With the generation cost of energy from wind and PV solar moving rapidly close to grid parity (i.e., when an alternative energy source can generate power at a levelised cost of electricity (LCOE) that is less than, or equal to, the price of purchasing power from the electricity grid), better energy storage devices with higher round-trip efficiency and longer life have become essential. Although traditional lead–acid batteries have a round-trip efficiency of only 80 to 85%, the technology is still widely used for energy storage systems as it is less expensive than other chemistries and is almost completely recycleable. The low efficiency is due to the energy consumed in charging batteries fully to avoid irreversible sulfation. Firefly’s Microcell Carbon Foam (MCF) technology, which was invented in the R&D Labs of CATERPILLAR, almost eliminates all the limitations of traditional lead–acid batteries. The advanced battery has a 3-dimensional architecture perfected by Firefly ― Carbon Foam grids are impregnated with a slurry of active material. The structure redistributes the electrolyte solution from the small separator reservoir of a conventional battery to the highly porous foam plates. Consequently, each Microcell has its full complement of active material and sulfuric acid and thereby increases the efficiency of the lead–acid chemistry. A round-trip efficiency of over 90% is achieved under partial state-of-charge duty, together with a 2 to 3 times increase in service life compared with tradition technology. Accordingly, MCF batteries are particularly suitable for renewable energy storage in remote locations and on islands. For example, in January 2017 Firefly supplied 7.1 MWh of MCF Batteries to the Miyazaki PV Project on Kyushu Island, Japan.
