The Port of Rotterdam is an important industrial cluster mainly comprising of oil refining, chemical manufacturing and power and steam generation. In 2015, the area accounted for 18 % of the Netherlands' total CO2 emissions. The Port of Rotterdam Authority is aware that the port's economy is heavily exposed to future global and EU decarbonization policies, as the bulk of its activities focuses on trading, handling, converting and using fossil fuels. Based on a study for the Port Authority, our paper explores possible pathways of how the industrial cluster can keep its strong market position in Europe and still reduce its CO2 emissions by 98 % by 2050. The "Biomass and CCS" scenario assumes that large amounts of biomass can be supplied sustainably and will be used in the port for power generation as well as for feedstock for refineries and the chemical industry. Fischer-Tropsch fuel generation plays an important role in this scenario, allowing the port to become a key cluster for the production of synthetic fuels and feedstocks in Western Europe. The "Closed Carbon Cycle" scenario assumes that renewables-based electricity will be used at the port to supply heat and hydrogen for the synthetic generation of feedstock for the chemical industry. The carbon required for the chemicals will stem from recycled waste. Technologies particularly needed in this scenario are water electrolysis and gasification or pyrolysis to capture carbon from waste, as well as technologies for the production of base chemicals from syngas. The paper compares both scenarios with regard to their respective technological choices and infrastructural changes. The scenarios’ particular opportunities and challenges are also discussed. Using possible future pathways of a major European petrochemical cluster as an example, the paper illustrates options for deep decarbonisation of energy intensive industries in the EU and beyond.
Die atompolitische Wende der Bundesregierung hatte zahlreichen Spekulationen und Befürchtungen Raum gegeben. Es wurde gemutmaßt, dass Deutschland zum Nettostromimporteur werden könnte, sollten die Kraftwerke (wie im Sommer 2011 beschlossen) dauerhaft außer Betrieb bleiben. Darüber hinaus nahm man an, dass die in Deutschland entfallende Stromerzeugung durch Kohlekraftwerke oder durch Importe aus französischen oder tschechischen Atomkraftwerken ersetzt würde und dass Strompreise sowie CO2-Emissionen deutlich ansteigen würden. Inzwischen liegen vorläufige Energiebilanzen und Marktdaten für das Jahr 2011 vor, die viele dieser Befürchtungen widerlegen. Der hier vorgenommene Ausblick auf die mögliche Entwicklung in den kommenden Jahren zeigt zudem, dass die Bilanz von 2011 keine Momentaufnahme sein muss, sondern dass der gegenüber 2010 wegfallende Kernenergiestrom - bilanziell gesehen - voraussichtlich bereits ab 2013 allein durch eine erhöhte regenerative Stromerzeugung kompensiert werden kann.

Purpose - Iran as an energy-rich country faces many challenges in the optimal utilization of its vast resources. High rates of population and economic growth, a generous subsidies program, and poor resource management have contributed to rapidly growing energy consumption and high energy intensity over the past decades. The continuing trend of rising energy consumption will bring about new challenges as it will shrink oil export revenues, restraining economic activities. This calls for a study to explore alternative scenarios for the utilization of energy resources in Iran. The purpose of this paper is to model demand for energy in Iran and develop two business-as-usual and efficiency scenarios for the period 2005-2030.
Design/methodology/approach - The authors use a techno-economic or end-use approach to model energy demand in Iran for different types of energy uses and energy carriers in all sectors of the economy and forecast it under two scenarios: business as usual (BAU) and efficiency.
Findings - Iran has a huge potential for energy savings. Specifically, under the efficiency scenario, Iran will be able to reduce its energy consumption 40 percent by 2030. The energy intensity can also be reduced by about 60 percent to a level lower than the world average today.
Originality/value - The paper presents a comprehensive study that models the Iranian energy demand in different sectors of the economy, using data at different aggregation levels and a techno-economic end-use approach to illuminate the future of energy demand under alternative scenarios.
The need for an "Energy Roadmap 2050" triggered a multitude of studies that were conducted between 2009 and 2011, which again contained a multitude of decarbonisation scenarios, which achieve the EU's long-term emission mitigation target of reducing greenhouse gas emissions by at least 80% until 2050 (relative to 1990 emissions). The variety of important analysis is difficult to compare and utilize for specific and timely policy decisions. Thus the Smart Energy for Europe Platform (SEFEP) has commissioned a comparative study of relevant energy scenario studies for Europe. The findings of this comparative study are summarized here briefly.
Nach einer langen Phase der Stabilität ist die Stromwirtschaft in den vergangenen 15 Jahren stark in Bewegung geraten. Zunächst stand der Wechsel von staatlich überwachten und regulierten Gebietsmonopolen hin zu liberalisierten Erzeuger- und Verbrauchermärkten an. Im Moment befinden wir uns in einem ähnlichen Umbruch, weg von konventioneller hin zu erneuerbarer Energieerzeugung.
Im vorliegenden Beitrag soll der Leitfrage nachgegangen werden, ob die Paradigmen der einzelnen Phasen miteinander vereinbar sind, welche noch immer ihre Daseinsberechtigung haben und welche modifiziert werden sollten.
Several low-carbon energy roadmaps and scenarios have recently been published by the European Commission and the International Energy Agency (IEA) as well as by various stakeholders such as Eurelectric, ECF and Greenpeace. Discussions of these studies mainly focus on technology options available on the electricity supply side and mostly omit the significant challenges that all of the scenarios impose on the energy demand side.
A comparison of 5 decarbonisation scenarios from 4 of the most relevant recent scenario studies for the EU shows that all of them imply significant efficiency improvements in traditional appliances, usually well above levels historically observed over longer periods of time. At the same time they assume substantial electrification of transportation and heating. The scenarios suggest that both of these challenges need to be tackled successfully for decarbonising the energy system.
With shares of renewable electricity reaching at least 60 % of supply in 2050 in almost all of the decarbonisation scenarios, the adaptation of demand to variable supply becomes increasingly important. This aspect of demand side management should therefore be part of any policy mix aiming for a low-carbon power system.
Based on a quantitative analysis of 5 decarbonisation scenarios and a comparison with historical evidence we derive the (implicit) new challenges posed by the current low-carbon roadmaps and develop recommendations for energy policy on the electricity demand side.
