A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to the country case of Jordan. It is designed to support the strategy development and to serve as a guide for decision-makers.
The analysis shows that Jordan has taken essential steps towards a RE transition. According to the MENA energy transition phase model, Jordan can be classified as being in a transitional stage between the first phase, "Take-Off Renewables", and the second phase, "System Integration". However, fossil fuels continue to play a dominant role in the Jordanian energy sector, and the fluctuating world market prices for fossil fuels impact the economy.
The expansion of domestically produced RE could significantly contribute to reducing Jordan's high imports of fossil fuels. This simultaneously increases energy security and reduces the trade deficit. To move towards a sustainable energy system, Jordan needs to embrace comprehensive flexibility measures. These include developing storage options, improving load management, upgrading the existing grid infrastructure, enhancing energy efficiency, exploring the electrification of end use sectors, and creating strong cooperation between stakeholders.
Um die Treibhausgasneutralität bis 2045 zu erreichen, wird unter anderem erforderlich sein, dass die Industrie klimaneutrale Produktionsweisen entwickelt und umsetzt. Damit einher gehen gesellschaftliche Aushandlungsprozesse darüber, welche neuen Technologien eingesetzt werden und welche Auswirkungen vor Ort akzeptiert werden. Das Ausmaß an Akzeptanz gegenüber Technologien oder Infrastrukturen beeinflusst neben anderen Faktoren die spezifische Ausgestaltung der Transformation. Mangelnde Akzeptanz kann die Entwicklung von Transformationspfaden verlangsamen oder gar verhindern, und zu Protesten, beispielsweise von lokalen Initiativen oder von etablierten Klimaschutz- und Umweltverbänden, führen.
Dieses Wuppertal Paper stellt die Frage in den Fokus, welchen Einfluss Protestbewegungen auf öffentliche Akzeptanz haben bzw. haben könnten. Grundlage dafür sind empirische Ergebnisse aus dem Projekt Protanz.NRW zu Protesten und Akzeptanz im Kontext der Industrietransformation in NRW. Darauf aufbauend wird ein Protest-Akzeptanz-Modell entwickelt und es werden Hypothesen abgeleitet, wie unterschiedliche Protestgruppen die öffentliche Akzeptanz von Technologien für die Industrietransformation in NRW beeinflussen können. Abschließend werden Handlungsempfehlungen für Politik und Industrie abgeleitet sowie Forschungsbedarfe aufgezeigt.
Reaching net-zero in the chemical industry : a study of roadmaps for industrial decarbonisation
(2024)
Striving to mitigate climate change, the European Union has adopted net-zero greenhouse gas emissions as a target for 2050. In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategies, investment needs and costs, agency and dependency on other actors, as well as timeline and concretion. Although net-zero pathways are often drawn out in the roadmaps, some also choose to emphasize and argue for less ambitious pathways with emission reductions of only 40-60 %. The roadmaps vary widely in terms of the importance they assign to mechanical and chemical recycling, switching to biogenic carbon and carbon dioxide as feedstock, electrification and hydrogen, and carbon capture and storage. A commonality though, is that low-tech or near-term mitigation pathways such as demand reduction, reuse or material efficiency are seldom included. High investment needs are generally highlighted, as well as the need for policy to create enabling conditions, whereas the agency and responsibility of the chemical industry itself is downplayed. Our analysis highlights that the chemical industry does not yet have a strong and shared vision for pathways to net-zero emissions. We conclude that such a future vision would benefit from taking a whole value chain approach including demand-side options and consideration of scope 3 emissions.
Case study on the German discourse of industry decarbonisation : a discourse network analysis
(2023)
The adoption of the Paris Agreement in 2015 and the passing of the Climate Action Law in Germany in 2019 established the legal need for the basic material industry in Germany to decarbonise. For the industry sector, the target is sets at a 49-51% GHG reduction by 2030 compared to 1990. Even though the sector specific targets are likely to become obsolete, a Hydrogen Strategy, Industry Strategy and Climate Protection Contracts are currently being developed or elaborated on. These are to further ensure and enable the basic material industry in Germany to decarbonise. These developments are emphasising the relevance of studying the industry decarbonisation at the time of conducting this research.
As the institutionalisation of the industry decarbonisation is influenced by discourse, the analysis of the discourse is an important tool for studying the power effects produced by and built into the discourse. This is the first research aiming to provide a structured analysis of the discourse on industry decarbonisation in Germany. Drawing on discourse analysis and the Multilevel-Perspectives framework, this research investigated the power and dominance of storylines to influence the discourse of the industry transformation towards decarbonisation. In this research insights were obtained into the storylines used in this discourse, the actors who are part of this discourse, the frequency of storylines used and the percentage of actors making use of these storylines. Additionally, insights were generated into the discursive network and potential coalitions.
