The increasing environmental concerns triggered by burning fossil fuels have caused a pivot to green and clean energy sources such as wind and solar. Driven by the UN’s SDGs and European Green Deal, this decade is witnessing the exploration of sustainable alternatives to fossil fuel energy. Green technologies, however, require an energy storage solution to reach their full potential. Electrochemical energy storage devices such as batteries pave way for climate neutral energy programs. Batteries come in every shape and size these days as they have different chemistries, but they must be certainly safe, durable, and efficient. Likewise, significant improvements are required for batteries in terms of sustainable materials inputs along the battery value chain. Sweet batteries are commonly known as sugar biobatteries, which are net-zero energy storage procedures, are a precious power substitute for battery making and its bio-clearance. In this study, we discussed the recent progress in bio-based batteries and their emergence towards next-generation green energy storage technologies for a sustainable energy future. The emerging technical feasibilities, challenges, and solutions for the long-term use of sweet batteries are also explored. The sugar biobatteries could achieve better (up to 10x) energy density with improved charging as well as recharging capabilities compared to traditional chemical batteries.
