Energy Storage

Basics

• The storage of electrical energy
• Most often by conversion to another form of energy, for later conversion back to electricity

Methods

Chemical

• Batteries
• Flow Batteries
• Battery Banks

Physical

• FES
• Gravity Battery
• Pumped Hydroelectric Storage

Regenerative and Efficient Options

Solar Option

Direct solar power is efficient. Solar thermal and Saturated Water storage are in OSE's view the most appropriate, based on abundance and efficiency.

OSE proposes energy storage via a combined system consisting of solar thermal concentrators followed by PV heating assist to generate saturated water at 200/200 PSI/degrees C.

This is one of those options that are completely open source and nonstrategic, hence will not likely appeal to venture capitalists, as anyone can do it. The cost and performance are superior to battery storage when lifecycle stewardship is considered.

Thermal systems provide the necessary hot water, and PV is used to top it off. PV on cloudy days can also be used for topping off. Thermal energy is converted to electricity via a steam cycle for night time energy storage, just like in modern power plants.

Solar Hydrogen Option

Solar hydrogen is another abundant and nonstrategic resource. Storage vessels, high pressure pumps, and hydrogen burning engines are all proven technologies. These can result in cost effective hydrogen storage for electricity generation. The solar hydrogen economy can be implemented today.

Regenerative Options

Biomass to charcoal, compressed hydrogen, and saturated water appear to be the best energy storage options for night time power. All of these sources can be carbon neutral.
