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...

Optimising heat pumps for multi-family homes

Solutions for the application of low-exergy systems are being developed to supply heat to existing multi-family homes. This building services equipment includes electric and gas heat pumps as well as heat transfer and ventilation systems. Different system concepts are assigned to different building types and refurbishment processes and then evaluated. The aim is to realise and evaluate the developed heat pump systems and components in exemplary refurbishment projects.  more...

Storing heat in mines

What happens to mines that are no longer in use? Could they be used to store heat? Researchers are hoping to find this out and are conducting tests in the former Prosper-Haniel hard-coal mine in Bottrop to investigate whether it is suitable for underground heat storage. The GeoMTES research project is developing storage concepts for this purpose and a feasibility study will be carried out by September 2018. The modelling of the pit structure has now been completed.  more...

Effect of wind farms on flight safety

The approval of new wind turbines in the vicinity of radar or navigation systems in air traffic often causes conflicts, which sometimes end in court. It is undisputed that wind turbines can influence the signals emitted by radar systems and omnidirectional radio range beacons. So far, there has been a lack of scientifically valid, reproducible investigations on the actual extent. Together with their partners, the Physikalisch-Technische Bundesanstalt has developed a new measurement method and numerical simulation methods and has now published first results.  more...

Solar cell uses front and back

So-called bifacial solar cells can convert incident light into electrical current both on their fronts and backs. They are up to 30 per cent more powerful than conventional monofacial cells that use only their fronts. The hitherto very complicated production of such double-sided solar cells has now been made simpler and less expensive by means of a newly developed doping process.  more...

Keeping the oil in the engine

Each time the fuel-air mixture is ignited in petroland diesel engines a small portion of the gases flows from the combustion chamber into the crankcase as leakage current. For the engines to function optimally, it is necessary to dissipate these so-called blow-by gases and separate the engine oil droplets contained within them. This reduces the pollutant emissions and oil consumption of the engines. For modern, higher-compression engines, researchers have developed new and effective separation systems that undercut the more stringent emission limits for oil mist.  more...

From air base to residential neighbourhood

A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  more...

Modern living in an historic urban district

The Margaretenau residential district in Regensburg is being modernised to improve its energy efficiency. The designers are developing a solar-active and -adaptive exterior render system as a replacement for conventional thermal insulation for the facades. This should increase the solar yields and improve the thermal comfort inside the buildings. The energy supply will be provided by a new and efficient hybrid heating system consisting of cogeneration and heat pump technology.  more...

When are flexible district heating systems beneficial?

The integration of thermal storage in cogeneration plants leads to more flexibility in district heating networks because the power generation can be better adapted to the power requirements. Power-to-heat systems couple the electricity and heating sectors to utilise renewable electricity for district heating. Together with partners from science and industry, researchers at the TU Berlin have investigated when the construction of heat storage and power-to-heat systems can be economically and ecologically beneficial.  more...

Closing security loopholes in power grids

The way in which electricity distribution networks operate is changing considerably as a result of the energy transition. Decentralised systems are increasingly being connected via the Internet with the central control rooms of the energy providers for control purposes. The risks that can arise due to security loopholes in the information system are accordingly growing. In a guide, researchers at Bremen University of Applied Sciences show how the operational management can be secured and how the risks can be limited if measures fail.  more...
