name 3 factors engineers consider when deciding to choose a energy storage.
Storage Capacity
Efficiency
Cost
Lifetime
Environmental Impact
Application Requirements
what is the name of the popular hydro dam in the USA
Hoover Dam
why are flywheel storage kept in a vacuum and use magnetic bearing ?
because it reduces air resistance and friction.
what is the average efficiency for thermal storage energy
50-90%
What is Energy Storage ?
Energy storage is the process of capturing energy produced at one time and saving it for use at a later time.
hydrogen powered vehicles use which type of energy storage
Chemical Energy Storage – Fuel Cells
What formula is used calculate energy stored in a flywheel and two main components of a flywheel storage.
KE = 1/2 * I * ω
any of theses
vacuum , generator/ motor , active magnetic bearing
