Concept of the highly efficient acetylene synthesis process from CO2 using two-step electrolysis
The innovative process, which does not require fossil fuels, can pave the way for a sustainable acetylene-based industry.

Researchers, including Yuta Suzuki, Assistant Professor at the Harris Science Research Institute, have developed a novel method for synthesizing acetylene from carbon dioxide without using fossil fuels.

Conventional acetylene synthesis methods rely on fossil fuels. A new process is required for its sustainable synthesis to reduce its carbon footprint. In a new study, researchers from Doshisha University and Daikin Industries Ltd developed a novel method for synthesizing acetylene from carbon dioxide via calcium carbide without using fossil fuels. This innovative process can contribute to realizing a sustainable acetylene-based industry.
