ENERGY

For many years, the FiW has a leading role in doing research on innovative concepts for energy supply and possibilities for energy optimisation, especially in the wastewater sector. Regional energy supply concepts were made on district level and for large individual consumers like indoor swimming pools. The FiW offers different services. We make energy analysis for municipal and industrial wastewater treatment plants as well as coordinate and implement interdisciplinary research projects. Furthermore, we do consulting services for wastewater treatment plant operators, municipalities and industrial companies.

We transfer our experience about energy to international cooperation projects. For example in studies to increase energy efficiency at sewage treatment plants in other countries or by the installation and integration of renewable energies into existing supply concepts. Anaerobic sewage sludge stabilisation with energetic use of the digester gas is often not done outside of Germany. Here the FiW can support the development of concepts for process changes.

PROCESS DEVELOPMENT & OPTIMISATION

For many years, the FiW did research in the wastewater sector for the development of energy concepts based on hydrogen. With this concept surplus regenerative energy could be stored. We do studies, think of new concepts and also process development or optimisation. For example, we want to add oxygen, produced electrolytically, into the wastewater treatment process and make concrete designs for hydrogen production, storage, transport and use.

In this context, the FiW is doing research on available technologies for the separation and reuse of CO2 from different waste gas sources. It becomes clear that CO2-neutral fuels and CO2-neutral basic chemical materials can be produced by methanol synthesis. That is why the methanol synthesis has is a key element of the work.

ENERGY MANAGEMENT

When considering future energy supply systems, the use and storage of (surplus) thermal energy is getting more attentionRegardless of many development and optimisation efforts of available components, a special need is recognised in the networking of the entire energy infrastructure, the interaction of the individual components and the provision of regenerative energy sources. These models can also include the sewers. If the simulation for the sewer network is also made for hydraulics and materials, the results of the data can be used as parameters for the optimisation. For example, modelling of the sewer network can be used to show the behaviour of impoundment, remobilisation and discharge. In addition, the effects of shock loads but also steady loads on the sewage treatment plant can be seen. From these simulation results, action and optimisation potentials can be developed for operators of wastewater treatment plants and network providers.

HEAT GROUP SYSTEMS

Dynamic simulations with computers make it possible to analyse complex systems. In addition, it is possible to design control units with the help of the simulation and to analyse the system behaviour of the heating network. In the planning phase, the simulation is used to create a technically and economically optimal dimensioning and planning of the heating network, including storage. Our motivation is the real implementation of innovative heat island concepts in a project region.

ENERGY REVOLUTION

To realize the big energy revolution with success, especially at the base, overall strategies, technical innovations, social innovations as well as new cooperation and marketing models are necessary. The project "Regional Dialogue Energy Transition - render", funded by the German Federal Ministry of  Education and Research, is developing new perspectives in this context together with many stakeholders by using the example of Aachen and its city region (Germany).
