En­er­gy re­search

The largest artificial Sun in the world

The largest ar­ti­fi­cial Sun in the world

March 22, 2017  Syn­light con­sists of a to­tal of 149 high-pow­er light sources, each of which is a sev­en-kilo­watt xenon short-arc lamp, as used in cin­e­ma pro­jec­tors. Each source can be in­di­vid­u­al­ly con­trolled, which al­lows var­i­ous con­fig­u­ra­tions and tem­per­a­tures in the fo­cal point – even in three si­mul­ta­ne­ous ex­per­i­ments.

Testing performance and durability of reflectors and receivers

Test­ing per­for­mance and dura­bil­i­ty of re­flec­tors and re­ceivers

March 6, 2014  Re­searchers at the DLR In­sti­tute of So­lar Re­search test the re­ceiv­er per­for­mance at the QUARZ Cen­ter in Cologne, in­ves­ti­gat­ing the per­cent­age of sun­light that the tubes con­vert in­to heat . The tests are car­ried in the El­liRec test stand.

July 4, 2011  At the Jülich site, set up on an area cov­er­ing about eight hectares, are 2153 mov­ing mir­rors that con­cen­trate the so­lar ra­di­a­tion on­to a re­ceiv­er atop the 60-me­tre tow­er.

DLR solar furnace in Cologne

DLR so­lar fur­nace in Cologne

September 8, 2011  A 57 square me­tre mir­ror col­lects sun­light and di­rects it to­wards the facetted mir­rors (left in the pic­ture). These mir­rors con­cen­trate the in­com­ing ra­di­a­tion up to around 5200 times and di­rect it to the re­search lab­o­ra­to­ry of the Cologne so­lar fur­nace (the beam of light can be seen on the right of the im­age).

Hydrogen production using solar energy

Hy­dro­gen pro­duc­tion us­ing so­lar en­er­gy

November 29, 2017  DLR sci­en­tists and their re­search part­ners test and de­vel­op new ways to pro­duce hy­dro­gen us­ing so­lar en­er­gy at the Platafor­ma So­lar de Almería.

Hydrogen from wind and solar energy

Hy­dro­gen from wind and so­lar en­er­gy

January 22, 2014  Pro­ton Ex­change Mem­brane (PEM) elec­trol­y­sers can go from start-up to full load op­er­a­tion with­in min­utes and thus adapt to the fluc­tu­at­ing sup­ply of wind and so­lar pow­er.

Flameless combustion

Flame­less com­bus­tion

April 4, 2019  Ni­tro­gen ox­ides play an un­pleas­ant role dur­ing the com­bus­tion of fos­sil fu­els. They are re­spon­si­ble for acid rain and are al­so harm­ful to the res­pi­ra­to­ry tract. DLR re­searchers have been able to demon­strate that the prin­ci­ple of flame­less com­bus­tion (‘FLOX®’, or FLame­less OX­i­da­tion) in typ­i­cal gas tur­bine con­di­tions promis­es re­li­able com­bus­tion in pow­er plants with low ni­tro­gen ox­ides emis­sions.

Direct solar steam generation and storage

Di­rect so­lar steam gen­er­a­tion and stor­age

April 5, 2019  The Ger­man Aerospace Cen­ter (DLR) and En­de­sa test di­rect so­lar steam gen­er­a­tion and en­er­gy stor­age in this pi­lot plant in Car­bon­eras, lo­cat­ed in south­ern Spain. In this type of so­lar pow­er plant, steam is pro­duced di­rect­ly from con­cen­trat­ed so­lar ra­di­a­tion and used to drive a gen­er­a­tor. The high­light of this fa­cil­i­ty is a new sys­tem that ef­fi­cient­ly stores en­er­gy, both as sen­si­ble and la­tent heat. The stored en­er­gy can be used to gen­er­ate elec­tric­i­ty even at night.

The energy system of the future must be sustainable. Ideally, it should not generate emissions that affect the climate or be at risk of major malfunctions or hazardous environmental impact. Energy should be economical and socially acceptable and its provision should be reliable. Required highly efficient technologies to produce and use this energy are the focus of the DLR energy research.
