Test methods for practical key system figures relating to energy efficiency

Measurements on real heat generator plants show that efficiency parameters as determined by calculation sometimes deviate considerably from the values registered by measurement technology. This is especially true for heat pumps and micro CHP plants. The annual performance factor is decisive in terms of their economic success. more...

Network-neutral energy-plus district Geretsried

Researchers at Munich University of Applied Sciences and TU Dresden have developed an innovative energy concept for an energy-plus district, which is to be implemented in the “Neue Mitte” of Geretsried (Bavaria) by the end of 2019. The concept combines the utilisation of different energy technologies with the goal of electrical network neutrality, i.e. maximising own coverage of electricity requirements and own use of the generated electricity. more...

Superconducting generator on the test stand

Compact design, low tower head mass and good transportability: The high-temperature superconducting generator, which was developed in the EcoSwing research project, is to be used in the next generation of multi-megawatt turbines. The practical feasibility of the concept is being verified in a test campaign on Fraunhofer IWES’ nacelle test rig and in a follow-up field test in a two-blade system in Denmark. more...

Developing multifunctional façade elements

As the outermost layer of the building envelope, the façade performs numerous functions. They are to be intelligently combined to create a system that permits the application of cost-effective, multifunctional façade systems. To do this, scientists are developing a façade element with integrated organic photovoltaics, textile sun protection, a sustainable insulating material and the sensors necessary for control. The next step is to test the elements on the south façade of a multi-storey residential building. more...

Adapting chlorine production to the electricity supply

The chemical industry is the second largest consumer of electricity within German industry. Using the example of energy-intensive chlorine-alkali electrolysis, scientists are now investigating to what extent this process can contribute to managing loads in the power grid. To achieve this the production needs to be adapted to the intermittent electricity supply. more...

Heat storage system with segmental design demonstrates its qualities

In the “OBSERW” research project researchers have developed an innovative above-ground storage tank built using a cost-saving segmental construction method. This required a complete overhaul of conventional storage constructions and building technology. Numerous technical issues were put to rest, such as the temperature-resistant sealing of segments. more...

Storing power and heat in the district

Sustainable energy provision is to be developed for the urban district of Rüsdorfer Kamp in Heide. The QUARREE100 research project is investigating how the district could be fully supplied with local or regional renewable energy sources. One goal is to integrate the regionally generated wind power into the regional energy system in an economically efficient and system-serving way. more...

Material loading in flexible power plants

The conditions for operating conventional coal and natural gas power plants are changing considerably as a result of their combination with renewable energies. In future they will run more frequently under partial loads, have considerably more start-up and shut-down cycles, and the components will be subjected to greater and more diverse loads. Scientists have investigated the thermal and mechanical loads on thick-walled components in power plants under the new conditions. At any given safety level, the aim is to more precisely calculate the stability of components in regard to their damage and thus economically optimise their deployment times. more...

Testing climate-neutral districts in the real-world laboratory

How can energy efficiency measures and the utilisation of renewable energy sources enable districts to get by with virtually no fossil fuel? How can smart networking of power, heat and mobility be achieved? Scientists and other stakeholders are investigating these questions in six flagship projects. Initial results and local challenges were outlined by the research teams in a panel discussion at the Berliner Energietage conference. more...

Smart Green Tower becomes an energy producer

The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries. more...
