/r/EnergyStorage
A reddit focused on the storage of energy for later use. This includes things like batteries, capacitors, super-capacitors, flywheels, air compression, oil compression, mechanical compression, fuel tanks, pumped hydro, thermal storage, electrical storage, chemical storage, thermal storage, etc., but also broadens out to utilizing 'more-traditional' energy mediums... where their focus is on their energy storage potential for later use, including even using 'the grid' for storage.
The Energy Storage Reddit
Energy storage is accomplished by devices or physical media that store energy to perform useful operation at a later time. A device that stores energy is sometimes called an accumulator.
All forms of energy are either potential energy (e.g. Chemical, gravitational, electrical energy, etc.) or kinetic energy (e.g. thermal energy). A wind-up clock stores potential energy (in this case mechanical, in the spring tension), a battery stores readily convertible chemical energy to operate a mobile phone, and a hydroelectric dam stores energy in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy) at night to meet peak demand for cooling. Fossil fuels such as coal and gasoline store ancient energy derived from sunlight by organisms that later died, became buried and over time were then converted into these fuels. Even food (which is made by the same process as fossil fuels) is a form of energy stored in chemical form.

BESS Capex
Hi all,
I’m hoping to learn more about the Capex (historical & future estimates) for a typical 4-hr BESS projects. I know it’s always difficult to generalize things, especially for a fast-changing industry like Energy Storage, but I would appreciate any inputs or if you could point me to sources. I already have figures from BNEF and NREL, but hoping to gain more data points.
Thank you very much!

SINGLE CELL OF THE BATTERY CAN BE REACHED UL9540A CERTIFICATION
I am very pleased to share with you this Sodium nickel sodium chloride battery ——a niche battery, can be reached UL9540A certification. The details of the specification was showed, and is anybody who clearly knows how this battery works or has just heard about it?

Follow up on CAISO the price spread from bid to charge and discharge is $235 per MWh on average. Does that mean I will make $235 MWh per day on average. Even though the average per year is $78 per KW?

Average revenue per kilowatt per year is $78 what is that in terms of megawatt hours?

Financing for Energy Storage
Hi all - I'm work on a startup idea that focuses on aggregating data in order to help banks and developers better underwrite storage projects. It's my understanding that there's no standard dataset or tool today that does projections and forecasting unlike say solar. Do you think such a solution would solve a real pain-point in the industry or do you think the idea is not practical due to the complexity involved? Thanks!
