Pressing environmental challenges require focused research on sustainable solutions in the domains of energy, water, food, land, and climate. The pigment eumelanin has recently been positioned as a promising candidate for solving issues health, sensors, energy storage. However, low solubility aqueous solvents, difficult film processibility, high cost have hindered material from wide deployment. Here, we propose melanin extracted black soldier fly, Hermetia illucens (Mel-BSF), alternative preparation organic electrodes storage applications. Mel-BSF displays pseudocapacitive behaviour with potential window, good electrochemical stability, higher maximum capacity (91.8 mAh g−1) compared to synthetic (17.3 working electrode zinc-ion hybrid capacitors using an ionic liquid electrolyte. Structural surface investigations reveal that additional aliphatic compounds, potentially lipids present after refinement, significantly increase stability redox centre availability. Eumelanin is use applications but limitations hindering its usage. fly used prepare performance than capacitor
