Pacific Northwest National Laboratory (PNNL) has developed a zinc-polyiodide flow battery with a high energy density that will ensure that the power grid can keep the lights on in large cities. Page 1 of 1 The PNNL zinc-polyiodide flow battery reduces the battery's size and cost and makes it well suited to store energy in densely populated cities and provides a battery that packs far more energy than any other battery of its kind and size.
Can flow battery advance lower urban power costs? - Electronics Eetimes
Australia has some of the highest electricity prices in the world due to an overbuild of network infrastructure. Could falling battery costs cause increasing numbers of customers to abandon the system altogether? Solar power installers in the country say the cost of batteries is the only thing holding back more widespread consumer grid defection in the residential sector. Australia is already in the midst of a rooftop solar boom as grid customers look to offset the rising cost of utility power. Almost one-fifth of Australian households now use solar panels for electricity or hot water, tempted by three- to four-year payback times and national rebates that reduce the upfront cost of a PV system.
