Scientists at the Fraunhofer Institute have developed a method to transform harmful CO2 into valuable resources. Using a tall tower fitted with mirrors, they create sustainable synthetic fuels from water, CO2, and sunlight. These fuels can be utilized to power vehicles like cars and planes, aiding in the reduction of our reliance on fossil fuels.
Project Overview
This initiative, named Material Advancements for Solar Fuels Technology (MAfoS), is based at the Centre for High Temperature Lightweight Structures (HTL) within the Fraunhofer Institute for Silicate Research (ISC) in Germany. The goal is to establish the first industrial plant that converts solar energy into fuel.
Currently, there is a pilot facility located in the solar tower of the German Aerospace Centre (DLR) in Jülich, which is managed by the Swiss partner, Synhelion. This solar-to-fuel plant harnesses solar energy to synthesize fuels from water and carbon dioxide (or methane).
Commitment to Renewable Energy
"We have always aimed to broaden our efforts in renewable energy, energy efficiency, and power-to-X and power-to-fuel, alongside our traditional Fraunhofer HTL focus on high-temperature coatings, materials, and ceramic fibers. This project showcases our capability as a strong collaborative partner for small to medium enterprises, particularly in this sector, due to our market orientation and specialized knowledge," stated Arne Rüdinger, Head of the Ceramic Fibers Department at Fraunhofer HTL.
The Jülich facility features a solar tower where mirrors concentrate sunlight to generate heat. This heat is then utilized to convert the initial materials in a reactor at elevated temperatures and pressures, resulting in the production of fuels, such as kerosene. A significant challenge of this project involves developing specific materials that can endure extreme temperatures of up to 1,500 degrees Celsius along with water vapor.
Importance of Research
"It is fantastic that our research can play a crucial role in lowering CO2 emissions, contributing to the sustainable transformation of society," remarked Jonathan Maier, the project manager for MAfoS.
