ZO.RRO – Zero Carbon Cross Energy System:
Transformation of the energy system using the example of Thuringia

The first phase of energy transition has been realized by the establishment of renewable energies. The current second phase is determined by further efforts in: the expansion of renewable energies, the reduction of energy consumption (CO2 emissions), the increase in energy efficiency, the optimization of energy systems and the coupling of the electricity, gas, heating and mobility sectors.

This is exactly where ZO.RRO comes in and researches new approaches and solutions for the systemic energy transition.

The joint project ZO.RRO is headed by the Ilmenau University of Technology.

ZO.RRO is researching how the future energy supply can be made CO2-free and wants to optimize the energy system with self-developed solutions. One of the important research goals is the development and testing of CO2-free system services by using cross-sector flexibility options.

In addition, ZO.RRO uses the example of Thuringia to test how producers and consumers could interact in an optimal system and how consumers can exploit synergies among themselves. ZO.RRO involves important Thuringian experts, multipliers and companies in the project. It explicitly addresses small and medium-sized companies in industry, trade and the energy sector with an interest in supporting the project in the research, development and testing of industry-related flexibility options.

The research work could serve as a model for other regions in Germany in the future.

Project objectives

Power generation with renewable energies is well established in Germany. The energy transition is moving into the next phase and focuses on the decarbonisation of the entire energy supply. The use of more efficient technologies and systems, the coupling of the electricity, heat and mobility sectors, and improved interaction between consumers and producers play an important role in this process. This is where ZO.RRO comes in and researches new approaches and solutions for systemic energy system transformation. The research goal is to enable a CO2-free energy supply in the future. The project focuses on system services, as they account for up to 20 percent of CO2 emissions in energy supply. After a concept phase, the feasibility of the solutions developed will be tested and evaluated together with representative demonstrators.

Fields of work

  • Energy system analysis & application optimization

    Simulative investigation of the practice-relevant production and consumption scenarios in a developed model for cross-sectoral energy systems. We optimize the use of all available generation facilities, storage facilities and flexibility potentials within the framework of the energy-economic management of the cross-sectoral energy supply system, taking into account the fluctuating feed-in and energy requirements.

  • Cross-sectoral network management

    We design the cross-sectoral network management and develop a system design for the provision of system services in order to derive and demonstrate deployment and security concepts for CO2-free energy supply.

  • IT infrastructure & IT systems

    We design, conceptualize and test exemplary new IT infrastructure and systems in which deployment plans for CO2-free system services can be created and implemented. These can be, for example, management systems for storage and flexibility offers (storage-flexibility-offer-platform). For this purpose, a new type of supervisory authority is being set up as a superordinate recording, planning/coordination, monitoring and accounting instance.

  • Industry & big business

    We identify state-wide, cross-sectoral flexibility potentials in industry and commerce with a focus on CO2-free options. We address the most important sectors in all regions of Thuringia and SMEs (small and medium-sized enterprises) with previous experience from energy efficiency projects. The aim is to identify standard solutions and recommendations for action and to concretize flexibilization potentials in the respective sectors.

  • Demonstration projects & overall integration

    We are preparing the demonstrator phase, in which the cross-sectoral energy supply will be implemented and examined for feasibility with demonstrators in Thuringia. We integrate this into an overall concept. The aim of the investigation is to answer the question of what capacities are required to minimize the use of conventional power plants.

  • Investigation scenario Thuringia

    We determine Thuringian-specific parameters (typical profiles or requirements for feed-in, final energy, utilization energy, loads) for a future, CO2-free and cross-sectoral energy supply system. In doing so, we involve partners from the Thuringian economy, companies and multipliers by offering workshops and specialist events throughout the entire project. Our targeted public relations work ensures transparency and addresses the broadest possible audience in Thuringia.

Key terms

  • Systemic energy transition

    Following an overall system approach, all individual components of the system are considered, assessed in terms of their efficiency and cost-effectiveness and finally interconnected. The central components are the sectors (electricity, heating / cooling, mobility and industry), the options of flexibility, the interaction of producers and consumers, the digitalization of the energy industry as well as the CO2-neutral provision of system services.

  • Sector coupling

    Warum betrachtet das ZO.RRO-Projekt Sektorenkopplung?
    Das ZO.RRO-Projekt zeigt, wie Unternehmen Ihren CO2-Ausstoß minimieren können. Eine Möglichkeit ist der Einsatz von Technologien, die die Sektoren Strom, Wärme, Gas und Mobilität verbinden, um Erneuerbare Energie vielseitig nutzbar zu machen. Die Sektorenkopplung umfasst beispielsweise den Einsatz von Batteriespeichern, Wärmepumpen (Power-to-Heat) und Elektrofahrzeugen (Power-to-Mobility) wie auch die Wasserstoffgewinnung aus grünem Strom (Power-to-Gas).

  • Decarbonization

    85 percent of German greenhouse gas emissions are due to the provision of energy in the form of electricity, heat and mobility. 98 percent of the emissions are carbon dioxide, the rest consists of methane and nitrous oxide. Since 1990, carbon dioxide emissions have decreased from 990 million tons to 750 million tons, which corresponds to a reduction of 27.5 percent [UBA]. Germany's most important goals are to reduce emissions by 40 percent until 2020 and by 80-95 percent until 2050. In the Paris Agreement, Germany committed itself internationally to taking actions to limit global warming to <2 degrees Celsius. Source: UBA1

  • Interaction between consumers and producers:

    State of the art is that the capacity of production is controlled in accordance with the current demand. New concepts extend this control system and include consumers who can vary the scope or timing of their energy demand. This flexibility can be expanded with storage solutions. The expanded control includes the expansion of communication with, for example, "smart meters" and new legal regulations.

  • System services

    Warum betrachtet das ZO.RRO-Projekt Systemdienstleistungen?
    Für ein CO2-freies Energiesystem der Zukunft müssen neben der Energieerzeugung auch alle notwendigen Maßnahmen zur Sicherung und Wiederherstellung der Netzstabilität (sog. Systemdienstleistungen) CO2-frei erbracht werden.

    Definition:
    The system services include measures that ensure stable network operation. In addition to the balancing power, i.e. the compensation of differences between actual consumption and scheduled production, the most important measures include network restoration after a supply failure and reactive power compensation.

  • Flexible Betriebsweisen

    Warum betrachtet das ZO.RRO-Projekt flexible Betriebsweisen?
    Das ZO.RRO-Projekt gibt individuelle Empfehlungen, wie Unternehmen ihre CO2-Emissionen senken können. Eine Option sind flexible Betriebsweisen in der Produktion. So können Prozessschritte, je nach Verfügbarkeit Erneuerbarer Energie, zeitlich verzögert erfolgen (Lastverschiebung) oder Produktionsmaschinen unterschiedlich ausgelastet werden (Teillastbetrieb).

  • Industrielle Flexibilitätsoptionen

    Warum betrachtet das ZO.RRO-Projekt industrielle Flexibilitätsoptionen?
    Das ZO.RRO-Projekt gibt individuelle Empfehlungen, wie Unternehmen künftig auf die fluktuierende Verfügbarkeit Erneuerbarer Energie reagieren können, um den störungsfreien Produktionsablauf zu gewährleisten und dabei CO2-Emissionen und -Kosten (ab 2021) zu senken.
