Solar already provides peak power at peak load, and through distribution is resilient, and that plus ever-decreasing prices will drive solar deployments up exponentially for a decade or so yet. If we add an inexpensive metal-free battery, solar will take over even faster. And that’s what Harvard’s School of Engineering and Applied Sciences has just published as a discovery.

Harvard SEAS PR of 8 January 2014, Organic mega flow battery promises breakthrough for renewable energy: Harvard technology could economically store energy for use when the wind doesn’t blow and the sun doesn’t shine,

The paper reports a metal-free flow battery that relies on the electrochemistry of naturally abundant, inexpensive, small organic (carbon-based) molecules called quinones, which are similar to molecules that store energy in plants and animals.

And much less expensive, reported CBC News 9 January 2014, Continue reading →
