There are many different ways in which you can store energy and this got me wandering about the options, efficiencies and the applications. Some of the applications are not always obvious, but a lot of different systems are used in engineering and in models.
Starting with the fundamental energy storage categories and sub-categories:
- Compressed air
- Hot water tank
All of these have advantages, disadvantages, efficiencies and costs. In order though to do more calculations it is necessary to often size the system. So let’s stay with the model world and think about an application for a model where I need 750W peak (approximately 1 brake horsepower) and that I need to be able to deliver 250W of power continuously for 20 minutes, so that equates to ~83Wh of useable energy.
This will also allow us to plot and compare power versus energy storage capability.
