    Industrial site energy integration : the sleeping giant of energy efficiency? ; Identifying site specific potentials for vertical integrated production at the example of German steel production (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: Heat integration and industrial symbiosis have been identified as key strategies to foster energy efficient and low carbon manufacturing industries (see e.g. contribution of Working Group III in IPCC's 5th assessment report). As energy efficiency potentials through horizontal and vertical integration are highly specific by site and technology they are often not explicitly reflected in national energy strategies and GHG emission scenarios. One of the reasons is that the energy models used to formulate such macro-level scenarios lack either the necessary high technical or the spatial micro-level resolution or both. Due to this lack of adequate tools the assumed huge existing potentials for energy efficiency in the energy intensive industry cannot be appropriately appreciated by national or EU level policies. Due to this background our paper describes a recent approach for a combined micro-macro energy model for selected manufacturing industries. It combines national level technical scenario modelling with a micro-modelling approach analogous to total site analysis (TSA), a methodology used by companies to analyse energy integration potentials on the level of production sites. Current spatial structures are reproduced with capacity, technical and energy efficiency data on the level of single facilities (e.g. blast furnaces) using ETS data and other sources. Based on this, both, the investments in specific technologies and in production sites are modelled and the evolvement of future structures of (interconnected) industry sites are explored in scenarios under different conditions and with different objectives (microeconomic vs. energy efficiency optimization). We further present a preliminary scenario that explores the relevance of these potentials and developments for the German steel industry.

    Concepts and pathways towards a carbon-neutral heavy industry in the German federal state of North Rhine-Westphalia (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: The German federal state of North Rhine-Westphalia (NRW) is home to important clusters of energy-intensive basic materials industries. 15% of the EU's primary steel as well as 15% of high-value base chemicals are produced here. Together with refinery fuels, cement, lime and paper production (also overrepresented in NRW) these are the most carbon-intensive production processes of the industrial metabolism. To achieve the ambitious regional and national climate goals without relocating these clusters, carbon-neutral production will have to become standard by mid-century. We develop and evaluate three conceptual long-term scenarios towards carbon-neutral industry systems for NRW for 2050 and beyond: * a first scenario depending on carbon capture and storage or use for heavy industries (iCCS), * a second scenario sketching the direct electrification of industrial processes (and transport) and * a third scenario relying on the import of low carbon energies (e.g. biomass, and synthetic fuels (like methanol) for the use in industries and transport. All scenarios share the assumption that electricity generation will be CO2-neutral by 2050. For all three scenarios energy efficiency, primary energy demand for energy services and feedstock as well as the carbon balance are quantified. We apply a spatial-explicit analysis of production sites to allow for discussion of infrastructure re-use and net investment needs. Possible symbiotic relations between sectors are also included. The robustness of the three conceptualised future carbon-neutral industry systems is then analysed using a multi-criteria approach, including e.g. energy security issues and lock-ins on the way to 2050.

    Bridging the valley of death : a multi-staged multi-criteria decision support system for evaluating proposals for large-scale energy demonstration projects as public funding opportunities (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: There is an increasing pressure that enhanced and novel energy technologies are swiftly adopted by the market to ensure meeting the energy and climate targets. An important issue with such novel developments is their risk to be stuck in the "valley of death", i.e. that their transition to the market is delayed or unsuccessful. Publicly supported demonstration projects could help to bridge the valley of death by reducing barriers to the adoption caused by missing information and perceived risks. A challenge for technology demonstrations in the industrial context is their often high investments that are required to prove their real-world benefits. Given the magnitude of such investments, it becomes crucial that public funding focuses on the most promising demonstration proposals. Structured evaluation processes can help to facilitate the identification of promising proposals and to improve the quality and transparency of decisions. This paper deals with a corresponding multi-staged multi-criteria decision support system (DSS) suggested to the German Federal Ministry for Economic Affairs and Energy. It deals with the evaluation of demonstration proposals across three stages: The first stage represents a filtering stage to identify those proposals relevant for further considerations. The second stage comprises a multi-criteria scoring method drawing on an evaluation against nineteen criteria. The final third stage serves to critically review the need for public funding of well-scored proposals. This contribution outlines the development of the DSS and its design and thus provides insights on proposal evaluating in energy research.

