DOE energy innovation hub backs two key future battery technologies

Nick Flaherty for EE Times:  After four years of evaluation, the Joint Center for Energy Storage Research (Chicago, IL) is backing two key technologies for the future of battery systems.

The Center was set up four years ago with a five year remit to explore new battery technology for transportation and the electricity grid that, when scaled to commercial production, are capable of delivering five times the energy density at one-fifth the cost of commercial batteries available in 2011.

The Center has investigated 1,500 compounds for electrodes and 21,000 organic molecules relevant for liquid electrolytes as well as filing 52 invention disclosures and 27 patent applications, says director George Crabtree. Five techno-economic models created by JCESR for designing virtual batteries on the computer are being used to evaluate the best pathways for beyond-lithium-ion systems to reach 400 watt hours per kilogram (400 Wh/kg) and $100 per kilowatt hour ($100/kWh).  Cont'd...

Flow Batteries in Cars?

Flow battery technology is immature. There is everything to play for and although pumping liquids from reservoirs does not sound compact or reliable in a car but who knows? Watch this space.

Is 2016 The Turning Point For Energy Storage?

Michael McDonald for  In the future, when investors look back at the year that represented the turning point for clean energy, 2016 may be it. The industry overall is growing at a breath-taking pace, but perhaps not for the reason that some investors think. Energy storage rather than solar power and wind power are the real factors that are driving a revolution across the electrical power industry.

Energy storage changes the equation, not only in the renewables space, but in the conventional utility space as well. The concepts of spin/non-spin reserve costs, peaker prices, and a variety of other conventional concerns for utilities, lose meaning in the context of efficient and cost-effective energy storage. While energy storage was available previously, it’s only today that costs are coming down substantially. Tesla’s economies of scale on battery storage are well-known, but small start-ups like Orison are finding ways to lower costs in innovative ways as well. The graphic below from a recent EPRI presentation highlights the role that multiple layers of costs savings can play in creating economical battery storage.  Cont'd...

The "Redox" Principle

The energy density of the nanoFlowcell® is currently 20 times higher than that of a lead accumulator. This means the stored energy provides a range 20 times higher than with a battery of the same weight.

ViZn Energy Systems' 2MW Zinc-Iron Redox Flow Battery System Selected by Hecate Energy for Ontario IESO Project

System to be largest commissioned flow battery installation in North America and Europe

Vanadium Flow Batteries for Global Academy of Technology (GAT) College

By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.
