A new era of energy provided by renewables may be close at hand, thanks to research begun at the Joint Center for Energy Storage Research (JCESR), a U.S. Department of Energy (DOE) Energy Innovation Hub led by DOE s Argonne National Laboratory, and continued at spinoff company Form Energy.
The challenge JCESR addressed is long duration storage stabilizing a renewable grid against several consecutive days of calm or overcast days when wind and solar generation is absent or severely limited. Today s lithium-ion batteries can discharge at full power for 4-6 hours, enough to stabilize against most intra-day variations due to passing clouds or fluctuating winds, or to extend solar electricity a few hours past sunset to serve the evening demand peak. A full day or consecutive days of windless or overcast weather is stabilized by natural gas p

As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space or weight, one of the more promising technologies being studied is lithium-ion batteries that use a solid electrolyte material between the two electrodes, rather than the typical liquid.
