Test benches offer reproducible conditions compared to testing new wind turbines in the open field. But is this data enough for certification alone?
Bifacial silicon solar cells achieve an efficiency of 21.6 per cent. New ultra-thin wires cut more wafers from a silicon crystal.
A new screen printing process enables the printing of narrow contact fingers on silicon solar cells of less than 20 microns.
Straw and chicken manure accumulate in large quantities and are suitable for material and energy recovery in biogas plants.
Compared to pumped storage tanks, liquid air energy storage tanks can be installed wherever they are needed, regardless of the local conditions.
New industrial gas turbine with an output of less than 25 megawatts is suitable for use in combined gas and steam turbine plants.
Test rigs ensure reproducible conditions for certification tests. The manufacturers save time and money.
Using electricity from waste incineration plants to produce hydrogen, which in a further step reacts with Carbon dioxide to form methanol.
If a production pump of a geothermal power plant fails, it is removed from the borehole together with the production pipes and transported to the surf
