Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Sandia researchers have developed a new family of electrochemically reversible, metal-based ionic liquid (MetILs) that could lead to non-aqueous redox (reducing-oxidizing) flow-battery energy storage systems ( earlier post ) able to cost-effectively store three times more energy than today’s batteries. —Imre Gyuk.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

That is about three times as much power per square centimeter as other membrane-less system—a power density that is an order of magnitude higher than that of many lithium-ion batteries and other commercial and experimental energy-storage systems. One such permutation is the hydrogen bromine flow battery.

Fossil Fuels Renewable Energy and EV Modern Life

Setec Powerr

A critical issue in decarbonization will also be the role of the electrical grid itself. Wind and solar farms are alternatives to fossil fuel-fired power plants. With current technology, these new forms of power plants require a great deal of land along with adequate transmission lines. We need off-grid and on-grid solutions.

Lessons from a year with solar power

EV Info

Is controls all aspects of power generation and use. Your power comes from the grid as 240 Volts AC. The panels generate DC current that varies with the solar power. Battery Pack: PylonTech Battery Storage . Initially our Electricity was provided by Scottish Power. Octopus – The clever bit.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

The future grid will face significant challenges by providing clean power from intermittent resources to a much more dynamic load. To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. —Yang et al. Credit: ACS, Yang et al. Click to enlarge.

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

In April, Axion Power International Inc received an order from Norfolk Southern Corp (NS) for PbC lead-carbon batteries for use in an all-battery-powered switcher locomotive. The proposed system uses a very small starter battery, the sole function of which is to start the engine. Source: NS. Click to enlarge.

Small long-term evaluation program, including modeling of vehicle-to-grid building benefits and economics, begun with Southern California Edison, joined by EPRI, other utilities, US DOE. Batteries not ready. The F6 DM uses ferrous batteries, with no lithium content, that BYD says are high-energy density and low cost.
