POWER-2-RESCUE
  • Full title: Mobility Transition in Emergency Medical Services, Fire Department, and Disaster Relief in Lusatia (POWER-2-RESCUE)
  • Coordinator: Björn Steiger Foundation (DE), Brandenburg Institute for Society and Security (DE)
  • Funding agency: Federal Ministry for Digital and Transport (Funding program "mFUND", grant no. 19FS1012C)
  • Duration: 2023-07-01 – 2025-09-30
  • Project manager at BTU:
    • Univ.-Prof. Dr. Lars Röntzsch
  • Summary:

    The POWER-2-RESCUE project, led by the Björn Steiger Foundation in collaboration with the Brandenburg Institute for Society and Security and the Brandenburg University of Technology Cottbus-Senftenberg, examines the impact of the mobility transition on emergency services, fire departments, and disaster management in the 'Health Model Region Lusatia'. This initiative is driven by the impending end of the approval of internal combustion engines in the EU, necessitating the introduction of alternative propulsion technologies for authorities and organizations with security tasks (BOS). This requires new decision-making bases for municipalities and districts, as well as early information for manufacturers about future investment needs. As part of the project, a feasibility study will be conducted to explore approaches for environmentally friendly propulsion systems and the necessary refueling and charging infrastructure for emergency vehicles used by fire departments, emergency services, and disaster management. The foundation will be data and scientific forecasts provided by end-users to develop practical solutions. Two expert workshops with end-users will be held to develop practical and innovation-oriented content, identify needs, and propose solutions. This will form the basis for a subsequent exploratory project. A literature review will support the socio-economic contextualization of the topic, and the findings will be published in a study. Finally, the results will be discussed and evaluated in a workshop with manufacturers and equipment suppliers. The project focuses particularly on the Lusatia region, which faces significant economic restructuring due to the planned phase-out of lignite by 2038. At the same time, the reform of the hospital structure and emergency care requires an adaptation of regional infrastructures to ensure reliable public services. POWER-2-RESCUE is the first nationwide project to comprehensively and openly address the future operational capability of BOS institutions in the face of the energy transition. It provides early decision-making aids for investments in the emergency services of the future.

CO2Bi
  • Full title: Utilization and storage of fluctuating regenerative energies and CO2 emission reduction - application-oriented qualification of the ABRW process for biomethanation
  • Funding agency: Fachagentur Nachwachsende Rohstoffe e. V. (FNR)
  • Funding reference: 2220NR200B
  • Duration: 2021-11-15 – 2024-12-31
  • Project partners:
    • BTU Cottbus-Senftenberg, Chair of Waste Management
    • HAVER & BOECKER OHG, Oelde
    • Prof. (retired) Dr.-Ing. habil. Gunter Busch, Dresden
  • Project managers at BTU:
    • Univ.-Prof. Dr. Lars Röntzsch
    • Krunal Thummar, M.Sc.
  • Summary:
    The aim of the project is the integration of biomethanation in the innovative ABRW process (anaerobic bio-reactive permeable wall) in the energy network of wind power plants, emission-intensive industrial processes and biogas/biomethane plants or mechanical-biological waste treatment plants for methane feed into the natural gas network. The central subject is the use of regeneratively produced hydrogen by reacting with CO2 and producing methane that can be fed into the grid. This is intended to promote the indirect use of renewable electricity and to achieve its storage and transport. As a gaseous energy source, fuel or chemical starting material, it can be linked to other sectors and economic cycles. The reduction of greenhouse gas emissions is directly linked to the technological solution. Instead of separation, CO2 is used in particular, so that one can speak of a real CO2 circular economy.
Interreg VA
  • Full title: Energy storage of the future in the Spree-Neiße-Bober region
  • Funding agency: Cooperation program Interreg VA Brandenburg-Poland 2014-2020 (European Regional Development Fund)
  • Duration: 01/01/2020 – 03/31/2023
  • Project partners:
    • CEBra – Center for Energy Technology Brandenburg e.V., Cottbus
    • University of Zielona Góra, Poland
    • City of Zielona Góra, Poland
  • Project managers at BTU:
    • Univ.-Prof. Dr. Lars Röntzsch
    • Dipl.-Ing. Steffen Swat
  • Summary:
    The Interreg VA program is funding a project for cross-border knowledge transfer in the field of energy storage technologies and energy efficiency. As part of the German-Polish EU funding project, the partners: CEBra - Center for Energy Technology Brandenburg e.V., the BTU Cottbus-Senftenberg, the University of Zielona Góra and the city of Zielona Góra work closely together. The cooperation of the scientific partners in the Interreg VA project is focused on expanding the range of training courses and knowledge transfer in the field of energy storage technologies and energy efficiency. Specifically, it is about the realization of completely new, in-depth, thematic training offers (several days) on the basis of the additional expansion of training capacities. Integrated into the program is the reciprocal implementation of qualified, target group-oriented, multi-day specialist events in Cottbus and Zielona Góra/Nowy Kisielin. Due to the agreed division of labor/specialization between the two universities, each side can contribute its strengths to the partnership. In this way, it is possible to convey in-depth specialist knowledge. CEBra e.V. and BTU are concentrating on the topic of electrical and chemical storage and are making their training capacities available for this purpose, including the new training positions for the Polish partners. The new project serves to intensify cross-border knowledge transfer as the basis for application-oriented and knowledge-based value creation in the region. The project promotes the development of a common European training and research landscape and strengthens the competitiveness of the region on a European scale.
StaGruV–EwiK
  • Full title: Site-related basic assessment and preliminary planning for the pilot project "Energy transition on a small scale"
  • Funding agencies: Federal Ministry for Economic Affairs and Energy (BMWi) / Federal Office for Economic Affairs and Export Control (BAFA)
  • Duration: 05/01/2021 – 06/30/2022
  • Project partners:
    • Rolls Royce Solutions GmbH
    • CEBra - Center for Energy Technology Brandenburg GmbH
  • Project managers at BTU:
    • Univ.-Prof. Dr. Lars Röntzsch
    • Gisse Alvarado Huanay, M.Sc.
  • Summary:
    The energy transition is to be demonstrated on a small scale using cross-sector microgrids as a replacement or supplement to large central power plants and for the decentralized production of fuels, and the interaction of renewable energies, energy storage, decentralized hydrogen power generation systems and Power-to-X systems is to be mapped. This includes the integration of a power-to-liquid system for the use of regionally generated electricity from renewable energies for decentralized e-fuel production. This promotes a cross-sectoral, CO2-neutral energy supply. In particular, the climate-neutral supply of fuels for applications in the transport sector that cannot be electrified or are difficult to electrify, such as shipping and air traffic, is demonstrated and the use of these regenerative fuels (e-fuels) both in test stands (testing of aircraft engines at Rolls Royce in Dahlewitz, ship engines at MTU Friedrichshafen), field systems as well as laboratory technology. This project represents a first step towards realizing the vision of decentralized fuel production coupled with a decentralized hydrogen-based energy system. The project paves the way for the key technology for generating e-fuels from renewable energy, it enables the transformation and expansion of existing industrial sites with industrial policy perspective for the region. A detailed location analysis is to be carried out in the first project phase. Furthermore, the creation of a detailed technological concept / preliminary planning for a DEMO system and its economic analysis.
