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...

Video inspection tool brings light into the darkness

Scientists in Karlsruhe are developing a camera inspection system for deep geothermal drilling holes. The device must be able to withstand strong pressure and high temperatures. This presents a particular challenge for the electronic components. A first draft design for the system has now been completed.  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...

Exhaust heat cools lorry cab

Time for a break! The driver stops his lorry at the truck stop. To ensure that the cabin also remains cool even in summer, the engine also continues idling when the lorry is parked, often for hours. This produces noise and wastes fuel. However, researchers at the University of Stuttgart have now demonstrated that pleasant temperatures can still be reached even when the engine is switched off and there are no additional energy inputs. They have developed a special adsorption chiller. This utilises the exhaust heat produced while driving for air-conditioning the parked vehicle.  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...

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...

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...

Storing surplus electricity in the natural gas network

Surplus electricity can be used in Power-to-Gas systems to generate hydrogen by means of electrolysis. Downstream methanation provides a possibility for storing the remaining gas that cannot be directly used or fed into the natural gas network. The initial, highly promising results for a newly developed biological process have now been presented. The test facility has a low energy requirement and the process is continuous. The system is suitable for decentralised and small systems.  more...

Expanding the electricity grid for the energy transition

Experts from science, industry and politics met on 22 and 23 September 2016 at the first status conference on "Future-proof Power Grids" in Berlin. More than 300 delegates followed the invitation of the German federal government and offered an insight into their current research on the subject of grid expansion. Since the beginning of the "Future-proof Power Grids" funding initiative in 2013, the participating German federal ministries have funded more than 300 projects with around 140 million euros.  more...
