Solar Fuels

From sunlight to fuel

Duration: 01.1.2019-31.12.2021

As part of the “Energy Transition in Traffic” research initiative, the “SolarFuels” project is working on the extent to which the production and use of fuels from solar thermal production processes as drop-in fuels can contribute to a rapid reduction in fossil CO2 emissions from transport. The entire chain from solar fuel production from water and CO2 to the consumer side, the engine combustion process, is examined and examined.

MenaFuels

Roadmaps for the production of sustainable synthetic fuels in the MENA (*) area for the decarbonisation of traffic in Germany

Duration: 01.10.2018 – 31.03.2022

MENA-Fuels aims to show the strengths and weaknesses, opportunities and obstacles as well as the development potential of relevant synthetic fuels. The fuels rated as promising are analyzed with a view to their embedding in and repercussions on the energy system. * MENA: Middle-East and North Africa (North Africa and Middle East)

Future Fuels

DLR interdisciplinary project

Duration: 01.01.2018 – 31.12.2021

The growing share of renewable energies in Germany not only requires additional large capacities in the area of electricity and supply networks, but also innovative solutions for energy storage and transport. Synfuels are expected to play a key role as energy carrier for the transport sector and as energy buffer for the integration of large amounts of renewable energy into the grid. In the project Future Fuels 2, the production of synthetic fuels through solarthermal procedures (Solar Fuels) and electrolysis (Power-to-Fuel) is being analysed. Sub-processes are being developed and processes are being demonstrated.

On-demand solar power production using sulphur storage technology

Duration: 01.08.2018 – 31.12.2021

In cooperation with the EU-project PEGASUS, a sulphur storage cycle is developed, which enables solar electricity production regardless of daily and seasonal fluctuation of solar radiation. This process is based on a storage system in which sulphur is produced during solar operation. This sulphur can then be used for continuous power generation.

PEGASUS

Renewable power generation by a solar-driven sulphur storage cycle

Duration: 1.11.2016 - 30.06.2021

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.

TRAKSOL

Development and qualification of solar receivers based on transparent ceramics for solar chemical processes
One of the central challenges in the design of solar receivers ist he availability of suitable materials for construction. This is especially applicable to solar receivers for chemical processes. For instance the evaporation and decomposition of sulfuric acid, where chemical stability is demanding. In the Project TRAKSOL, the application of transparent ceramics in solar receivers is investigated and demonstrated in lab scale. Through this, a relevant improvement in receiver efficiency is expected.

CALyPSOL

Calcium oxide looping through Solar energy
Calcium oxid looping means the transformation of lime (CaO) into limestone (CaCO₃) and vice versa. It is a conventional, energy intensive process for the sequestration of carbon dioxide (CO₂) from industrial exhaust gases. CALyPSOL tries to operate this process with solar energy. A reactor for the calcination (the endothermic transformation of CaCO₃ into CaO und CO₂) will be developed for operation with concentrated solar radiation. The complete process will be demonstrated in the High-Flux solar furnace of DLR in Köln-Porz.

Silicone oils as heat transfer media
Solar thermal power plants play a very important role in the energy transition in sunny regions of the world, as in combination with a heat storage system they can also deliver electricity after sunset. The efficiency of solar parabolic trough power plants is largely determined by the efficiency of the solar field. Better utilization of the incident solar radiation is possible, for example with a higher maximum temperature of the heat transfer oil, which circulates in the absorber tubes and absorbs the solar radiation. A consortium of research and industry led by the German Aerospace Center (DLR) is currently demonstrating the suitability of silicone-based heat transfer oils as part of various funding projects.
