Compressed Air Energy Storage

CSEF · 2017 Alternative Energy (Junior Division Only)

Ximena E. Greatorex · Alianza Charter School, Watsonville, Santa Cruz County

Overview

Objectives/Goals The objective of this project is to design a compressed air energy storage system that could replace batteries in a more environmentally responsible way. Methods/Materials 3D printed fan blades, shaft with bearings, electric motor (to be used as a generator), and tested with air compressor. Results By increasing the pressure on the air source, my output voltage of the turbine generator also increased. Conclusions/Discussion Based on my data I realized that the idea of Compressed Air Energy Storage is feasible. The problems with efficiency will need to be fixed before it can be used on a larger scale, particularly with the design of the turbine blades and the electric motor.

Summary statement

I showed that a compressed air turbine can be used to regain energy stored as compressed air.

Help received

My father helped me with knowledge of engineering and purchasing materials.
