'Battery grid storage solutions, which have seen significant growth in deployments in the past decade, have projected 2020 costs for fully installed 100 MW, 10-hour battery systems of: lithium-ion LFP ($356/kWh), lead-acid ($356/kWh), lithium-ion NMC ($366/kWh), and vanadium RFB ($399/kWh). For lithium-ion and lead-acid technologies at this scale, the direct current (DC) storage block accounts for nearly 40% of the total installed costs.'
$33/kwh difference to Li. Next year will hopefully be a transformational year for VRFB's. Almost on par cost with with Li, but with the additional safety and life-span we all know about.
