A newly unveiled company led by battery and tech industry vets says it's cracked the code that could enable much faster charging of the kind of lithium-ion batteries already used in electric vehicles — providing roughly 120 miles of range in just 5 minutes.

Why it matters: If their tech works as envisioned, the firm GBatteries could help EVs go mainstream by toppling a major barrier to ultra-fast charging: electrode damage that degrades the life expectancy of batteries.

Solar storage technology is having its time in the sun

Hawaiian Electric Company just submitted to state regulators seven massive new solar-plus-storage contracts. If built, these would add more than 260 megawatts of solar and, more significantly, over 1,000 megawatt-hours of storage to the Hawaiian grid — more than the total cumulative amount of energy storage deployed across the U.S. between 2013 and 2017.

Why it matters: Solar plus storage is having a breakout moment. The technology allows the power generated by intermittent renewables to be better matched to times when the grid needs it most, which is critical for clean energy growth to continue. It also means that renewables may come to compete more directly with natural gas in some markets, rather than requiring more gas to balance their intermittency, as has been the case so far.
