Electrovaya Inc. launched its lithium-ion energy storage system for home usage. The battery stores power from the grid or from solar panels and stores it for later household use.
For consumers subject to time-of-use charges, the EnergyBlock can be used to store off-peak power to be used later during peak times, lowering the amount of peak-rate costs for the user. In some regions, utilities occasionally provide negative pricing to dump excess power when demand is very low, so users may actually be paid to store energy. The EnergyBlock can also store energy directly from solar panels, power in remote locations and emergency power.
Systems are available in sizes from 3 kWh – 20 kWh. The ideal size for most households is 7 kWh, suggests Electrovaya, which provides several hours of power for the typical consumer.
We’re expecting this product to be very popular in places like Germany and Japan as they move away from nuclear power towards sustainable alternative energy. Asia is another key market, with an incomplete electric grid, and we believe there will be a large market opportunity in North America, where we’re paying twice as much for peak power and need a way to store cheap off-peak power.—Dr. Sankar Das Gupta, CEO of Electrovaya
