Yonsei University Develops Biochar-Clay Composite for Energy Efficient Cooling
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.

Researchers at Yonsei University in South Korea created a composite material that stores and releases heat using paraffin by combining spruce wood biochar with montmorillonite clay and liquid hexadecane. The new composite, EMBC16, showed a 223% increase in energy storage capacity and improved thermal conductivity by 78%.
Simulations indicated a 54% reduction in annual cooling energy consumption for buildings using EMBC16 compared to bulk paraffin. The researchers aim to enhance sustainability by replacing synthetic surfactants with bio-based alternatives for production.
