ABSTRACT
Batteries for electricity storage have been the weak point of the whole renewable generation proposition. There is a reliable battery storage technology that allows energy to be locally generated at all hours of day and night by sun and wind, and stored conveniently. The zero-fossil energy development powerbank battery can store around 0.5 kWh and be easily picked up, traded and exchanged so that it can be rented or purchased. One standard solar panel producing a maximum of 250 W can easily charge one of the batteries in one day in most climates. The argument that batteries are toxic and the materials used on the larger-scale will cause environmental degradation and resource depletion needs to be challenged head-on. A combination of eight transport-grade exchangeable batteries and one static 4 kWh aqueous ion salt-water and carbon battery would make almost any household independent of fossil fuels.
