Bio Based Batteries

The expanding use of electrical power generated from wind turbines and solar photovoltaic plants is enabled by the decreasing cost of electrical energy from sun and wind. With the advent of electrical energy from the intermittent solar and wind energy resources comes the requirement that electricity must be stored for use over time. The huge demand for materials for such storage systems will require a considerable energy input in extraction, processing and materials formulation, and new and sustainable electrochemical systems need to be developed. Storing electrical energy in bio based batteries is one of the options for handling the rapid expansion of renewable and variable electrical energy generated in wind turbines and in solar photovoltaic systems, from small to large. With projected needs for storage at 300 GWh for the coming decade, there are many niches for new technologies and possibilities. A supply line of materials for energy storage materials could be ultimately based on photosynthesis, in the form of materials derived from plants. Redox activity is possible in lignin, humic acid, and polyphenolic macromolecules, sometimes by electrochemical activation of redox groups.

Automated summary

The increasing use of electricity generated from solar and wind energy has led to a growing demand for energy storage. This demand for materials for storage systems will require considerable energy input, and sustainable electrochemical systems need to be developed to address this issue. Storing electrical energy in bio-based batteries is seen as one option for handling the rapid expansion of renewable energy generated from wind turbines and solar photovoltaic systems.
