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

To be successful, systems will need to evolve—in some cases, considerably—to compete financially with the cost of natural gas production. To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. Click to enlarge. In their study, Yang et al.