This research made use of the Discourse Network Analysis software in combination with Visone and Excel for data collection, analysis, and visualisation. Based on 117 documents of various categories from the years 2012 to 2023, the discourse on German industry decarbonisation is discovered to be dominated by storylines of mainly technological or economic nature. The general sentiment discovered by the different actors is positive with the storylines focusing on establishing the conditions for the industry to decarbonise and no resistance being communicated. The discourse is furthermore dominated by most storylines. 18 out of 27 storylines are being used by more than 56% of all actors. The high overlap in storyline indicates discursive homogeneity. The homogeneity is further indicated through the lack of emerging discourse coalitions and the therewith connected lack of struggles for discursive dominance. One coalition can be defined with some actors being deeper involved and some being less involved in the discourse.
As decisions on the transition path for Germany's industry to decarbonise are still to be taken the lack of discursive struggles has come to my surprise. In the discussion I reflect on how the positive sentiment, the discursive homogeneity and the great number of dominant storylines may come about.
Im September 2023 sind zwei wenig ermutigende Untersuchungen veröffentlicht worden: Das Klimasekretariat der Vereinten Nationen macht in seinem Report zur ersten Globalen Bestandsaufnahme (Global Stocktake) deutlich, dass die bisher zugesagten nationalen Klimaschutzbeiträge bei weitem nicht genügen, um die Pariser Klimaschutzziele zu erreichen. Auch das Update zur Einhaltung der planetaren Grenzen fällt ernüchternd aus: In sechs von neun Bereichen sind die Grenzen teils weit überschritten - auch in Bezug auf den Klimawandel.
Allerdings reichen die ergriffenen Klimaschutzmaßnahmen nicht aus, um die gesteckten Ziele zu erreichen. Suffizienzstrategien und -politik können den Wandel bringen - bei Konsum, Gebäuden, Verkehr, Kreislaufwirtschaft und Energie, wie der Zukunftsimpuls zeigt.
The production of green hydrogen in Germany is more competitive than expected compared to imports. This is the key finding of a meta-analysis conducted by the Wuppertal Institute on behalf of the North Rhine-Westphalia Association for Renewable Energies (Landesverband Erneuerbare Energien NRW).
The hydrogen study focuses primarily on the year 2030 and beyond - and confirms the advantages of green hydrogen produced in Germany from domestic renewable energies, especially when the evaluation is viewed from a holistic system perspective.
Die Bereitstellung industrieller Prozesswärme ist eine zentrale Herausforderung für ein zukünftiges, treibhausgasneutrales Energiesystem. Durch einen Vergleich der Prozesswärmebereitstellung in zwei Energiesystemszenarien werden Gemeinsamkeiten, die auf Richtungssicherheit hindeuten, dargestellt, sowie methodische und inhaltliche Gründe für Abweichungen herausgearbeitet.
Die Bereitstellung industrieller Prozesswärme ist eine zentrale Herausforderung für ein zukünftiges klimaneutrales Energiesystem. In diesem Artikel wird die Vielfalt an etablierten und neuen Energieträgern und Technologien zur treibhausgasarmen bzw. -neutralen Bereitstellung von Prozesswärme vorgestellt. Zudem werden ihre wichtigsten Stärken und Schwächen skizziert, um daraus geeignete Anwendungsfelder und eine Priorisierung ihres Einsatzes zu identifizieren.
There is a growing body of scientific evidence supporting sufficiency as an inevitable strategy for mitigating climate change. Despite this, sufficiency plays a minor role in existing climate and energy policies. Following previous work on the National Energy and Climate Plans of EU countries, we conduct a similar content analysis of the recommendations made by citizen assemblies on climate change mitigation in ten European countries and the EU, and compare the results of these studies. Citizen assemblies are representative mini-publics and enjoy a high level of legitimacy.
We identify a total of 860 mitigation policy recommendations in the citizen assemblies' documents, of which 332 (39 %) include sufficiency. Most of the sufficiency policies relate to the mobility sector, the least relate to the buildings sector. Regulatory instruments are the most often proposed means for achieving sufficiency, followed by fiscal and economic instruments. The average approval rate of sufficiency policies is high (93 %), with the highest rates for regulatory policies.
Compared to National Energy and Climate Plans, the citizen assembly recommendations include a significantly higher share of sufficiency policies (factor three to six) with a stronger focus on regulatory policies. Consequently, the recommendations can be interpreted as a call for a sufficiency turn and a regulatory turn in climate mitigation politics. These results suggest that the observed lack of sufficiency in climate policy making is not due to a lack of legitimacy, but rather reflects a reluctance to implement sufficiency policies, the constitution of the policy making process and competing interests.
