Harvard flow battey could help bolster wind and solar

Flow batteries – more akin to fuel cells, really – are getting increasing attention as researchers press to meet a need for energy storage brought on by the rise of intermittent renewable sources like solar and wind.

New flow battery could enable cheaper, more efficient energy storage

MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.
