Vitamin B2 And Sugar Power A Safer Home Flow Battery Design
If engineering advances push oxygen reduction and light stability further, a glucose flow battery could serve as long duration storage fed by inexpensive biomass derived sugar or
RICHLAND, Wash.— A common food and medicine additive has shown it can boost the capacity and longevity of a next-generation flow battery design in a record-setting experiment.
If they are scaled up to the size of a football field or more, flow batteries can serve as backup generators for the electric grid. Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources.
Flow batteries differ from solid-state batteries in that they have two external supply tanks of liquid constantly circulating through them to supply the electrolyte, which is like the “blood supply” for the system. The larger the electrolyte supply tank, the more energy the flow battery can store.
Flow batteries haven't gone mainstream, yet, but they are slowly edging into the market. Lithium-ion batteries are still the gold standard for energy storage systems that can be recharged over and over again. Lithium-ion technology is a good fit for all sorts of devices, from smart phones to electric vehicles.
