The past 12 months has reshaped the Flow Battery Electrode Felt industry trends, as major players lock in partnerships and investors pour capital into scale‑up projects. In March, EnerGraft and Sungrow Power announced a joint‑development agreement to co‑engineer a high‑conductivity carbon felt optimized for vanadium redox systems, targeting European utility pilots. In July, AquaVolt completed the acquisition of CarbonFlex, consolidating the fragmented felt supplier landscape and expanding its North‑American footprint. September saw the launch of NeoFelt‑X, a low‑pressure‑drop electrode that claims 15 % higher round‑trip efficiency, while the U.S. Department of Energy’s revised Energy Storage Grant guidelines now prioritize recycled‑material felts, prompting several manufacturers to revise their sourcing strategies. Meanwhile, a $120 million Series C round led by GreenTech Capital enabled VoltMaterials to double its production line in Shanghai, aligning with the surge in corporate renewable‑energy commitments. Additionally, the EU’s revised Renewable Energy Directive, effective January 2025, classifies recycled carbon felts as eligible grid‑scale storage assets, prompting early certification efforts by European manufacturers.
