With the UN Climate Change Conference underway, hear from three Unreasonable Impact entrepreneurs - ZincFive, ChargerHelp and e-Zinc - strengthening the backbone of clean power.


Unlike lithium-ion technologies, which store only a few hours of power, e-Zinc’s proprietary zinc-based solution can store multiple days of clean energy capacity, keeping power flowing even when demand surges. “A lot of electrochemical technologies exchange ions between electrodes. What we do is store energy in physically free metal,” explains Larsen. “It’s turning electrochemistry on its head.”
