Clean heating with wood

Despite considerable advances in firing technology, harmful particulate matter is produced when wood is combusted. Electrostatic separators, however, filter up to 90 per cent of particulate emissions from biomass boilers. These therefore enable wood burners to use a wider range of fuel and still meet the tightened requirements of Germany‘s 1st Ordinance on the Implementation of the Federal Immission Control Act. The major advantage: Both new and old heating plants can benefit from the new system.  more...

Storing heat until winter

To be able to use summer heat for heating during the winter, hot water storage systems have to be very large. Small storage systems cool down too quickly. With this in mind, seasonal storage tanks have been developed almost exclusively for housing estates or very large consumers. Now researchers have created a new long-term storage system which is also suitable for single-family homes.  more...

Generating syngas from plastic wastes

A newly developed gasification process utilises waste plastics, carbon-containing sorting residues and rubber parts as well as shredded materials in the automotive industry. It can also process chlorine-containing plastic streams with PVC fractions in an environmentally friendly and efficient manner. It produces a purified syngas without flue gas emissions. In the process, lime serves as a transport medium and simultaneously binds halogens and other harmful substances. The gas generated in the shaft kiln can replace valuable primary energy sources such as natural gas in high-temperature processes or be used to generate electricity in efficient gas engines.  more...

The building serves as a heat storage tank

Buildings with high solar shares of fraction require large water tanks to store heat. Researchers have developed a space-saving alternative: excess heat is stored in the ceilings of the building via building element activation. Scientists are currently testing the concept in an experimental building near Hanover. They now have the results of the first year of operation.  more...

Pilot production launched for superconductors

He had to wait 30 years for this moment: Dr Georg Bednorz, a Nobel Laureate in Physics, was present in the Rhineland town of Rheinbach to see the pilot production of high-temperature superconductors begin. It is intended to provide further insights into the manufacture of these almost resistance-free conductors and pave the way for their large-scale series production. The technology is therefore taking a further step towards market maturity.  more...

Stadtwerke Augsburg testing superconducting fault current limiter

The ASSIST project shows how decentralised feed-in systems can be safely integrated into a medium-voltage network. Since 15 March, a superconducting fault current limiter ensures that the electricity fed from a cogeneration engine test rig into the electricity grid belonging to Stadtwerke Augsburg municipal utility company is protected against short circuits. Last week, Thomas Janetscheck from Stadtwerke Augsburg presented the system at the ZIEHL V superconductor conference in Munich.  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...

Thermoelectrics: power from waste heat

Waste heat is produced in all areas of daily life – in industry, homes and transport. In Germany alone, this adds up to a waste heat potential of 300 TWh per year. This energy volume corresponds to nearly half the total energy consumed by German industry. Thermoelectric generators (TEGs) can tap into this huge energy reservoir and transform the "waste energy" without moving parts into a higher form of energy.  more...

Energy storage systems in 2030

What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  more...

Modelling power supply for 2050

By 2050, the goal is for renewable energy sources to generate at least 80 per cent of power. In order to then still guarantee reliable supply at affordable prices, the entire energy system must be adapted and converted in a step-by-step process. The increasing share of fluctuating energy sources requires a flexible system that can react quickly. A research project demonstrates the degree of grid expansion, storage and new regulation opportunities that are technically required for this purpose, and which make economic sense.  more...
