate Reduction to Ammonia

Опубликована: Янв. 1, 2025

Ammonia (NH3), a widely used chemical product, has various applications in numerous fields. However, the high energy consumption of traditional ammonia synthesis process is inconsistent with pursuit "zero carbon," and there an urgent need for new method to synthesize NH3. The electrocatalytic NO3–-to-NH3 (NITRR) offers ideal route synthesizing NH3 under ambient conditions. Nano zero-valent iron (nZVI) been nitrate wastewater treatment due its environmental friendliness, low cost, activity. nZVI difficult recover prone deactivation because tendency corrode agglomerate. Here, we report enhance activity stability through carboxylic acid modification. In this study, oxalic citric modified on foam nickel substrates (OA-nZVI/NF, CA-nZVI/NF) were examined as examples. Experiments confirmed that Faraday efficiency (FENH3) from OA-nZVI/NF CA-nZVI/NF was 84.9% 91.47%, respectively, at −0.4 V vs. RHE, which significantly higher than nZVI/NF (64.5%). More importantly, FENH3 electrodes did not decrease after continuous electrolysis 100 hours. Subsequently, electrochemical characterization control experiments revealed modification reduced corrosion potential promoted generation hydrogen-free radicals (H*) nZVI/NF. This work provides economical feasible approach improving corrosion-prone deactivated materials.
