Trace amounts of renewable surfactants enable rapid and high-density methane storage in clathrate hydrates: Sustainable alternatives to synthetic promoters

Key Points

• The central aim is to explore the effectiveness of renewable surfactants in enhancing methane storage in clathrate hydrates.
• Examined six anionic renewable surfactants with different counterions
• Compared their effects on methane storage capacity in clathrate hydrates
• Analyzed the environmental impact of using renewable versus synthetic surfactants
• Renewable surfactants significantly increased methane storage density
• The most effective surfactant exhibited rapid clathrate formation
• Results suggest a sustainable alternative to traditional synthetic promoters for gas storage
