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...

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...

Solar Decathlon competitions compact

The Solar Decathlon student competition challenges the participating teams to develop completely solar-powered houses. More than 250 buildings have already been built in the 13 competitions that have taken place to date. A considerable amount of investigative spirit has gone into designing all of them, they are comparable and well documented. A freely accessible online database now provides a comprehensive overview and the framework for systematically evaluating the innovations and results.  more...

Solar thermal energy reduces surface area of geothermal heat collectors

For heat pumps with geothermal heat collectors, unglazed solar collectors offer several advantages as a secondary heat source. The surface area requirement for laying geothermal heat collectors is reduced by up to 50 percent without resulting in depletion of the ground or critical freezing conditions. Researchers at the Institute for Solar Energy Research (ISFH) in Emmerthal closely investigated this together with partners in a research project. The simulation model developed is available for simulation software TRNSYS, information materials for simplified designing rules for planners will be published shortly.  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...

New administrative facility with energy-plus concept

In 2013, the City of Freiburg held a competition for the construction of a new central administrative facility, including town hall, to consolidate its various agencies spread across the municipal area. The objective being two-fold: to produce an outstanding architectural design and to maximise energy efficiency. Monitoring measures put into effect upon commissioning are intended to reveal whether operation of the new energy-plus building fulfils the promise evident at the planning stage.  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...

Reactive power management in practice

The energy transition presents new challenges for grid operators. One aspect of this is the provision of reactive power. Reactive power flows in grids affect voltage and grid stability. Currently, this is primarily compensated for by conventional power stations. With the decommissioning of large nuclear power plants, the power system needs new solutions.  more...

Smart Grid at favourable cost

The same technology for decades keeping street lights illuminated has the potential to motivate power consumers and decentralised generators to adopt system-friendly behaviours. The Fraunhofer Institute for Solar Energy Systems (ISE) has investigated how dynamic power tariffs can be transmitted based on ripple control technology together with project partners. Investigations involved sending electricity market prices across the regional power grid using tariff switching times.  more...
