Fuel cell generates electricity and heat for homes

Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  more...

Assessing solar houses in energy and economic terms

With the German Energy Savings Ordinance 2016, the maximum value allowed for the annual primary energy requirement for new residential buildings has been reduced by a quarter. This is not a problem in solar houses: they require a maximum of 15 kWh/(m2p.a.) of primary energy for heating energy and auxiliary power and are therefore well below the requirements of passive houses. The cost of this good CO2 balance can be determined using a newly developed simulation method.  more...

Rotor blades with elastic front edges

During the course of their operation, countless raindrops land on the leading edge of the rotor blades used on wind turbines. Despite the special coatings and films applied to these edges, this damages the surface. Over time, this causes erosion to the leading edge of the blades. A research project is therefore testing a new approach: in future, elastic leading blade edges could solve the problem.  more...

First liquid salt storage facility with one tank

High-temperature heat storage tanks ensure that power plants work more flexibly and industrial process heat can be temporarily stored. Researchers at the German Aerospace Center (DLR) have therefore developed a heat storage tank for temperatures up to 560 degrees Celsius, which stores the heat in molten salt. Construction work on the testing facility began at the start of July 2016.  more...

Pilot production of thermoelectric modules

Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...

Ceramic cube reduces gas losses

Scientists have developed a new ceramic heat exchanger for industrial furnaces. This can transmit considerably more exhaust heat to the combustion media than the metal recuperators currently used in high-temperature furnaces in the process industry. The new ceramic recuperator thereby decreases the exhaust gas losses to less than 25 per cent.  more...

Hydrogen – storing energy in metals

Metal hydrides store hydrogen and heat. Their use in thermochemical storage systems is hampered, however, by the material's poor heat conductivity. To increase the charging and discharging performance, researchers are pelletising the material together with graphite, which has a high thermal conductivity. With different metal hydrides they can cover the temperature range from room temperature up to 400 degrees Celsius.  more...

Dry lignite increases flexibility

Shoulder to shoulder with the energy transition: Coal plants are becoming more flexible to enable more energy from renewable sources to be used to supply the electricity grid. The output from renewable sources is currently not enough to meet the entire energy demand in Germany at all times. But their share is growing. This is transforming the role of conventional power plants: instead of providing constant base loads, they now have to cover fluctuating residual loads. To achieve this, pilot burners with integrated plasma ignition are being used for the first time in the world at a power plant in Jänschwalde in Brandenburg. These are using dry lignite as the fuel.  more...

A town acts as a storage system

How can urban regions contribute more to the energy transition? To find this out, scientists are investigating virtual energy storage systems in Herten in North Rhine-Westphalia and in Wunsiedel in Bavaria. The field trial started on 30 June 2016.  more...

Berlin drills for the heating transition

The research project ATES is to clarify whether or not Berlin's geological subsurface aquifers are suitable for the seasonal storage of heat and cold. These aquifers could store excess heat from summer up until the heating season starts, and then supply entire neighbourhoods. At the end of February 2016, the GFZ German Research Centre for Geosciences  in Potsdam started drilling an exploration well on the campus of TU Berlin. The well has now reached its final depth of 560 metres. In a BINE interview, Professor Ernst Huenges speaks about goals and prospects.  more...
