The clean energy company evolved from the Swiss Federal Institute of Technology (ETH Zurich) in 2016 to decarbonize the transportation sector. Synhelion is a global pioneer in the field of carbon-neutral solar fuels. Sandia Labs has major research and development responsibilities in nuclear deterrence, global security, defense, energy technologies and economic competitiveness, with main facilities in Albuquerque, New Mexico, and Livermore, California. Department of Energy’s National Nuclear Security Administration. Sandia National Laboratories is a multimission laboratory operated by National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Replacing fossil fuels entirely with solar energy is a game-changer in the industry's efforts to achieve carbon neutrality. Fossil fuels are typically used to heat the kiln and are responsible for approximately 40% of the direct CO 2 emissions of the process. Successful adoption of this technology in cement manufacturing will not only allow for 100% replacement of fossil fuels but also result in a more efficient and lower-cost carbon capture process when compared to the current state-of-the-art technologies.Ĭlinker is produced by fusing limestone, clay, and other materials in a rotary kiln at temperatures nearing 1,500☌. The team will assess the conditions to maximize heat transfer to the raw cement mix. The project will investigate methods to reduce carbon dioxide emissions, lower process temperatures, and increase the efficiency of clinker formation using solar energy. We are proud of contributing to this goal." This solution can have a huge impact on the industry and will help to pave the way towards net-zero. Gianluca Ambrosetti, CEO and Co-Founder of Synhelion, added: "The project offers us the opportunity to use our sustainable technology to support the decarbonization of energy-intensive cement clinker production. "This project will advance our understanding of how to use concentrating solar technology to gather and deliver the heat to existing cement production facilities and will have crosscutting relevance to other ore processing industries such as refractory, ceramics, and battery production." "Few renewable technologies are capable of generating heat at the temperatures needed to process raw cement feedstock," said Nathan Schroeder, Sandia researcher and principal investigator for the Solar MEAD project. "Achieving our net zero carbon goal by 2050 will require relentless innovation such as this to discover and scale breakthrough technologies." "Cement produced with solar energy is an exciting technology with tremendous potential to reduce the carbon footprint of cement production," said Fernando A. Synhelion's breakthrough technology delivers high-temperature process heat beyond 1,500 degrees Celsius – sufficient heat to produce clinker without using fossil fuels. Sandia Laboratories will contribute unique research facilities as part of the National Solar Thermal Test Facility, and subject matter expertise to help accelerate the adaptation of the technology to cement manufacturing. CEMEX and Synhelion have been collaborating to introduce CST in the cement production process, achieving the first successful laboratory-scale demonstrative pilot in 2022 by producing the first-ever solar clinker. Solar MEAD aims to replace the use of fossil fuels with concentrated solar thermal ("CST") energy in clinker production, the key component in cement.
