Researchers at Yonsei University have developed a biochar-clay composite, EMBC16, which significantly enhances energy storage and thermal conductivity by combining spruce wood biochar with montmorillonite clay and liquid hexadecane. This innovative material demonstrated a 223% increase in energy storage capacity and could reduce annual cooling energy consumption in buildings by 54% compared to traditional bulk paraffin. The team also aims to improve sustainability by using bio-based alternatives to synthetic surfactants in its production.
