The year 2016 will probably be remembered as the point at which energy storage began to take off in earnest.
Projects came thick and fast as interest in storage extended quickly beyond early hotspots such as California and Germany.
We saw grid-scale storage playing a starring role in the UK’s frequency response market, while battery makers jostled for position in an increasingly buoyant Australian consumer market. And that was just a couple of examples.
Almost every major energy market in Asia, Europe and North America had a storage story to tell. But which were the ones that caught your eye? Here’s a rundown of our most popular headlines from 2016. Read more →

Kreisel Electric has become the latest battery vendor to take on the Tesla Powerwall with the launch of a residential energy storage product today.
The Austrian industrial firm is looking to improve on Tesla’s trailblazing battery pack with a system that uses the same 18650-size lithium-ion cells, with a few significant manufacturing improvements.
Critically, Kreisel uses a laser system to solder connections to each cell in the battery. This is in contrast to traditional manufacturing processes where welding is employed.
The heat generated from the welding process damages cells before they are even used, said Christian Schlögl, head of business development. “With our laser technology we don’t destroy the cell,” he told Energy Storage Report.
The laser manufacturing process helps make sure all of the 8,000 or so cells in each battery have the same capacity and voltage once connected, so there is no need to balance them afterwards. Read more →
