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.

Residential Battery Storage Users.

Hi everyone,

I am looking to speak with users of Residential Battery Storage Products. It would be a paid consulting call looking to discuss your experience as an owner and user. Would anyone be interested?

ESS/ Energy Storage System / Solar System for your home

Usually people will buy this for household use, it's with a 5kw inverter, each battery with 5kwh, you can combine, 5kw +5kwh system, or 5kw + 10kwh system, or add more, When there is power goes out where you live, this can be used as power supply.

Would two 2KWH Power Stations qualify for the new US tax credit that requires a minimum of 3KWH battery storage?

I live in the US, and I want a backup battery for essential circuits in my house; e.g. refrigerator, lights, computer, and microwave. So not a whole-house backup like a powerwall, but enough to get through a one-day outage without having to just sit in the dark doing nothing. I am looking into semi-portable power stations like Bluetti or EcoFlow that don't require installation, so you pay approximately the same per KW for the storage, but save $5K on the installation, at the cost of having to string an extension cord when you're actually using it. Since outages of over an hour only happen once a year or so where I live, I'm very happy to make that trade-off.

The new Biden tax credit for battery backups requires that the unit store at least 3 KWH. My question is, if you buy two units of 2KWH each, would they consider that a 4KWH backup and allow the credit, or do they not allow adding the capacity of separate units?
