Renewable power generation by a solar-driven sulphur storage cycle
Effective and economic long-term storage of solar energy is crucial in order to fully replace fossil power plants by renewable sources. In this context, the European project PEGASUS investigates a novel power cycle for renewable electricity production combining a concentrating solar power (CSP) plant with a sulphur storage system for 24 hours baseload operation.
Sustainable fertilizer production from sun, air and water
Fertilizer production today comes along with immense CO2 emissions. Large amounts of natural gas are required to produce the important fertilizer base chemical ammonia. In Düsol, we modify the production in such a way, that no natural gas is used anymore. Solar-fired chemical processes generate the precursor components of ammonia solely from water and air.
Solar energy for chemical industry: Indirectly solar heated reformer for the production of methanol from CO2 and natural gas
The conventional production of synthesis gas (Syngas), which is an intermediate product for a variety of chemical products, such as Methanol, causes significant CO2 emissions. When utilizing solar energy, the emissions can be greatly reduced. Recycling of CO2 in the process further reduces the emissions.
Innovative parabolic trough collectors made from concrete
In modern parbolic-trough power plants, the cost of the collector field is about 50% of the entire investment cost. The cost-reduction potential for the common steel structures is largely exhausted. Using concrete as the main structural material offers comparatively low material and manufacturing costs, as well as further potential for cost-reduction.
Bringing thermochemical water splitting to the next level
In this visionary project, major engineering challenges are tackled, which on paper promise great efficiency improvements. Together with Sandia National Labs from the US, we develop a test facility to show that irradiating particles beyond 1450 °C at reduced pressure is feasible.
Development of the next generation molten salt power tower
The project PreFlexMS includes tasks within research and development in different disciplines, in order to increase the performance of solarthermal power towers by using liquid salt as heat transfer medium.
Solarthermal electricity generation in combination with biomass
In the frame of the EU Project REELCOOP a solar thermal power plant in the small range is being investigated in combination with biomass.
Retrofit of a parabolic trough solar field with a solar tower
The project Resol (Retrofitting Solarthermal Power Plants) is a cooperation of MAN Diesel and Turbo SE in Oberhausen, the Solar Institute of Jülich and DLR. The objective of the project is to analyze the possibilities to reduce levelized electricity costs by adding solar towers to existing parabolic trough plants within a package of retrofitting measures.
Solar aluminium smelting in a directly irradiated rotary kiln
In this German - South African cooperation, we strive to Elaborate a sustainable way to run the energy intensive Aluminium smelting process.
Direct integration of solar steam into fossil steam generator
In the project SolSteam the Institute of Solar Research develops and investigates concepts for the direct integration of solar steam into industrial steam systems in collaboration with its partner Industrial Solar.
Virtual Institute SolarSynGas
Thermochemical Research for CO
-neutral Renewable Fuels
The Virtual Institute SolarSynGas pursues the long-term goal to produce CO
-neutral renewable fuels efficiently and economically via a thermo-chemical route. Behind SolarSynGas are the DLR Institutes of Solar Research and Materials Research and the three universities KIT Karlsruhe, TU Clausthal and ETH Zurich.
