A pilot scheme in Brooklyn is giving businesses batteries to form an electricity storage network – part of a growing number of innovative DIY energy ideas around the world

In the back of Black Seed Bagels in northern Brooklyn is a giant catering kitchen filled with industrial-size containers of condiments and freezers full of dough. A tall, silver electric oven named the Baconator stands in a far corner, cooking thousands of pounds of meat every week to accompany Black Seed’s hand-rolled, wood-fired bagels. The Baconator is connected to a battery the size of a carry-on suitcase, which is plugged into the wall.

While the morning rush is under way, the 2.8-kilowatt-hour battery can directly power the commercial oven to reduce the company’s reliance on the electric grid, Noah Bernamoff, Black Seed’s co-owner, explained recently at the company’s Bushwick shop. Two more batteries are paired with energy-intensive refrigerators in the front.
