While renewable energy sources are sustainable, their intermittent nature necessitates the development of efficient energy storage devices to ensure uninterrupted power supply and optimal energy utilization. Electrochemical energy storage devices are promising for sustainable energy. Traditionally, carbon electrode materials for these devices come from non-renewable sources. However, using biomass and biomass–coal blends can help substitute fossil fuels, reducing environmental impact. Recent advancements in carbon materials have achieved specific surface areas of over 2500 m<sup>2</sup>/g, resulting in supercapacitor capacitances of 250–350 F/g and cycling stability exceeding 10,000 cycles with < 5% capacity loss. In lithium-ion batteries, biomass-based anodes deliver 400–600 mA h/g, outperforming graphite. Doped carbon materials enhance charge-transfer efficiency by 20–30%, while CO₂ emissions from production are reduced by 40–60%. With 50–70% lower costs than fossil-based alternatives, biomass-derived carbons present a viable pathway for scalable, eco-friendly energy storage solutions, accelerating the transition toward sustainable energy systems. Overall, this work highlights the influence of carbon materials on the electrochemical properties and hydrogen storage capacity of biomass-based carbon materials.

However, the base metal of the structural material may also undergo corrosion, increasing the concentration of metal ions, such as ferrous ions, in the decontamination solution. The increased concentration of metal ions leads to an increased use of cation exchange resins in wastewater treatment, thereby increasing the amount of secondary wastes.