    Demand side management in industry : necessary for a sustainable energy system or a backward step in terms of improving efficiency? (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: Renewable energy plays a key role in the sustainable pathway towards a low carbon future and, despite new supply capacities, the transformation of the energy system also requires the adoption of a method which allows for the integration of increasing amounts of renewable energy. This requires a transition to more flexible processes at an industrial level and demand side management (DSM) is one possible way of achieving this transition. Currently, increased shares of variable renewable energy can cause the electricity supply to become more volatile and result in changes to the electricity market. In order to develop a new dynamic equilibrium to balance supply and demand, sufficient flexibility in demand is required. As adequate storage systems are not available in the short to medium term, the potential for large electricity consumers to operate flexibly is an attractive, pragmatic and feasible option. Recent studies in Germany suggest that there is significant potential for DSM in so-called "energy-intensive industries". However, the figures (which fall in the approximate range of 1,250-2,750 MW positive and 400-1,300 MW negative shiftable load) should be interpreted with caution. The range of industrial processes considered are diverse and vary from plant to plant, with the result that it is difficult to provide accurate calculations of the accumulated potential for Germany or the EU as a whole. Based on extensive surveys and panel discussions with representatives from energy-intensive industries (aluminum, cement, chemicals, iron & steel, pulp & paper), which together account for approximately one third of the industrial electricity demand in Germany, our paper provides an overview of both the opportunities and the barriers faced by DSM. One of the key findings is the possible loss in energy efficiency due to DSM: in order to decrease or increase production depending on the stability needs of the electricity system, plants and processes may no longer operate at their optimum levels. The effects on downstream production must also be taken into account in order to gain a more complete understanding of the overall effects of industrial DSM.

    Deep decarbonisation pathways for the industrial cluster of the Port of Rotterdam (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: 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.

    Electrification of industrial process heat : long-term applications, potentials and impacts (2018)
    Stockholm : Europ. Council for an Energy Efficient Economy
    Details
    Publication Date: 2022-02-18
    Description: Converting electricity into heat offers the opportunity to make of use large scales of renewable (surplus) energy in the long run in order to reduce shut-downs of renewable power plants and to substitute fossil fuels. Electrification seems to be also very promising for industrial heat applications, as it enables high process temperatures to be achieved in a tailor-made and efficient way and enables the utilisation of other energy sources like waste heat, geothermal or ambient heat (via heat pumps). This article analyses theoretical and technical electrification potentials of Steam Generation and Other Process Heat Generation in the following energy-intensive branches: iron & steel, non-ferrous metal, iron foundries, refineries, base chemicals, glass, cement clinker and paper industry in Germany. Literature research, expert interviews as well as own modelling were conducted to determine potentials and their implementation barriers. Based on these methods, market potential to electrify industrial steam generation was estimated. On the basis of two climate protection scenarios, the effects of both a monovalent and a hybrid industrial power-to-heat strategy were quantified with regard to greenhouse gas reduction and energy efficiency (primary energy saving). The pathway towards electrification will be reflected by criteria such as path dependency, dependency of infrastructure and system compatibility. Recommendations for research and development as well as policies are derived from the overall analysis. The article shows that electrification can be an important option to achieving high CO2-savings in the industrial heating sector in a long-term perspective. However, the scenario calculations show that electrification does not in itself guarantee reduction of greenhouse gases or savings of primary energy. To reach these goals, it is essential to further develop industrial heat pumps and to map electrification and further development of renewable energy (including infrastructure such as power networks and storage facilities) in a concerted strategy.
