Widely ignored, although gaining attention, is China’s strategic positioning as a crucial gatekeeper to several key “green” technologies, including battery energy storage to support electric vehicles (EVs)—specifically, battery electric vehicles (BEVs)—along with stationary storage for power grids.

Despite the much-vaunted megatrend involving the global electrification drive and shift to renewable energy , the most ambitious pledges by Big Oil to pursue net-zero agendas remain weak at best. Let this sink in: In 2018, Big Oil spent less than 1% of its combined budget on green energy projects.

Performance comparison between Li–I SFB and conventional Li–I batteries: (a) a typical depleted charging and discharging voltage profile; (b) the initial charging voltages for 25 cycles. Aqueous flow batteries have attracted significant interest because they could theoretically provide affordable power grid-level energy storage someday.
