The design and synthesis of highly active and long‐term durable carbon‐based electrocatalysts with inexpensive raw materials and an environment‐friendly method for many renewable energy conversion and storage technologies remain a major challenge. Herein, we demonstrate a novel synthesis of nitrogen‐doped hierarchically porous carbon nanomeshes. This is the first report of using a green fermentation method to introduce nitrogen sources with grape skins as a single precursor which are a green and highly economical biomass waste globally generated at over 8 million tons per year. The resultant material has a high BET surface area (1029.41 m 2 g −1 ), abundant hierarchical porosity and shows the impressive electrocatalytic performance, durability and excellent methanol tolerance in pH‐universal media for the oxygen reduction reaction (ORR) and alkaline media for the oxygen evolution reaction (OER). This low‐cost fermentation approach provides a brief pathway to prepare outstanding N‐doped carbon‐based electrocatalysts straightforward from waste biomass.
