Batteries from electric bus route 55 in Gothenburg, Sweden are being used for solar energy storage in a second-life application. The reuse and recycling of batteries is a key issue as increasing numbers of cities plan transition to electrically powered transport.
Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al. Background.
The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Some companies have landed on thermal storage.
V2G returns the energy stored in EV batteries to the grid. That means millions of electricitystorage units – the batteries – are available to the electric grid to serve peak demand, with the vehicles recharging during non-peak hours. EV owners don’t view their cars as devices that store energy for someone else’s use.
When wind and sun are plentiful, excess clean energy can be stored in the batteries of EVs that are parked and connected to smart chargers. Stored energy is discharged from EV batteries at peak demand or when renewable energy availability is reduced.
It optimizes energy consumption based on grid constraints, energy pricing, renewable energy availability, locally stored energy, preconfigured EV owner preferences, and driver needs. The energy from the EV batteries is available to the electric grid to serve peak needs, with the vehicles recharging during non-peak hours.
For some (not all) use cases, the economic advantages of going electric have been clear for a long time, and yet we’ve seen a dozen EV manufacturers go bust while trying to address the commercial market, while fleet operators continue to buy diesel vehicles, which continue to belch out clouds of oily black smoke. megawatt chargers?
